Shell has filed an exploration plan on a new prospect in the Mississippi Canyon area of the deep-water US Gulf of Mexico, in close proximity to other finds targeting the Norphlet play, US records show.

The Anglo-Dutch supermajor has filed the EP on MC 522 and 523 for a prospect called Daylight South, about six miles north-east of its Dover discovery.

The location also lies about six miles south and three miles west of its Appomattox hub for its production in the Norphlet trend, which drew first oil earlier this year.

Drilling is projected to kick off around 1 January 2020 and last some 270 days.

The area lies 72 miles offshore in 7098 feet of water.

Shell has since 1987 held claim to MC 522, which is also the site of the Fourier discovery. The Anglo-Dutch supermajor leased MC 523 in 2015 with a 100% share and a bid of $1.02 million.
