New isotope geochemical concepts for natural gas exploration

By: Contributor(s): Series: Cramer, B ; Description: 2 pDDC classification:
  • CD W938 1 0013960
In: v. 1, p. 50-51Summary: Resumen del autor, extraído del autor. A new method is presented which provides possibilities to deduce the generation and accumulation history of natural gas from d13C-values of gaseous hydrocarbons. This approach consists of two parts, a new analytical technique and a numerical model. It establishes a direct, deterministic link between the process of thermal hydrocarbon generation, commonly described by chemical reaction kinetics, and the stable isotopic composition of hydrocarbon gases generated by this process. It addresses questions regarding the timing of entrapment, the amount of accumulated gas, the size of the recharge area or the amount of actively producing source rock as well as questions regarding reservoir compartments. In this way reaction kinetic models of stable isotopes in natural gas potentially become a powerful tool in basin simulation studies.
