Burial History and Thermal Modelling Print E-mail

Burial history and thermal modelling of source rocks is routinely performed within the petroleum exploration industry to gain insights into the degree and timing of source rock maturation within basins, particularly relative to the timing of trap formation, to assist with overall evaluation of hydrocarbon prospectivity and, more specifically, prospect-risking.
Such modelling is performed by 3D-GEO Chem using the state-of-the-art Zetaware modelling packages called GenesisTM and TrinityTM. The GenesisTM module is used to construct a series of 1D, temperature-calibrated models in wells from which reliable down-hole temperature and source rock maturity data are available, and to extend the resulting heat-flow models to pseudo-wells in structural lows/source-kitchens as required.  The temp-depth functions from all of these models are then introduced, together with all available depth-grids and source rock data, into TrinityTM, which facilitates the generation of maps of temperature, maturity, hydrocarbon-expulsion and migration on all the appropriate depth surfaces (and interpolated ones, as necessary), present-day and through time.  TrinityTM will also calculate information relevant to prospect evaluation and risking, such as the predicted GIP and OIP volumes, and GORs and CGRs, of modelled hydrocarbon accumulations.  As understanding of the effectiveness of the petroleum system matures, the GenesisTM-TrinityTM files can be revised and updated with new data, and the existing models progressively refined.
