1 Application to 1-D Basin Modeling PetroMod Schlumberger

2 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 ) Purpose Basin and Petroleum System Modeling

8 Create new model

9 Conceptual Model Building Steps 1. Structural and Stratigraphic Model 2. Present day petroleum system analysis Al-Hajeri and Al Saeed et al. (2009)

10 Generic Events Input Output Al-Hajeri and Al Saeed et al. (2009)

11 Materials Main Input Sediment deposition (Stratigraphy) Erosion Lithology Petroleum System Elements (PSE) Total Organic Carbon (TOC) Kinetics Hydrogen Index Boundary Conditions Paleo-Water Depth (PWD) Sediment Water Interface Temperature (SWI-Temperature) Heat Flow Al-Hajeri and Al Saeed et al. (2009) Basin and Petroleum System Modeling

12 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 us/sourcerock_index/sourcerock_quanity/index.htm

19 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)

20 Boundary Conditions McKenzie Model for Heat Flow during Rifting

21 Boundary Conditions: Heat flow (McKenzie Model)
