Chevron picks Subsea7 for Aseng gas tieback offshore Equatorial Guinea

The deepwater project will produce gas from a single well, exported to the Alen platform.
April 2, 2026

Chevron subsidiary Noble Energy has contracted Subsea7 to install subsea facilities for the Aseng gas monetization project offshore Equatorial Guinea, extending the two companies’ long-standing working relationship in the country.

The project involves a single-well tieback in 800 m water depth to connect the Aseng Field to the Alen platform.

Subsea7’s responsibilities cover transport and installation of about 19 km of rigid production flowline, 20 km of umbilicals, associated subsea structures and tie-ins.

Project management and engineering is taking place at the company’s Paris office, with support from teams in Lisbon and locally in Equatorial Guinea. Offshore activities should start later this year.

The Aseng Field currently produces oil via subsea wells connected to an FPSO.
