Deepwater's Dirty Work Just Got a Dream Team

Archer and SLB win a joint P&A contract from Equinor to permanently close three deepwater wells in the Mississippi Canyon

24 Mar 2026

Archer and SLB have been awarded a joint plug and abandonment contract by Equinor for its Titan platform, located roughly 63 miles offshore in the Mississippi Canyon. Announced in January 2026, the deal covers the permanent closure of three deepwater wells and consolidates project management, well engineering, coiled tubing, wireline services, and downhole technologies under a single delivery team.

The arrangement reduces the coordination complexity that has historically made deepwater decommissioning -- the permanent sealing of end-of-life wells -- difficult to execute on time and within budget.

The two companies bring distinct strengths. Archer is a plug and abandonment specialist that has expanded its US footprint through acquisitions in fishing and well intervention, services critical in complex deepwater settings. SLB brings a broad technology portfolio and an established operational presence in the Gulf of America.

The contract reflects wider structural change in the basin. The Gulf holds a large inventory of legacy wells from decades of offshore production, many nearing or past the end of their operational life. US regulators require the permanent closure of these wells, and enforcement has grown more rigorous. Demand for specialist decommissioning services is expected to rise as that inventory ages.

For Archer, the Titan award follows a run of major plug and abandonment wins in the North Sea during 2025, and signals a clear commitment to the Gulf of America as a growth market. For SLB, the collaboration extends its decommissioning capabilities in a region where it already holds significant infrastructure.

The deal points to a broader industry trend: as aging offshore assets multiply, operators are increasingly seeking integrated service partners capable of managing the full decommissioning cycle rather than assembling piecemeal contractor teams.
