Oct. 24 visit - Christof Stork, Halliburton/Landmark Graphics

Paul Fowler Christof Stork led discussions at the CWP I-team meeting on the subject of full wave inversion (FWI). He introduced, then raised interesting issues concerning FWI. One case in point: do we ask ourselves enough in FWI as to whether or not we have enough and credible data from the parts of a model in which we are truly interested? Considering the overwhelming data that may be present from other parts of the model (especially up shallow), do we take those into account in FWI through data and model conditioning? Christof created plenty of discussion during the meeting attended by CWP faculty, students and friends (Paul Fowler from Schlumberger/WesternGeco, Joe Stefani from Chevron Energy Technology Company).

Oct. 17 visit - Paul Fowler, Schlumberger/WesternGeco
