摘要： A method is disclosed for using a three-dimensional seismic image of a subsurface earth volume to construct a geologic model specifying the spatially-varying grain size distribution, porosity, and permeability throughout the volume. The method applies to earth volumes composed of water-lain clastic sedimentary deposits and involves, in one embodiment, (a) identifying the outline forms of geologic bodies in geologic data; (b) using the outline forms of the geologic bodies to determine the spatially-varying grain size distribution within the bodies, guided by assumptions about the nature and behavior of the paleoflow that deposited the bodies; (c) determining rock properties such as, porosity and permeability within the geologic bodies based on grain-size distribution, mineralogy and burial history information.

摘要： The invention is a method for simulating sandstone deposition. The sandstone is simulated by estimating the grain size distribution and mineral composition of grains in the sandstone, simulating sedimentation of grains from the grain size distribution and mineral composition of the grains, simulating compaction of the grains, and simulating cementation of the grains. Properties of the sandstone such as porosity and permeability may be estimated from the simulated sandstone. The method permits multiple mineralogies to be simulated during the burial history of sedimentation, compaction and cementation.
