Methane Gas Detection for Oil & Gas

The two broad categories are fixed and portable gas detection equipment. Fixed detectors are installed at a location for continuous monitoring and alarm notification, making them useful for wellsites, tanks, compressors, and processing equipment. Portable detectors are handheld or wearable instruments used by personnel for spot checks, confined-space work, and personal exposure monitoring. A comprehensive program may use both.

A reading of 3% LEL means the detector has measured gas at 3% of its lower explosive limit, the minimum concentration at which a flammable gas can ignite in air. It is not 3% gas concentration by volume. The reading indicates an early combustible-gas presence and should trigger the site’s established safety, investigation, and response procedures.

Continuous methane detection uses permanently deployed sensors to observe a site around the clock. Well Checked combines long-wave infrared optical gas imaging, video, and acoustic sensing with AI-assisted validation. The platform learns site conditions, compares sensor inputs, and flags suspected fugitive anomalies rather than relying on occasional inspections. Validated events can be sent through dashboard, email, text, and SCADA alert workflows.

Yes. Differentiating normal process activity from a fugitive emission is central to an effective monitoring program. Zentinal Core uses multiple sensor streams and site-specific learning to filter known non-fugitive events and reduce false alarms. The approximate two-day AI Site Learning cycle establishes a site baseline, while alert tuning can refine sensitivity and escalation rules as operating conditions evolve.

Long-wave infrared optical gas imaging provides visual detection capability for methane and VOC emissions in day or night conditions. Within a multi-sensor approach, it adds evidence that can be reviewed alongside video and acoustic signals. Well Checked’s long-wave infrared approach is designed to provide this persistent monitoring capability at approximately one-third the cost of traditional mid-wave infrared solutions.

Well Checked provides operator-facing workflow templates, dispatch runbooks, and rapid-response protocols for Zensory.ai deployments. Once a fugitive gas event is validated, designated dispatch teams can receive near-real-time alerts through the dashboard, email, text, or SCADA. The workflow is designed to support acknowledgement, dispatch, and mitigation within 24 hours, helping operators prioritize time-sensitive events.

The platform’s data output supports alternative-monitoring compliance submissions under EPA methane rule 40 CFR Part 60 Subpart OOOOb. Zentinal IQ quantifies emissions after Zentinal Core validates an event, helping create defensible records of emission duration and volume. Data is also structured to support OGMP 2.0 Level 4/5 measurement-based reporting and SASB Oil and Gas E&P and TCFD disclosure frameworks.

Well Checked serves continental US onshore upstream oil and gas producing regions. Confirmed experience includes a continuous monitoring deployment in the Appalachian Basin, with availability in the Permian, Anadarko, Bakken, Eagle Ford, Denver-Julesburg, and San Juan basins. Because the platform uses autonomous edge monitoring, it is well suited to geographically distributed remote wellsite portfolios.
