Abstract: A method for predicting a total minimum horizontal stress (?h) and a total maximum horizontal stress (?H) 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 (?h) and a predicted total maximum horizontal stress (?H).

Abstract: The present disclosure describes methods and systems to enhance subsurface models of fractured reservoirs. In particular, the methods and systems described herein incorporate the effects of “dynamic” compressible fractures and, thus, can improve predictions of fractured reservoir performance over time. The methods and systems may utilize predictive algorithms for mechanical and hydraulic stiffness properties of the fracture network that are based at least in part on a database of measurements derived from single fractures.
