Structural and stratigraphic interpretation using dual-coil 3-D seismic data, fault-seal analysis, and pressure and fluid data are enabling Hess to extract higher-order reservoir details to optimize the development of the deepwater Stampede Field. The state-of-the-art subsurface model will be updated with new data each time a development well is drilled to optimize overall performance and refine future drilling and completion strategies. 56 THE AMERICAN OIL & GAS REPORTER
