Stone Energy has made two new discoveries in the US Gulf which look likely to end up as subsea tieback developments, one in deepwater and the other on the shelf.
The company reported that its deepwater Amethyst exploration well in Mississippi Canyon Block 26 encountered up to 27 m (90 ft) of net pay in a single interval, which it suggests is a commercial discovery. Well logs, coring and fluid data confirmed natural gas and liquids – with an estimated yield of 60–80 bbl of liquids per MMcf of natural gas, Stone said, and the hydrocarbon interval has been closed off for future re-completion.
Amethyst is less than 8 km (5 miles) from Stone’s 100%-operated Pompano platform, and could be developed via a single or multi-well tieback, it has suggested.
It also hit pay with its Tomcat deep gas exploration well in West Cameron Block 76, which encountered 9 m (30 ft) of natural gas and liquids in a Camerina interval.
