Global technology company SLB announced a definitive agreement for SLB to acquire RESMAN Energy Technology, a global leader in wireless reservoir surveillance solutions. RESMAN’s advanced chemical tracers provide unmatched precision and accuracy in tracking water, gas, oil and CO2 movement within reservoirs and wells, delivering critical insights to optimize production and recovery.

RESMAN’s cutting-edge tracer technology enables operators to monitor reservoir flow without disruption, offering unparalleled accuracy at parts per trillion (ppt) detection levels. These insights are vital for well performance and reservoir monitoring across oil and gas, CO2 storage and geothermal applications, helping operators enhance production and improve recovery.

Production tracers can be integrated with completion equipment at the sand face to identify zones producing unwanted fluids. This helps operators plan more effective interventions, extend well life and optimize production.

Users of tracers will continue to have the flexibility to select the vendor of their choice for the completion hardware.

“With RESMAN’s industry-leading tracer technology, we are expanding our ability to deliver end-to-end solutions for reservoir monitoring and production optimization,” said Paul Sims, president, Production Systems, SLB. “By combining RESMAN technology with SLB’s expertise in sampling & analysis, advanced digital workflows, and nearly a century of subsurface knowledge, customers will benefit from faster, more precise insights to make smarter, data-driven decisions. Together, these capabilities deliver unparalleled reservoir understanding, enabling operators to optimize production, enhance recovery, and maximize asset performance across both traditional oil and gas operations and emerging energy transition applications.”

“We are immensely proud of our technology and the unique value it brings to this rapidly evolving industry,” said Bonnie Powell, chief executive officer, RESMAN Energy Technology. “As part of SLB, we will expand our global reach and combine with their comprehensive portfolio of production and reservoir solutions to deliver even greater value to our customers.”

The transaction is subject to certain closing conditions and is expected to close in early 2026.
