Geomechanics of oil and gas wells / Геомеханика нефтяных и газовых скважин

This book presents an integrated approach to the study of geomechanical processes occurring in oil- and gas-bearing formations during their development. It includes: the choice of a model that takes into account the basic properties of rocks; experimental finding of model parameters; and numerical modeling as well as direct physical modeling of deformation and filtration processes in reservoir and host rocks. The main features of the behavior of rocks are taken into account, such as anisotropy of the mechanical properties of rocks during elastoplastic deformation, dependence of permeability on the total stress tensor, contribution of the filtration flow to the stress state of the formation, and influence of not only tangential but also normal stresses on the transition to inelastic deformation. It is shown how the presented approach allows solving practical problems of increasing the productivity of wells, oil recovery, and ensuring the stability of wellbores.

This book is intended for specialists-geomechanics working primarily in the oil and gas sector, teachers, graduate students, and students of oil universities and faculty, as well as for all those who are interested in scientific and technological development and meeting the enormous needs of mankind in raw materials and energy
