Method and System for Petrophysical Quantity Estimation from Dielectric and Neutron Capture Cross Section Measurements

摘要

In one embodiment, a method includes receiving, via a processor, dielectric measurements of a geological formation and receiving, via the processor, sigma measurements. The sigma measurements include thermal neutron capture cross section of the geological formation. The method also includes jointly inverting to fit the dielectric measurements and the sigma measurements to a petrophysical model, and computing at least water salinity of the geological formation based on the joint inversion.
