PetroMod Schlumberger Application to 1-D Basin Modeling
PurposeBasin and Petroleum System Modeling • 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)
Conceptual Model Building Steps1. Structural and Stratigraphic Model2. Present day petroleum system analysis • Al-Hajeri and Al Saeed et al. (2009)
Generic Events Input Output • Al-Hajeri and Al Saeed et al. (2009)
Basin and Petroleum System Modeling 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)
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/marcellus/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 • Paleo-Heat flow • Sediment-Water Interface Temperature (SWIT) • Al-Hajeri and Al Saeed et al. (2009)
