Shell subsidiary Shell Offshore Inc. said Feb. 22 it had started production at Rydberg, a subsea tieback to its operated Appomattox production hub in the Gulf of Mexico.

Rydberg, located in the Mississippi Canyon Block 525 area of the Gulf of Mexico, is expected to produce 16,000 boe/d at peak.

Rydberg is in about 7,450 ft water depth and holds an estimated 38 MMboe of recoverable resources. While Rydberg was originally discovered in 2014, Shell didn’t reach final investment decision on the project until 2022.

Shell developed the field using two production wells that produce through a single insulated 12-mile flowline to Appomattox, along with a dynamic umbilical.

The Appomattox production semisumbersible went online in 2019.

“Rydberg will further boost production in the Norphlet Corridor at Appomattox, which is consistently one of our highest producing assets,” Rich Howe, Shell deep water executive vice president, said in a press release.

Shell operates the leases containing the Rydberg discovery with 80% interest on behalf of partner CNOOC with 20% interest.

Shell operates Appomattox with 79% interest on behalf of CNOOC with 21% interest.
