Abstract
ABSTRACT
A method is disclosed for using a pair of tracers to determine the in-situ residual oil saturation surrounding a single wellbore in subterranean reservoirs. The first tracer has a labile hydrogen atom, and the second tracer is formed by substitution of a hydrogen isotope, i.e., tritium or deuterium, for this labile hydrogen atom. The mixture comprising the tracer and its isotopic form is injected into the reservoir where the isotope exchanges with non-isotopic hydrogen from the reservoir water. The produced sample is analyzed for the presence of both tracers, and the residual oil saturation is calculated.
