  • Estimation of depletion or injection induced reservoir stresses using time-lapse sonic data in cased holes
    Patent number: 9176250
    Abstract: An apparatus and a method for recovering hydrocarbons from a subterranean formation including collecting baseline and subsequent sonic data. Either open or cased hole Stoneley and cross dipole dispersions are calculated using the baseline and subsequent sonic data, the minimum and maximum horizontal stress magnitudes are calculated using the calculating dispersions, a pressure is calculated and hydrocarbons are recovered.
    Type: Grant
