Shenzi OBN: An Imaging Step Change

Back to Technical Content
A new OBN survey was acquired over the Shenzi field in the deep water GOM. The primary goal was to leverage recent advances in FWI to improve the velocity model with an expectation that the image would benefit from the full-azimuth, long offset OBN data as well. We discuss the project from feasibility/survey design study to OBN FWI update and its accuracy to the imaging uplift. As it turned out the best image for steep dips and faults was the FWI image and its impact on the seismic interpretation was significant.
