Abstract

Disclosed is a method of determining the extent of recovery of materials injected into a oil well comprising the steps of : a) preparing a material to be injected into an oil well ; b) admixing therewith a chemical tracer compound at a predetermined concentration ; c) injecting the admixture into an oil well ; d) recovering from the oil well a production fluid ; e) analysing the production fluid for the concentration of the chemical tracer present in the production fluid ; and f) calculating the amount of admixture recovered from the oil well using the concentration of the chemical tracer present in the production fluid as a basis for the calculation. Fluorinated benzoic acids are disclosed as a preferred tracer.
