Abstract
Predicting downhole acoustic tool responses due to stress-induced anisotropy by performing at least the following: receiving a plurality of input data corresponding to at least one well site comprising a wellbore; constructing a three-dimensional geomechanical model based at least in part on the input data; creating at least one near field versus far field stress distribution that corresponds to the wellbore from the three-dimensional geomechanical model; creating, at least one near wellbore versus far-field velocity distribution using the at least one near field versus far field stress distribution; comparing the downhole acoustic tool response property that indicates a downhole acoustic tool's penetration depth for a subsurface geological formation with the near wellbore velocity fields; and flagging, where the downhole acoustic tool response property stays within the near-wellbore velocity field.
