SLB unlocks $85bn tech edge for North Sea’s largest oil field
Equinor awards SLB real-time leak detection and digital monitoring for Johan Sverdrup Phase 3 expansion
SLB has been awarded a contract by Equinor to expand real-time leak detection and digital production monitoring for the Johan Sverdrup Phase 3 development in the North Sea, one of the world’s largest offshore oil fields. The deal will see SLB deploy its Olga Online production management system across new subsea infrastructure, enhancing operational visibility and asset integrity for Equinor’s most strategically significant producing asset.
SLB’s Olga Online system, which combines first-principles multiphase flow modelling with real-time analytics, will provide continuous surveillance of wells, pipelines, and subsea infrastructure, offering early detection of leaks and insights into their size, location, and severity.
How Olga Online transforms offshore production monitoring: North Sea
The Olga Online system is not new to Johan Sverdrup. It was successfully deployed during the field’s Phase 2 development, where it supported leak detection and real-time production surveillance across the existing production network. The Phase 3 award builds on this track record, extending the system’s reach to include the new infrastructure associated with the latest expansion.

For Equinor, the benefits are clear. The system’s real-time analytics will strengthen operational reliability, support safe operations, and optimise production performance throughout the field’s lifecycle.
The system integrates real-time data from sensors across subsea infrastructure, using advanced algorithms to simulate fluid behaviour under varying conditions. This allows operators to detect anomalies, such as pressure drops or flow irregularities, that may indicate leaks or equipment failures before they escalate into costly incidents.
SLB, a US-based energy technology company with a market capitalisation of $85.1 billion, will handle the delivery, commissioning, and long-term operation of the system. SLB’s role as a long-term partner underscores its position as a leader in digital energy solutions, with a portfolio that spans traditional oil and gas services to emerging low-carbon technologies.
SLB’s broader push into digital energy solutions
Johan Sverdrup contract is part of SLB’s broader strategy to expand its digital and automation-led services. The company has also been selected as the strategic reservoir partner for the Havstjerne carbon storage project in the Norwegian North Sea, which focuses on offshore storage for European industrial emitters.
SLB’s involvement includes subsurface studies, the design of subsea injection systems, and monitoring frameworks to ensure the safe and efficient storage of captured CO₂.
In addition to its carbon storage initiatives, SLB has launched the ExaCT electrical downhole coiled tubing control system, which delivers real-time electrical control for downhole interventions. The ExaCT system enables precise control of downhole tools, reducing intervention time and improving recovery rates in mature fields.
Johan Sverdrup Phase 3 deployment, in particular, highlights how real-time monitoring can enhance asset integrity in complex offshore environments, where even minor leaks can have significant financial and environmental consequences. As operators face increasing regulatory and investor pressure to decarbonise, technologies like Olga Online and ExaCT are becoming essential tools for balancing production demands with sustainability goals.
The expansion of SLB’s Olga Online system at Johan Sverdrup Phase 3 sets a new benchmark for digital monitoring in offshore oil and gas. The project demonstrates how real-time data analytics can transform asset management, reducing operational risks and improving recovery rates. For Equinor, the benefits extend beyond immediate leak detection, Olga Online provides a platform for continuous optimisation, allowing engineers to fine-tune production parameters based on live data.
Industry analysts have noted that the adoption of such systems could become a competitive differentiator for operators in mature basins like the North Sea. Fields like Johan Sverdrup, which are critical to Europe’s energy security, require robust monitoring solutions to maintain production levels while minimising environmental risks. SLB’s technology addresses this need by offering a scalable, cloud-based platform that can be adapted to fields of varying complexity.
The Havstjerne carbon storage project further illustrates SLB’s role in shaping the future of energy. As European industrial emitters seek viable pathways to net-zero, offshore carbon storage presents a scalable solution. Norway’s regulatory framework, which incentivises CCS projects, has positioned the country as a leader in this space. SLB’s subsurface expertise is critical to the success of such projects, ensuring that storage sites are geologically sound and capable of securely containing CO₂ for decades.
For stakeholders in the energy sector, these developments underscore the importance of digital transformation. Operators that invest in real-time monitoring and automation technologies are better positioned to navigate the dual challenges of maintaining production efficiency and meeting sustainability targets. SLB’s portfolio, spanning digital production systems, carbon storage, and downhole intervention tools, reflects this evolving landscape, where technology and energy transition go hand in hand.
Looking ahead, the integration of digital monitoring systems like Olga Online is expected to become standard practice in offshore oil and gas operations. As the industry faces growing pressure to reduce emissions and improve safety, technologies that enhance operational transparency and reliability will play a crucial role in shaping the future of energy production. For companies like Equinor and SLB, the Johan Sverdrup Phase 3 deployment is not just a contract, it is a blueprint for the next generation of offshore energy infrastructure.
Operators and investors seeking to stay ahead of industry trends can follow updates on SLB’s digital energy solutions through the company’s official channels, including its corporate website and investor relations portal. Equinor’s progress on the Johan Sverdrup and Havstjerne projects is also publicly available via its official reports and sustainability disclosures.
