Geochemical framework coupled with fluid flow model makes up an integrated computer system for basin evaluation in actual petroleum exploration. The model in high dimensions are believed to be more sophisticated and to result in better solutions, however, a functionally-restricted one-dimensional model is also useful for evaluations of exploration potentials in frontier basins, where only sparse geologic data are obtainable. Two- or three-dimensional model needs more precise geologic data for its appropriate results, therefore, it might not work properly with such sparse data. One-dimensional model, which simulates petroleum generation and expulsion process under an independent cell condition, is successfully applied for this type of exploration setting. Using newly-developed version of maturity model, the method of determining paleo-heat flow is also discussed.
In the applications, the procedure sequence for one-dimensional basin analysis is introduced using the data from only one well in the Abu Dhabi area. Multi-well analysis is also demonstrated for areal evaluation of source rock potential in the Northwest Jawa area.
