W&T Offshore has announced the discovery of new, deeper reservoirs at the Mahogany field in the US Gulf of Mexico.
The Ship Shoal 359 A-18 well has logged 149 feet (45 metres) of net oil pay in five zones and extended the size and depth of the Mahogany field, the firm said in a statement.
The successful drilling of the A-18 well is expected to result in drilling at additional locations, W&T added.
“With a number of development and low-risk exploration locations yet to be drilled, the Mahogany field is expected to be the cornerstone of our capital programme in 2017 and possibly beyond,” said W&T’s chairman and CEO, Tracy Krohn.
“The A-18 success exceeded our pre-drill expectations and underscores the large potential in the prolific Mahogany ‘T’ sand,” said W&T’s chief operations officer, Tom Murphy.
The ‘T’ sand was discovered in mid-2013 by the A-14 well.
Another well, SS 349 A-18, was drilled to a total vertical depth of around 20,000 feet (6,096 metres) in water depths of 372 feet (113 metres). It is anticipated to come on line in the first quarter of 2017.
The US independent has a 100% working interest in the Mahogany field. It temporarily halted its drilling programme at the field in early 2015 owing to the drop in oil prices.
Houston-based W&T currently has working interests in around 54 fields in federal and state waters. Of these, 50 fields are currently in production.
The company also has around 750,000 gross acres (3,035 square km) under lease, of which 450,000 gross acres (1,821 square km) are located on the Gulf shelf, with the remainder located in deepwater areas.
