Three-dimensional mapping of seismic data revealed a prospect not existing on the 1000 2-D grid. A bright spot was reviewed downdip of an abandoned competitor well that had apparently been faulted out. Normal 3-D mapping resulted in a new well proposal, but results from interactive workstation analysis moved the location downdip. Detailed structural and amplitude analyses revealed the presence of complex stratigraphic changes within the prospective reservoir, which were then avoided in a successful discovery well. Predictions of net pay and reservoir connectivity were confirmed. Future management of this reservoir will also be better served with combined geological, engineering, and geophysical analyses.
