50% Methane Reduction Achieved—SENSIT FMD Delivers Real-Time Alerts and Pinpoint Leak Detection for Smarter, Faster Action.
At one of California’s largest oil fields, operators deployed SENSIT’s TDLAS laser-based FMD for continuous methane surveillance across a 100-acre well pad. Using a network of remote solar-powered FMDs, the team monitored site-wide emissions with a detection threshold as low as 200ppb, providing real-time alerts and high-resolution leak localization. Over the 18-month deployment, average daily methane levels dropped from 4 ppm to 2.2 ppm, with maximum readings falling by over 80%.
The FMD system enabled site-specific tuning by adjusting leak alert thresholds over time, reducing false positives and streamlining response workflows. Once large leaks were addressed, the platform successfully revealed smaller, harder-to-detect emissions—including sporadic leaks tied to specific equipment that only became noticeable at night. By integrating FMD data with handheld laser (LZ30) and sniffer (Gold G3) tools, operators achieved over 90% success in pinpointing and mitigating emissions.
Validated in both real-world and blind controlled-release tests, the SENSIT FMD demonstrated 72% true positive detection and 90% localization accuracy—well below the EPA’s super-emitter threshold. Its ability to operate maintenance-free for extended periods and adapt to complex site conditions makes it a powerful tool for emissions reduction. This deployment highlights the FMD as a cornerstone in scalable, tiered methane mitigation strategies.
