SLB has signed a definitive agreement to acquire RESMAN Energy Technology, a global leader in wireless reservoir surveillance solutions, in a move aimed at strengthening its production and recovery portfolio.
RESMAN’s proprietary tracer technologies, already in use across oil, gas, CO₂ storage, and geothermal projects, allow operators to track fluid movement in reservoirs with precision down to parts per trillion. These insights enable faster interventions, extended well life, and optimized recovery while minimizing operational disruptions.
SLB said the acquisition will integrate RESMAN’s tracer expertise with its own subsurface knowledge, digital workflows, and production systems. The company expects the combined offering to provide operators with earlier detection of unwanted fluids, improved recovery outcomes, and enhanced monitoring of CO₂ storage sites under carbon capture initiatives.
Paul Sims, president of SLB Production Systems, noted that the addition of RESMAN technology will give customers “faster, more precise insights” for production optimization and reservoir management. RESMAN CEO Bonnie Powell emphasized that joining SLB will extend the company’s global reach while expanding the impact of its surveillance solutions.
The deal is subject to customary closing conditions and is expected to close in early 2026.
