Available in PDF, EPUB and Kindle. Book excerpt: This book aims at presenting, describing, and summarizing the latest advances in polymer flooding regarding the chemical synthesis of the EOR agents and the numerical simulation of compositional models in porous media, including a description of the possible applications of nanotechnology acting as a booster of traditional chemical EOR processes. A large part of the world economy depends nowadays on non-renewable energy sources, most of them of fossil origin. Though the search for and the development of newer, greener, and more sustainable sources have been going on for the last decades, humanity is still fossil-fuel dependent. Primary and secondary oil recovery techniques merely produce up to a half of the Original Oil In Place. Enhanced Oil Recovery (EOR) processes are aimed at further increasing this value. Among these, chemical EOR techniques (including polymer flooding) present a great potential in low- and medium-viscosity oilfields. • Describes recent advances in chemical enhanced oil recovery. • Contains detailed description of polymer flooding and nanotechnology as promising boosting tools for EOR. • Includes both experimental and theoretical studies.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carefully designed chemical formulas are often applied in the enhanced oil recovery (EOR) process. Understanding the molecular distribution and working mechanism of each component can provide theoretical guidance in designing chemical formulas with desired functionalities. In this dissertation, we employ the molecular dynamics (MD) simulation to study the atomic distribution as well as the working mechanism of the amphiphilic chemical additives (surfactant, co-surfactant) applied in the petroleum industry, especially during the chemical flooding and gas injection process. In chemical flooding, surfactant formulas are injected into the reservoir to reduce the interfacial tension (IFT) between oil and brine. The injected surfactant should be stable and effective under reservoir conditions, generally associated with high-pressure high-temperature, and formation water (omnipresent in the reservoir, contains various salt ions with its salinity can be up to 35 wt.%). We first explore the effect of ion valency and concentration on sodium dodecyl sulfate (SDS) surfactant arrangement and efficiency. Two different cations (Na+ and Ca2+) with a wide range of ion concentrations (up to 3.96 M) are employed to simulate reservoir conditions. We demonstrate that ion valency has a significant effect on molecular configurations. Ca2+ ions can form unique pentagon-like SDS-Ca2+ complexes through SDS-Ca2+-SDS cation bridging. Monovalent Na+ can also generate SDS-Na+-SDS cation bridgings, while their concentration is much lower than that of SDS-Ca2+-SDS. The non-ionic (propanol) and cationic [cetrimonium bromide (CTAB)] surfactants with a wide range of concentrations are introduced to the primary SDS formula, to study the effect of chemical additives. We find that CTAB can disaggregate the cation bridging when their concentration is above a certain threshold. The cation bridging density is maintained at a low level when the sum of surfactants and cosurfactant interface charges is neutral or positive. On the other hand, propanol barely disaggregates the cation bridging. Both propanol and CTAB can further decrease the oil-brine IFT while having different efficacies. More rapid IFT decrement is observed when cation bridging is disaggregated. Propanol, as a cosurfactant, can be transported through oil and brine phases; such a dislocation of propanol in the system is a dynamic process. In the meantime, the introduction of propanol does not always increase the local fluidity of surfactants at the interface. A local maximum fluidity was observed when the SDSs are more perpendicular to the interface. These works should guide surfactant formula design in the chemical flooding process. Alcohol blending is often employed in the super critical CO2 (scCO2) gas injection. Ethanol can increase the sodium bis(2-Ethylhexyl) sulfosuccinate (AOT) solubility in scCO2 during the gas injection, while their working mechanism is not well established yet. Spontaneous aggregation processes in two systems (one consists of AOT and scCO2; the other consists of AOT, scCO2, and 10 wt.% ethanol) are conducted under a typical tight oil reservoir condition (333 K and 200 bar) to investigate the working mechanism of ethanol. After 600-ns runs, the AOT molecules aggregate together and form rod-like reversed micelles (RMs) in the System without ethanol, while forming several small sphere-like RMs by introducing the ethanol to the system. We propose that the ethanol molecules can better solvate and surround Na+ ions, preventing the further aggregation of AOT clusters. Other than increasing surfactant solubility, as an amphiphilic molecule, alcohols can also distribute at the interface region and further affect the water/scCO2 (foam interface) interfacial properties. Alcohols with varying tail lengths (C2OH-C16OH) under a wide range of concentrations are introduced to water/AOT/scCO2 interface systems to study their effects. We demonstrate that alcohol can distribute in water, interface region, and scCO2 phases, and their participation in phases is affected by the alcohol tail length. Alcohols' tail length has a negligible effect on alcohol distribution at the interface when their concentration in the scCO2 phase is fixed. On the other hand, alcohol concentration in the water phase increase as tail length decrease. The ability in decreasing IFT is similar for different tail length alcohols when alcohol concentration is relatively low (before reaching the inflection point). However, the lowest available IFT (inflection point) increases as alcohol chain length increases. The mean-squared displacement (MSD) of AOT decreases as alcohol concentration increases, and such a decrement trend is more significant in systems with long-chain alcohols. These works should provide important insights into designing chemical formulas for gas injection.

This book was released on 2020-07-18 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selection of the optimal recovery method is significantly influenced by economic issues in today’s oil and gas markets. Consequently, the development of cost-effective technologies, which bring maximum oil recovery, is the main interest in today’s petroleum research communities. Theory and Practice in Microbial Enhanced Oil Recovery provides the fundamentals, latest research and creditable field applications. Microbial Enhanced Oil Recovery (MEOR) is potentially a low-priced and eco-friendly technique in which different microorganisms and their metabolic products are implemented to recover the remaining oil in the reservoir. Despite drastic advantages of MEOR technology, it is still not fully supported in the industry due to lack of knowledge on microbial activities and their complexity of the process. While some selected strategies have demonstrated the feasibility to be used on a mass scale through both lab and field trials, more research remains to implement MEOR into more oil industry practices. This reference delivers comprehensive descriptions on the fundamentals including basic theories on geomicrobiology, experiments and modeling, as well as current tested field applications. Theory and Practice in Microbial Enhanced Oil Recovery gives engineers and researchers the tool needed to stay up to date on this evolving and more sustainable technology.

Download or read book Microbial Enhancement of Oil Recovery Recent Advances written by E.C. Donaldson and published by Elsevier. This book was released on 1991-04-03 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: This conference was instituted to examine field activities in Microbial Enhancement of Oil Recovery. The U.S. Department of Energy has sponsored several field projects and the details from some of these were presented, as well as a few from industry. The balance of the program was concerned with new developments in research. Today's oil production technology leaves one third to one half of the original oil in place in the reservoir at abandonment of secondary recovery (waterflooding). This leaves a very large target for microbial enhanced oil recovery which was shown by the research papers of this conference to be capable of producing up to 50% of the residual oil. The field trials show that the normal projected oil production decline curve can be reversed, or leveled off by microbial enhancement of oil recovery. This conference has shown that a variety of applications are possible to correct oilfield problems as well as to enhance oil recovery. Among these is the suppression of hydrogen sulfide production which alone is a tremendous advance because of the large quantity of sour oil production. If hydrogen sulfide production can be curtailed it would increase the value of the produced oil, decrease it toxicity, and largely decrease it corrosiveness. All of these would be welcome both in the field and at the petroleum refinery where special precautions must be taken to process sour crude oil. Another very important discovery is the ability of certain bacteria to eliminate paraffin deposition around the producing well and in the tubulars. This is a welcome improvement for many producers who have considerable difficulty in controlling paraffin deposition.

This book was released on 2016 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research presents an improved simulator to predict the enhanced oil recovery after applying microbial enhanced oil recovery (MEOR) technique and the onset of reservoir souring in sea-water injected reservoirs. The model is developed to study the effect of temperature, salinity, and pH on the growth of bacteria which are responsible for producing in-situ bioproducts in MEOR and causing microbial reservoir souring. The effects of environmental factors (i.e., pH, salinity, and temperature) are implemented into a four-phase chemical flooding reservoir simulator (UTCHEM). In the MEOR process, nutrients and natural bacteria are injected into a reservoir and both indigenous and injected microorganisms are able to react and then generate bioproducts based on in-situ reactions. In this study, we considered three different mechanisms proposed for MEOR: biosurfactant-dominated MEOR, biopolymer-dominated MEOR, and biomass-dominated MEOR. Results show that in-situ bioproduct generation rates can be thoroughly modeled based on environmental factors. Simulation results show 10-15% incremental oil recovery using in-situ biosurfactant compared to waterflooding, biopolymer can increase the oil recovery by 3%, and biomass can contribute to oil production by increasing the recovery by 6%. The simulation results show that nutrient concentration, salinity, and temperature are the most significant parameters influencing oil recovery, whereas pH has an insignificant effect. Reservoir souring is a phenomenon that occurs because of in-situ biodegradation reactions and is modeled in the present study. Sulfate-reducing bacteria (SRB) can convert sulfate ions into hydrogen sulfide by oxidizing a carbon source. This phenomenon is called reservoir souring when it occurs in water-flooded reservoirs. The generated H2S content affects the properties of rocks, reduces the value of produced hydrocarbon, causes corrosion in production facilities, and has health and safety issues. Because of the severity of the problem, several attempts have been made to model and predict the onset of souring. However, there are high uncertainties because of many inestimable and uncertain parameters (e.g., biodegradation parameters, sulfate concentration, reservoir pH, salinity, and temperature). Therefore, the capability of UTCHEM for calculating the maximum growth rate in terms of temperature, salinity, and pH helped us to show the environmental effect on the process. We also investigated the effect of maximum growth rate and available sulfate on the biodegradation process that leads to reservoir souring. In summary, our results show that the microbial reservoir souring process can be modeled based on environmental factors. More importantly, the results show the high sensitivity of the process to different parameters.
