Talos Energy is growing production at the Phoenix Field in the U.S. Gulf of Mexico’s Green Canyon area, with the Tornado II deepwater well flowing more than 12,350 barrels of oil equivalent per day (boe/d) during a two-week test in December 2017.

The Houston-based company, which is set to merge with Stone Energy Corp. (NYSE: SGY), released IP results from the well on Jan. 16. The well is located in about 823 m (2,700 ft) of water.

Talos said the Tornado II drilling program consisted of an exploratory test penetration in a fault block adjacent to the company’s initial Tornado discovery in 2016, followed by the Tornado II producer to delineate and further develop the initial reservoir. More than 80% of the gross production from the Tornado II deepwater well during the test was oil.

Coupled with the first Tornado well, Talos said it plans to flow the wells at a combined gross rate of between 24,000 boe/d and 27,000 boe/d. The wells flow through the existing Phoenix Field subsea infrastructure into the Helix Producer I floating production unit on the adjacent Green Canyon Block 237, the company said in a news release.

Talos serves as operator with 65% interest. Its partner is Deep Gulf Energy III with a 35% working interest.
