Available in PDF, EPUB and Kindle. Book excerpt: In this report, we present the results of our experimental and theoretical studies in surfactant-enhanced alkaline flooding for light oil recovery. The overall objective of this work is to develop a very cost-effective method for formulating a successful surfactant-enhanced alkaline flood by appropriately choosing mixed alkalis which form inexpensive buffers to obtain the desired pH (between 8.5 and 12. 0) for ultimate spontaneous emulsification and ultralow interfacial tension. In addition, we have (1) developed a theoretical interfacial activity model for determining equilibrium interfacial tension, (2) investigated the mechanisms for spontaneous emulsification, (3) developed a technique to monitor low water content in oil and (4) developed a technique to study water-in-oil emulsion film properties, (5) investigated the effect of surfactant on the equilibrium and transient interfacial tension, (6) investigated the kinetics of oil removal from a silica surface, and (7) developed a theoretical interfacial activity model for determining equilibrium interfacial tension, accounting for added surfactant. The results of the studies conducted during the course of this project are discussed.

This book was released on 1993 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of this project is to develop a very cost- effective method for formulating a successful surfactant-enhanced alkaline flood by appropriately choosing mixed alkalis which form inexpensive buffers to obtain the desired pH (between 8.5 and 12.0) for ultimate spontaneous emulsification and ultra-low tension. In addition, the novel concept of pH gradient design to optimize flood water conditions will be tested. Last quarter we have investigated the mechanisms responsible for spontaneous emulsification in alkali/acidic crude oil systems with and without added surfactant. We have observed that the roll cell size and formation time depend strongly on the pH and ionic strength of the alkaline solution. For a particular roll cell size, the addition of surfactant causes the cells to take longer to form, causing an interfacial resistance to mass transfer and making the interface more rigid. We have shown that interfacial turbulence is a necessary but not sufficient condition for spontaneous emulsification. Low interfacial tension is also a necessary condition. This quarter a microwave interferometric procedure was developed for the determination of low water content (0. 5 to 10 vol%) of water-in-oil macroemulsions. The apparatus operates at a frequency of 23.48 GHz in the K-band microwave region. The procedure is based on the large differences in dielectric properties between water and oil, and it utilizes the variation in phase shift as sample path length is varied. Measurements are accurate to within 0.5 vol% water.

This book was released on 1994 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of this project is to develop a very cost-effective method for formulating a successful surfactant-enhanced alkaline flood by appropriately choosing mixed alkalis which form inexpensive buffers to obtain the desired pH (between 8.5 and 12.0) for ultimate spontaneous emulsification and ultra-low tension. In addition, the novel concept of pH gradient design to optimize flood water conditions will be tested. Last quarter we investigated the phase behavior and the regions where in the middle phase occurs. The optimum phase was found to go through a maximum with pH, sodium concentration and surfactant concentration. The optimum pH is about 12.0 to 13.5, the optimum sodium concentration is about 0.513 mol/liter, and the optimum surfactant concentration is about 0.2%. The effect of surfactant type was also investigated. Petrostep B-105 was found to give the most middle phase production. This quarter, we investigated the contact angle of Long Beach oil, Adena oil, and a model oil on a solid glass surface in contact with an aqueous alkaline solution both with and without added preformed surfactant. The contact angle with Long Beach and Adena oils showed oil-wet conditions, whereas the model oil showed both oil-wet and water-wet conditions depending on the pH of the aqueous phase. The addition of surfactant to the alkaline solution resulted in making the system less oil-wet. Spreading of the oil on the glass surface was observed in all three systems investigated.

The effect of surfactant type was also investigated. Petrostep B-105 was found to give the most middle phase production. A white precipitate was observed in some two-phase samples. For a given surfactant concentration, as pH is increased, the maximum volume of middle phase shifts to higher salinities. For a given pH, as surfactant concentration is increased, the maximum volume of middle phase shifts to higher salinities.

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. About the Authors Patrizio Raffa is Assistant Professor at the University of Groningen. He focuses on design and synthesis of new polymeric materials optimized for industrial applications such as EOR, coatings and smart materials. He (co)authored about 40 articles in peer reviewed journals. Pablo Druetta works as lecturer at the University of Groningen (RUG) and as engineering consultant. He received his Ph.D. from RUG in 2018 and has been teaching at a graduate level for 15 years. His research focus lies on computational fluid dynamics (CFD).

Available in PDF, EPUB and Kindle. Book excerpt: It is with great pleasure and satisfaction that I present to the international scientific community this collection of papers presented at the symposium on Surface Phenomena in Enhanced Oil Recovery held at Stockholm, Sweden, during August 20-25, 1979. It has been an exciting and exhausting experience to edit the papers included in this volume. The proceedings cover six major areas of research related to chemical flooding processes for enhanced oil recovery, namely, 1) Fundamental aspects of the oil displacement process, 2) Micro structure of surfactant systems, 3) Emulsion rheology and oil dis placement mechanisms, 4) Wettability and oil displacement mecha nisms, 5) Adsorption, clays and chemical loss mechanisms, and 6) Polymer rheology and surfactant-polymer interactions. This book also includes two invited review papers, namely, "Research on Enhanced Oil Recovery: Past, Present and Future," and "Formation and Properties of Micelles and Microemulsions" by Professor J. J. Taber and Professor H. F. Eicke respectively. This symposium volume reflects the current state-of-art and our understanding of various surface phenomena in enhanced oil recovery processes. The participation by researchers from various countries in this symposium reflects the global interest in this area of research and the international effort to develop che science and technology of enhanced oil recovery processes.
