The company expects the well will be online and producing at an initial rate of 100 barrels of oil per day and 200,000 cubic feet of gas per day in the next three weeks.

The well, which was drilled to a total depth of 11,025ft, was treated with 18,230bbl of fluid and 900,000 pounds (405kg) of proppant.

Advance said the Prudie Brown-10 well was a direct offset from the EER Brown Lease, which has produced more than 68,000bbl of oil and 100 million cubic feet of gas in less than three years of production.

It was also a step-out well on the Key East Prospect, identified and discovered by North American Energy from the Motherlode 3D seismic data.

Advance holds a 12.5% working interest in the Prudie Brown well.
