Source Rock Geochemistry Print E-mail

A major part of petroleum systems analysis is the evaluation of source rock effectiveness (the ability of source rocks to deliver hydrocarbons to prospects).  This involves the interpretation of analytical data (such as TOC, Rock-Eval and vitrinite reflectance data) to evaluate the quantity, quality and thermal maturity of hydrocarbon-generative organic matter contained within source rocks.  Such interpretations can offer valuable clues as to which hydrocarbon types (oil versus gas, dry gas versus wet gas, etc) might be expelled from the source rocks concerned, and which might therefore be expected to charge mapped prospects.  Armed with the results of this work, 3D-Geo can then integrate the interpreted data with thermal modelling software, and mapping products, to develop expulsion and migration pathways in order to high-grade permits and assist in prospect risking.
