WellSen

WellSen is a UK-based oilfield technology company that provides low-cost, deployable downhole fiber-optic distributed sensing solutions for the oil and gas industry. Its flagship Fli Dynamic De-Spool probe enables single-engineer deployment of bare optical fiber into static wells without wireline or winch equipment, delivering continuous full-well coverage for leak detection, cement assurance, and injection profiling. The system reduces survey time by up to 80% compared to traditional wireline methods and is designed for high-volume, repeatable well diagnostic programs including pre-plugging and abandonment surveys.
