A facility's flare was reading normal tip temperature, but continuous monitoring showed emissions climbing month over month. Here's how cross-referencing monitoring data with operational records traced the issue to a blower running without PID control.

When Qube's continuous monitoring system detected elevated emissions around a BTEX system, the combustor was the obvious suspect. By analysing emission patterns across different control valve configurations, the team used the monitoring data to work through a structured diagnosis. The right repair was made, emissions returned below baseline, and the operator avoided unnecessary capex on equipment the data had already cleared.

See how operators are using Qube’s continuous emissions monitoring to investigate equipment issues, confirm repairs, and reduce unnecessary site visits. Real-world case studies demonstrate the measurable value of pairing emissions data with operational context — across cost reduction, site performance, and emissions management.

When potential methane sources are located close together, how do you know which unit is actually emitting?

This case study shows how Qube Lite, our new intrinsically safe methane sensor, helps operators distinguish emission source from a single tank at a tank farm.

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”

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.

Qube Technologies has built the Controlled Release Test Facility (CRTF), roughly 60 km (~ 37 mi) west of Calgary, Alberta, which functions as a specialized field environment to conduct continuous monitoring (CM) emissions tests under controlled real-world conditions. 

Qube’s platform provides continuous emissions monitoring, using wind data, gas concentration, and source identification algorithms to detect methane leaks. However, users must verify alerts, as the algorithm benefits from operational input to ensure accurate source identification. 

By upgrading high-bleed pneumatic devices to low-bleed controllers and implementing robust monitoring programs, operators can achieve significant reductions in methane emissions. These proactive measures are essential for complying with evolving regulations and minimizing environmental impact. 

This study reinforces a core value proposition of the Qube platform: minimal sensing hardware is required to accurately quantify methane emissions, and the devices remain reliable year after year in the field without manual intervention. 

Qube deployed continuous monitoring devices with CH4 and CO sensors throughout a customer’s natural gas processing facility. The Qube sensors detected elevated emissions – specifically, increased CO concentrations – and reported this data to the customer via Qube’s dashboard.

Emissions from oil and gas facilities are dynamic and often intermittent, meaning that standard measurement techniques may only capture a small portion of a facility's actual emissions. This is commonly known as intermittency, referring to the sporadic release of gases caused by operational changes or equipment issues.

This pilot showed that leaks do not occur at consistent intervals or emission rates. In fact, just 5% of the detected leaks represented ~55% of the total emissions over nine months of data collection. This distribution is similar to the oil and gas sector, where research has found that the top 5-10% of leaks represent 60-80% of emissions.

Continuous monitoring technologies allow operators to implement novel operation and maintenance work practices to efficiently respond to methane emissions

One of the largest power producers in Indonesia implemented Qube‘s continuous monitoring solution to monitor for H2S gas at a new geothermal facility.
