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.
