Continuous methane monitoring for small oil and gas operators.
Cairn Sensing places solar and battery-powered sensors at wellsites, compressors, tank batteries and storage, so you know about a leak before a survey, a satellite or a regulator does.
Free 90-day pilot. No cost, no long-term commitment.
Periodic surveys leave long gaps, and others are watching
Most small operators find leaks during scheduled surveys. Between them, a stuck dump valve, an open thief hatch or a failed seal on a compressor can vent for weeks.
EPA’s methane rules for new and existing sources (OOOOb and OOOOc) allow continuous monitoring as an alternative approach to some periodic surveys, and include a super-emitter program in which approved third parties can report large releases they detect. Federal methane fee rules have been changing too. Whatever form the rules take, a record of your own emissions puts you ahead of the people looking from outside.
How Cairn fits
- Near-equipment sensingUnits near compressors, separators, tanks and wellheads catch leaks where they start.
- Fence-line sensingBoundary sensors show what’s leaving the pad or the station.
- Your own recordIf a third party reports a release, you have the readings for that day.
- Remote-readySolar and battery-powered, reporting over cellular with satellite fallback for sites with no signal.
- Alerts at your thresholdGet notified when readings cross the level you choose.
How a pilot works
We start with a 15-minute call about your site, what you monitor today and where readings come from.
If it’s a fit, we install a small number of sensors and run them for 90 days at no cost. You get the alerts and the data, and at the end you decide whether it’s worth keeping.
Cairn isn’t currently an EPA-approved alternative test method. A pilot shows what continuous data looks like on your sites and whether it’s worth building on.
