DOWNHOLE MODELING USING INVERTED PRESSURE AND REGIONAL STRESS

摘要

Systems and methods for predicting a stress attribute of a subsurface earth volume. One or more linearly independent far field stress models and one or more discontinuity pressure models may be simulated for the subsurface earth volume to generate stress values, strain values, displacement values, or a combination thereof for data points in the subsurface earth volume. A processor may be used to compute a superposition of the one or more linearly independent far field stress models and the one or more discontinuity pressure models. The stress attribute of the subsurface earth volume may be predicted, based on the computed stress values, strain values, displacement values, or the combination thereof.

1. A method for predicting a stress attribute of a subsurface earth volume, comprising:
simulating one or more linearly independent far field stress models and one or more discontinuity pressure models for the subsurface earth volume to generate stress values, strain values, displacement values, or a combination thereof for data points in the subsurface earth volume; computing, using a processor, a superposition of the one or more linearly independent far field stress models and the one or more discontinuity pressure models; and predicting the stress attribute of the subsurface earth volume, based on the computed stress values, strain values, displacement values, or the combination thereof.
