Reissue
Faulted geological structures having unconformities
25 Apr 23
A method can include providing a mesh of a geologic environment that includes conformable sequences and an unconformity; interpolating an implicit function defined with respect to the mesh to provide values for the implicit function; and identifying an iso-surface based on a portion of the values where the iso-surface represents the unconformity as residing between two of the conformable sequences.

Utility
Reservoir performance system
25 Apr 23
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.
