Abstract
In the laboratory, the pore-compressibility characteristics of some limestone samples obtained from a Saudi Arabian petroleum reservoir were determined. The experimental data is presented in the form of relative porosity and hydrostatic pore-compressibility values as functions of differential pressure. Four groups of limestone samples consisting of grainstones, packstones, wackestones, and mudstones were studied. Also, Berea sandstone was tested for comparison with limestone. The results show linear negative correlations on a log-log scale between pore compressibility and differential pressure for all the tested samples. Mathematical expressions for predicting pore compressibility and porosity as functions of differential pressure are given for the tested samples. -from Authors
