An integrated approach to subsea well services

The Subsea Services Alliance combines the expertise and capabilities of Helix and Schlumberger to form an advanced subsea well construction, intervention, and decommissioning portfolio: including marine support, well services, project management, and subsea well access and control. Schlumberger technology segments provide a complete offering of intervention and completion running technologies, and are joined by OneSubsea, a Schlumberger company, for subsea production systems. Helix contributes marine support, operational expertise, and project management capability.

Eliminating the need to use drilling rigs for support, the Alliance commands vessels that can handle well commissioning, intervention, artificial lift, and abandonment services.  The Alliance also develops technologies that provide efficient well construction, completion and abandonment options for deep and ultra-deepwater basins, high pressure, high temperature (HPHT) environments, as well as novel subsea well access, remediation, and intervention tooling for subsea production and processing systems. Added to these capabilities is a compliment of project managers with extensive intervention experience who apply collaborative contracting and scheduling to ensure operational efficiency.

 Positioning this range of expertise, services, and technologies as a single source enables the Subsea Services Alliance to provide integrated operational designs that maximize project safety while ensuring simpler and cost-effective subsea well intervention.

The Subsea Services Alliance combines the expertise and capabilities of Helix, OneSubsea and Schlumberger to provide a unique offering, integrating marine support with well access equipment and control technologies.  The Alliance is focused on increasing the operating envelope of today’s subsea intervention technology, which will offer clients an integrated approach to achieve simpler and more cost-effective intervention solutions.  Primary objectives include the expansion of applications enabled by subsea well-access technology, specific solutions for deep and ultra-deepwater basins and higher well pressure environments, and the evolution of Helix’s vessels to provide well intervention and additional support services such as well commissioning, artificial lift support, and abandonment, which are traditionally performed using drilling rigs.
