摘要: A method for determining drilling fluid density stabilizing a wellbore including obtaining shale cuttings from wellbore. In one embodiment of according to this invention, are obtained and their index properties, but not limited surface area, is measured; mean effective stress around the calculated using geostatic overburden in situ stress, field pore pressure, total wellbore; strength determined correlation between strength; strength. Methods strengths, elastic pressures, formation stresses low permeability rocks.
