A method for determining an amount of hydrogen sulfide produced by a phenomenon of aquathermolysis induced by a thermal process, such as steam injection.

On the basis of a compositional representation of the hydrocarbons, an elementary reaction scheme is defined that is representative of a material balance for the element sulfur, as well as a system of reactions representative of the aquathermolysis reaction. Then a kinetic model is constructed taking into account the reaction scheme, the system of reactions, atomic balances relating to each of the reactions and relating at least to the sulfur, carbon and hydrogen atoms. Then a thermodynamic model is constructed and the resultant thermokinetic model is calibrated on the basis of experimental measurements. Finally, an amount of hydrogen sulfide is determined by performing a compositional reservoir simulation taking into account the resultant calibrated thermokinetic model.
