Offshore Reservoir Stimulation Vessel Upgrades for Tight Field Recovery

SLB and Equinor have entered into a multi-year agreement to deploy advanced reservoir stimulation services across the Norwegian Continental Shelf. The collaboration centers on converting and upgrading an offshore stimulation vessel to enable high-intensity treatments in tight reservoir developments.

Industrial Challenge and Operational Context
Developing tight offshore formations requires specialized hydraulic fracturing and proppant delivery capabilities to enhance rock permeability and maximize well recovery. Operating in offshore energy infrastructure environments requires high material storage capacity, precise automated blending systems, and high-pressure pumping equipment integrated into marine vessel architecture. Equinor as the operator and SLB as the service provider are combining operational planning and technical expertise to secure dedicated offshore stimulation capacity.

Vessel Upgrades and Technical Architecture
Under the agreement, the well stimulation vessel MV Island Captain is undergoing a major technical conversion into a proppant-capable stimulation vessel. The architectural modifications include expanding proppant storage capacity up to two million pounds, installing automated proppant handling and blending systems, and integrating higher-capacity high-pressure pumping units. The vessel deck layout is optimized to manage continuous material flow and support complex stimulation operations.

Deployment and Operational Role
The upgraded vessel will operate across the Norwegian Continental Shelf, providing dedicated stimulation services tailored to low-permeability geological structures. SLB manages the technical conversion, equipment integration, and field operations. Equinor integrates the vessel capacity into its long-term field development schedule to secure operational continuity and mitigate logistics risks across future offshore well operations.

Application and Technical Impact
High-intensity proppant injection increases hydraulic fracture conductivity in tight formations. Securing dedicated, high-capacity offshore stimulation vessels ensures repeatable treatment execution, maintains process stability during complex pumping operations, and supports long-term resource recovery.

"The upgrade of the Island Captain represents an important investment in offshore stimulation capability for the Norwegian Continental Shelf," said Ole Christian Meldahl, managing director, Scandinavia, SLB. "Together, this dedicated capacity and specialized equipment will help support future reservoir developments across the region."
