In a boost to rig activity in the US Gulf, Harbour Energy's subsidiary, LLOG Exploration Company LLC, has extended contracts with Seadrill Limited, adding approximately US$260mn to the drilling contractor's contract backlog.

The year-long contract extension secures ultra-deepwater drillship West Neptune's services for operations that are set to start in September 2026. On the other hand, the West Vela ultra-deepwater drillship will be operating for an additional duration of 270 days, which is likely to commence in August 2026.

“We are pleased to extend our working relationship with LLOG, building on more than a decade of productive collaboration and shared success. The strong operational performance delivered by the West Vela and West Neptune teams continues to help us win follow-on work,” said Seadrill's President and Chief Executive Officer, Samir Ali.

“Securing this backlog enhances revenue visibility and supports free cash flow generation as we navigate near-term softness in the US Gulf. The West Vela and West Neptune are positioned favourably for availability in 2027 as global floater utilisation is expected to improve,” he said.

This follows the last contract extension between Seadrill and LLOG Exploration for a four-month programme in the US Gulf, which secured approximately US$48mn to Seadrill’s backlog.

The Sevan Louisiana had also received a contract award in the US Gulf from an undisclosed operator for a two-month programme. This engagement is set to start directly after its current contract with Walter Oil and Gas. The campaign will mark the first use of the Trendsetter well-intervention equipment in the region.
