ABSTRACT:
Residual oil saturation is determined by injecting water containing CO.sub.2, a base-generating material and at least one radioactively labeled material which is or becomes a selectively water-soluble tracer material mixed with the injected CO.sub.2, so that the arrival of the oil and water-partitioning tracer material is demarked by a decrease in CO.sub.2 concentration and the arrival of at least one of tracer material detected by a radioactivity analysis.
