Abstract:
PurposeThe Early Life Exposure in Mexico to ENvironmental Toxicants (ELEMENT) Project is a mother–child pregnancy and birth cohort originally initiated in the mid-1990s to explore: (1) whether enhanced mobilisation of lead from maternal bone stores during pregnancy poses a risk to fetal and subsequent offspring neurodevelopment; and (2) whether maternal calcium supplementation during pregnancy and lactation can suppress bone lead mobilisation and mitigate the adverse effects of lead exposure on offspring health and development. Through utilisation of carefully archived biospecimens to measure other prenatal exposures, banking of DNA and rigorous measurement of a diverse array of outcomes, ELEMENT has since evolved into a major resource for research on early life exposures and developmental outcomes.Participantsn=1643 mother–child pairs sequentially recruited (between 1994 and 2003) during pregnancy or at delivery from maternity hospitals in Mexico City, Mexico.Findings to dateMaternal bone (eg, patella, tibia) is an endogenous source for fetal lead exposure due to mobilisation of stored lead into circulation during pregnancy and lactation, leading to increased risk of miscarriage, low birth weight and smaller head circumference, and transfer of lead into breastmilk. Daily supplementation with 1200 mg of elemental calcium during pregnancy and lactation reduces lead resorption from maternal bone and thereby, levels of circulating lead. Beyond perinatal outcomes, early life exposure to lead is associated with neurocognitive deficits, behavioural disorders, higher blood pressure and lower weight in offspring during childhood. Some of these relationships were modified by dietary factors; genetic polymorphisms specific for iron, folate and lipid metabolism; and timing of exposure. Research has also expanded to include findings published on other toxicants such as those associated with personal care products and plastics (eg, phthalates, bisphenol A), other metals (eg, mercury, manganese, cadmium), pesticides (organophosphates) and fluoride; other biomarkers (eg, toxicant levels in plasma, hair and teeth); other outcomes (eg, sexual maturation, metabolic syndrome, dental caries); and identification of novel mechanisms via epigenetic and metabolomics profiling.Future plansAs the ELEMENT mothers and children age, we plan to (1) continue studying the long-term consequences of toxicant exposure during the perinatal period on adolescent and young adult outcomes as well as outcomes related to the original ELEMENT mothers, such as their metabolic and bone health during perimenopause; and (2) follow the third generation of participants (children of the children) to study intergenerational effects of in utero exposures.Trial registration numberNCT00558623.

Disseminating knowledge is an important element of practice in health psychology. This can help research to have positive impact in wider society. Digital technologies and social media create a plethora of available avenues for students to share research and practice, but it can be difficult to envisage how creative methods can be used to mobilise knowledge effectively with the public and stakeholders. A Creative Mobilisation workshop hosted at the DHP Conference for students aimed to address this topic.

Abstract:
This work presents a new macro-element model to predict the behaviour of Suction Embedded Plate Anchors (SEPLAs) for floating offshore structures during keying and loading stages. Differently from previously published models for anchors, this new model is characterised by (i) a non-associated plastic potential with the aim of improving the prediction of anchor trajectory for the whole displacement domain and for a large range of padeye offsets; and (ii) by a strain-hardening rule enabling to predict the force and displacement mobilisation from the early stages of the keying process. The model was calibrated against LDFE analyses and compared with a broad set of LDFE and centrifuge tests results. The model proves capable of reproducing anchor rotation and displacement with good accuracy for a wide range of padeye offsets and distinct studies from the literature.

Abstract:
The geologic storage of CO2 carries both physical and chemical risks to the environment. In order to reduce those risks, it is necessary to provide predictive capabilities for impacts so that strategies can be developed to monitor, identify and mitigate potential problems. One area of concern is related to water quality both in the reservoir and in overlying aquifers. In this study we report the critical steps required to develop chemically constrained reactive transport models (RTM) that can be used to address risk assessment associated with water quality. The data required to produce the RTM includes identifying the individual hydrostratigraphic units and defining the mineral and chemical composition to sufficient detail for the modelling. This includes detailed mineralogy, bulk chemical composition, reactive mineral phase chemical composition and the identification of the occurrence and mechanisms of mobilisation of any trace elements of interest. Once the required detail is achieved the next step involves conducting experiments to determine the evolution of water chemistry as reaction proceeds preferably under varying elevated CO2 fugacities with and without impurities. Geochemical modelling of the experiments is then used for characterising the reaction pathways of the different hydrostratigraphic units. The resultant geochemical model inputs can then be used to develop the chemical components of a reactive transport model.

Abstract:
La comparaison de la nature de 1674 mutants obtenus dans plusieurs contextes genetiques et conditions physiologiques, a montre que la mobilite des sequences is n'etait pas constante au cours de la croissance bacterienne. En milieu riche, la transposition des is est totalement absente en phase de croissance exponentielle, et ne se produit qu'en phase stationnaire. Ce phenomene semble etre independant du facteur de transcription rpos, specifique de la phase stationnaire. Cependant, la transposition peut se produire en phase de croissance exponentielle dans un milieu ou la croissance est ralentie par des carences nutritionnelles. Nous avons aussi identifie une region chromosomique impliquee dans la transposition. La deletion de cette region permet la mobilisation d'is1 et d'is5 des la phase de croissance exponentielle, mais il n'a pas ete possible d'affecter ce phenomene a un gene unique de cette region. L'hypothese formulee a l'issue de ce travail est que la transposition de certaines is est favorisee, lorsque le bon fonctionnement cellulaire est altere. Des donnees recentes montrent par exemple que le dysfonctionnement du ribosome en fonction des ressources nutritives augmente la transposition d'is1.

Abstract:
Manmade climate change has expressed a plethora of complex effects on Earth's biogeochemical compartments. Climate change may also affect the mobilisation of natural metal sources, with potential ecological consequences beyond mountains' geographical limits; however, this question has remained largely unexplored. We investigated this by analysing a number of key climatic factors in relationship with trace metal accumulation in the sediment core of a Pyrenean lake. The sediment metal contents showed increasing accumulation trend over time, and their levels varied in step with recent climate change. The findings further revealed that a rise in the elevation of freezing level, a general increase in the frequency of drier periods, changes in the frequency of winter freezing days and a reducing snow cover since the early 1980s, together are responsible for the observed variability and augmented accumulation of trace metals. Our results provide clear evidence of increased mobilisation of natural metal sources - an overlooked effect of climate change on the environment. With further alterations in climate equilibrium predicted over the ensuing decades, it is likely that mountain catchments in metamorphic areas may become significant sources of trace metals, with potentially harmful consequences for the wider environment.

Full text
Abstract:
L’alternance de périodes glaciaires et interglaciaires durant les 20 derniers Ma a mené à des changements environnementaux répétés au niveau du plateau continental antarctique. C’est dans ce contexte que les téléostéens de la famille des Nototheniidae se sont adaptés et diversifiés à travers plusieurs vagues de radiations (dont les Trematominae), dominant l’Ichtyofaune australe. Parmi les Nototheniidae, le groupe « Trematomus » (genres Cryothenia, Pagothenia, Trematomus et Indonotothenia) est celui où l’on observe la plus grande diversité chromosomique, avec des nombres diploïdes de chromosomes allant de 24 à 58, impliquant de nombreux réarrangements ayant accompagné les spéciations. Nous avons cherché à caractériser ces remaniements chromosomiques. Avec un caryotype ancestral inféré de 2n = 48, une conservation des unités chromosomiques entre espèces, et une constance des tailles de génome, l’hypothèse de réarrangements structuraux sans polyploïdisation préalable est la plus probable. Afin de reconstruire l’histoire évolutive de ces événements, nous avons recherché les homologies chromosomiques interspécifiques. Ceci nous a permis de reconstituer les remaniements (majoritairement des fusions) que nous avons repositionnés sur la phylogénie résolue des « Trematomus ». Contrairement à ce qui a été publié pour le genre Notothenia, nos résultats suggèrent des acquisitions multiples et indépendantes. Les éléments transposables (ETs) peuvent être impliqués dans les remaniements chromosomiques par le biais de recombinaisons ectopiques. Ils participent alors à la diversification des lignées au cours de l’évolution. En raison de leur régulation épigénétique, leur mobilisation massive peut être induite en cas de variations environnementales importantes. Nous nous sommes intéressés à trois super-familles d’ETs (DIRS, Gypsy and Copia) dans ces génomes. Les DIRS1 ont montré des patrons d’insertions en points chauds dans les régions centromériques et péricentromériques. Etant donné leur mode de transposition décrit et leur propension à s’insérer dans des copies préexistantes, nous proposons un rôle des éléments DIRS1 comme facilitateurs des fusions observées lors de la diversification des « Trematomus »
In the last 20 My, multiple glacial-interglacial cycles led to strong and repeated environmental changes on the Antarctic continental shelf. In this changing environment, nototheniid fishes diversified through several rounds of species radiation (one of which within Trematominae), and now constitute the dominant group in Antarctic teleosts. Among Nototheniidae, the group « Trematomus » (genera Cryothenia, Pagothenia, Trematomus and Indonotothenia) exhibits the highest chromosomal diversity, with diploid chromosome numbers ranging between 24 and 58, involving many rearrangements probably linked to speciation. We characterized the nature of these chromosomal repatternings. With an inferred ancestral state of 2n = 48 acrocentric chromosomes, a conserved number of chromosomal structural units, and a constancy of the genomes sizes we measured; the hypothesis of structural modifications is favored rather than a whole genome duplication associated to drastic reductions. In order to reconstruct an evolutionary scenario of such chromosomal rearrangements accompanying the trematomine diversification, we identified interspecific chromosomal homologies. This allowed us to reconstruct the rearrangements events (mostly centric and tandem fusions). We plotted them on a phylogeny we reconstructed based on our own ddRAD-seq data. Contrary to what was reported for the Notothenia, our results are in favor of independent acquisitions. Transposable elements (TEs) can lead to chromosomal rearrangements through ectopic recombination events, hinting at a role as drivers of specific-lineage diversification. Moreover, due to their epigenetic regulation, TEs can be mobilized when thermic changes occur. We focused on three retrotransposon superfamilies (DIRS, Gypsy and Copia) in nototheniid genomes. The DIRS1 showed unexpected accumulation patterns of insertion in the centromeric and pericentromeric regions. Given the mechanism of DIRS1 transposition and their tendency to sometimes insert on pre-existing copies (homing), we suggest a role of DIRS1 elements as facilitators of the fusions that occurred during the trematomine radiation

Thesis, Lyon, 2018. http://www.theses.fr/2018LYSET007/document.

Full text
Abstract:
Les sédiments urbains et résidus minier sont deux sources de pollution potentielle pour l’environnement et plus particulièrement les eaux de surfaces ou les eaux souterraines. L’altération chimique de ces interfaces solides par contact avec une source d’acidité ou d’alcalinité via l’air ou l’eau, est susceptible de se traduire par une dissolution des phases minérales et organiques et d’induire une mobilisation des éléments majeurs et traces métalliques. Ces mécanismes sont encore mal décrits et modélisés pour ce type de matrices très complexes. Cette thèse étudie donc le potentiel de mobilisation des éléments majeurs et traces métalliques de diverses interfaces carbonaté ou non carbonaté (pour l’étude du drainage minier acide et neutre contaminé). En supplément, des interfaces minérales pures ont été utilisées pour simuler en laboratoire des assemblages de phases et identifier les mécanismes croisés impliqués dans le drainage minier acide et neutre contaminé. Toutes ces matrices ont été soumises à des tests de capacité de neutralisation acido-basique (mise en contact avec une source de protons ou d’alcalinité), avec le suivi du pH (pouvoir tampon), de la conductivité et de la mobilisation élémentaire (majeurs et éléments traces métalliques). Les données expérimentales ont été modélisées avec le logiciel de spéciation géochimique PHREEQC. La combinaison des volets d’expérimentation et de modélisation, qui a très rarement été développé sur des interfaces solides aussi complexes, a permis l’identification (i) des réactions de dissolution des phases constitutives des interfaces polluées avec les réactions de sorption impliquées dans la mobilisation de leurs éléments majeurs et traces métalliques, (ii) de la spéciation des éléments majeurs et traces métalliques dans ces interfaces et dans les solutions en équilibre avec les phases solides. Ce travail de thèse permet donc d’aboutir à une méthodologie robuste, précise et réplicable permettant une caractérisation fine de la spéciation en phase liquide et solide des polluants métalliques dans les interfaces contaminées. Cette méthodologie constitue une base cruciale pour comprendre et prédire l’évolution des matières solides contaminées (sédiments urbains et déchets miniers) en fonction des différents modes de gestion : dépollution, valorisation et recyclage
Urban sediments and mine tailings constitute two potential sources of pollution for the environment, especially surface water or groundwater. The chemical alteration of these solid matrices by contact with a source of acidity or alkalinity via air or water is likely to result in the dissolution of the mineral and organic phases and to induce the mobilization of majors and trace elements. These mechanisms are still poorly described and modeled for this type of very complex matrices. This thesis investigates potential for the mobilization of major and trace metals elements of various contaminated complex matrices, including an urban infiltration basin sediment and two carbonated and non-carbonated mining waste (for the study of contaminated acid mining drainage and contaminated neutral drainage). Besides, pure minerals were used to simulate phase mixture at the laboratory and identify the crossed mechanisms involved in contaminated acid and neutral mine drainage. All these matrices were subjected to acid-base neutralization capacity tests (solids put into contact with a source of protons or alkalinity), with monitoring of the pH (buffer capacity), the conductivity and the elemental release (major and trace metal elements). Experimental data were modeled with the PHREEQC geochemical speciation software. The combination of experimental and modeling approaches, which had very rarely been developed on such complex solid matrices, allowed the identification of (i) the dissolution reactions of the constitutive phases of the polluted matrices with the sorption reactions involved in the mobilization of their major and trace metal elements, (ii) the speciation of the major and trace metal elements in these matrices and in solution in equilibrium with the solid phases. This thesis, therefore, leads to a robust, precise and replicable methodology allowing a fine characterization of liquid and solid phase speciation of metallic pollutants in contaminated matrices. This methodology constitutes a crucial basis for understanding and predicting the evolution of contaminated solids (urban sediments and mining waste) according to different management methods: decontamination, recovery, and recycling

This item is only available electronically.
The Olary Domain, Curnamona Province has significant economic importance as a target for base metal and gold exploration. A veneer of Cainozoic or younger regolith occurs over large areas of the Olary Domain, which complicates mineral exploration. The study area is located within a small catchment at the old Luxemburg Cu/Au mining site in the mid North of South Australia in the Southern area of the Olary Domain. This investigation focuses on relating physical and chemical weathering processes present between basement amphibolite, granites and gneisses and a local waterway, including parameters such as bedrock geochemistry, regolith profile interpretation, channel morphology, and landscape evolution. Mapping the extent and character of the regolith in the Luxemburg area in a detailed Regolith Landform Map was also a large feature of this study. Results from the Regolith Landform Map allow inferences on the present day surface dispersion pathways. Geochemical investigations of the regolith profile within the catchment indicate a considerable fingerprint from the underlying amphibolite, specifically shown by Fe, Ti, Ni, Cr, V and Sc values. The elemental signature of the surface regolith reflects the underlying parent regolith units. Geochemical patterns within the ephemeral channel can be related to source geology, streambed morphology and landscape position. Harker plots and grain size analysis indicate that the channel sediment is chemically immature and La/Sc plots against Ti, Zr and Th illustrate that the amphibolite body primarily controls its elemental signature. The geochemistry of the underlying moderately weathered bedrock can be seen and deciphered in an area of iron rich, relatively thin regolith. Bedrock signatures are also evident within the chemistry of bulk samples from the local ephemeral channel deposits. Recent mining activity within the area does not seem to have influenced the results of this study.

Abstract:
Agricultural land and woodland in the vicinity of urban settlements appear increasingly to represent a key element and strategic resource for addressing issues of residential quality, and hence the requalification of the urban construct. In effect, from a "vacuum" awaiting construction, the periurban agricultural territory is emerging as the yardstick for a new measurement and integration of the public policies governing urban and territorial plans and those for rural development. This book proposes a number of cues and methodological and operational elements to stimulate reflection on this new scenario. It does so through the exploration of a number of significant and innovative experiences in Italy and the rest of Europe, while at the same time also proposing an initial appraisal of the process of design and social mobilisation for the definition of the scenario for the Prato Agricultural Park.

The discussion emphasises on a Facebook fan page named under Jet Li, presumably is run by the actor to promote not only his movie but, more noticeably, his charity The One Foundation. It argues that his charity has a slogan, ‘One Foundation, One Family,’ evoking a world community in which human compassion and decency should extend to everyone, undermining the ‘Chinese’ element and bespeak a kind of ‘world’ awareness. As this chapter pursues to explain, the star presence in the cyber-network becomes a venue for the possible philanthropic mobilisation, displaying ambivalence of the notion of Chineseness.

This chapter addresses the use of referendums in federal constitutional systems. Federalism is under-theorised within constitutionalism and so the chapter also revisits federal thought in light of recent advances in constitutional theory. A particular focus today for constitutional scholars is the issue of constitutional amendment in a world of ever more elaborate constitutions. The concern with constitutional stability and the use of constitutions to promote particular values has led to innovations such as eternity clauses, unamendable constitutional provisions and the further empowerment of the judicial branch. A key question in contemporary debates is how best to reach the appropriate balance between open democratic decision-making on the one hand and constitutional entrenchment on the other. Into this mix the referendum has emerged as a potentially explosive element, raising the question of the extent to which ordinary citizens should be involved in processes of constitutional change. The chapter seeks to adapt important theoretical questions raised by direct democracy to the context of federalism. How does the existence of multiple governments and a foundational constitutional commitment to territorial and societal pluralism complicate further the issue of the demos, in particular when it is called upon to produce constitutional change through the mobilisation of ‘the people’? The chapter focuses upon situations where federalism reflects strong societal or demotic differences; here the use of the referendum has been particularly challenging. How should the referendum as a mechanism of constitutional change be accommodated within federal thought and federal practice, given the commitment of federalism to a carefully-crafted balance of power among the polity’s constituent territories?

Abstract:
This chapter presents the methodological framework of the book addressing the considerations of collecting data for analysis. The investigation of the Kurdish diaspora mobilisation in Denmark is primarily based on ethnographic fieldwork, which is described and justified in the chapter. The fieldwork was conducted primarily in Copenhagen from March 2016 to March 2019. This included participant observation at specific events in the public space as well as in community centres. It also included twenty-three semi-structured interviews with Kurdish activists, mainly core members of the two main Kurdish movements, also involving elements of life story interviews. Other sources such as documents and documentaries were also included. The chapter also discusses the ethical challenges of conducting fieldwork among Kurdish activists revolving around anonymity, accessibility, strategic encounters and positioning. The chapter concludes by outlining how the analyses of the subsequent chapters are structured.

Abstract:
In this chapter, the authors seek to analyse the manifestations of state violence in Brazil in the post-transition period following the 1964-1985 authoritarian regime. First, some of the possible causes of violence in the country are briefly discussed, highlighting elements of a structural nature and others related to the legacy of the authoritarian period. In a second section, the so-called May Crimes of 2006, are examined, in which execution, slaughter, and disappearance took place. A third section of the chapter examines the process of social mobilisation that occurred as a response to these crimes, particularly the strategy used by the families of victims to appeal to the Inter-American human rights system to seek justice after frustrated efforts for investigation and justice within the country.

Abstract:
The 15-year-long resistance to Shell’s pipeline in Rossport, Ireland became a strategic and symbolic site for resistance to neoliberalism and the petroleum industry, combining a community-based environmental justice struggle with a range of left social movements and international ecological activists. The movement faced state violence and media demonisation as well as divisions within the community, tensions between ecological and redistributive priorities and instrumentalisation by some political parties. Despite this the campaign was unusually long, forced substantial changes to state policy and contributed to anti-austerity alliance formation and popular learning processes in resisting fracking, as well as raising the political and financial cost of such projects. Its eventual defeat had more to do with the balance of forces against it than with internal difficulties. This chapter highlights the importance of sustained popular mobilisation, learning through action, counter expertise and alliance formation as key elements needed to bring about a better world.

Abstract:
The article focuses on revealing various civilisational-cultural (‘Russian order’, triune Ruthenian nation, Moscow – third Rome), geopolitical (Ukraine as an axis of European stability, a fragment of the so-called “convergence zone”, with features of a zone disorganised by conflict and internal fragmentation – crush zone, the concept of Russia – island) and intrasystemic (totalitarian tendencies) elements of the Russian narrative message towards Ukraine of the time of the second, great aggression (2022). The article refers to the notion of totalitarian political gnosis as a product of totalitarian reality that justifies social mobilisation against an acknowledged hostile target – in this case, an independent, struggling Ukraine with the possibility of sovereign choice of development path. The analysis refers to the historical approach and the paradigm of critical geopolitics, deconstructing the narrative that contributes to geopolitical perceptions and the geopolitical image of reality. To substantiate the claim of a totalitarian political gnosis conditioning the official narrative, reference was made to Vladimir Putin’s speech on February 21, 2022, constituting the decision to aggress against Ukraine.

Abstract:
Small boat crossings between Calais and Dover have become the object of political and media attention. From the summer of 2020 onwards, a large part of the British far-right field has been involved in mobilisations around this issue. It is possible to identify several types of actors: single-issue organisations, political organisations and video activists.The repertoire of action is similar to that of the Calais groups, mixing elements of the repertoire of classic social movements and of vigilantism. It should be noted that anti-migrant vigilantism, unlike in France, does not lead to violence but remains purely performative for social media audiences.These actors link the narrow issue of small boat crossings to broader themes such as the supposed threat posed by Islam to British society. The most radical activists connect the crossings to a civilisational peril that threatens the West with extinction. Most of the groups can be classified in a political space that overlaps with the radical right and civic nationalism, with the exception of a few actors who are simultaneously situated within the field of ethno-nationalism and within the extreme right wing.

Abstract:
Dynamically penetrating anchors (DPAs) are a recent type of mooring technology that have been shown to provide a cost-effective alternative to other forms of anchoring system in deep waters. This paper reports the results from a series of model tests undertaken to provide insight into the behavior of DPAs during dynamic installation and monotonic pull-out in normally consolidated clay and calcareous silt. The tests were carried out in a drum centrifuge at 200 g, varying the drop height and hence the terminal velocity. The pull-out angle at the mudline was also varied to encompass various mooring systems. This paper also reports the results from finite element (FE) analyses simulating dynamic installation of anchors. The 3D large deformation FE (LDFE) analyses were carried out using the Coupled Eulerian-Lagrangian (CEL) approach in the commercial FE package Abaqus/Explicit. A parametric study was undertaken, exploring a range of anchor geometry in terms of diameter, tip angle and number and length of fins; impact velocity and soil strength. For dynamic installation, two interesting aspects of the soil flow mechanisms were identified: (a) downward soil movement, concentrating around the advancing anchor, being reduced gradually with reducing penetration velocity and more rapidly with increasing number of fins and anchor projected area; (b) mobilisation of end bearing mechanism at the base of the anchor as well as fins, with the latter reduced significantly for shorter fins. The depth of anchor penetration increased as the drop height (and terminal velocity) increases and the soil strength decreases. For static pull-out, the mooring angle at the mudline influenced the pull-out mechanism and the capacity significantly. The anchor rotation and hence the anchor displacement required for attaining maximum capacity reduced as the angle increases.

Abstract:
The objective of this paper is to assess the impact of soil axial resistance on initiation of the buckles on sleepers. It also covers the effects of history of pressure and temperature increase on effective axial force as well as the incorporation of external pressure in the Finite Element (FE) models. This is carried out for 6″, 8″, 10″ and 12″ pipelines laying on sleepers with different heights for a range of axial soil frictions and mobilisations. Knowing the sensitivity of buckle initiation to soil parameters can help in simplifying engineering analysis by avoiding repetitive simulations for parameters with less importance. To carry out the above, a series of FE models including normal and bi-linear axial contacts between pipeline and sleeper / seabed were built in Abaqus FE package and at the point of initiation of the buckles, the effective axial force was extracted by a Python script. FE models were validated by comparison of the simulation results with analytical solutions and experimental results from published literature.

Abstract:
Abstract With approximately 70% of the world's petroleum located in poorly consolidated reservoirs, sand production is a global challenge. This paper explains a new well testing concept to optimise and maximise the production potential. This is achieved by finding the limit of topside sand production when the sand comes from the reservoir or is accumulated in the wellbore. If the sand comes from accumulation in the wellbore, it is removed by a cleanout operation (bottom-up) and measured by weight until the well stabilises on lower sand production to be confirmed coming from the reservoir. The next step will be to adjust the well flow to the acceptable sand rate (ASR) while still flowing at a rate not to accumulate sand in wellbore. This is difficult to achieve without proper sand measurement tools. A patent-pending well- testing method has been developed using Dual vessel desander solids management systems with regular well testing information. This method provides a complete picture of the sand production at the same time as the production potential of the well is discovered and realised. This is done while simultaneously reducing the effects of erosion from solids and without sand being transported to downstream process facilities. A dual vessel desander unit is installed during well testing to ensure sand protection for the downstream process facility. The system combines several data elements to measure solids production in real-time. The real-time data enables operators to tune wells individually for increased oil and gas production (Typically above the ASR production flow level). At the same time, ensuring produced solids are removed, measured and handled upstream of the process facility. The method shows several benefits; including improved guidelines for a well start-up (also often referred to as a well bean-up) to avoid sand to the surface, identifying unrealised production potential while maintaining solids below the ASR, and lowering overall sand production that enters the production separator by regularly cleaning wells with dual vessel desander systems. A case study from the North Sea is shared. An Operator utilised the method to reduce their coiled tubing cleanout operations due to continuous surveillance of sand producing wells that were brought into clean-up mode via the desander before they lost too much pressure and ceased production. ESG improvement over eight years, as the operator eliminated 20 coiled tubing clean-out operations, reducing operations cost, risks of heavy lifts, personnel mobilisations, and emissions per barrel produced.
