WellSense, a specialist in fibre optic well diagnostics, will demonstrate the results from its successful field trial of its new well conveyance technology at ADIPEC
Developed at WellSense’s UK headquarters and R&D hub in Aberdeen, the FiberLine Intervention Conveyance System (FliCS) well conveyance technology, designed to improve the speed, quality, cost and efficiency of diagnostic surveys in horizontal wells, is able to rapidly deploy bare fibre into highly deviated wells.
WellSense successfully completed a technology field trial for a major international operator in August 2025, where the single-use, jet-propelled and battery powered system deployed bare fibre into a 19,000 foot uncompleted well in the Permian Basin for cross well strain monitoring. The deployment took just 50 minutes, around 10 times faster than a standard pumpdown operation. The prototype model deploys 25,000 feet of fibre in little over an hour, travelling around ~350ft./min. versus ~35 ft./min. for a conventional tractor conveyance. The lightweight components can be left in the toe of the well or pushed to the bottom. The new well access solution introduces the ability to deploy Fli into horizontal wells to acquire distributed acoustic sensing and distributed temperature sensing data across the reservoir.
The operator has confirmed its intention to redeploy the technology in four further projects over the next three months.
In the Middle East, the technology promises to provide valuable diagnostics for matrix acid stimulation, an approach widely used to improve carbonate rock matrix permeability and flow channels, so improved knowledge of fluid placement can enhance treatment and diretly improve well performance.
Annabel Green, CEO at WellSense, said, “FliCS will provide well operators a cost-effective, low risk well surveillance solution for horizontal wells for the first time. While it will have many applications in well integrity, it also enables a major expansion of injection profiling capabilities. This has global application, providing performance data to enable water injection to be optimised for effective pressure support and oil displacement."
WellSense is looking to deliver its first, multi-unit, prototype order while developing a slimmer model for deployment through smaller tubing, with a view to commercial launch early next year. It is looking to actively engage with customers at ADIPEC and beyond to discuss opportunities.
