NMR ANALYSIS OF SUBTERRANEAN RESERVOIR SAMPLES IMMERSED IN LIQUID HALOCARBONS

摘要

A sample of a subterranean formation is prepared for NMR analysis by saturating the sample with an aqueous liquid and then immediately immersing it in a liquid halocarbon. An NMR analysis is conducted on the immersed sample. The liquid halocarbon does not have hydrogen atoms bound thereto which would interfere with the NMR analysis and preferably has a sufficient viscosity to substantially eliminate the displacement of aqueous liquid from the sample. The sample can be stored in the liquid halocarbon for maintaining aqueous liquid within the sample. 79043ART0082
