Rapid Leak Detection in the Piceance Basin: How Qube Helped Catch A Separator Leak
Introduction
In Colorado’s Piceance Basin, a leading operator continues to set the bar for emissions control and operational safety. By integrating Qube Technologies’ continuous methane monitoring system, the operator aimed to strengthen its LDAR program and protect nearby homes located within 1,000 feet of its well pad.
This case study details how real-time alarms and accurate emissions source localization led to rapid action at the wellsite. Notably, catching a high-volume leak at the separator from going unnoticed over the weekend.

Challenge
On June 5th, 2025, Qube sensors deployed around the perimeter detected a sharp rise in methane levels – from practically zero to 1000 ppm – in under an hour. A conventional quarterly survey would not have revisited the pad for several weeks. Without real-time detection, the emissions event could have persisted all weekend, posing risks to nearby residents, safe operations, and environmental performance.
Qube’s Solution
Always-on Monitoring: Five Qube sensors continuously streamed methane and wind data from the site perimeter.
Automated alarms: Dashboard alarm notifications were emailed to operators when the dashboard detected the excessive emissions.
Accurate localization: Real-time Gaussian modeling converged on a separator as the source, providing precise coordinates for field crews.
Verification loop: After the operator shut in the well, Qube’s monitoring confirmed that methane levels returned to baseline.
Qube’s devices detected elevated emissions, localized to the separator and notified operators via automated alarms. Panel a) provides a dashboard view of the wellsite with a nearby residence. Panel b) includes photographs of the leak discovered by the field team after receiving the automated alarm notification.
Results
Upon arrival, the field team identified a washout on a gas line between the wellhead and the separator. Gas was venting directly near the Qube sensors. Thanks to the automated alarm, the operator shut in the well immediately, vented the lines, and safely began repairs. All while avoiding hours or days of uncontrolled emissions.
Most importantly, the operator averted extended methane release near a home just 1,000 feet from the pad. Qube’s system allowed the team to act fast and reinforce their reputation for a strong commitment to public safety and responsible operations.
Takeaway for Operators
Operate confidently in proximity to communities with continuous monitoring that flags and localizes emissions in real time.
