Exploration and appraisal drilling is underway at the Gemini subsalt discovery located in Mississippi Canyon 292 in approximately 3300 feet of water. Gemini is a significant Gulf of Mexico deepwater natural gas and oil discovery made under joint partnership with Texaco Exploration and Production, Inc. and Chevron U.S.A. Production Company, Inc. Multiple hydrocarbon-bearing sands all lie beneath a tabular salt sheet. Seismic artifacts from the salt and subsalt make interpretation a challenge. Yet, reservoir geometries can be observed from 3-D depth- migrated seismic data and integrated with high-resolution logs, analog studies of other similar fields, and detailed core analysis.
The sands and their associated anomalies reside near the crest and flank of a large faulted structure. These reservoirs are within a deep water, sand-rich, channel-levee system and may be best described as thin-bedded turbidites with significant lateral extent. Two stratigraphically different reservoirs with similar thin-bedded characteristics were perforated and tested. One zone tested at 22 MMCFGPD and 3,778 BOPD, while the other zone tested at 32 MMCFGPD and 627 BOPD.
