The Problem: Methane Leakage
When burned for energy, natural gas emits about half as much atmosphere-warming carbon dioxide (CO2) as coal, but there's a significant caveat. Methane, the main constituent of natural gas, is a greenhouse gas with more than 80 times the warming effect of CO2. As a result, if the production and transportation of natural gas result in more than a three-percent methane leakage rate, it becomes more environmentally damaging than coal.
Research suggests that the current methane leakage rate far exceeds the three-percent threshold. “We surveyed almost every oil and gas asset in the New Mexico Permian for an entire year to measure and link emissions to specific anonymized facilities,” said Evan Sherwin, co-author of a paper on methane leakage, to Stanford News. “It’s worse than we thought by a long shot." Sherwin’s team surveyed more than 26,000 gas wells over 16 months. They came up with a nine-percent methane leakage rate: about three times the threshold rate.

The Goal: Regulatory Compliance
Globally, natural gas enjoys a more positive public perception than other fossil fuels. Consumers support expanding the use of natural gas over coal and oil, and demand for natural gas is growing.
However, methane leakage poses a threat to the natural gas industry's growth prospects. Over 100 countries have committed to reducing methane emissions by 2030, and implementation plans include stringent regulations for natural gas production and delivery. In 2021, the White House unveiled an "Action Plan" that proposed new performance standards aimed at significantly cutting methane emissions. Furthermore, the 2021 Infrastructure Bill allocated $4.7 billion to cap abandoned gas wells, a first step toward enforcing these proposed standards. This situation presents an urgent challenge for stakeholders in natural gas production and delivery: they need to lower their methane leakage rates swiftly to avoid the financial impacts of impending regulatory measures.
The Solution: Machine Vision
Methane leakage not only harms the environment but also significantly impacts the financial viability of natural gas producers. On average, these businesses experience a loss of about nine percent of their product during processing, comparable to a fast-food restaurant dropping every tenth burger patty.
Addressing this issue requires prompt detection and repair of methane leaks. However, traditional methane leakage detection and repair systems (LDRSs) face a major challenge: methane is invisible to the human eye, necessitating the use of specialized hyperspectral instruments for detection. Conventional methods involve bulky, ground-based equipment, leading to a slow, limited, and error-prone detection process. Outsourcing to aerial equipment contractors is another option, but it's expensive and raises concerns about security and privacy.
Synaptiq and Hindsight Imaging Inc. have developed a better solution: machine vision software housed in compact hyperspectral hardware, less than a square foot in size, installed on-site. This hardware continuously captures hyperspectral images, which the machine vision software analyzes to identify signs of leaks.
This solution offers in autonomous, round-the-clock monitoring and reporting of methane leakage, significantly reducing costs. It also accumulates data over time, providing valuable insights like the cumulative product and profit loss, trends in methane leaks, and predictive analytics to forecast where and when methane leaks are most likely to happen in the future. It not only enhances efficiency but also aids strategic, proactive planning.
