It begins by discussing the fundamentals of surfactants and their synthesis. It then moves on to present their applicability to a variety of situations such as gas injections, shale swelling inhibition, and acid stimulation. This book presents research in an evolving field, making it interesting to academics, postgraduate students, and experts within the field of oil and gas.

Written by a leading industry specialist, a must-have for drilling specialists, petroleum engineers, and field practitioners, this is the only book providing practical, rigorous and validated models for general annular flows, eccentric geometries, non-Newtonian fluids, yield stresses, multiphase effects, and transient motions and flow rates and includes new methods describing mudcake integrity and pore pressure for blowout assessment. Wilson C. Chin has written some of the most important and well-known books in the petroleum industry. These books, whose research was funded by the U.S. Department of Energy and several international petroleum corporations, have set very high standards. Many algorithms are used at leading oil service companies to support key drilling and well logging applications. For the first time, the physical models in these publications, founded on rigorous mathematics and numerical methods, are now available to the broader industry: students, petroleum engineers, drillers and faculty researchers. The presentations are written in easy-to-understand language, with few equations, offering simplified explanations of difficult problems and solutions which provide key insights into downhole physical phenomena through detailed tabulations and color graphics displays. Practical applications, such as cuttings transport, pressure control, mudcake integrity, formation effects in unconventional applications, and so on, are addressed in great detail, offering the most practical answers to everyday problems that the engineer encounters. The book does not stop at annular flow. In fact, the important role of mudcake growth and thickness in enabling steady flow in the annulus is considered, as is the role of (low) formation permeability in affecting mud filtration, cake growth, and fluid sealing at the sandface. This is the first publication addressing "the big picture," a "first" drawn from the author's related research in multiple disciplines such as drilling rheology, formation testing and reservoir simulation. A must-have for any petroleum engineer, petroleum professional, or student, this book is truly a groundbreaking volume that is sure to set new standards.

With extraction out of depleted wells more important than ever, this new and developing technology is literally changing drilling engineering for future generations. Never before published in book form, these cutting-edge technologies and the processes that surround them are explained in easy-tounderstand language, complete with worked examples, problems and solutions. This volume is invaluable as a textbook for both the engineering student and the veteran engineer who needs to keep up with changing technology.

"Hole cleaning efficiency is an important factor of consideration in the successful evaluation of any drilling operation. This is dependent on the ability of the drilling fluid to effectively remove cuttings from the bottom hole to the surface, which are affected by changes in the drilling fluid properties such as the density, pipe eccentricity, well bore geometry, well bore interactions with the external environment in the form of gas-cutting etc. This work examines the sources and effects of entrained gas on drilling fluid, borehole and hydraulic parameters and their respective impact on hole cleaning. A generalized mathematical equation was derived to predict the hole cleaning efficiency of low-viscosity non-dispersed mud systems at different rates of gas entrainment. Additionally, the total pump operating cost was investigated from the knowledge of the optimum horsepower output of the pump. A cost comparison was made between the Hydraulic Horsepower and Jet Impact Force methods of optimized drilling. From the analysis it was observed that entrained gas negatively impacts hole cleaning in comparison to a gas free system. Jet Impact Force was found to be a better tool for determining the pump operating cost and estimating the hole cleaning performance using the Carrying Capacity Index"--Leaf iii.
