Abstract: A computer simulation system is configured to display to a user a graphical user interface to allow the user to import experimental test data, identify a material model that includes one or more parameters to be calibrated during a material model calibration process, perform an iterative optimization process to calibrate the material model, the iterative optimization process uses an optimization algorithm that enforces a constraint based on Drucker's stability criterion across one or more predetermined strain ranges to generate a calibrated material model, assign the calibrated material model to a component of a simulation model based on input from the user, a real-world equivalent of the component being made of the physical material, and perform a simulation that includes the component, the simulation using the stable material model and stable set of parameters to simulate response of the real-world equivalent during the simulation.

Abstract: A computer method, apparatus and system simulate hydraulic fracturing. The computer system/method models a wellbore of an injection well. The wellbore model includes a hydraulic drill pipe element in a borehole and related fluid flow in the borehole. The borehole workflow is modeled in a subject rock formation. A simulator operatively coupled to the model obtains pressure values from the modeled borehole workflow and modeled wellbore. The simulator automatically converts pore pressure from the modeled borehole into a mechanical pressure load on the subject rock formation. The mechanical pressure as hydrostatic pressure is automatically applied to the surface of the rock formation affected by the borehole and responsively defines one or more pressure induced fractures. A 2D or 3D graphical representation of the pressure induced fractures in the rock formation are displayed on output.
