Application to 1-D Basin Modeling

PetroModSchlumberger

• 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

Basin and Petroleum System Modeling

Main Input

TOC: Quantity of organic carbon in source rock, both kerogen and bitumen.

HI: (S2/TOC) x 100An 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

Well Assignment

Well Assignment

• 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

• Paleo-Heat flow

• Sediment-Water Interface Temperature (SWIT)

Boundary Conditions
