SLB is now set to acquire Houston-based reservoir technology company Tachyus in a move aimed at strengthening its digital oilfield capabilities and expanding its portfolio of data-driven reservoir management tools.
The acquisition, for an undisclosed sum, reflects growing industry demand for software that enables faster and more adaptive decision-making across complex oil and gas operations.
Tachyus develops advanced reservoir modelling and optimisation platforms that combine machine learning with physics-based modelling to evaluate asset performance under changing operational conditions.
At the centre of Tachyus’ offering is its Aqueon platform, which has been deployed across more than 7,500 wells globally.
The software supports a wide range of reservoir management functions, including waterflood optimisation, production forecasting, pressure management, saltwater disposal and enhanced oil recovery.
Its capabilities allow operators to continuously adjust field strategies based on real-time data insights.
SLB plans to integrate Tachyus’ applications into its Delfi digital platform and Lumi data and artificial intelligence environment, creating more unified workflows across reservoir and production management.
The company expects this integration to improve operational visibility and enable faster scenario analysis, allowing technical teams to adapt development plans within minutes as field conditions evolve.
The transaction also brings additional expertise in reservoir engineering, data science and software development to SLB’s digital division.
This aligns with the company’s broader strategy of expanding its digital offerings to support both short-term operational performance and long-term asset optimisation.
Industry trends indicate that operators are increasingly focused on maximising recovery from existing assets rather than pursuing new exploration.
As reservoirs mature and become more complex, continuous reservoir management supported by advanced analytics is becoming a critical component of operational strategy.
SLB believes the addition of Tachyus will enhance its ability to deliver integrated workflows that address these challenges, particularly in enhanced oil recovery projects.
Founded in 2014, Tachyus has positioned itself as a specialist in operational optimisation.
Its proprietary Data Physics engine underpins the Aqueon platform, which the company reports has helped clients increase production, reduce costs and lower greenhouse gas emissions.
The platform has also expanded into carbon-focused applications, including modelling for carbon dioxide enhanced oil recovery, which is already being used by major operators in the United States.
Tachyus has also entered the environmental, social and governance segment with its Aurion software, launched in 2022.
Aurion enables companies to estimate, forecast and report greenhouse gas emissions, and has secured more than 20 clients across the United States, the Middle East and Latin America.
The acquisition comes as SLB continues to invest in digital transformation amid mixed financial performance.
For the first quarter of 2026, the company reported net income of US$752 million, down 6 per cent from the previous year, while revenue rose 3 per cent to US$8.72 billion.
The company has also recently expanded its partnership with Vår Energi, with the Delfi platform set to support field development planning on the Norwegian Continental Shelf.
Completion of the Tachyus transaction is expected shortly, subject to customary closing conditions.
