Natural Gas Detectors and Alarms

The four common types are catalytic (combustible) sensors, infrared (optical) sensors, electrochemical sensors, and semiconductor/metal-oxide sensors. Each detects gas differently — infrared sensors, like the LWIR optical gas imaging used in Well Checked's systems, measure light absorption and are well-suited for continuous, non-contact methane detection over wide areas.

Infrared (NDIR) sensing is the primary technology used for natural gas and methane detection because it offers reliable, non-contact measurement unaffected by sensor poisoning. Well Checked's platform uses Long-Wave Infrared Optical Gas Imaging cameras, which visualize methane and VOC plumes in real time across an entire wellsite.

The platform's AI Site Learning function analyzes site-specific video, acoustic, and gas imaging data for approximately two days to establish a normal operational baseline. Once learned, the system alerts operators only on genuine deviations from that baseline, filtering out routine flaring, venting, or equipment noise that would otherwise trigger false alerts.

Zentinal Core™ is the first-line detection layer that identifies and validates true fugitive emission events while filtering out false alarms. Zentinal IQ™ builds on Core-validated events to quantify emission volume, rate, and duration with regulatory-defensible accuracy suitable for EPA, ESG, and state-agency submissions.

Yes. Both Zentinal Core™ and Zentinal IQ™ integrate with operator SCADA systems through a published, read-only API, alongside dashboard, email, and SMS/text alert channels, so detection events flow directly into existing operational and compliance workflows without disrupting cybersecurity requirements.

Yes. Well Checked offers both purchase and lease ownership options, along with a fixed-fee pilot program that lets operators evaluate the platform's detection accuracy and false-alarm elimination on a defined site count and duration before committing to a full-scale rollout.
