Petromod Introduction

PetroMod Schlumberger

Application to 1-D Basin Modeling

Purpose Basin 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 •

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 •

Paleo-Heat flow

•

Sediment-Water Interface Temperature (SWIT)
