  • Developing a book of any magnitude requires time away from family and friends, so as we finish this one, we must confess that despite the obvious intellectual and personal satisfactions we enjoyed while writing this book, it was not always a pleasant experience. The book’s contents are for the most part the result of scribbling on napkins over numerous macchiati and espressos away from the office at different posts over the years. As researchers and consultants, perhaps our most creative moments arose during lengthy informal, and somewhat dreamy, discussions about enhanced oil recovery.

  • Worldwide, crude oil demand is unceasingly increasing. As a response, Enhanced Oil Recovery (EOR) processes have re‐gained interest from the research and development phases to the oilfield EOR implementation stage. This renewed interest has been also furthered by the current high oil price environment, the maturation of oilfields worldwide, and few new‐well discoveries. Concurrently, environmental concerns and public pressure related to crude oil pollution control and remediation of oilcontaminated sites are becoming greater than ever....

  • This book is intended for graduate students, researchers, and reservoir engineers who want to understand the mathematical description of the chromatographic mechanisms that are the basis for gas injection processes for enhanced oil recovery. Readers familiar with the calculus of partial derivatives and properties of matrices (including eigenvalues and eigenvectors) should have no trouble following the mathematical development of the material presented.

  • I am enormously grateful to all of authors who have contributed to this volume on gas– liquid foam. One of the great pleasures of working with such accomplished scientists and engineers from industry and academia is that everybody has known the level at which to pitch their contributions. Special thanks are due to Laurie Schramm who, along with co-authors, has contributed two chapters on foams in enhanced oil recovery and flotation of oil sands, and to Thomas Martin who endured initial confusion upon my part to produce a first class chapter on firefighting foams....

  • Starting from a derivation of the conservation equations for multicomponent multiphase flows in porous media and a discussion of convective vs. diffusive/dispersive transport, the reader is introduced to a mathematical framework, based on the method of characteristics, for solving convection-dominated transport problems.

  • CO2 injection has recently been shown to provide significant enhanced oil recovery from naturally fractured reservoirs1. Li et al. (2000) performed CO2 injection at 1750 psig on artificially-fractured cores after water flooding in a dead-oil system. Gravity drainage was suggested to be the dominant recovery mechanism in these tests, with significant tertiary oil recovery after water flooding. The authors observed that the recovery of initial oil at the start of the CO2 injection declined as the rock permeability decreased and the initial water saturation increased....

  • Measurement of efficiency started with Farrell (1957) who, following Debreu (1951) and Koopmas (1951), proposed a division of efficiency into two components: technical efficiency, which represents a firm’s ability to produce a maximum level of output from a given level of inputs, and allocative efficiency, which is the ability of a firm to use inputs in optimal proportions, given their respective prices and available technology. The combination of these two measures yields the level of economic efficiency.

  • The causes and consequences of the Third World debt crisis have been analyzed by scholars for more than a decade. 3 Its origin lay partly in the international expansion of U.S. banking organizations during the 1950s and 1960s in conjunction with the rapid growth in the world economy, including the LDCs. For example, for more than a decade before oil prices quadrupled in 1973–74, the growth rate in the real domestic product of the LDCs av- eraged about 6 percent annually. For the remainder of the 1970s, the growth rate slowed but averaged a respectable 4 to 5 percent.
