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. 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).

Book Description
Provides an easy-to-read introduction to the area of polymer flooding to improve oil production The production and utilization of oil has transformed our world. However, dwindling reserves are forcing industry to manage resources more efficiently, while searching for alternative fuel sources that are sustainable and environmentally friendly. Polymer flooding is an enhanced oil recovery technique that improves sweep, reduces water production, and improves recovery in geological reservoirs. This book summarizes the key factors associated with polymers and polymer flooding—from the selection of the type of polymer through characterization techniques, to field design and implementation—and discusses the main issues to consider when deploying this technology to improve oil recovery from mature reservoirs. Essentials of Polymer Flooding Technique introduces the area of polymer flooding at a basic level for those new to petroleum production. It describes how polymers are used to improve efficiency of “chemical” floods (involving surfactants and alkaline solutions). The book also offers a concise view of several key polymer-flooding topics that can’t be found elsewhere. These are in the areas of pilot project design, field project engineering (water quality, oxygen removal, polymer dissolution equipment, filtration, pumps and other equipment), produced water treatment, economics, and some of the important field case histories that appear in the last section. Provides an easy to read introduction to polymer flooding to improve oil production whilst presenting the underlying mechanisms Employs “In A Nutshell” key point summaries at the end of each chapter Includes important field case studies to aid researchers in addressing time- and financial-consumption in dealing with this issue Discusses field engineering strategies appropriate for professionals working in field operation projects Essentials of Polymer Flooding Technique is an enlightening book that will be of great interest to petroleum engineers, reservoir engineers, geoscientists, managers in petroleum industry, students in the petroleum industry, and researchers in chemical enhanced oil recovery methods.

Book Description
As the world energy demand increases, and the discovery of new conventional reservoirs diminishes, the need of using enhanced oil recovery (EOR) methods, such as chemical flooding, grows. A widely used type of chemical EOR is surfactant-polymer flooding (SP). In SP flooding, a surfactant reduces the interfacial tension between oil and water to ultra low values, allowing residual oil to be mobilized and recovered. On the other hand, polymer increases the viscosity of the SP slug, thus providing better sweep efficiency than waterflooding. This EOR method shows promising results in clastic formations. Although SP flooding works well in sandstone reservoirs, it faces major drawbacks when applied in high-temperature, high-salinity carbonate formations. Such harsh environment leads to both surfactant and polymer degradation. Moreover, because of the positive charge of carbonate surfaces and the large concentration of divalent cations, large surfactant retention occurs. Here we present the performance of a novel SP formulation that achieves ultra-low interfacial tension between oil and water at injected brine salinity of 57,000 ppm, with lower surfactant retention than current retention values in carbonates. We conducted four core-flooding experiments in Indiana limestone cores at 100°C to evaluate the performance of the SP formulation in recovering residual oil. The formulation consists of carboxylates, internal olefin sulfonates and lauryl betaine surfactants. A mixture of dead oil and 20 wt.% toluene was used to represent the live oil at ambient pressure. The first three core floods recovered 75.5%, 72% and 71% respectively. However, when 1wt% NaPA was injected before the chemical flood in the fourth experiment, 90% of the original oil-in-place was recovered, reducing the residual oil to only 4.5%. We found that the optimum SP slug size is 0.39PV at which the surfactant retention is 0.29mg/g-rock. In addition, reducing the frontal velocity to 0.5ft/day resulted in doubling the retention. The moderate surfactant retention makes SP flooding in carbonates feasible because less surfactant is needed to reach ultra-low interfacial tension. This new formulation enables application of SP flooding in high-temperature, high-salinity carbonate reservoirs, which, in return, will increase ultimate oil recovery from conventional reservoirs

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
