From playing a key role in the Gulf of Mexico, and Macondo deepwater oil spill response to end-of-life P&A work, Helix Well Ops is the global leader in rigless subsea well intervention, providing efficient, flexible, and high-quality well management services.
With more than 1,750 subsea well interventions performed globally, our project teams and offshore crews deliver unrivaled experience and real-world expertise.
Our purpose-built riserless and riser-based well intervention vessels and subsea systems can be mobilized worldwide to provide customer value throughout the well life cycle, enhancing production from deepwater and shallow water subsea wells through wireline, coiled tubing intervention, hydraulic stimulation, and dry tree intervention.
We perform these types of subsea well intervention works at project costs significantly lower than drilling rigs, with the versatility to perform both riser-based and riserless interventions.
In addition, we can also perform a variety of decommissioning operations including temporary and permanent plugging and well abandonment, pipeline abandonment services, reclamation and remediation services, wellhead removal, production tubing recovery and more.
Maximizing reserves of existing subsea fields
Deepwater Abandonment Alternatives (DAA), a wholly owned subsidiary of Helix, enables Helix to own, operate, and abandon satellite wells and subsea infrastructure located in the deepwater GOM. We offer more than well suspension services – we provide proven production enhancement services for subsea and topside wells and a highly skilled workforce for full-field decommissioning services.
DAA will acquire ownership in subsea wells and infrastructure having modest production and limited value in transactions that have a low purchase price or are acquired on assignment. Helix is a low-risk option to abandon wells and infrastructure in the deepwater Gulf of Mexico (GOM) with a history of safe operations that have been performed by BOEM / BSEE regulations.
Helix has a proven track record in the worldwide deepwater abandonment business having worked on abandonment and suspension operations in the UK North Sea, Brazil, Australia, West African and Gulf of Mexico. Helix has been successful in acquiring and safely operating production in the GOM, as evidenced by its experience spanning 20+ years with a prior subsidiary, Energy Resource Technology (ERT).
Helix Fast Response System
The Helix Fast Response System (HFRS) is a compilation of Helix’s company’s unique assets, experience, preparedness, dedication to industry safety, and past offshore spill response emergencies.
Based on the lessons learned and technologies developed from the BP Macondo spill response in 2010, Helix developed the HFRS to respond to a future spill. The HFRS combines services offered by both the Helix Producer I (HPI) and either the Q4000 or the Q5000 vessels, depending upon availability and location. Calling off working vessels is operationally preferable to a modular system that would take longer to deploy and may go untested for extended periods. Using the proven methodologies from the Macondo oil spill to provide spill response capacity, the HFRS continues to be named as a well control resource in customers’ permit applications and is a powerful tool in the industry’s arsenal to help mitigate and remediate the environmental risks associated with offshore drilling and production operations in the Gulf of Mexico.
Since February 2014, the Helix HFRS has been cited as the spill response system of record for nearly 160 new drilling permits issued in the Gulf of Mexico. At full production capacity, the Helix Producer I can produce 55,000 BOPD and 95 MMSCFD of gas at 10,000 psi in water depths to 10,000 feet. In addition, The Q4000 and Q5000 are each able to deploy the cofferdam to contain a spill, burn off oil and gas from the well, and in past services, have recovered the blowout preventer. Each vessel has been outfitted to accommodate a temporary process package that can handle 130,000 BOPD and 220 MMSCFPD at 10,000 psi in water depths to 10,000 feet.
