Повний текст джерелаPAHs are the largest, ubiquitous and carcinogenic environmental chemical groups. In a context of polluted soil remediation, today it is still a challenge to reach an effective in situ treatment. This study aims to evaluate as an alternative way the potential of a technology combining a thermal process (injection of steam) and a chemical process (co-injection of air) in the saturated zone. A first introductory experimental section considers the influence of a single steam treatment on the release of PAHs from soil matrices within the aquifer. Results prove the necessity of coupling a chemical oxidation technique with this process. If the steam front allows to recover light com- pounds, concentrations of heavier compounds in the dissolved phase are more important after the steam treatment (molar fractions of residual compounds increase). In order to study the fate of PAHs in polluted soils under medium temperature oxidation, numerous experiments in presence of soil spiked matrices were carried out in closed reactors. The catalytic potential of different mineral surfaces was investigated by studying reactivity of different PAHs. Results demonstrate that the efficiency of oxidation remains moderate. They suggest a lack of mineralization and reactions producing partly polycyclic aromatic compounds (PACs) with equivalent molecular weight as the initial contaminants. Along short term experiments (9 days), the major effect of heating is an increase in irreversible sorption of original compounds. Interestingly, this sorption mostly occurs in presence of natural organic matter and oxygen in the gas phase, suggesting a specific reactivity of the natural organic matter. In long term experiments (6 months), new oxygenated PACs were formed and remained fixed on the solid phase. Consequently, air oxidation catalyzed by minerals and natural organic matter may be a new pathway concerning PAH stabilization in soils. The steam injection technique is still considered as a costly technique. In this last part some technical solutions have been proposed, implemented and modelized. The economic aspect of some injection cases are compared, based on the results of a real field application and some general calculations regarding the costs of wells and energy. Among influential parameters, the radius of influence is a key parameter that determines the distance between each well for an optimum efficiency. The results of this study show that in some scenarios of injection (when the injection takes place in a deeper zone), a preheating phase can be an interesting option to reduce the financial costs of the technique. The main results of the thesis are compared with other steam injection studies to identify the best conditions for the technique application
Greene, John A. "An Investigation of Engineered Injection and Extraction as an in situ Remediation Technique for Uranium-Contaminated Groundwater." Thesis, University of Colorado at Boulder, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10682286.
Повний текст джерелаDuring in situ remediation of contaminated groundwater, a treatment chemical is injected into the contaminated groundwater to degrade a contaminant through chemical reaction that occurs in the subsurface. Reactions and subsequent contaminant degradation occur only where the treatment chemical contacts the contaminant long enough to complete degradation reactions. Traditional in situ groundwater remediation relies on background groundwater flow to spread an injected treatment chemical into a plume of contaminated groundwater.
Engineered Injection and Extraction (EIE), in which time-varying induced flow fields are used to actively spread the treatment chemical into the contaminant plume, has been developed to increase contact between the contaminant and treatment chemical, thereby enhancing contaminant degradation. EIE has been investigated for contaminants degrading through irreversible, bimolecular reaction with a treatment chemical, but has not been investigated for a contaminant governed by complex biogeochemical processes. Uranium fate and transport in subsurface environments is governed by adsorption, oxidation reduction, solution, and solid-phase interactions with naturally occurring solution species, microbial communities, minerals and aquifer media. Uranium primarily occurs in aqueous, mobile U(VI) complexes in the environment but can be reduced to sparingly soluble, immobile U(IV) solid-phase complexes by native dissimilatory metal reducing bacteria.
This work investigates the ability of EIE to promote subsurface delivery of an acetate-amended treatment solution throughout a plume of uranium-contaminated groundwater to promote in situ growth of native microbial communities to immobilize uranium. Simulations in this investigation are conducted using a semi-synthetic flow and reactive transport model based on physical and biogeochemical conditions from two uranium contaminated sites: the Naturita Uranium Mill Tailings Remedial Action (UMTRA) Project site in southwestern Colorado and the Old Rifle UMTRA Project site in western Colorado.

Повний текст джерелаThe method "toe-to-heel air injection" (THAITM) is a process of enhanced oil recovery, which is the integration of in-situ combustion with technological advances in drilling horizontal wells. This method uses horizontal wells as producers of oil, keeping vertical injection wells to inject air. This process has not yet been applied in Brazil, making it necessary, evaluation of these new technologies applied to local realities, therefore, this study aimed to perform a parametric study of the combustion process with in-situ oil production in horizontal wells, using a semi synthetic reservoir, with characteristics of the Brazilian Northeast basin. The simulations were performed in a commercial software "STARS" (Steam, Thermal, and Advanced Processes Reservoir Simulator), from CMG (Computer Modelling Group). The following operating parameters were analyzed: air rate, configuration of producer wells and oxygen concentration. A sensitivity study on cumulative oil (Np) was performed with the technique of experimental design, with a mixed model of two and three levels (32x22), a total of 36 runs. Also, it was done a technical economic estimative for each model of fluid. The results showed that injection rate was the most influence parameter on oil recovery, for both studied models, well arrangement depends on fluid model, and oxygen concentration favors recovery oil. The process can be profitable depends on air rate
O m?todo toe-to-heel air injection (THAITM) ? um processo de recupera??o de petr?leo avan?ado, que consiste na integra??o da combust?o in-situ com os avan?os tecnol?gicos na perfura??o de po?os horizontais. Este m?todo utiliza po?os horizontais como produtores de ?leo, mantendo po?os injetores verticais para a inje??o de ar. Este processo ainda n?o foi aplicado no Brasil, tornando necess?rio, avalia??o destas novas tecnologias aplicadas ?s realidades locais, por isso, este trabalho teve como objetivo principal realizar um estudo param?trico do processo de combust?o in-situ com produ??o de ?leo em po?os horizontais, usando um reservat?rio semi sint?tico, com caracter?sticas das encontradas no Nordeste Brasileiro. As simula??es foram realizadas em um programa comercial de processos t?rmicos, denominado STARS (Steam, Thermal, and Advanced Processes Reservoir Simulator), da empresa CMG (Computer Modelling Group). Foram realizadas an?lises dos par?metros operacionais: vaz?es de inje??o, configura??o dos po?os e concentra??o de oxig?nio. O estudo de sensibilidade dos fatores foi realizado com a t?cnica de an?lise de planejamento experimental, com uma combina??o de dois e tr?s n?veis (32x22), totalizando 36 simula??es, 18 para cada modelo, em fun??o da produ??o acumulada de ?leo (Np). Tamb?m foi realizada uma estimativa econ?mica de an?lise de custo para cada modelo de fluido. Os resultados mostraram que a configura??o de po?os e a vaz?o de inje??o foram o par?metro que apresentou maior influ?ncia no ?leo recuperado para os dois modelos de fluidos analisados, respectivamente, que a configura??o de po?os ? influenciada pelo modelo de fluido, e que um aumento da concentra??o de oxig?nio favorece a recupera??o de ?leo, no processo estudado.

Повний текст джерелаNearly 3 x 1011 m3 of medium and light oils will remain in reservoirs worldwide after conventional recovery methods have been exhausted and much of this volume would be recovered by Enhanced Oil Recovery (EOR) methods. The in-situ combustion (ISC) is an EOR method in which an oxygen-containing gas is injected into a reservoir where it reacts with the crude oil to create a high-temperature combustion front that is propagated through the reservoir. The High Pressure Air Injection (HPAI) method is a particular denomination of the air injection process applied in light oil reservoirs, for which the combustion reactions are dominant between 150 and 300?C and the generation of flue gas is the main factor to the oil displacement. A simulation model of a homogeneous reservoir was built to study, which was initially undergone to primary production, for 3 years, next by a waterflooding process for 21 more years. At this point, with the mature condition established into the reservoir, three variations of this model were selected, according to the recovery factors (RF) reached, for study the in-situ combustion (HPAI) technique. Next to this, a sensitivity analysis on the RF of characteristic operational parameters of the method was carried out: air injection rate per well, oxygen concentration into the injected gas, patterns of air injection and wells perforations configuration. This analysis, for 10 more years of production time, was performed with assistance of the central composite design. The reservoir behavior and the impacts of chemical reactions parameters and of reservoir particularities on the RF were also evaluated. An economic analysis and a study to maximize the RF of the process were also carried out. The simulation runs were performed in the simulator of thermal processes in reservoirs STARS (Steam, Thermal, and Advanced Processes Reservoir Simulator) from CMG (Computer Modelling Group). The results showed the incremental RF were small and the net present value (NPV) is affected by high initial investments to compress the air. It was noticed that the adoption of high oxygen concentration into the injected gas and of the five spot pattern tends to improve the RF, and the wells perforations configuration has more influence with the increase of the oil thickness. Simulated cases relating to the reservoir particularities showed that smaller residual oil saturations to gas lead to greater RF and the presence of heterogeneities results in important variations on the RF and on the production curves
Aproximadamente 3 x 1011 m3 de ?leos m?dios e leves restar?o nos reservat?rios ao redor do mundo ap?s a aplica??o dos m?todos convencionais de recupera??o e grande parte desse volume seria recuper?vel com o uso de m?todos especiais. A combust?o in-situ (CIS) ? um m?todo de recupera??o avan?ada de petr?leo no qual um g?s que cont?m oxig?nio ? injetado no reservat?rio onde reage com o ?leo cru para criar uma frente de combust?o de alta temperatura que se propaga pelo reservat?rio. O m?todo HPAI (High Pressure Air Injection) ? uma denomina??o particular do processo de inje??o de ar aplicado em reservat?rios de ?leos leves, onde as rea??es de combust?o s?o dominantes entre 150 e 300?C e a gera??o de flue gas ? o principal fator de deslocamento do ?leo. Um modelo de simula??o de fluxo de um reservat?rio homog?neo foi constru?do para o estudo, o qual foi inicialmente submetido ? produ??o prim?ria, por 3 anos, e em seguida, ao processo de inje??o de ?gua por mais 21 anos. Nesse ponto, com a condi??o madura estabelecida no reservat?rio, foram selecionadas tr?s varia??es desse modelo, de acordo com o fator de recupera??o (FR) obtido, para o estudo da t?cnica de combust?o in-situ (HPAI). Em seguida realizou-se uma an?lise de sensibilidade sobre o FR de par?metros operacionais pr?prios do m?todo: vaz?o de inje??o de ar por po?o, concentra??o de oxig?nio no g?s injetado, esquema de inje??o de ar e configura??o dos canhoneados dos po?os. Essa an?lise, para um per?odo adicional de at? 10 anos produ??o, foi efetuada com o aux?lio da t?cnica de planejamento composto central. O comportamento do reservat?rio e os impactos de par?metros envolvendo as rea??es qu?micas e de particularidades de reservat?rio sobre o FR tamb?m foram avaliados. Adicionalmente foram elaborados uma an?lise econ?mica e um estudo de maximiza??o do FR do processo. As simula??es foram realizadas com o simulador de processos t?rmicos em reservat?rios STARS (Steam, Thermal and Advanced Process Reservoir Simulation) da CMG (Computer Modelling Group). Os resultados mostraram que os FR incrementais foram baixos e que o valor presente l?quido (VPL) ? impactado negativamente pelos elevados investimentos iniciais para compress?o do ar. Observou-se que a ado??o de maiores concentra??es de oxig?nio no g?s injetado e do esquema de inje??o de ar tipo five spot tende a favorecer o FR, e que a configura??o dos canhoneados dos po?os apresenta influ?ncia crescente com o aumento da espessura porosa com ?leo do reservat?rio. Casos simulados referentes ?s particularidades de reservat?rio indicaram que menores satura??es residuais de ?leo ao g?s levam a FR maiores e que a exist?ncia de heterogeneidades resulta em varia??es consider?veis nos FR e nas curvas de produ??o

Apresentamos um modelo para a injeção de ar em um meio poroso que contém combustível sólido levando em conta as perdas térmicas para rocha circundante. Em trabalhos anteriores, o modelo foi simplificado e todas as sequências de ondas para a solução de problemas de Riemann foram obtidas sem levar em conta as perdas térmicas. Nesse trabalho, é feito um primeiro passo para entender o efeito das perdas de calor, que são importantes especialmente em experimentos de laboratório. Para provar a existência e unicidade da solução de ondas viajantes, os efeitos de difusão e a dependência da densidade do gás na temperatura são desconsiderados. Também são apresentadas simulações numéricas que validam os resultados obtidos, bem como simulações numéricas para um sistema mais geral que considera termos difusivos. Por fim são comparadas as soluções numéricas para ambos sistemas e um exemplo numérico com valores típicos dos parâmetros para um modelo de combustão é apresentado.
We present a model for the injection of air into an underground porous medium that contains a solid fuel. In previous works the model was simplified and all wave sequences for the Riemann problem solution were obtained without taking into account thermal losses to the surrounding rock. In that work the first step was made to understand the effect of heat losses, which are important especially in laboratory experiments. In order to prove of the existence and uniqueness of the traveling wave solution, diffusion effects and the dependence of gas density on temperature were disregarded. We will also present numerical simulations that validate the results obtained, as well as numerical simulations for a more general system that considers diffusive terms. Furthermore, we will compare the numerical solutions for both systems and a numerical example with typical values of the parameters for a combustion model is presented.

Повний текст джерелаThe current work focuses on extensive experimental approaches to identify quasi-static and fatigue damage behavior of PA66/GF30 considering various effects such as relative humidity and injection process induced microstructure. By using in situ SEM tests, it was observed that relative humidity conditions strongly impact the damage mechanisms in terms of their initiation, level and chronology. The X-ray micro-tomography analysis on fatigue loaded samples demonstrated that the damage continuously increases during fatigue loading, but the evolution occurs more significantly in the second half of the fatigue life. From the results of damage investigation under quasi-static and fatigue loading, it was established that both loading types exhibit the same damage mechanisms, with fiber/matrix interfacial debonding as the principal damage mechanisms. General damage chronologies were proposed as the damage initiates at fiber ends and more generally at locations where fibers are relatively close to each other due to the generation of local stress concentrations. Afterwards, interfacial decohesions further propagate along the fiber/matrix interface. At high relative flexural stress, matrix microcracks can develop and propagate, leading to the damage accumulation and then the final failure. The experimental findings are important to provide a physically based damage mechanisms scenarios that can be integrated into multiscale damage models. These models will contribute towards reliable predictions of damage in reinforced thermoplastics for lightweight automotive applications

"Measuring permeability vs depth in the unlined section of a wellbore using the descent of a fluid column made of two distinct fluids : inversion workflow, laboratory & in-situ tests." Thesis, Université Paris-Saclay (ComUE), 2018. http://www.theses.fr/2018SACLX086/document.
Повний текст джерелаIn wells producing water, oil, gas or geothermal energy, or in access wells to hydrocarbon storage, it is critical to evaluate the permeability of the formation as a function of depth, to improve the reservoir model, and also to identify the zones where additional investigation or special completions are especially useful.A new technique is proposed, consisting of scanning the open hole (uncased section of the wellbore) with an interface between two fluids with a large viscosity contrast. The injection rate into the formation depends on interface location and well pressure history. An inverse problem should be solved: estimate permeability as a function of depth from the evolution of flow rates with time. The wells are usually equipped with a central tube. The scanning is done by injecting a liquid in the central tube at constant wellhead pressure. Injection and withdrawal rates are measured at the wellhead; the difference between these two rates is the formation injection rate.To validate and improve this technique, we used a laboratory model mimicking a multi-layer formation, already available at LMS. We also made use of in-situ tests performed on an ultra-low permeable cap rock above an underground gas storage reservoir. In these tests, a viscous fluid contained in the open hole was displaced by a less-viscous fluid (a method called opening WTLog). The more permeable layers were correctly identified (Manivannan et al. 2017), but a quantitative estimation was challenging due to transient phenomena in the vicinity of the wellbore (near-wellbore zone). In addition, the investigation radius was small.These challenges are addressed by proposing a slightly modified test procedure and a new interpretation workflow. Laboratory tests with a modified test setup showed the advantages of the ‘closing’ method in which the well is filled with a less-viscous fluid at the start of the test. We also added a stabilization period before the injection of viscous fluid to minimize the transient effects; this period is also used to estimate the average permeability of the open hole and the effect of near-wellbore damage (skin).Then the test proper is performed (closing WTLog). The injection profile of the less-viscous fluid is computed from the wellhead flow rate history. A permeability profile is estimated from the injection profile. The permeability estimation considers a monophasic flow in each layer and the same skin value for all the formation layers. Major uncertainties in the permeability estimates are caused by formation pressures and heterogeneities in skin values; they are estimated using an analytical formula. We have verified on the laboratory setup that the estimated permeability profiles are well correlated to the permeabilities measured before the tests.An attempt was made to perform a WTLog in a 1750-m long wellbore opening in a salt formation. The first phase was successful and the average permeability was correctly assessed. However, this permeability was so small (4.0E-21 m² or 4 nD) that the gauges and the flowmeters were not accurate enough to allow a clear distinction between the permeabilities of the various parts of the open hole

Повний текст джерелаThe present work presents the development of analytical methodologies based on Sequential Injection Analysis (SIA) for determination of phosphate and silicate, nitrite and nitrate, as well as speciation Fe(II)/Fe(III) in environmental samples with emphasis for aquatic environments. All determinations were performed using molecular absorption spectrophotometry at the visible range of the spectrum as the detection technique. The determination of phosphate and silicate was based on the reaction of both anions with ammonium molybdate in acidic medium, followed by reduction of Mo(VI) to Mo(V) with ascorbic acid. The SIA procedure was developed to avoid the mutual interference of both species exploiting the complexation of the molybdate by oxalic acid. The determination of nitrite was based on the diazotation reaction with sulfanilamide and N-l naphtyl ethylenediamine dihydrochlorine (NED), while the determination of Fe(II) were based on the complexation with 1,10 phenantroline. The determination of nitrate and Fe(III) were based on the same reactions, performed after their reduction to nitrite and Fe(II) in reducing columns containing cooperized cadmium and amalgamated zinc, respectively. The stability of the analytical curves was evaluated in different working days, in which no variations greater than 5% were observed during a period of 4 consecutive days. The sequential injection analysis was exploited to regenerate the reducing columns in the time interval between two sample. The stability of the analytical curves, the easy and automatic regeneration of the reducing columns, as well as the possibility to perform sampling through tangential filtration, which permits the analysis to be performed in real time, are characteristics that show the potential application of the sequential injection systems in automatic stations for monitoring the soluble fraction of pollution indicators in natural waste waters.

Nursery age pigs (n=198) were used to evaluate the difference in the occurrence of injection site abscesses between needle-free jet injection and conventional needle-and-syringe injection systems. Pigs were fed for 21 d prior to treatment administration to acclimate the pigs to the environment of the Kansas State University Segregated Early Weaning (SEW) unit. On d 21 each pig was injected with aluminum hydroxide adjuvant in the neck and ham with needle-free jet injection (Pulse Needle-Free Systems, Lenexa, KS) and conventional needle-and-syringe injection. Needle-free and conventional needle-and-syringe injections were randomly assigned to pig side yielding a total of 396 injections per treatment with a total of 792 injections sites. Immediately prior to injection, the external surface of the injection sites were contaminated with an inoculum of Arcanobacterium pyogenes, a bacterium commonly associated with livestock abscesses. The pigs were then fed for a period of 27 or 28 d. On d 27 or d 28 the pigs were humanely euthanized and sent to the Kansas State Veterinary Diagnostics Laboratory where necropsies were performed and the injection sites harvested for histopathological evaluation. The needle-free jet injection system was associated with more injection site abscesses than the conventional needle-and-syringe injection method for both neck (P=0.0625) and ham (P=0.0313) injection sites. Twelve abscesses were found at injection sites administered via needle-free jet injection method while only 1 abscess was found with the conventional needle-and-syringe injection method. 5 abscesses were found at the neck injection sites and 8 abscesses were found at ham injection sites. There were no significant differences seen in tissue granulation resulting from reaction to the adjuvant. In summary, the implementation of needle-free jet injection systems in market hog production will be beneficial to eliminate needles and needle fragments in meat products but, when in the presence of Arcanobacterium pyogenes, it may increase the occurrence of injection site abscesses in pork carcasses that will need to be trimmed in pork processing plants. Although more abscesses were associated with needle-free jet injection, their occurrence was observed at a very low rate given that all injection sites were intentionally contaminated prior to injection.

Повний текст джерелаThe web has become a backbone of our industry and daily life. The growing popularity of web applications and services and the increasing number of critical transactions being performed, has raised security concerns. For this reason, much effort has been spent over the past decade to make web applications more secure. Despite these efforts, recent data from SANS institute estimates that up to 60% of Internet attacks target web applications and critical vulnerabilities such as cross-site scripting and SQL injection are still very common. In this thesis, we conduct two empirical studies on a large number of web applications vulnerabilities with the aim of gaining deeper insights in how input validation flaws have evolved in the past decade and how these common vulnerabilities can be prevented. Our results suggest that the complexity of the attacks have not changed significantly and that many web problems are still simple in nature. Our studies also show that most SQL injection and a significant number of cross-site scripting vulnerabilities can be prevented using straight-forward validation mechanisms based on common data types. With these empirical results as foundation, we present IPAAS which helps developers that are unaware of security issues to write more secure web applications than they otherwise would do. It includes a novel technique for preventing the exploitation of cross-site scripting and SQL injection vulnerabilities based on automated data type detection of input parameters. We show that this technique results in significant and tangible security improvements for real web applications

Повний текст джерелаStudio in modello animale della regolazione trascrizionale indotta dalla somministrazione di alcune molecole con attività immunostimolatoria. In particolare il lavoro è focalizzato sull’effetto che ha l’emulsione MF59 sull’immunità innata a livello del sito di iniezione, rispetto ad altre classi di adiuvanti. Dati riguardanti la risposta anticorpale hanno dimostrato con MF59 sia il miglior adiuvante per gli antigeni dell’influenza rispetto agli altri adiuvanti classici come alum e CpG. Per questo si è deciso di investigare, tramite analisi microarray, l’effetto di MF59, rispetto alle altre molecole, a livello di espressione genica al sito di iniezione (nel muscolo) e distalmente (nel linfonodo). È stato osservato come MF59 sia il più forte attivatore di geni codificanti per chemochine e citochine al sito di iniezione, suggerendo un suo effetto sull’immunità innata. Essendo inoltre l’emulsione anche in grado di attivare l’espressione di geni codificanti per proteine coivolte nel pathway di migrazione transendoteliale e per i recettori delle chemochine, è stato selezionato il gene Itgam, codificante per l’integrina CD11b, appunto coinvolta in tale meccanismo: lo studio di localizzazione tramite microscopia confocale di sezioni di muscolo, ha evidenziato come MF59, rispetto agli altri adiuvanti, induca un “recruitment” di cellule CD11b+ al sito di iniezione. Inoltre la regolazione dell’espressione di alcuni marcatori di superficie in cellule del linfonodo è stata confermata mediante citofluorimetria.
