Subterranean flood tracer process

摘要

A method for determining the injection source of an injection fluid which will break through at the production wells of a subterranean flooding project is disclosed in the preferred embodiment. The source of the injection fluid is determined by injecting halocarbon tracer compounds into the fluid stream injected into the subterranean formation. The tracer compounds of the injection are identified by gas chromatography/electron capture detection analysis.
