Petrel Exploration Geology modules, Play to Prospect Risk, Petroleum System Quick Look and Petroleum Systems Modeling, enables a petroleum system-based analysis of prospectivity in an unbroken systematic workflow from the initial basin evaluation and development of the play concepts through to the identification, ranking, and drilling of the prospects. Additionally, the analysis of trap, reservoir, charge, and seal are accomplished using an integrated set of tool that all tie back to the geological evaluation of the plays.
