This problem is getting more actual with time as there is observed a clear tendency of an increment of recoverable hydrocarbon reserves due to the predominant discovery of oil reserves in reservoirs of complex composition and structure. The development of such reservoirs by a traditional method (natural drives, water-flooding) is frequently not very efficient. The alternative is application of active recovery methods (RM), in other words, enhanced oil recovery methods (EORM). Nowadays over two tens of stimulation methods as well as based on them tens of injection technologies of various working agents into the formation have been developed and used. The recoverable reserves of natural hydrocarbons considerably increase when the most suitable and efficient EORM for each specific formation are used. Recovery methods are highly technological methods as compared with pool development by natural (depletion) drives and water-flooding. The selection of the proper recovery methods for natural hydrocarbon reservoir is to increase recoverable reserves (thus, to incremental oil recovery) and to decrease technological and financial risk in development. The textbook consists of an introduction, six parts, conclusion and an appendix. Pan 1 is devoted to a brief description of the current status and the prospects lor application of recovery methods. Part II gives the description of the most developed and effective oil recovery methods. The presented classes of methods include hydro-dynamic, thermal, physic-chemical, gas and microbiological ones. Within each class the mechanisms of oil displacement characteristic of the basic recovery methods are described m detail. Part III is concerned with the description of the main applicability criteria The applicability criteria consist of the following geology-physical parameters, rock, reservoir, formation oil, water, gas and other agents, petrographo- mineralogical rock composition Part IV covers the aspects of technological and economic efficiency and application of the main recovery methods based on the data obtained from experimental - industrial tests and commercial realization of these methods. Part V is dedicated to the description of the original methods of applicability estimation of recovery methods for real geological formations. This method includes expert data and a fuzzy set theory. A scientific research - methodological experience which served as a basis for compiling the present textbook has been mainly gained within the activities in the Russian State University of Oil and Gas named after Gubkin and the Oil and Gas Research Institute (OGRl) of the Russian Academy of Sciences. The authors acknowledgements express their thanks for attention, assistance and recommendations in compiling the given textbook to: Prof Sh.K. Gimatudinov, Prof. l.P. Zhabrev, Prof. Y.P. Zheltov, Prof M. M. Ivanova, Prof. I.T. Mischenko, Dr. I. A. Ponomareva, Dr. S.Y. Shalyt, Dr. R.R. Ibatullin, Dr. O.A. Chernikov. The authors are very grateful to translator senior lecturer Voevodina L. M. and E. D. Eliseenko who has spent many days and much energy on computing the present textbook.
