West Carina completes 18-well campaign in Búzios

Seadrill’s drillship West Carina has completed its drilling and completion campaign in the Búzios field after more than three years of operations.

According to the company, the rig delivered 18 wells while supporting the expanded use of Managed Pressure Drilling in one of Petrobras’ most technically demanding offshore developments.

West Carina also became the first rig in Seadrill’s fleet to deploy Pressurized Mud Cap Drilling and Floating Mud Cap Drilling techniques.

In a previous operation disclosed by Seadrill, the use of PMCD reduced drilling time from 32 to 12 days, illustrating the potential impact of the technology in challenging pre-salt formations.

The drillship remained in Brazil through successive contract extensions, with its latest term running through June 2026.

Seadrill has not disclosed the rig’s next assignment.
