Methods and systems for constructing and using a subterranean geomechanics model spanning local to zonal scale in complex geological environments

A system for generating a subterranean geomechanical model, comprising:

• a local central processing unit in communication with an input device, wherein the input device comprises at least one of a keyboard, a mouse, and a sensor;
• a display device in communication with the local central processing unit and configured to display a generated model to a user;
• an interface in communication with the local central processing unit and configured to communicate with a remote processor and associated database;
• a memory unit in communication with the local central processing unit, the memory unit containing an operating system, a geomechanical model generation agent, and an operational parameters determination agent;
• a calculating module configured to calculate a pore pressure field, a stress field, a geomechanics property field, and a geological structure field from a geological concept model using information or data received from a user or a well database;
• an interpolating module configured to geostatistically interpolate scalars, vectors, and tensors from the calculated pore pressure field, the stress field, the geomechanics property field, and the geological structure field;
• and
• a constructing module configured to construct a geostatistical geomechanical model of the geological environment from combined results from the calculated pore pressure field, the stress field, the geomechanics property field, and the geological structure field and the geostatistically interpolated scalars, vectors, and tensors.
