(Drones for oil and gas industry)
Oil and gas companies face mounting pressure to cut methane emissions by over 30% from 2020 levels by 2030 under the Global Methane Pledge. Moreover, the U.S. EPA’s New Source Performance Standards mandate frequent Leak Detection and Repair (LDAR) surveys to comply with strict emission limits. Consequently, operators must adopt innovative monitoring methods that meet regulatory deadlines and support their climate goals.
Beyond regulations, traditional on-site leak detection exposes technicians to high-pressure lines and confined spaces, increasing safety risks. In addition, ground crews can only survey limited areas each day, delaying leak detection and repair. As a result, fugitive emissions may linger undetected, undermining both safety and compliance. Thus, companies need rapid, remote solutions that deliver comprehensive coverage without risking personnel.
What Are the Limitations of Traditional Methane Leak Detection Methods in the Oil & Gas Industry?
1. Fixed CEMS vs. Mobile Surveys
Oil and gas sites often rely on Continuous Emission Monitoring Systems (CEMS) that provide 24/7 data from stationary sources, ensuring compliance with emission standards. However, they often lack the spatial resolution needed to detect leaks in inaccessible areas, such as remote pipelines or elevated equipment. This limitation can result in undetected emissions that compromise environmental safety.
On the other hand, portable handheld analyzers require technicians to physically access various parts of a facility, often traversing hazardous terrain. Teams must walk pipelines and compressor stations, slowing down surveys and delaying critical repairs. This approach not only exposes personnel to potential dangers but also limits the area that can be surveyed in a given time frame, potentially delaying leak identification.
2.2 Cost and Logistical Constraints
Implementing fixed sensors across extensive pipeline networks is capital-intensive, requiring significant investment in equipment and infrastructure. Additionally, manual surveys conducted by ground crews are labor-intensive and time-consuming. These surveys may miss intermittent leaks that occur between inspection intervals, leading to prolonged emissions and increased risk.
Given these challenges, the oil and gas industry is exploring innovative solutions to enhance methane leak detection. Integrating drone technology equipped with advanced sensors offers a promising alternative, combining comprehensive coverage with improved safety and efficiency.
