Eléments de mécanique des roches en ingénierie de réservoir
Institut Français du Pétrole, Rueil-Malmaison
This document describes the elements of rocks mechanics which are useful to reservoir specialists. In a first time, the poromechanics is presented; this science enables us to relate the distortions of the rock to pressure variations, and by this way to the flow equations. The notion of effective strain is clearly expressed and measures taken by laboratories are introduced. The consequences at the production level ("compressibility" notion) and at the environment level (surface subsidence) illustrate this notion. In a second time, the stimulation by hydraulic fracturing is presented. After a brief chronological account, the sources of modelling are defined and its implementation is presented.
