Pyrolysis kinetics applied to prediction of oil generation in the Maracaibo Basin, Venezuela
Abstract
We use chemical kinetic parameters for oil generation derived from modified Rock-Eval and Pyromat instruments, coupled with thermal history models, to predict the timing and extent of oil generation in the Maracaibo Basin of Venezuela. The vitrinite reflectance model developed at Lawrence Livermore National Laboratory is used to calibrate thermal history models with measured vitrinite reflectance profiles. We examine the way differences in the kinetic parameters affect predictions of oil maturation in several parts of the basin with different thermal histories. Maturity indicators, such as H/C atomic ratio and API gravity, are compared to the calculated extent of oil generation. We use the comparison to check the accuracy of the coupled oil generation and thermal history models. 20 refs., 13 figs.
