In most petroleum companies, each element of the petroleum system is addressed through peer reviews and risking sessions. These elements are: source presence and its characteristics, source maturity, migration (carrier beds), reservoir, trap and seal. An additional risk is oil quality or its preservation. More than half of the risk associated with a prospect or play fairway is assessed via petroleum geochemistry and burial history / thermal / fluid-flow basin modeling. This article will present how regional data, paleo-reconstructions, seepage data via piston coring and 2-D burial history / th ..read more
