METHOD OF DISCERNING WATER FROM HYDROCARBON FLUIDS USING DOWNHOLE NMR INSTRUMENTS IN PETROLEUM RESERVOIRS WITH FORMATION BRINE

摘要

A method for analytically separating properties of hydrocarbon materials from other materials in a downhole environment, the method including: performing nuclear magnetic resonance (NMR) measurements downhole; determining a signal for sodium-23 (23Na) from the NMR measurements; and associating the 23Na signal with the other materials. A computer program product, an apparatus and additional methods are provided.
