... as a complication that needs to be corrected for. The new interpretation method is based on the observation in geomechanical modelling that thinner, stiffer or undepleted parts of the reservoir act as stress attractors, which "arch away" overburden load from thicker, more compressible or strongly depleted parts...

...1. INTRODUCTION It is known that one of the main mechanical parameters involved in reservoir geomechanics is the compressibility of porous media. It is also well known that the rock compressibility is a function of both the in-situ stresses and the reservoir fluid pressure and that it can...

... implications of the static theory of linear poroelasticity for reservoir compaction are dis- cussed. First, the relationship between the bulk compressibility and the uniaxial compaction coefficient is re- viewed. Then, an expression is derived for the pore compressibility under uniaxial strain conditions...

... defurmation, and between stress and permeability. For example, standard reservoir simulation predicts that a low compressibility in a highly compressible reservoir will yield the same drawdown and production history as a highly compressible fluid in a low compressibility reservoir provided the total...

... was computed independently for the loading portion (B-C) and then for the unloading portion (C-D) by fitting each portion of the curve to a smooth power law. The compressibility is greater during loading (that is, during pore pressure redu;- tion accompanying production of hydrocarbons) than during unloading...
