SOSAT 0.7.1

State of stress analysis tool

SOSAT

The State of Stress Analysis Tool (SOSAT) is a Python package that helps analyze the state of stress in the subsurface using various types of commonly available characterization data such as well logs, well test data such as leakoff and minifrac tests, regional geologic information, and constraints on the state of stress imposed by the existence of faults and fractures with limited frictional shear strength. It employs a Bayesian approach to integrate these data into a probability density function for the principal stress components.
