SLB, a leading technology company in the energy sector, has signed a definitive agreement to acquire RESMAN Energy Technology, a specialist in wireless reservoir surveillance solutions. The acquisition, expected to close in early 2026 pending regulatory approvals, strengthens SLB’s offerings in reservoir monitoring and production optimization.

RESMAN’s advanced chemical tracer systems enable operators to track the movement of water, gas, oil, and CO₂ in reservoirs with parts-per-trillion precision, providing detailed insights into well performance and reservoir behavior without production interruptions. Such capabilities are vital in oil and gas as well as in emerging sectors like CO₂ storage and geothermal energy.

The tracers, which can be embedded in completion equipment at the sand face, allow pinpointing of zones producing unwanted fluids. This information facilitates targeted interventions to extend well life and optimize recovery.

Paul Sims, SLB’s president of Production Systems, said, “With RESMAN’s industry-leading tracer technology, we are expanding our ability to deliver end-to-end solutions for reservoir monitoring and production optimization.” He highlighted the synergy between RESMAN’s tracer technology and SLB’s expertise in sampling, analysis, and digital workflows, enabling customers to gain faster, more precise insights and make smarter, data-driven decisions. The combined capabilities are designed to maximize asset performance across traditional oil and gas operations and emerging energy transition applications.

This acquisition follows SLB’s 2024 $7.75 billion all-stock deal to acquire ChampionX, a U.S.-based company specializing in production chemicals and artificial lift technologies, in 2024. That move aimed to bolster SLB’s production optimization capacities and secure more stable revenue streams beyond drilling services.
