    摘要： An enhanced multi-point statistical (MPS) simulation is disclosed. A multiple-grid simulation approach is used which has been modified from a conventional MPS approach to decrease the size of a data search template, saving a significant amount of memory and cpu-time during the simulation. Features used to decrease the size of the data search template include: (1) using intermediary sub-grids in the multiple-grid simulation approach, and (2) selecting a data template that is preferentially constituted by previously simulated nodes. The combination of these features allows saving a significant amount of memory and cpu-time over previous MPS algorithms, yet ensures that large-scale training structures are captured and exported to the simulation exercise.

    摘要： A method of performing a simulation of a subsurface hydrocarbon reservoir. The reservoir is approximated by a reservoir model having a plurality of cells. Each cell has an equation set representing a reservoir property. An initial guess is provided to a solution for a system of equations formed using the equation set for each of the cells. An iterative root-finding method and the initial guess are used to solve for a solution to the system of equations. When the number of non-converged cells is greater than a predetermined amount, neighboring converged cells are added to the non-converged cells. Parts of the method are repeated, substituting the solved solution for the initial guess and the equation sets corresponding to the non-converged cells for the first system of equations, until substantially all equation sets satisfy the convergence criterion. The solved solution is outputted as a simulation of the subsurface reservoir.

    摘要： Irregular volumes within one or more three-dimensional volume datasets are identified and extracted in response to criteria. The processing involves automatically finding a seed voxel or seed cell that meets the criteria and thus belongs to an irregular volume of interest, and then identifying cells related to the seed cell by one or more predetermined relationships that are therefore also to be grouped into that irregular volume. Information, which can be of any suitable type, identifying each such cell as being related to other cells and belonging to an irregular volume is stored in a suitable data structure. The location or similar neighborhood information and other data describing properties or attributes of the identified cell are also stored. Because the irregular volumes are extracted and pre-processed in this manner, operations including rendering them on a display and performing Boolean and arithmetic operations on them can readily be performed.
