For continuous monitoring, Probability of Detection (PoD) can be framed as a function of time. Detection confidence grows with each measurement window. Here we explain how controlled-release testing and time segmentation translate PoD into Time-to-Detection (TtD) and contrast that with single-pass survey methods. For operators, this provides a practical way to set expectations for how quickly a continuous system will find different-sized events and why that matters for response.

Most LDAR methods capture only a snapshot, so they miss when an event starts, when it ends, and how long it lasts. Without that timeline, it can be challenging to quantify released volume, verify repairs, or determine whether the source is constant, intermittent, or tied to specific operations. Qube’s continuous monitoring provides 24/7 data that time-bounds emission events, enabling accurate volume estimates and confident repair verification.

A Colorado well pad restarted after a non-routine shut-in. Within hours, Qube’s continuous monitoring flagged methane levels consistent with a large release event (estimated at >100 kg/h, about 125 mscf/d). The operator’s LDAR team located badly leaking level controllers and multiple thief hatches and completed repairs in under 24 hours. The operator then initiated a fleet-wide replacement of aging controllers to prevent recurrence.

At a Colorado wellsite, Qube’s continuous monitoring system alerted operators to a sustained emission event. Qube’s data localized the emissions to the tank area and prompted a field investigation to verify the source of the anomaly. With this information, the team was able to identify the emission source and interrogate the root cause, a blocked vent line leading to the combustor.

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.

A Colorado operator using Qube’s continuous methane monitoring system received an automated alert about an unexpected emissions spike at a wellhead. Upon investigation, the field team discovered the source: a cow had rubbed against the equipment and opened a manual ball valve, unintentionally releasing gas. The team quickly shut the valve, restored normal readings, and installed fencing to prevent similar incidents. Thanks to Qube’s real-time alerts, the issue was resolved within an hour—without downtime or emissions escalation.

“Another Win for Continuous Monitoring”

-Air Compliance Manager-QB Energy

Missed by AVO, caught by continuous monitoring. When Qube Technologies flagged elevated methane at a QB Energy tank site, field teams were able to locate and fix a leaking thief hatch—achieving a 97% emissions drop in hours. This case study shows how real-time continuous monitoring data and a fast response can keep operations running smooth.

Qube Technologies’ continuous emissions monitoring solutions provide operators with the tools to differentiate offsite from onsite emissions. Furthermore, our data modeling and intuitive dashboard omit those outside emissions from your facility total.

Methane management has emerged as a strategic priority for oil and gas operators. As regulatory frameworks evolve and investor expectations sharpen, reliance on periodic leak detection methods is no longer sufficient.

This straightforward application of continuous monitoring technology delivers actionable operational intelligence while enhancing environmental protection efforts.

Qube Technologies’ continuous emissions monitoring solutions provide operators with the tools to detect and respond to emissions trends before they become super emitter events. By configuring real-time alarms, operators can take corrective action immediately, preventing third-party reports and ensuring regulatory compliance.
