Title:
METHOD FOR CONSTRUCTING A GEOLOGIC MODEL OF A SUBSURFACE RESERVOIR
Document Type and Number:
WIPO Patent Application WO/2005/104003
Kind Code:
A8
Abstract:
The present invention is a method for constructing a geologic model of a subsurface reservoir which is a composite sedimentary body (30) composed of many smaller fundamental sedimentary bodies (32). In one embodiment, the fundamental sedimentary bodies (32) within the composite body (30) are specified by the properties of the flow which built them, including the flow properties that existed at the local inlet (36) of each fundamental body (32). The statistical distribution of these local inlet properties is characterized throughout the fundamental composite sedimentary body (30) using either outline forms of some of the fundamental sedimentary bodies (32) or a well penetration core which samples the composite sedimentary body (30). The geologic model is constructed by placing an appropriate statistical distribution of the fundamental sedimentary bodies (32) into the outline form of the composite sedimentary body (30) so that the grain size distribution and/or other geologic properties are is specified at each point within the composite sedimentary body (30).
