Onshore methane monitoring with Nubo Sentry

Cover more. Worry less.

 

Onshore oil and gas operations range from low-production, simple well sites to complex midstream facilities. Each comes with its own emission profiles and monitoring challenges. Nubo Sentry gives operators a practical and flexible way to address them all. By placing intrinsically safe sensors close to potential emission sources, operators gain precise spatial and temporal resolution, faster localization of leaks, and shorter time to root-cause analysis.

 

As part of Sensirion’s ecosystem of continuous monitoring solutions, a combination with Nubo Sphere fenceline monitoring or the Kuva camera, yields expanded coverage and maximized performance more cost-efficiently than deploying multiple standalone solutions.   Operators get a complete picture of emission profiles, high accuracy event detection, and faster identification of root causes. Together, the solutions empower operational excellence, improve safety, strengthen compliance, and reduce the overall cost of emissions management.

Cost-efficient monitoring for low-production wells

 

Smaller, simpler well sites require solutions that deliver value at low cost. Nubo Sentry meets this need by using just a few strategically placed sensor nodes to monitor key emission sources. Its low detection limit allows for fewer sensors without compromising performance.


Adding a wind sensor further enhances the system by distinguishing between on-site and off-site emissions and enabling quantification.


Deployment example of a simple upstream site:

  • 1 well head, 2 tanks

  • Deployment of 2 Nubo Sentry nodes plus 1 wind sensor

  • Local LoRaWAN gateway or existing third-party infrastructure for communications

Tailored to fit: optimized, scalable monitoring of more complex sites

 

At more complex upstream or midstream sites, our portfolio shines by offering flexibility and modularity. Operators can mix and match solutions to meet specific site needs. Use Nubo Sentry for targeted, close-proximity monitoring of high-interest areas—indoors or outdoors. Combine it strategically with Nubo Sphere for fenceline monitoring or Kuva cameras for visual confirmation of emissions. This integrated approach ensures optimized performance across emission sources that are hard to access or likely to emit, such as tank thief hatches, compressors (for load optimization), separators, housed structures while keeping costs in mind.

 

Together, these solutions improve the reliability and accuracy of methane detection, accelerate root-cause analysis, and reduce LDAR program costs. They also enhance site safety by enabling early detection of elevated methane levels in confined areas or indoors—complementing existing LEL sensors.

 

Deployment example of an intermediate upstream site:

  • 7 tanks, 4 separators, 1 compressor (among others)

  • Deployment of 4 Nubo Sphere sensor nodes in combination with 3 Nubo Sentry nodes for tank and separator monitoring

Monitoring inside enclosed spaces

Indoor areas require a different monitoring strategy. Nubo Sentry translates methane concentrations into emission rates by factoring in building volume and ventilation. This allows operators to detect methane build-up indoors with confidence and maintain safe operations.

Stationary LDAR and EU methane regulations

 

Traditional LDAR programs often miss intermittent emissions and require significant resources. Continuous monitoring solutions add a permanent layer of coverage, giving operators near real-time insight and faster response to methane emissions. Regulators are taking notice.

 

Our specialist articles provide guidance on what these regulations could mean for operators, how standards and work practices may be set, and the role Nubo Sentry and Nubo Sphere can play in compliance and emissions reduction goals. Click on the links below to find out more.
