摘要
A method for quantitative monitoring of a gas injected into a reservoir and likely to react chemically with the injection medium includes injecting into a reservoir a mixture of the potentially reactive gas to be quantified with a low proportion of a tracer gas whose chemical inertness is total, and in determining the variation with time of the initial proportion of reactive gas that may have disappeared through conversion, by measuring the concentration variation of the tracer gas in the mixture. The tracer gas is preferably selected from the rare gas family and from isotopes thereof, unlikely to be contaminated by contact of the mixture with the injection medium, and which have physical properties such as solubility in water or diffusion coefficients as close as possible to the gas injected. The method is applicable to monitoring of the evolution and conversion of a reactive gas such as carbon dioxide or methane, injected into an underground reservoir for example.
