The oil extraction process is accompanied by the emission of many volatile gases (e.g. CH₄, H₂S) and environmentally sensitive gases. These gases only affect the safety of on-site operations, but also lead to an increase in greenhouse gas emissions. Laser gas sensing technology is mainly used for real-time monitoring of gas leakage and environmental pollution in oil wells and the surrounding areas, providing accurate data support, thus improving operational safety, reducing emissions and realizing green production.

1. Leakage Monitoring at the Extraction Site: Laser sensors are deployed around the oil wells to monitor the concentration of CH₄ and H₂S in real time and combined with the alarm system and automated control device, they can quickly respond to the leakage and trigger protective measures.

2. Drone Inspection: Drones equipped with laser gas sensors regularly inspect oilfields on a large scale, quickly identifying CH₄ leaks and pinpointing them through GIS system.

3. Underground Gas Diffusion Monitoring: A network of laser sensors is arranged to monitor the process of underground gas escaping to the surface, providing support for environmental risk assessment and optimization of extraction strategies.

Traditional Methods: Relying on flame ionization detector (FID) or chemical detection instruments, manual operation and low sensitivity, difficult to monitor large areas in real time

Laser Sensing Advantage:

• Real-Time Online Monitoring: 7×24 hours continuous monitoring, dynamically capturing changes in gas concentration

• High Accuracy and Fast Response: Capable of detecting CH4 leaks at ppm level with high sensitivity

• Non-Contact and Remote Detection: Suitable for hazardous areas, no need for direct operation, higher safety
