The subject of this research is the peculiarities of structuring and reproduction of cultural traumas in the environment of migration communities. Based on the national and foreign studies of migration sphere of the modern German society, as well as a series of empirical research carried out the author in two federal lands of the Federative Republic of Germany, analysis is conducted on the specificity of structuring and reproduction of traumas of cultural memories among the refugees and forcefully displaced persons, ethnic and work migrants. The author compares the peculiarities of representation of cultural traumatic experience in migration and post-migration society. The use of systemic approach allowed determining the structure and constitutive relations between the key components of the process of reproduction and structuring of cultural traumas in migration environment. The structuring and reproduction of cultural traumas in migration environment depend on the position of receiving society and duration of stay of a migrant therein, specificity of the type of migration, intensity of contacts with the country of origin, as well as peculiarities of cultural memory of the country of origin. The novelty of this study consist not only in comparative analysis of the specificities of perception of the cultural traumatic experience within the environment of forcefully displaced persons, ethnic and work migrants of the modern Germany, but also juxtaposition of migration and post-migration society in the context of the questions of structuring and reproduction of cultural traumas. It is determines that the “post-migration society” contributes to transformation of the process of structuring of cultural traumas towards further fragmentation of the cultural traumatic experience, as well as emergence and dissemination of cultural traumas related to the most tragic pages in the history of humanity overall.

Abstract The role of municipalities in migrant integration in post-war European history has largely slipped below the radar in previous migration research. Our special issue presents case studies on how Bristol, Dortmund, Malmö, Mannheim, Stuttgart and Utrecht managed migrant influxes from the mid-1940s to 1960s. Following interdisciplinary advances in local migration studies, our urban histories take a diversity of approaches, present diverse temporalities, and uncover municipal responses that range from generosity to indifference and to outright hostility. In all six cities, despite such diversity in local attitudes and municipal policies, municipal authorities had significant impacts on migrants’ lives. The introductory article explores how our urban perspectives contribute to scholarship on reconstruction and the post-war boom; welfare; democracy and citizenship; and European integration. Using local migration as a lens into postwar European history, we argue, provides important new insights for the historiography of postwar Europe.

This article builds on the recent discussion about migrants’ post-migration mobilities. Although existing studies show the types and patterns of movement that migrants undertake, less attention has been paid to the question of how these movements influence their sense of belonging, their self-understanding and their perception of their origins. On the basis of 47 autobiographical interviews with young adults of Polish heritage in Germany and Canada, this article argues that belonging in times of post-migration mobilities can be grasped through the concepts of contextual self-understanding, accumulating and travelling origins. It thus extends conceptual frameworks by endeavouring to understand the effects of mobility on migrants’ lives.

Nadezda Shapkina
With the collapse of the socialist model in the former Union of Soviet Socialist Republics (USSR) in 1991 which was followed by Civil War (1992-1997), Tajikistan has undergone profound social, economic, and political transformation. Persistent impoverishment, political and economic instability, and discrimination of ethnic minorities have resulted in out-migration of Tajik population to Russia. In this study, labor migration (survival driven, seasonal, and chain) is discussed. Even though Tajik migrants face challenges such as segregation, xenophobia, sexism, and intolerance working abroad, they continue to migrate to Russia in order to seek a better quality of life. This is closely linked to migration policy and regulations that have been implemented by the governments of these countries which allow free movement across the borders. Although these migration policies promote legal migration, they create favorable conditions for inequality (such as structural, social, and global) as well as illegal migratory flows. However, little scholarly work has been focused on how migration policy contributes to structural inequality and leads to illegal migration in the former Soviet Republics. In my study, I seek to add to the limited existing literature about these phenomena. I examine the social context of Tajik labor migration, legal framework, migration policy and regulations, and its implications. Specifically, I analyze the case of Tajikistan and Russia’s migration policies and regulations as they are proposed and implemented by governmental agencies in collaboration and consultation with civil society organizations (local and international) including the Tajik diasporas.

Post-Apartheid South Africa has seen xenophobic sentiments towards migrants increase, culminating in several deadly riots. The words of equality and diversity, nurtured during the fight for independence seem to be far away. Building on Micheal Neocosmos theories on South African Xenophobia as a political discourse, this thesis examines how nationalist discourse creates and sustains negative perceptions of migrants. Using theories on national identity to undertake a critical discourse analysis of South African parliament proceedings, it illustrates how the perception of a civic and democratic nation, naturalizes a dichotomy between migrants and citizens. How the narrative of an equal and free South Africa, relies on the opposite perception of neighboring countries, as chaotic, undemocratic and un-free, resulting in a negative view of migrants. It argues that the opposing discourse of Pan-Africanism provides an opportunity in which a more inclusive identity can be built. Finally this thesis wishes to contribute to further research on national identity construction, by proposing a four-dimensional framework of exclusion that provides a reference point for contrasting national discourses

As Canada, and particularly metropolitan cities like Montreal, becomes increasingly diverse, it is important to explore and understand the culture and needs of immigrant communities. This Masters thesis focuses on the mental health of South Asian immigrant women in Montreal, Quebec. This original research is a qualitative descriptive study based on in-depth interviews with nine women from India and Pakistan. The interviews focus on the intersection of gender and culture with post-migration experiences, help-seeking patterns and coping strategies for distress in South Asian women. The women's narratives provide pertinent information for researchers and practitioners that could be applicable to the design of future research, outreach, health promotion, and models of care on mental health. The following four chapters provide a thorough discussion of the methodology, findings and conclusions.

My dissertation research was a 14-month ethnographic study of the post-repatriation experience of forced migrants in South Sudan. It was designed to determine if alterations to gender norms and relations that refugees experienced during asylum differed as a function of the asylum environments and if these modifications remained intact upon the refugees’ return. The forced migrants in my sample, the Dinka of Bor from South Sudan, encountered two different asylum environments and experiences: Kakuma refugee camp in northern Kenya and Khartoum, in northern Sudan. After 10-15 years in asylum, these forced Dinka Bor migrants returned to South Sudan. I compared the pre-flight and post-repatriation behavior of these two groups of returnees to determine to what extent gendered behaviors could be attributed to each asylum location. I found that various global forces encountered during asylum were instrumental in forging new ways of life by changing gendered livelihood practices and gendered access to status, power, and resources after return. In addition, the resettlement context played an equally critical role in the gendered behaviors after return.

Hindu Indian Bengalis as an ethno-linguistic and transnational group have negotiated their social locations historically, contemporaneously, and transnationally. In this dissertation, I examine and argue how transnational migration is the most recent in a long line of Bengali strategies to negotiate their social location vis-à-vis other populations in India. Since the early years of the nineteenth century, in Bengal specifically, a series of socio-political dynamics have reshaped and reconstituted Bengali social status. These dynamics can be observed across various geographic scales - national, regional, and local -- and have continued to inform their contemporary gender relations. En route to this examination, the dissertation exposes assumptions about who constitutes families, problematizes "family" centrally en route to examining spousal relations among Indian-Bengalis. I have examined the lived realities and experiences of migrant spouses in the U.S. and their family living in India amidst differing—and often conflicting-- imaginaries and practices of families. Through my work, I thus illustrate that family and marriage relations can be, and often are, strategic and fluid even as many people view them as structural and enduring. Over time, representations of the idealized Bengali family, of manhood and of womanhood have all shifted, reflecting sociopolitical and economic changes. A constant, however, has been the central role of gender in all these imaginaries and realized configurations. In this dissertation, I employ a "gendered optic," a heightened sensibility to what they communicate about gender. As I examine in my work, gendered boundaries amid the Bengali population can be found in a deeply rooted history, a colonial legacy, and one, although repackaged, that continues to be seen contemporaneously. Bengalis' transnational negotiations in family and marriage expand our understanding of transnational gender relations across broad social and historical scales, particularly the transnational. In this vein, the dissertation contributes significantly to the field of gender studies, specifically the field of feminist theorizing and intersectionality studies, postcolonial and South Asian studies, and to the scholarship on migration and transnational migration studies.

Haitian university students represent a part of the increasing diversity of Haitian migrants in the Dominican Republic. Using an ethnographic approach, I explore university students’ motivations for studying in the Dominican Republic, their experiences at Dominican universities and in Dominican society, Haitian student organizations, and their future plans. Additionally, I focus on Haitian students’ experiences with discrimination and how they relate to other Haitian migrants in the Dominican Republic. I find that most students come to the Dominican Republic due to the difficulty of gaining entrance to affordable Haitian universities and logistical convenience. The university is a unique setting where Haitian and Dominican students are clearly peers, which results in increased interactions between the two groups and decreased discrimination towards Haitian students. However, Haitian students remain a relatively isolated group within the university and in the larger Dominican society. Many students reported experiencing discrimination, although students identified class, rather than race or nationality, as the main reason for discrimination. Furthermore, I focused on the role of language in migrants’ experiences. I found that while a high command of Spanish allowed migrants to avoid identification as Haitian and subsequent discrimination, Kreyòl was used as a resource to create solidarity and maintain cultural ties to Haiti. My research suggests that it is important to keep in mind the distinct notions of race and nationality in Haiti and in the Dominican Republic when considering contemporary struggles for the rights of Haitian migrants and their descendants in the Dominican Republic.

This is an ethnographic case study, based in participant observation, which investigates and analyzes how the everyday relationships between Europeans, South Americans expatriates & Angolan nationals, are structured in a common transnational labor community in Angola, named Cambambe. This study investigates if there are any features of post-colonial power relations that affect and shape the interactions between those three communities. Thus, if the contemporary forms of relationship, as expressed by this community, can still be compared to that old hard power stereotype namely labor relations from the colonial past, or if those have changed with modernity. In doing so, this study equally analyzes not only how the interactions between the three communities is expressed in terms of identity, culture and ethnic belonging, but also how such expressions bring about tangible consequences for the groups relating to their social and institutional positions inside the working community. Furthermore, this study examines if the three group populations are able to go beyond their ethnic and cultural boundaries in order to create common zones of togetherness and empowerment, and if so, how these zones are shaped. To do so, the analysis observes how the intergroup perceives power into their relational context, focusing in four dimensions, namely; rationality, perceived justice, material resources and identity. Moreover, this is a multidisciplinary analysis which makes use of the theoretical lenses provided by the post-colonial theory, psychology of intergroup relations and power theories in international relations, to shed light into the understanding of contemporary labor communities and in the position of the post-colonial subjects in society in a North to South perspective.

AbstractThe Introduction sets this book in the wider context of recent studies and public interest in historic child abuse. Noting other international cases of child abuse in the context of public programmes and other institutional contexts, it is argued that children’s suffering usually arose not from an absence of policy and legal protections but a failure to implement these effectively. The assisted migration of unaccompanied children from the United Kingdom to Australia is presented, particularly in the post-war period, as another such example of systemic failures to maintain known standards of child welfare. The focus of the book on policy decisions and administrative systems within the UK Government is explained and the relevance of this study to the historiography of child migration and post-war child welfare is also set out.

AbstractRecently, a burgeoning literature has emerged on the return experience of migrants, with some analysts touting the benefits of return to the socioeconomic development of countries of origin, especially in Sub-Saharan Africa. Still, only few studies have examined how return migrants create and sustain transnational connectivity with their countries of destination upon their return to the homeland, and fewer still have analyzed how these dynamics play out in the context of West African migrants. This primarily theoretical paper explores the interconnections between return migration and transnationalism among West African migrants, focusing on the case of Ghanaian and Senegalese migrants. The insistent premise of the paper posits that contemporary migration is essentially Janus-faced, in the sense that migrants are transnational in both their pre- and post-return periods. The paper addresses the following questions: (i) What are the perspectives of Northern countries and supra-national bodies, such as the EU, on return migration, and how do these perspectives compare with those of Southern countries, such as Ghana and Senegal? (ii) How do West African migrants view their own return migration, and to what extent are their emic perspectives different from those of Northern governments and their government in the homeland? (iii) How do West African returnees—specifically, Ghanaian and Senegalese returnees—use their transitional connectivities to facilitate their resettlement and reintegration in the homeland upon their return? Clearly, return migration elicits a number of important questions, into which this Chapter stands to provide useful preliminary prescience in the context of Ghanaian and Senegalese migrants.

Custom 3D printed titanium acetabular implants have only recently been introduced and enable surgeons to treat traditionally unreconstructable massive acetabular defects. Whilst there is an accepted threshold for implant migration (proximal translation of >1 mm within 2 years) that constitutes loosening in primary and revision uncemented hip implants, there is no reference threshold for custom acetabular implants used to treat massive defects, with no long-term outcome studies [1]. Aim: We performed bone-to-bone registration of sequential CT imaging with the aim to help define radiological loosening of custom-made three- dimensionally 3D printed trabecular titanium cups for the management of massive acetabular defects. Objectives: Our primary and secondary objectives were to assess implant position and orientation 1-year post surgery in comparison with the immediate post-operative CT imaging.

Abstract Field D (offshore Sarawak, Malaysia) first production was in 2012 from three wells, with a second phase of development in 2017 with the drilling of four wells. Severe productivity decline was seen in five of the seven wells, and numerous studies were completed to narrow in on the root causes. Several production enhancement techniques were executed on Phase 1 and Phase 2 wells, where learnings and results will be further shared. Prior to the drilling of six additional wells in Phase 3 (2020), additional detailed lab studies were undertaken, and new strategies were implemeted based on this were applied with encouraging results. The majority of the wells have downhole pressure gauges (PDG), and coupled with frequent well test data, PTA, and Nodal Analysis modeling Productivity Index, permeability thickness (kH), and Skin are able to be tracked over time. By trending these different productivity indicators, it became clear that formation damage was occurring in several wells with varying degrees of severity based on the performance of the reservoir layer being produced. Various formation damage mechanisms were assessed (scale, wax, asphaltenes, drilling & completion damage, fines migration), and based on the initial study it was determined that fines migration was likely the major issue. Historically, no sand was observed on the surface where monthly sand count reported has always been <1 pound per thousand bbl (pptb) which was supported by geomechanics, and sand failure tendency studies completed during development phase of the field. Hence, six of the seven Phase 1 and 2 wells were completed with cased and perforated strategy with no downhole sand control, with the other well completed as a highly deviated open hole standalone completion. The productivity declines were only experienced in the cased and perforated completions, which had much lower gross completed interval and thus experienced higher velocities near the wellbore. The main production enhancement strategy applied to date has been re-perforation (8 re-perforation jobs), with varying degrees of productivity improvement and duration of sustainability. Solid propellant technology was applied in one of the well and clearing of the perforation tunnels via through-tubing dynamic underbalance technique in two wells was applied and no major improvement in sustained production impact was observed. An acid stimulation was recently pumped for the first time in one well and the assessment details will be shared, and results of the pumping will be shared in detail. At the time of the paper, no post production results were available. Prior to the drilling of six Phase 3 wells in 2020, detailed lab studies to look at the impact of various drilling muds were assessed, and learnings were incorporated in the mud program. Critical velocity studies were completed, and learnings from this work such as well ramp-up strategy and normalized maximum production rates have been added to the well-by-well production strategy. Based on Phase 3 production data to date, application of these new learnings has resulted in no major productivity decline seen. The learnings from D field would benefit other operators by sharing the lessons learned on assessment of formation damage mechanisms, the results of the different type of production enhancements applied, and the successful mitigation strategies for future wells (lab assessment, mud strategy change, and production strategies to prevent plugging due to fines migration).

Abstract Current standards for testing cemented femoral hip stems involve potting the distal third of the stem and applying a cyclic load, see ISO 7206-8. 1995(E). However, this procedure does not test implants for the most prevalent mode of failure — loosening of the prosthesis from the host bone (Malchau et al., 1993). To quantify the expected longevity of implants in a pre-clinical test, a protocol that establishes the rate of loosening of a prosthesis must be developed. Using Radiostercophotogrammetry (RSA), Karrholm et al. (1994) have correlated migration of more than 1 mm within two years of implantation with early loosening of the implant. Therefore, by quantifying the migration of a prosthesis in a laboratory test for the equivalent of two years post implantation, its risk of loosening in vivo can be assessed. In the past, the motion of cemented implants in one direction has been quantified (Manley et al., 1987); whilst other researchers have performed a more complete analysis of the motion of prostheses, but for a limited number of loading cycles (e.g. Schneider et al., 1989). In most of these studies, prosthesis insertions were performed by surgeons. Not only does this introduce subjectivity into the pre-clinical test, but in the case of cemented replacements, variations in stem orientation and cementing pressures will occur. This paper presents the design and initial validation of procedures which may be used for pre-clinical testing of cemented hip stems.

Carpal tunnel syndrome is conventionally treated by open and endoscopic release surgeries in which transecting the transverse carpal ligament (TCL) relieves mechanical insults around the median nerve. The TCL release surgeries yield an increase in the tunnel cross-sectional area particularly within the volar aspect of the tunnel, the arch area, where the median nerve is located. As a result of increased arch area, post-operative follow-up studies using MRI confirmed a significant volar migration of the median nerve [1]. However, transecting the TCL compromises critical biomechanical roles of the carpal tunnel [2], and therefore, it is imperative to investigate an alternative method for treating carpal tunnel syndrome patients while preserving the TCL. Li et al. suggested that increasing the TCL length and narrowing the carpal arch width (CAW) as potential alternatives for increasing the arch area [3]. However, the data from their application of palmarly directed forces to the TCL from inside of the tunnel showed that the TCL length remained relatively constant while the carpal bones were mobilized to increase the arch area [3]. The purpose of this study was to investigate the relationship between CAW narrowing and the TCL-formed arch area by experimental and geometrical modeling.

Abstract CO2 sequestration is a process for eternity with a possibility of zero-degree failure. Monitoring, Measurement and Verification (MMV) planning of CO2 sequestration is crucial along with geological site selection, transportation and injection process. Several geological formations have been evaluated in the past for potential storage site which divulges the containment capacity of identified large, depleted gas reservoirs as well as long term conformance. Offshore environment makes MMV plan challenging and demands rigorous integration of monitoring technologies to optimize project economic and involved logistics. The role of MMV is critical for sustainability of the CO2 storage project as it ensures that injected CO2 in the reservoir is intact and safely stored for hundreds of years post-injection. Field specific MMV technologies for CO2 plume migration with proactive approach were identified after exercising pre-defined screening criteria. Marine CO2 dispersion study is carried out to confirm the impact of any potential leakage along existing wells and faults, and to understand the CO2 behavior in marine environment in the event of leakage. Study incorporates integration of G&G subsurface and Meta-Ocean & Environment data along with other leakage character information. Multi-Fiber Optic Sensors System (M-FOSS) to be installed in injector wells for monitoring well & reservoir integrity, overburden integrity and monitoring of early CO2 plume migration by acquiring & analyzing the distributed sensing data (DTS/DPS/DAS/DSS). Based on 3D couple modeling, a maximum injection rate of approximately 200 MMscfd of permeate stream produced from a high CO2 contaminated gas field can be achieved. Injectivity studies indicate that over 100 MMSCFD of CO2 injection rates into depleted gas reservoir is possible from a single injector. Injectivity results are integrated with dynamic simulation to determine number and location of injector wells. 3D DAS-VSP simulation results show that a subsurface coverage of approximately 3 km2 per well is achievable, which along with simulated CO2 plume extent help to determine the number of wells required to get maximum monitoring coverage for the MMV planning. As planned injector wells are field centric and storage site area is large, DAS-VSP find limited coverage to monitor the CO2 plume. To overcome this challenge, requirement of surface seismic acquisition survey is recommended for full field monitoring. An integrated MMV plan is designed for cost-effective long-term offshore monitoring of CO2 plume migration. The present study discusses the impacting parameters which make the whole process environmentally sustainable, economically viable and adhering to national and international regulations.

Abstract Positive geological and geochemical prerequisites have been identified for the purpose of increasing hydrocarbon resource potential in the under-explored study area. A methodology has been developed for assessing the hydrocarbon potential and prospecting for new promising oil and gas accumulation zones using the technology of basin modeling, provided there is a lack of initial data. A high hydrocarbon source rock generative potential and the degree of thermal maturity of the Lower Permian, Mid Carboniferous and Upper Devonian strata of the south-eastern part of the Precaspian depression have been revealed. Seismostratigraphic interpretation and geodynamic analysis were carried out and the main stages of the geodynamic evolution of the study area were reconstructed based on combination of all available geological and geophysical information, recent exploration drilling results and unpublished subsurface studies. The results of thermotectonic modelling confirm the possibility of vertical migration of hydrocarbons generated in Upper Paleozoic source rocks. A revision of the previously performed interpretation of 3D seismic data has been carried out; and for the first time, intrasalt sedimentary packages of presumably Upper Permian age have been identified as independent objects, which can be potential hydrocarbon traps. For the Lower Permian deposits, type III kerogen predominates, which may be associated with an increase in collisional processes in the Late Paleozoic time and an active input of plant organic matter. For Mid Carboniferous sediments, type II or mixed type II / III kerogen prevails. Analysis of the evolution of thermal maturity indicates the unevenness of the entry of potential source rocks into the main zone of oil generation. For kerogen type III of the Lower Permian source rocks, the peak of oil generation falls on the Late Cretaceous. For predominantly carbonate and terrigenous-carbonate Middle Carboniferous source rocks the peak of generation falls on the Jurassic. The most buried Devonian source rocks presumably entered into the zone of wet gas generation. The development of salt tectonics from Late Triassic to Cenozoic contributed to the vertical migration of hydrocarbons into the post-salt complex. The identified petroleum accumulations in the Upper Triassic-Jurassic stratigraphic section are mainly confined to the four-way dip structural closures above the steep flanks of salt diapirs.

Abstract Repeated time-lapse Walkaway VSP (vertical seismic profile) were acquired as part of CO2 WAG EOR pilot monitoring in an onshore carbonate field in the UAE. The Baseline survey followed by two monitors were acquired, one after 6 months of water injection and another after 3 years of CO2/Water injection cycles. Objectives were to monitor CO2 and Water fronts between injector and producer, in addition to assess source and receiver repeatability. Feasibility study was performed to estimate 4D effects due to petrophysical changes in the reservoir, resulting from Water and/or Gas injection. After performing the survey design for receiver and source positions, 36 level 3C receivers at 7.6 m spacing array were deployed few hundred meters above the reservoir. Baseline and Monitor-1 survey were acquired with 186 source points at 25 m spacing, with maximum offset of 3000 m from wellhead in both directions along NW-SE line, however, Monitor-2 had 10 source points less in NW direction due to surface restrictions. Excellent data quality with good repeatability was achieved. Final images around reservoir showed no visible seismic 4D changes along Walkaway VSP orientation post injection during period between Baseline and Monitor-1, possibly due to fluid transmission not proceeding along this orientation, or it was too early to detect anomalies in the vicinity. This paper presents Baseline/Monitor-2 processing results. 3C VSP processing was performed while taking into consideration Baseline and Monitor-2 data NRMS (normalized root mean square) and predictability at major processing steps. Customized processing workflow was applied for wavefield separation and deconvolution. VSP geometry is lacking high angle first arrivals to directly estimate overburden shales anisotropy parameters, which was addressed by incorporating the values from literature. Cross-equalization was performed pre-migration i.e. scalars computed on downgoing wavefield and applied on upgoing wavefield. Time-lapse analysis was performed pre-migration i.e. on NMO (normal move out) corrected data after flattening at overburden shales to remove any time shift effects from the overburden. Time shifts were noticed across receivers in the overburden shales in Walkaway VSP and validated by Zero-Offset VSP extracted from the Walkaway VSP. The observed time shifts were small with no amplitude differences on NMO corrected data at the reservoir. In the migrated images, amplitude difference observed were possibly due to these time shifts, these slight time changes are stacked in the migration process and hence compounded with the 4D amplitude signature of the images. Time-lapse feasibility studies are available in the literature however; actual time-lapse seismic surveys are very limited in the UAE. This study will help the operators to deploy borehole seismic technology for time-lapse monitoring in the Middle East carbonate reservoirs. Processing workflow was optimized, highlighting challenges and limitations posed by the survey geometry with future recommendations.

Abstract Natural gas is the noble fuel of 21st century. Consumption increased nearly 30% in last decade. Exploitation of conventional, unconventional, and contaminated gas resources are in focus to meet the demand. There are number of giant gas fields discovered worldwide and some of them with higher degree of contaminants viz. CO2, H2S and Hg. Additionally, they have operating challenges of high pressure and temperature. It becomes more complex when discovery is in offshore environment. This study presents the development and production, separation, transportation and identification & evaluation of storage sites and sequestration and MMV plan of a giant carbonate gas field in offshore Malaysia. Geological, Geophysical and petrophysical data used to describe the reservoir architecture, property distribution and spatial variation in more than 1000m thick gas bearing formation. Laboratory studies carried out to generate the rock and fluid representative SCAL (G-W), EOS and Supercritical CO2-brine relative permeability, geomechanics and geochemical data for recovery and storage estimates in simulation model and evaluating the post storage scenario. These data are critical in hydrocarbon gas prediction and firming up the number of development wells and in the simulation of CO2 storage depleted carbonate gas field. Important is to understand the mechanism in the target field for storage capacity, types of storage- structural and stratigraphic trapping, solubility trapping, residual trapping and mineral trapping. Study covers methodologies developed for minimization of hydrocarbon loss during contaminants separation and utilization of CO2 in usable products. Uncertainty and risk analysis have been carried out to have range of solution for production prediction and CO2 storage. Coupled Simulation studies predict the production plateau rate and 5 Tscf recovery separated contaminants profile and volume > one Tscf in order to have suitable geological structure for storage safely forever. Major uncertainties in the dynamic and coupled geomechanical-geochemical dynamic model has been captured and P90, P50, P10 forecast and storage rates and volumes have been calculated. Results includes advance methodologies of separation of hydrocarbon gas and CO2 like membrane and cryogenics for bulk separation of CO2 from raw gas and its transportation in liquid and supercritical form for storage. Study estimates components of sequestration mechanism, effect of heterogeneity on transport in porous media and height of stored CO2 in depleted reservoir and migration of plume vertically and horizontally. Generation of chemical product using separated CO2 for industrial use is highlighted.

Hydrogen sulfide (H2S) is a toxic and corrosive gas that commonly occurs in deeply buried sedimentary systems. Understanding its distribution is paramount to creating safe and effective models of H2S occurrence aiding in the identification of high-risk areas. Characterizing subsurface sulfur sources and H2S formation pathways would enhance these models leading to more accurate predictions of potential high H2S regions. However, gaps remain in our understanding of the dominant formation processes and migration pathways of key ingredients for H2S production in the Lower Triassic Montney Formation of the Western Canada Sedimentary Basin (WCSB). Essential to this is assessing the reactants necessary for H2S production, potential pathways for fluid migration, diagenetic history, and changes in redox conditions through time. The Montney Formation has undergone several phases of diagenesis related to post-depositional alteration and multiple cycles of tectonic burial and uplift. Early chemical alteration includes dolomitization and, in some cases, microbial reduction of porewater sulfate to sulfide that occurred prior to significant burial (Davies et al., 1997; Vaisblat et al., 2021; Liseroudi et al., 2020, 2021). The most recent tectonic-related burial during the Laramide Orogeny resulted in burial depths in excess of 3-5 km (Ness, 2001; Ducros et al., 2017) leading to significant thermal and barometric alteration. Associated with this orogenic activity was the reactivation of underlying faults (O'Connell et al., 1990) and development of fractures especially near the deformation front. These fractures provide conduits for fluid migration into the Montney that combined with heat and pressure resulting in hydrocarbon generation, migration, and development of overpressure, notably in the western margin of the basin. In addition, high temperatures resulted in thermochemical sulfate reduction (TSR) leading to the formation of H2S and subsequently pyrite. We present an interpretation of the Montney subsurface sulfur cycle through the use of petrography, micro- and macro-scale geochemical analysis (isotopic and elemental) to illustrate the complexity of this system. This work relies heavily on previous studies within and outside our research group and incorporates new analytical techniques to expand the toolbox. We aim to guide future research directions and activities by addressing issues related to sampling and data quality issues, analytical approaches, and highlight knowledge gaps.

The Women, Peace and Security or Gender Peace and Security (WPS/GPS) agenda has expanded significantly over the 20+ years of concerted efforts at many levels to expand the role of women in conflict resolution and peacebuilding. Yet many authors note that the expansion of international agreements and national plans to support greater women’s participation in decision-making have yet to translate into concrete changes. This report examines progress in promoting women’s meaningful participation in decision making processes in conflict prevention and peacebuilding, with a focus on changes since 2018. Evidence on women’s meaningful participation in decision-making tends to focus on a small range of measurable outcomes with some studies considering the outcomes of women’s involvement in those processes to determine the extent to which they might be ‘meaningful’. Few studies examine differential outcomes of such initiatives for different groups of women, and most data does not allow for the disaggregation of intersecting identities between gender, ethnicity, race, disability, migration status and other key factors. Evidence collected for this report suggests that policies and programmes seeking to support greater women’s participation in decision-making in conflict prevention and peacebuilding often struggle to address the broader structural factors that inhibit women’s empowerment. Tackling longstanding and often deeply embedded harmful social norms has proven challenging across sectors, and in conflict or post-conflict settings with highly complex social dynamics, this can be especially difficult. Many of the issues highlighted in the literature as hindering progress on the WPS agenda relate to cross-cutting issues at the heart of gender inequality. Multiple authors from within women’s movements in conflict and post-conflict settings emphasise the need for policies and programmes that support women to act as agents of change in their own communities and which amplify their voices rather than speak on their behalf. Recent achievements in South Sudan and the Pacific region are indicative of the potential of women’s movements to affect change in conflict prevention and peacebuilding and suggest progress is being made in some areas, though gender equality in these processes may be a long way off.

Paleozoic platform carbonate rocks of the Rocky Mountains host Mississippi Valley-type (MVT), magnesite, barite, and REE-barite-fluorite deposits. Farther west, platform carbonate rocks of the Kootenay Arc host MVT and fracture-controlled replacement (FCR) deposits. This is the first systematic LA-ICP-MS study of carbonates in MVT and FCR deposits. We investigated seven MVT deposits in the Rocky Mountains, and five MVT deposits in the Kootenay Arc. None of the post-Archean Australian shale (PAAS)-normalized REE profiles show light REE (LREE) depletion and strong negative Ce anomalies characteristic of modern seawater: some profiles are nearly flat; others show depletion in LREE similar to seawater but without negative Ce anomalies; others are middle REE enriched. Carbonates with a strong positive Eu anomaly precipitated from or interacted with different fluids than carbonates with flatter profiles without a strong positive Eu anomaly. REE signatures reflect crystallization conditions of primary carbonates, and crystallization and re-equilibration conditions of carbonates with ambient fluids during diagenesis, deep burial, and/or metamorphic recrystallization. Chemical evolution of fluids along their migration path, fluid-to-rock ratio, fluid acidity, redox, and temperature also influence REE profile shape, which helps establish genetic and timing constraints on studied deposits and improves knowledge of the metallogeny of the Kootenay Arc and Rocky Mountains.
