During recent carbonate seismic interpretation projects of recently reprocessed 3D seismic data of an offshore field in Abu Dhabi, U.A.E., several carbonate intervals were mapped using post-stack Band-Pass frequency filtered amplitude and multi-attribute seismic volumes. Interpretation results of main reservoirs and overburden intervals played a major and an effective role in current and future drilling operations, project planning, and reservoir development scenarios.

Several examples from recent drilling, and reservoir and aquifer characterization projects will demonstrate how 3D seismic integration in field development can be critical for designing horizontal and highly deviated wells, planning disposal wells, and ultimately enhancing overall reservoir recovery through improved seismic based next generation geologic models.

Initial seismic processing and interpretation results and learnings were incorporated in latest reprocessing and reinterpretation strategy, where effective value of information methods were implemented in incorporating seismic impact on a major producing field. The paper will discuss briefly these methods but mainly concentrate on several reservoir/aquifer specific seismic impact on field development and drilling activities examples from various locations within the field. Specific reservoir simulation examples will demonstrate seismic direct supporting role of well history match.
