PetroMod petroleum systems modeling software combines seismic, well, and geological information to model the evolution of a sedimentary basin. The software predicts if, and how, a reservoir has been charged with hydrocarbons, including the source and timing of hydrocarbon generation, migration routes, quantities, and hydrocarbon type in the subsurface or at surface conditions. Large-scale geologic petroleum systems models (1D, 2D, or 3D) cover areas ranging from a single charge area for a prospect to regional studies of entire basins to multibasin resource assessments. The models are dynamic, which means they provide a complete record of the structural evolution, temperature, and pressure history, as well as the effects on generation, migration, accumulation, and loss of oil and gas in a petroleum system through geologic time. Properties such as gas/oil ratios (GOR) and API gravities can be analyzed, understood, and predicted. Petroleum systems modeling (PSM) is a vital component of exploration risk assessment—from basin to prospect. It can be applied during all stages of exploration, from frontier basins with no well control, to well-explored areas and charge assessments of single prospects or fields. Even in producing areas, charge risk on a prospect scale is an essential component of a fully integrated risk assessment. The 3D petroleum systems model includes all the key elements of geological risk in exploration (trap, reservoir, charge, seal, and timing of hydrocarbon generation, migration, and loss) and enables rigorous risk analyses. ​​​​​ PetroMod software is the only petroleum systems modeling package covering the entire workflow for 1D, 2D, and 3D modeling. It is also the only product to use the same simulators; all technical features and tools are available—and identical—in all dimensions. PetroMod software can also use different simulation methods with the same data models for analyzing the petroleum system in your area and to better evaluate uncertainties in hydrocarbon migration and accumulation. Integration with the Petrel E&P software Platform provides a unique systematic exploration workflow.
