- Leak Detection and Repair (LDAR): This involves regularly inspecting oil and gas infrastructure, identifying methane leaks, and promptly repairing them. LDAR programs often utilize advanced technologies like:
- Optical Gas Imaging (OGI) cameras: These cameras can visualize methane leaks that are invisible to the naked eye, enabling more efficient leak detection.
- Laser-based sensors: These sensors can detect methane leaks from a distance, allowing for rapid screening of large areas.
- Drones and aerial surveys: Drones equipped with methane sensors can be used to survey pipelines and facilities from the air, providing a more comprehensive and efficient approach to leak detection.
- Venting Reduction: Minimizing the intentional release of methane during routine operations is a crucial aspect of emission reduction. Technologies and practices that contribute to this include:
- Vapor Recovery Units (VRUs): These units capture methane vapors that would otherwise be vented to the atmosphere, allowing them to be processed and used as fuel or sold.
- Green Completions: This practice involves capturing methane released during well completion operations, rather than venting it.
- Flaring Reduction: Flaring, the burning of excess natural gas, is a major source of methane emissions. Reducing flaring can be achieved through:
- Gas Utilization Technologies: These technologies enable the capture and utilization of natural gas that would otherwise be flared, such as using it for power generation or converting it to liquid fuels.
- Operational Improvements: Optimizing production processes and improving infrastructure can minimize the need for flaring.
- Pneumatic Device Replacement: Pneumatic devices, often powered by compressed air, can be a significant source of methane leaks. Replacing these devices with low-emission alternatives, such as electric or hydraulic actuators, can significantly reduce emissions.
