NEW TRACERS FOR THE STUDY OF AN OIL RESERVOIR IN HIGH SALINITY AND HIGH TEMPERATURE CONDITIONS

摘要

The invention relates to the use of a compound of the general formula (I), wherein A represents an alkanediyl radical having 2 to 4 carbon atoms, which may be substituted by one or more methyl and/or ethyl groups, and either R represents a linear or branched C₁ to C₄ alkyl group and R′ represents a hydrogen atom, or R and R′ are linked together to form a cycle, and the —R—R′— radical represents —CO—, as a tracer for use in a Single-Well Chemical Tracer Test, to determine the Residual Oil Saturation in oil reservoirs.
