System and method for computations utilizing optimized earth model representations

摘要

A method and corresponding system is provided for computation utilizing an earth model representation via a computing system having a first processor having access to an earth model dataset. The method includes compressing the earth model dataset at the first processor to generate a look-up table and a set of data indices (i.e., collectively a compressed earth model representation), wherein the look-up table includes quantized data values. By then storing the look-up table in a first level (“fast”) memory, and storing the indices in a second level (“slower,” higher memory capacity) memory, the look-up table and the indices can be accessed to selectively decompress the compressed earth model representation at the first processor such that the computation can be performed efficiently by the first processor.
