SLB
SLB has acquired RESMAN Energy Technology for an undisclosed amount.
RESMAN, headquartered in Norway with regional hubs in Houston and Abu Dhabi, is a global leader in advanced tracer technologies for wireless flow monitoring.
The company combines expertise in biotechnology, chemistry, physics, and petroleum engineering to offer solutions with parts-per-trillion detection limits and the longest tracer lifespan in the industry.
For nearly four decades, RESMAN has delivered intervention-free monitoring, enabling clients in oil and gas, CCUS, geothermal, and new energy segments to precisely understand fluid movement within reservoirs and wells.
This acquisition is a strategic move for SLB to enhance its portfolio of subsurface technology offerings.
RESMAN's specialized tracer solutions provide direct and uncontested evidence of fluid flow, which is crucial for optimizing production, improving reservoir management, and reducing operational risks.
Their robust technology, reflected in numerous patents and scientific publications, aligns with the growing industry demand for reliable and environmentally conscious monitoring tools.
Expected synergies include integrating RESMAN’s unique data acquisition capabilities with SLB’s extensive global reach and complementary service lines.
This will allow SLB to offer more comprehensive and precise insights into subsurface dynamics, supporting operational efficiency across a broader range of energy projects.
The combination is particularly relevant for complex well architectures and for developing sustainable solutions in emerging energy sectors like carbon capture, utilization, and storage (CCUS) and geothermal energy.
The combined entity is positioned to accelerate the adoption of advanced monitoring technologies, providing clients with enhanced tools for managing their energy assets.
This strategic integration aims to deliver increased value through improved reservoir understanding and optimized resource recovery, contributing to more efficient and sustainable energy operations globally.
