A method of determining composition of a mixture of H2S, CO2, and hydrocarbons, the method comprising:
- measuring attenuation of gamma photons in a gas mixture consisting essentially of hydrocarbons, CO2, and H2S;
- measuring temperature and pressure of the gas mixture;
- determining linear attenuation coefficients for the components of the gas mixture by measuring attenuation of the gamma photons in a representative gas mixture of H2S, CO2, and hydrocarbons;
- and
- determining composition of the gas mixture using the measured attenuation and the determined linear attenuation coefficients.
