Byron strikes pay at South Marsh Island

Written by  OE Staff Wednesday, 27 December 2017 13:58

Byron Energy has struck 190ft (58m) of net oil pay in the South Marsh Island Block 71 F-2 well in the Gulf of Mexico, exceeding initial expectations, partner Otto Energy reported today (27 December).

Drilled and logged to 8615ft measured depth with Ensco jackup Ensco 68, the well encountered the pay in four high-quality oil-bearing sands. Two of the sands, B65 and D5, hit net oil pay of 52ft and 117ft and are expected to be capable of high oil production rates, Otto said in a statement.

Each of the four sands have been productive in other areas of the South Marsh 73 field. The findings are based on logging while drilling (LWD) data; final pay counts will be calculated when LWD memory data becomes available and a petrophysical analysis completed.

During drilling of the well’s final section, the drill pipe become stuck about 214ft below the bottom of the D5 sand. Byron was working the afternoon of 26 December (US central time) to free the stuck pipe, Otto reported.

Byron is operator of the South Marsh Island 70/71 joint venture with 50% working interest. Otto holds 50% working interest in the block through a wholly owned subsidiary.
