A calculation method of the reservoir Biot coefficient based on the Griffith criterion and the equivalent inclusion theory

Objective  The Biot coefficient is defined as the ratio of the change in pore volume to the change in total rock volume, reflecting how efficiently pore pressure offsets externally the applied total stress under loading conditions. As a key parameter in poroelastic theory, the Biot coefficient links...
