Abstract

Alkyl monoester tracers (e.g. ethyl acetate) have previously been used in a single well chemical tracer test to determine residual oil saturation. We propose here to use diesters (e.g. propylene glycol diacetate) and triesters (e.g. triacetin) for determining residual oil saturation and residual carbon dioxide saturation. These tracers have a much lower flash point making them much safer and potentially expanding their application. Compared to the monoester tracers, the proposed tracers have similar reactivity, partition coefficients and water solubility. We have recently tested these tracers in the field to determine residual carbon dioxide saturation and obtained tracer breakthrough profiles suitable for analysis using computer simulations.
