Use of Drones for Methane Detection
Pipelines, compressors and pumps, are often located in areas that are difficult to monitor. Any equipment failures cause irreparable damage to the environment and, as a consequence, to economic costs. This explains the importance and relevance of developing modern and technological methods of oil and gas pipelines condition monitoring.
In general, inspection methods are mainly divided into ground and aerial, and the choice between them is conditioned by the specifics of the object to be inspected. Most inspections are carried out using ground teams of specialists and special equipment: gas analyzers, thermal radiometers, laser and lidar sensors. This applies to small industrial sites where there are not extensive networks of pipelines and other utilities. Such facilities can get by with fixed instruments to provide the necessary level of safety.
In other cases, aerial methods of inspection are used, and it is especially relevant for enterprises with transportation gas and oil pipelines, facilities located in hard-to-reach places and with difficult climatic conditions. Such facilities require systematic control, as well as immediate response to prevent the potential loss of gas during production, storage and use. In such cases, rovers, helicopters and drones are used for inspections.
It is objective to believe that drones would occupy this niche and even surpass any other method due to their undeniable advantages. Drones are capable not only of visually monitoring objects, but also carrying technical aids such as multispectral visible range meters, thermal radiometers that include the near-infrared range, hyperspectrometers, lidars, radars, laser fluorescent sensors, and acoustic sensors. The cost of using a UAV with the appropriate equipment is at least 10 times cheaper than using a helicopter.
Principle of operation
The operating principle of the unmanned system is based on remote monitoring of gas pipelines routes, both horizontal and vertical with the help of special gas leakage monitoring devices. Most often gas analyzers and laser scanners are used, which determine the distance from the device to the topographic object and back.
The operation of the laser gas analyzer is based on the ability of methane to absorb infrared radiation of a certain wavelength. When the beam detects methane, the instrument analyzes the emitted power, displaying gas concentration parameters on the screen. The location coordinates, time, wind direction at the time of detection, distance to the ground, gas emission level, and other data are also automatically recorded, allowing the situation to be assessed and ground response teams to plan their actions.
UAVs reduce inspection costs
UAV Solution for Oil & Gas
DJI’s enterprise platforms are best suited for complex tasks and can be used not only to detect gas leaks, but also for visual and thermal monitoring of gas and oil facilities.
This includes pipeline integrity inspections and detection of illegal taps, assessment of the technical condition of fuel and energy facilities (corrosion, rust, defects), topographic surveys and pipeline mapping, construction work monitoring, environmental monitoring of adjacent areas, soil and relief conditions.

The most reliable solutions are the use of a payload and UAV complex: a camera and a laser gas analyzer (or laser scanner LiDAR). In this case, the company saves a lot of resources and is able to quickly solve several tasks at once, from visual imaging to identification of defects, leaks and violations in operation. This, in turn, allows ground crews to promptly respond to calls and take measures to eliminate them.
