TRANSCRIPT
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
• Al-Hajeri and Al Saeed et al. (2009)

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
•Al-Hajeri and Al Saeed et al. (2009)
Boundary Conditions McKenzie Model for Heat Flow during Rifting
Boundary Conditions: Heat flow (McKenzie Model)
