Qube won EPA approval in March 2025 as an alternative test method for methane periodic screening, letting operators use continuous monitoring instead of or alongside OGI surveys.

This paper lays out why continuous monitoring beats periodic inspections, pointing to faster leak detection, methane cuts of up to 95 percent, and lower compliance costs.

An SPE-presented study testing continuous monitoring against conventional LDAR in Alberta found it could roughly double emissions reductions versus standard inspection programs.

A two-year field test found Qube's sensors held accuracy within 1 PPM, with an auto-baselining algorithm correcting for drift without manual recalibration.

A Permian Basin operator cut its response time to leaks from 91 days down to under 24 hours, and monthly methane emissions dropped 79 percent over a year.

A field pilot of 52 devices across 16 Alberta facilities showed continuous monitoring catching leaks in days rather than waiting for annual inspections, cutting some sites' emissions by 60 percent.

Independent controlled-release testing by Highwood Emissions Management measured how reliably Qube's devices detect leaks at varying distances, wind speeds, and release rates.

With EPA's Super Emitter Program now naming operators publicly for large releases, this paper shows how continuous monitoring helped customers cut average emission rates and super-emitter events by up to 90 percent.
