Understanding the complex geometries of entrapment and patterns of fault-influenced fluid now is critical in drilling and workover decisions. The task at the Teak field, offshore Trinidad, is complicated by poor seismic resolution over much of the field. 3D geological interpretation and visualization technology has enabled recognizing, evaluating, targeting, and successful drilling of undrained stacked compartments. The full 3D model has aided the design of well trajectories that successfully avoid or adequately prepare for problematic pressure-depleted intervals.
