HOUSTON –W&T Offshore (NYSE: WTI) has a subsalt discovery in a deep shelf exploratory target beneath its Ship Shoal 349 Mahogany field in the Gulf of Mexico.
The SS 359 A-14 well exceeded expectations, said the company, and is producing from the targeted T-Sand at an initial flow- back rate of 3,030 b/d of oil and 5.6 MMcf/d of gas. Flowing tubing pressure is about 9,400 psi (64.8 MPa) surface pressure.
The T-Sand is the deepest sand discovered in this field, as there is additional pay identified in the M-Sand, N-Sand, and O-Sand, all of which represent future reserve additions said W&T. The well also penetrated a thicker than expected P-sand interval (the main field pay sand) which will also serve as a future recompletion.
In total, the A-14 well logged more than 370 ft (113 m) of net oil pay, with the T-Sand accounting for 108 ft (33 m) of the total net pay.
W&T holds a 100% working interest in the field.
The platform rig at Mahogany is currently working on a recompletion in the A-4 well designed to bring a behind pipe P-Sand interval into production at an expected rate of 1,000 boe/d, with a production date of August or September.
Following this recompletion, W&T expects to spud the A-15 subsalt exploratory well, scheduled to reach total depth near the end of 2013 or early 2014.
The unrisked reserve potential associated with the A-15 well is anticipated to be in the range of 1.8 to 6.2 MMboe, said W&T.
