Book Description
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.

Book Description
As major fractions of oil are left unexploited in reservoirs, novel enhanced oil recovery (EOR) methods are needed to recover larger portions of the fluid. Nanofluids have been reported to impact multi-phase flow behavior by various means. Nonetheless, the significance of some of the proposed effects is under debate, and the fundamental pore-scale mechanisms responsible for nanofluid-assisted EOR remain unexplained. In this work, we present the results of a multi-scale experimental study designed to develop a significantly improved understanding of the nanofluid-assisted EOR scheme. We first developed a stability assessment protocol to test the stability of, in total, eighteen nanofluids. Subsequently, the effects of stable nanofluids on interfacial properties were carefully characterized. Moreover, in order to probe the mechanisms of nanofluids at the pore scale, a miniature core-flooding apparatus, coupled with a high-resolution X-ray micro-CT scanner, was used to conduct experiments on rock samples. Oil production performance by spontaneous imbibition of both SiOx- and Al2O3-based nanofluids were tested in aged sandstone and dolomite samples. Furthermore, the effects of SiOx-based nanofluids on wettability were carefully evaluated by performing a pore-scale core-flooding experiment on oil-wet Berea sandstone samples at high-pressure and high-temperature conditions. This study reveals that wettability reversal is the primary factor responsible for the observed recovery enhancement when the selected nanofluids are introduced. While the effect of IFT reduction by nanofluids, which has been reported in some studies as a controlling factor, is less significant. However, we observed that the inclusion of surfactant in nanofluids could result in even higher oil recovery by triggering a synergistic effect through simultaneous wettability reversal and IFT reduction. By analyzing the fluid occupancy maps on a pore-by-pore basis, we observed that wettability reversal enabled the invasion of the displacing fluid into small pores by producing an imbibition flow process; while IFT reduction helped the displacing fluid to invade into pores that remained oil-wet. The combined effect of the former and the later phenomena produced the above-mentioned synergistic effect and generated superior oil recovery performance.

Book Description
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.

Book Description
Crude oil development and production in U.S. oil reservoirs can include up to three distinct phases: primary, secondary, and tertiary (or enhanced) recovery. During primary recovery, the natural pressure of the reservoir or gravity drive oil into the wellbore, combined with artificial lift techniques (such as pumps) which bring the oil to the surface. But only about 10 percent of a reservoir's original oil in place is typically produced during primary recovery. Secondary recovery techniques to the field's productive life generally by injecting water or gas to displace oil and drive it to a production wellbore, resulting in the recovery of 20 to 40 percent of the original oil in place. In the past two decades, major oil companies and research organizations have conducted extensive theoretical and laboratory EOR (enhanced oil recovery) researches, to include validating pilot and field trials relevant to much needed domestic commercial application, while western countries had terminated such endeavours almost completely due to low oil prices. In recent years, oil demand has soared and now these operations have become more desirable. This book is about the recent developments in the area as well as the technology for enhancing oil recovery. The book provides important case studies related to over one hundred EOR pilot and field applications in a variety of oil fields. These case studies focus on practical problems, underlying theoretical and modelling methods, operational parameters (e.g., injected chemical concentration, slug sizes, flooding schemes and well spacing), solutions and sensitivity studies, and performance optimization strategies. The book strikes an ideal balance between theory and practice, and would be invaluable to academicians and oil company practitioners alike. - Updated chemical EOR fundamentals providing clear picture of fundamental concepts - Practical cases with problems and solutions providing practical analogues and experiences - Actual data regarding ranges of operation parameters providing initial design parameters - Step-by-step calculation examples providing practical engineers with convenient procedures
