Abstract: Inverse Methods in Secondary Hydrocarbon Migration
Modeling
Marek Kacewicz
Classic approaches in secondary hydrocarbon migration
modeling in three dimensions assume that generation of hydrocarbons,
migration
conduits, and flow parameters are well defined through geological time. In some cases, however, all that is known is the present-day situation represented by accumulations, shows' stains, etc. The question arises how this restricted information can be used to identify potential generation areas. Inverse algorithms of secondary hydrocarbon
migration
modeling have been designed to model fluid flow back through time. During the modeling, flow parameters, pressure, etc. change from present-day to initial conditions. The resulting potential kitchens are used in forward modeling to identify unknown hydrocarbon accumulations. We show some examples of how the me
hod can be used in prospect analysis and in basin scale exploration.
