What Resman Energy Technology does

RESMAN Energy Technology, founded in 2005 and headquartered in Trondheim, Norway, develops and deploys wireless chemical tracer solutions for reservoir surveillance across oil and gas, carbon capture and storage (CCUS), and geothermal applications. The company's core technology uses proprietary chemical tracers to detect substances at parts-per-trillion levels without disrupting well operations, eliminating the need for downhole electrical components or wireline intervention. Its product portfolio is organized into three lines—RESMAN Production for inflow monitoring and flow profiling, RESMAN Reservoir for inter-well connectivity and sweep-efficiency mapping, and RESMAN New Energy for CCUS and geothermal characterization—together with the RESTRACK Client Portal, a Microsoft Azure-hosted digital platform launched in 2024.

The company operates an enterprise field-sales go-to-market model with regional offices in Trondheim, Sugar Land (Texas), Abu Dhabi, Stavanger, Aberdeenshire, and Kuala Lumpur, supporting more than 170 clients across 62 countries. Revenue is generated through the sale and deployment of tracer systems, laboratory analysis services, and digital workflow subscriptions, with custom pricing negotiated directly with operators. Major customers include the operators of the Snorre, Ekofisk, K12-B, In Salah, and Abu Dhabi offshore fields, as well as the Utah FORGE geothermal project. The company maintains a tracer database accumulated since 1986 containing more than 500,000 unique data points, which it cites as a key competitive asset for interpreting flow behavior across reservoirs.

In September 2025, SLB announced a definitive agreement to acquire RESMAN from Nordic Capital, completing the transaction in January 2026. Post-acquisition, RESMAN operates as a wholly-owned subsidiary of SLB (NYSE: SLB), integrating its tracer capabilities into SLB's established reservoir sampling, analysis, and digital workflow offerings. Prior to the acquisition, RESMAN held ISO certification, was certified as a Great Place to Work in 2024, and was named a finalist at the Reuters Global Energy Transition Awards.

Core offering

RESMAN Energy Technology develops and deploys proprietary chemical tracer technology for wireless reservoir surveillance across the oil and gas, carbon capture (CCUS), and geothermal sectors. The company provides three core product lines — RESMAN Production for inflow monitoring and flow profiling, RESMAN Reservoir for inter-well and saturation mapping, and RESMAN New Energy for CCUS and geothermal applications — all powered by parts-per-trillion chemical detection and delivered alongside its RESTRACK client portal for data management.

Product overview

RESMAN Energy Technology offers a unified portfolio of wireless reservoir surveillance and tracer solutions organized into three core product lines: RESMAN® Production for production well insight and flow profiling, RESMAN® Reservoir for reservoir modeling and sweep efficiency evaluation, and RESMAN® New Energy for CCUS and geothermal applications. All three product lines are powered by the company's proprietary chemical tracer technology capable of detecting substances at parts per trillion levels without disrupting well operations. The RESTRACK Client Portal serves as the digital platform enabling data access and analysis across all solutions. The company was acquired by SLB in January 2026.
