What Resman does
Resman (legal entity RESMAN AS) is a Norway-headquartered oil and gas services company founded in 2005 that develops and deploys proprietary chemical and biological tracer technology for reservoir fluid monitoring. Its products quantify the movement of oil, gas, water, and CO2 in subsurface reservoirs without requiring well interventions, differentiated by parts-per-trillion detection limits and the longest tracer lifespan in the industry. The product portfolio is organized into three solution areas, RESMAN Production, RESMAN Reservoir, and RESMAN New Energy (covering CCUS and geothermal applications), supplemented by RESTRACK, a Microsoft Azure-hosted client portal for tracer data management and analytics.
The company serves enterprise oil and gas operators as its primary customer segment and is expanding into emerging-energy segments such as carbon capture, utilization and storage (CCUS) and geothermal. Its commercial model is enterprise field sales with custom, quote-based pricing and multi-year service contracts, supported by regional offices in the United States, Brazil, the United Arab Emirates, and Malaysia in addition to the Ranheim, Norway headquarters. Over 50% of employees hold advanced degrees in biotechnology, physics, chemistry, or petroleum engineering, and the company operates a biotech-grade scientific laboratory in Norway.
On 14 January 2026 SLB (Schlumberger) completed the acquisition of RESMAN Energy Technology, integrating the tracer technology into SLB's global oilfield services portfolio. Following the transaction, RESMAN continues to operate as a subsidiary of SLB with expanded access to global distribution, resources, and enterprise customers.
