Abstract: A computer-implemented method for manipulating a mesh for the discretization of a reservoir domain, the reservoir domain modeled by a geophysical model, a fluid model, or both models. The method includes the use of cells partitioning the reservoir domain wherein each cell includes a numerical mesh. The mesh of the reservoir domain is the union of the meshes located in the plurality of cells. The partitioning of the domain into a plurality of cells allows easy modification of specific regions of the domain wherein re-meshing requirements are limited to those cells housing modified elements and maybe some surrounding cells.

Abstract: A system, method and program product for managing hydrocarbon energy production. A hydrocarbon field modeler models physical characteristics of a hydrocarbon energy field. A load predictor predicts processing workload in modeling the hydrocarbon energy field, and identifying a balanced modeling unit distribution across multiple processors simulating field production. A load distribution unit distributes the modeling units across the processors for a balanced modeling unit distribution. The load predictor and load distribution unit proactively shifts loads to maintain workload balanced throughout the simulation.

Abstract: A method and computer program product for managing hydrocarbon field production, e.g., petro-chemical reservoir production. The hydrocarbon field is modeled using the finite volume method (FVM) model and the finite element method (FEM). Centroids are located in each FVM cell and each FEM element and overlapping cells are identified. After determining the distance between centroids for overlapping cells, fluid characteristics are mapped to the FEM element centroids, weighted inversely for distance between the respective centroids. A permeability/conductivity weighted average is determined for pore pressure and temperature of sub-volumes clustered around each FEM element node. Field production may be adjusted in response to FEM element node characteristics.
