Original Abstract Submitted
Techniques for determining properties of a rock sample include performing a plurality of series of permeability measurements of a rock sample with a permeability test assembly to derive permeability values, where each series includes permeability measurements of the rock sample at a respective, constant differential pressure between a particular confining pressure and a particular pore pressure; for each series of the plurality of series, performing a curve fit operation to determine a slope and an intercept of a curve associated with a selected Biot coefficient, the permeability values, and the particular pore pressures to generate a plurality of slope values and a plurality of intercept values; determining an effective stress coefficient of the rock sample; and determining an actual Biot coefficient of the rock sample.
