Utility
Reservoir Performance System
14 Apr 22
A method can include generating an initial number of simulation models of an environment, where each of the initial number of simulation models includes a corresponding input set of values for parameters; generating an additional number of simulation models of the environment, where each of the additional number of simulation models includes a corresponding input set of values for the parameters; performing simulations of physical phenomena using each of the initial number of simulation models and each of the additional number of simulation models, where each of the simulations generates a corresponding indexed output set of values; determining a series of indexed metrics using the indexed output sets; and, based on the series of indexed metrics, deciding to output the initial number of simulation models and the additional number of simulation models as an ensemble statistically representative of the environment or to generate one or more additional simulation models.

Utility
Reservoir simulations with fracture networks
5 Apr 22
Systems and methods are described for performing a reservoir simulation for a subterranean formation with a fracture network by receiving data representing the subterranean formation, obtaining a matrix grid based on the data, where the matrix grid includes matrix grid control volumes, generating a fracture network based on the data, identifying a location of a fracture-fracture intersection within the fracture network, discretizing the fracture network into fracture network control volumes, where the fracture network is discretized independently of the matrix grid, identifying a location of a matrix-fracture intersection between the matrix grid control volumes and fracture network control volumes, calculating a transmissibility for the fracture-fracture intersection and the matrix-fracture intersection, and performing the reservoir simulation based on the transmissibility for the fracture-fracture intersection and the matrix-fracture intersection.
