The main goal of petroleum system analysis in modelling software is time and depth reconstruction of generation, expulsion, migration and accumulation processes in sedimentary basin. The primary tools in this analysis are 1-D, 2-D and 3-D petroleum software.

1D Modelling
One-dimensional modelling, in well profile scale, allows to reconstruct the postdepositional history of a basin, with particular emphasis on geological evolution and thermal history.
Geological events (deposition, hiatus, erosion) and heat flow reconstruction in a sedimentary basin analysis allows to determine initial time of gas and oil generation process, as well as further it development in geological time scale. A multi variant choice of kinetic parameters that create an individual regimes for hydrocarbon generation and expulsion processes is available in 1-D modelling software. This multi variant choice allows to assess the model responsiveness to each geological and thermal values. Main geological and thermal values are: thickness of erosion, thermal gradient or heat flow, lithology of well profile. The tests and calibration of the basic geological, thermal with measured geochemical parameters that can be extrapolated within sedimentary basin in 2-D and 3-D models.

2D Modelling
Two-dimensional modelling allows to create a spatial numerical reconstruction of petroleum processes from the beginning of the hydrocarbon generation till its final accumulation in the trap. Cross-section with define regional geological, thermal and geochemical as well as reservoir parameters used in interactive modelling procedure define not only time of each process but also the regional range in the sedimentary basin. It totally fulfill the goal of detailed petroleum system definition.
Regional time and spatial analysis gives possibility to determine and observe alternate steps of oil and gas filed creation, starting from growing source rocks maturity until final hydrocarbon accumulation in the trap.
In 2-D modelling can be used geological cross-section from seismic-sections as well as interpretation of geological maps. Lithology within each stratigraphic section is define as a mixed basic lithology types in percentage. Other parameters like temperature, heat flow, source rocks characteristics can be define in spots, beds or layers along cross-section and then extrapolated in mathematical calculation in cells. Resolution of model depends of its size, geological and tectonic complicacy.
In the result of 2-D modelling, petroleum elements and processes can be presented in time and depth scale not only along cross-section, but also in each basin spot.

3D Modelling
Three-dimensional modelling is based on maps with editing horizons and maps options.
The 3D petroleum system 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.
