Detecting and quantifying hydrocarbon volumes in sub-seismic sands in the presence of anisotropy

A method to detect presence of hydrocarbons in a subterranean formation. The method includes identifying a geological interval in the subterranean formation, analyzing a measurement of a rock sample obtained from the geological interval to generate a rock sample analysis result, wherein the rock sample analysis result indicates the presence of hydrocarbons in the geologic interval, analyzing, in response to the rock sample analysis result indicating the presence of hydrocarbons, a supplemental measurement different than the measurement of the rock sample to generate a supplemental analysis result, wherein the supplemental analysis result further indicates the presence of hydrocarbons in the geologic interval, performing, in response to the supplemental analysis result further indicating the presence of hydrocarbons, a logging operation to obtain azimuthal resistivity data of the geological interval, and presenting the rock sample analysis result, the supplemental analysis result, and the azimuthal resistivity data to a user.
