Abstract
The present disclosure provides systems and methods for determining in-situ stresses based on an orthotropic rock physics model. The method may include obtaining multiple physical parameters of a rock; constructing an orthotropic rock physics model based at least in part on the multiple physical parameters; determining multiple stiffness coefficients based on the orthotropic rock physics model; and determining one or more in-situ stresses of the orthotropic rock based on the multiple stiffness coefficients.
