With a significant prospect portfolio at hand, it becomes important to achieve the best possible risking and volume estimates in order to drill the best prospects as early as possible.

The figure shows how CSEM data can change both volume estimates and Probability of Success for a portfolio of prospects.

Creaming curves in a region typically indicate a degree of trial and error in the search for the largest targets. Improvements in portfolio polarization moving the most promising targets up-front will have enormous economic value for the industry.

The CSEM data response of a resistivity anomaly is directly proportional to the volume of the anomaly and can delineate the charged reservoir. Therefore, CSEM can significantly improve exploration decision making, pointing towards the high graded targets, and help avoiding drilling dry or non-commercial wells.
