System and Methods for Estimating Subsurface Horizontal Principal Stresses in Anisotropic Formations
A method for predicting a total minimum horizontal stress (σh) and a total maximum horizontal stress (σH) for an anisotropic formation may comprise: measuring Young's moduli parallel ±15° and perpendicular ±15° to a transverse isotropy plane of a horizontal core sample from the anisotropic subt...

| description | A method for predicting a total minimum horizontal stress (σh) and a total maximum horizontal stress (σH) for an anisotropic formation may comprise: measuring Young's moduli parallel ±15° and perpendicular ±15° to a transverse isotropy plane of a horizontal core sample from the anisotropic subterranean formation; measuring Poisson's ratios parallel ±15° and perpendicular ±15° to the transverse isotropy plane of the horizontal core sample; inputting the measured Young's moduli and Poisson's ratios of the horizontal core sample into a 1-dimensional mechanical earth model (1-D MEM); and calculating, using the 1-D MEM, a predicted total minimum horizontal stress (σh) and a predicted total maximum horizontal stress (σH). |
