U.S. energy giant Chevorn announced on Monday that it had struck oil at a deepwater well in the Gulf of Mexico off the coast in the state of Louisiana.
The new discovery is located at the Walker Ridge Block 98 well in the Coronado prospect, about 12 miles (about 19 kilometers) from another discovery announced last week by Anadarko Petroleum Corp and ConocoPhillips. Operating in 6,000 feet (about 1,800 meters) beneath the water, Chevron drilled through a thick underground salt layer to find oil at a depth of 31,866 feet below sea level, according to the website of The Houston Chronicle.
The company said at the above-mentioned well, workers encountered more than 400 feet of net oil pay, or the thickness of an oil reservoir that can produce hydrocarbons. The Coronado prospect is a part of a region dubbed as the Lower Tertiary Trend, which is especially challenging to drill because a thick underground salt layer makes seismic scans hard to read.
Chevron holds a 40 percent working interest in the Coronado prospect and is the operator of the Coronado discovery well. The new discovery was Chevron's second attempt to drill into the Coronado prospect after a 2011 effort was abandoned.
