WellSense, a FrontRow Energy Technology Group company specializing in rapid fiber-optic well diagnostics, has sold a global license for its FiberLine Intervention (FLI) technology to Halliburton in a landmark transaction. The deal marks the first technology divestment by WellSense and its parent group.
Under the agreement, Halliburton will deploy FLI for well stimulation monitoring worldwide. WellSense will continue to apply the technology in other oil and gas applications, including plug and abandonment, well integrity and leak detection, and carbon capture, utilization and storage (CCUS).
“Completion of this deal is a defining moment for WellSense and for FrontRow,” said Annabel Green, CEO of WellSense. “It validates our innovation model and highlights the industry’s need for efficient, high-quality well diagnostics.”
Developed since 2015 and commercialized in 2018, FLI uses bare fiber despooling technology to deliver high-resolution subsurface data with disposable probes, offering operators efficiency gains and reduced risk compared with traditional monitoring methods.
For FrontRow, the transaction represents its first commercial license sale since the group was formed in 2016. “This deal demonstrates how UK-born innovation can address global industry challenges and create real commercial value,” said Steve Kent, CEO of FrontRow.
FrontRow’s portfolio also includes Unity, DTI and ClearWELL, with a focus on production and decommissioning solutions across the upstream energy sector.
