W&T Offshore has discovered a significant hydrocarbon reserve at the Ewing Banks 954 A-8 exploratory well in the Gulf of Mexico.
The well represents the second discovery in a two-well drilling programme from the EW 910 platform.

A previous discovery was made at the ST 320 A-5 well in May 2015 and was also drilled from the same platform.
EW 910 platform is operated by W&T Offshore with a 50% working interest.
W&T Offshore noted that the well penetrated a total of 150ft of measured depth hydrocarbon pay contained in two sands.
W&T Offshore chairman and CEO Tracy Krohn said: "We are especially pleased with the high-quality pay sands found in the A-8 well, which should allow for higher reserve recovery.
"This discovery also helps de-risk several additional opportunities we have identified as part of our future plans to drill and develop the area."
Completion operations are going on at present, with a planned two-zone completion.
First production from the well is expected during the first quarter of 2016 after completing facility tie-in.
The company anticipates to produce at a gross rate of about 2,300boe per day from the two zones.
