Abstract

A machine, computer program product, and method to enable scalable parallel reservoir simulations for a variety of simulation model sizes are described herein. Some embodiments of the disclosed invention include a machine, methods, and implemented software for performing parallel processing of a grid defining a reservoir or oil / gas field using a plurality of sub-domains for the reservoir simulation, a parallel process of re-ordering a local cell index for each of the plurality of cells using characteristics of the cell and location within the at least one sub-domain and a parallel process of simulating at least one production characteristic of the reservoir.

Description

technical field [0001] The present invention relates to hydrocarbon reservoir simulation, and more particularly to machines, computer program products and methods to enable scalable parallel processing of hydrocarbon reservoirs for multiple simulation model sizes. Background technique [0002] Subsurface geological bodies or formations contain multi-phase, multi-component fluids, and thus, crude oil reservoirs may contain oil, gas, water, and several constituent compounds that can be modeled to predict fluid flow from the reservoir, which also Known as reservoir simulation. Reservoir simulation models can be run before or after drilling to determine, among other things, production rates for various methods. [0003] Current reservoir modeling techniques create a numerical grid of the reservoir composed of multiple grid cells and process data in a finite volume for each grid cell. Because reservoirs can be very large and complex, with grid cells ranging from millions to ove...
