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

An in-depth study of the fundamental aspects of enhanced oil recovery (EOR), this book brings together detailed analyses of proven techniques. It begins with the current theories of the origin of oil and ends with a treatise on waterflooding which is the basis of the majority of EOR processes. Two and three-phase relative permeability relationships are discussed since they form the basis for fluid flow processes in porous media. The advent of EOR has increased the need for a better understanding of three-phase flow because this has become an integral part of carbon dioxide and steam injection, yet is an area of experimental study that has been seriously neglected. The book gives a complete review and theoretical analysis of two- and three-phase fluid flow, plus a basic introduction to single-well pressure transient testing which is essential to the evaluation of volume, intrinsic reservoir pressure, reservoir discontinuities, in situ permeability and many other data required for complete reservoir evaluation. A discussion of oilfield waters is followed closely by the chemical and physical properties of employing various current EOR techniques. The book will interest a wide range of readers. Teachers of petroleum engineering will find it a ready reference to basic requirements for implementation of various EOR processes. Petroleum engineering researchers can use it to review the current state-of-the-art of the basic premise of EOR and find in it the necessary background analyses for projection of future research. The field-oriented, practical petroleum engineer will discover it to be a reliable reference to criteria for pre-EOR reservoir analysis.

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. Covers fundamental screening criteria and theories selective plugging and mobility control mechanisms Describes the basic effects on environmental parameters and the mechanics of simulation, including microbial growth kinetics Applies up to date practical applications proven in both the lab and the field

This book offers practical concepts of EOR processes and summarizes the fundamentals of bioremediation of oil-contaminated sites. The first section presents a simplified description of EOR processes to boost the recovery of oil or to displace and produce the significant amounts of oil left behind in the reservoir during or after the course of any primary and secondary recovery process; it highlights the emerging EOR technological trends and the areas that need research and development; while the second section focuses on the use of biotechnology to remediate the inevitable environmental footprint of crude oil production; such is the case of accidental oil spills in marine, river, and land environments. The readers will gain useful and practical insights in these fields.
