Forward models for gamma ray measurement analysis of subterranean formations

摘要

Methods and related systems are described for predicting a response of a gamma ray measurement tool located in a borehole surrounded by a subterranean formation. A response of the tool is calculated according to one or more properties at a plurality of spatial locations in relation to the measurement tool using a forward model that assumes a non-linear relationship between the one or more properties at the plurality of spatial locations and the corresponding response of the tool.
