Introducing Score’s new MIDAS® Sensor Solution

Helping eliminate methane emissions at source using fixed, wireless acoustic sensor technology.

“Emissions from flares, vents, and drains account for a significant portion of global greenhouse gas emissions. Flaring alone contributes roughly 2.2 gigatons of CO₂ equivalent annually, representing over 30% of direct methane emissions from oil and gas operations worldwide. Efforts are underway to address these emissions through increased monitoring and reduction technologies” according to the Global Flaring and Methane Reduction Partnership (GFMR)[1]. Score has developed innovative technology to help operators detect and eliminate these emissions quickly and effectively.

While new regulations in many regions have helped to eliminate most intended flaring and venting, the next challenge lies in tackling unintended methane releases. These are harder to detect, trace, and control, and are often overlooked.

According to World Bank data, one North Sea platform flared 12 million m³ of methane, equating to $1.38 million in lost sales. Globally, the figure rises to 138,549 million m³, or $16 billion in equivalent sales value. The environmental and financial impact of capturing this lost gas is massive[2].

Currently, emissions monitoring data is collected at the flare or vent stack i.e. the point of atmospheric release, not at the source of the emissions. Addressing emissions at the flare is like treating the effects of an illness without ever diagnosing its cause, which is likely to persist and perhaps even worsen, if not properly addressed.

To truly eliminate emissions, operators must move beyond detection and quantification at the flare, towards finding the source (the root cause) and act fast to eliminate from there.

Studies show that faulty process isolating valves are the leading source of unintended methane emissions. These valves are supposed to block methane from reaching the flare or vent but often don’t. So long as these leaking valves remain undetected, emissions accumulate, and so do potential costs, losses and environmental impacts.

Identifying the specific leaking valve in manifold systems can be especially challenging. Many valves can be connected to a single flare or vent system, making it impossible to know where to act, based on stack measurements alone.

Two key metrics define success:

• Mean Time to Detection (MTTD); how quickly a leak source is identified.
• Mean Time to Repair (MTTR); how quickly the leak is mitigated / eliminated.

Our solution is the new non-invasive MIDAS® Sensor technology, permanently installed on each valve within the flare or vent system. These sensors can:

• Instantly detect and quantify valve leaks.
• Send real-time data to operations teams.
• Enable immediate prioritisation and targeting of maintenance.
• Minimise environmental impacts and support sustainability.
• Optimise operational safety, efficiency and profits.

This approach helps minimise MTTD and MTTR, reducing overall emissions, while avoiding unnecessary preventative maintenance, and improving maintenance return on investment (ROI). By detecting and fixing only what's leaking, companies act faster and smarter.

In summary, rapid detection and response are critical in methane emissions management. With the right tools and approach, operators can meet regulatory demands, protect the environment, and pave the way for a cleaner, more sustainable future.
