The well has achieved a production rate of 3,275 b/d of oil and 5.6 MMcf/d of natural gas for a total of about 4,200 boe/d at a flowing tubing pressure of more than 9,000 psi. The company expects to increase the A-18 production rate to in excess of 5,000 boe/d consistent with its reservoir management plan.
As previously reported, theSS 349 A-18 well logged 149 ft (45.4 m) of net oil pay in five zones and extended the size and depth of the Mahogany field. The well was completed in the main objective ‘T’ Sand, with future recompletion opportunities to additional pay zones available in the well.
This deep shelf subsalt well was drilled to a total vertical depth of approximately 20,000 ft (6,096 m) in a water depth of 372 (113m) ft on the western side of the Mahogany field.
W&T holds a 100% working interest in the Mahogany field.
Chairman and CEO Tracy Krohn said: “The SS 349 A-18 well is proving to be another substantial producer from an outstanding field that continues to expand in size. With its high quality rock properties, including very high porosity and permeability, we anticipate strong production rates from this well for years into the future.
“Our SS 349 A-14 well that originally discovered the 'T' sand in July 2013 has produced a total of 3.8 MMboe gross from the 'T' sand to date. As a result, the economic returns on these wells are excellent.”
