CREATING A THICKNESS GRID FOR DETERMINING RESERVE ESTIMATES FOR A RESERVOIR

摘要

Systems and methods for creating a thickness grid for determining reserve estimates for a reservoir by performing a fast sweep thickness extraction on a sealed triangulated mesh to create the thickness grid.

1. A method for creating a thickness grid for determining reserve estimates for a reservoir, which comprises:
creating a plurality of polylines by intersecting a vertical plane with a sealed triangulated mesh at a predefined slice interval along an x-dimension in spatial extents for the sealed triangulated mesh, each polyline including a first point and a last point; creating a plurality of polygons by connecting the first point and the last point on each polyline in a respective vertical plane; aligning each polygon perpendicular to the respective vertical plane; creating a grid wherein each grid node on the grid is initiated with a value of zero; computing a plurality of thickness values using each aligned polygon at a predefined thickness interval; and creating the thickness grid using a computer processor by assigning each thickness value to a respective grid node on the grid.
