Simulation of basin evolution: tracking hydrocarbon generation and expulsion
•
Estimate volume hydrocarbon entrapment, flow and accumulation
•
Spatial scale: 10s to 100s of Kms.
•
Time scale: 100s to Mas
•
Dynamic reservoir geometry
•
1D model: examines burial history at a point location.
•
2-D model: either in map or cross section, can be used to reconstruct oil and gas generation, migration and accumulation along a cross section.
•
3-D model: reconstructs petroleum systems at reservoir and basin scales and has the ability to display the output in 1D, 2D or 3D, and through time •

Main Input
TOC: Quantity of organic carbon in source rock, both kerogen and bitumen. HI: (S2/TOC) x 100 An estimate of hydrogen richness in source rock. It help estimating maturity if kerogen content is known. HI-OI plot can give a rough assessment of petroleum generative potential of a source rock http://www.dcnr.state.pa.us/topogeo/econresource/oilandgas/marcell us/sourcerock_index/sourcerock_quanity/index.htm

Boundary Conditions •
Paleo-Water Depth (PWD) is an important parameter which controls the rate of sedimentation, erosion, and the volume of water controls pressure load on top of a system.
•
Temperature controls transformation of kerogen into petroleum •
