Helix Well Ops

Rigless Offshore Well Intervention.

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 1,850 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.

Helix’s well intervention services allow our customers to safely access subsea offshore wells for production enhancement or decommissioning operations. This approach reduces the need for new wells by extending the life of existing wells and helps protect the environment by preventing uncontrolled releases of oil and natural gas.

Our well intervention fleet includes the Q4000, Q5000, Q7000, Seawell, Well Enhancer, and two chartered monohull vessels, Siem Helix 1 and Siem Helix 2. We also offer well intervention equipment, such as intervention riser systems (IRSs), subsea intervention lubricators (SILs), and the Riserless Open-water Abandonment Module, some of which are available on a stand-alone basis.
