Dallas-based Aresco LP has successfully completed a deep Tuscaloosa Sandstone gas well in West Baton Rouge Parish.

The well was originally drilled in 2009 to a depth of 21,117 feet. Mechanical issues prevented the original operator from reaching the desired reserve. The well was completed in upper sands that had a smaller reserve potential.

In mid-2015, Aresco joined a lead operator and its capital partners and embarked on a targeted well reentry program. The result was “a significant new field discovery,” according to Aresco. The well produced 500 million cubic feet of natural gas during its first nine weeks of production.

Aresco’s Tuscaloosa Sands prospect features up to 22 in-field drilling locations with gross estimated reserves of 726 billion cubic feet of gas and 36.3 million barrels of oil.
