Talos Energy Inc. discovered pay from the Tornado 3 sidetrack (Tornado Attic) in Tornado field, 3 miles south of Talos’s Phoenix complex in Green Canyon, Gulf of Mexico. Tornado Attic was designed to optimize recovery and was drilled about 4,500 ft from the Tornado water flood injection well and 1,550 ft from the closest existing producer well.
Seadrill’s West Neptune rig conducted the drilling and encountered about 85 gross (63 net) ft true vertical thickness pay in the B6 Upper Zone with rock and reservoir properties consistent with internal modeling and pre-drill expectations. Talso will immediately move to the completion phase.
Talos started the intra-well waterflood project in 2020, drilling an injection well which sources water from a large aquifer above the producing B-6 sand. Known as a dump flood, the project is one of the first of its kind in a subsea, deepwater environment, according to Talos.
The higher-pressured aquifer naturally injects more than 20,000 b/d of water into the lower-pressured producing reservoir at the downdip boundary of the geological formation, creating reservoir energy to help maintain production and increase ultimate recovery throughout Tornado.
Production from Tornado Attic is expected by third-quarter 2021 at 8,000-10,000 boe/d gross (about 80% oil).
Talos is operator of Tornado field (65%) with partner Kosmos Energy (35%).
