Drones have numerous economic and environmental benefits that enable oil and gas companies to reduce costs, improve efficiency and competitiveness. Generally, the devices are used in all phases of oil and gas activities and have the potential to support the extraction, production, and distribution.
As the drone and sensor technology continues to improve, they now have more abilities that enable them to perform a wide range of inspections and monitoring roles, and replace or supplement the traditional methods. This allows oil and gas companies to detect existing and potential faults, as well as security issues that may affect the infrastructure and the workers.
How oil and gas companies will use drone in the future
With more competition, fluctuating prices and dwindling stocks in existing wells, the oil companies are likely to employ drones and other new technologies as they move towards non-conventional sources and challenging environments. Although the unmanned vehicles will have many different uses in the future, here are the top three drone applications in oil and gas industry in 2020.
- Oil and gas exploration
- Inspecting and monitoring pipelines
- Oil and gas operations
Oil and gas exploration
The unmanned vehicles provide a cost effective and safe solution in existing and new onshore and offshore sites. In particular, the devices can help oil and gas companies to carry out aerial, underground and undersea explorations. In addition to providing visual images, they can carry out other functions such as water sampling and creating 3D maps of prospective sites and surroundings.
The data from oil rigs, offshore platforms and other areas provide valuable information that companies can use to improve operations, production and efficiency as well as ability to forecast and address breakdowns. During exploration, the appropriate sensors and software tools will provide a faster way of collecting data and calculating the geological and seismic data in onshore and offshore exploration sites.
Drone inspections enables researchers to collect vital information from prospective oil wells. Using other technologies such as laser scanning and GPS, the drones will provide topographical information about the new locations even before sending people to the ground. This will also help in determine the best location where to install the facility, access routes and other logistics. Using GPS and laser scanning technologies, the UAVs will generate 3D maps which are instrumental in determining the shape and elevation of objects and a drone’s surrounding. Such maps will include landmarks such as mountains, rivers, buildings, roads and other important features that will help the engineers to plan well.
The aerial inspection provides visual images and companies can use these to get round the clock updates of the operations such as construction work. They can also help in detecting hazards or issues that require attention
The underground exploration involves using drones inside hollow tubes inserted in the ground. These can then collect important data, including images that can help researchers determine the presence of oil products.
The same can be done for undersea facilities where the drone will also have the ability to collect sample water samples from different locations. Samples from offshore and underground facilities are then analysed by chemists to find if there is presence of oil products.
Application of drones on oil and gas pipelines
The unmanned vehicles provide a wide range of services in ensuring that pipelines are operating efficiently and safely. The drones provide a faster and cost effective means of inspecting pipelines – something which would traditionally take weeks or months, expensive equipment, resources and manpower. In addition, the drones are able to access difficult terrain, remote locations and other hard to reach areas without exposing the workers to risks.
Main applications of drones include inspection, monitoring pipeline, repairs, checking for natural conditions, etc.
Regular inspections can detect leaks, spills, and damages that may cause spillage and environmental degradation. Equipping the drones with the correct sensors enables them to provide visual inspections of both the internal and external surfaces. Identifying the direction of the spillages or gas leaks will help evacuate or keep people away from potential toxic and fire risks
Other than the physical pipeline, the drones will monitor the structure against external threats such as vegetation encroachment, theft, and sabotage, as well as natural hazards such as earthquakes. In particular, special drones will be used to detect and report any seismic activities near the pipelines.
Such information will enable companies to respond promptly and reduce the impact of natural disasters. For instance, they can temporarily close the valves and stop the flow of the products, alert people in the near vicinity, and take other precautionary measures that reduce potential risks.
As technology advances, there will be drones equipped with robots that will give them the ability to repair damages, both inside the hollow spaces as well as the exterior surfaces.
Drones in oil and gas operations
The unmanned autonomous vehicles will help to streamline and improve the purification and manufacturing processes by supporting operation functions such as analysis, product segregation and logistics. For example, they can be used to carry samples, perform inspection of the processes and products as they move through different stages within the plant.
UAVs are also useful in inspecting buildings, tanks, and other vertical infrastructure, as well as confined spaces such as inside the tanks and pipes. Advantages include improved safety and inspecting the structures while they are still operating, hence minimizing shutdowns and risks since workers do not have to climb or go to dangerous locations.
As such companies will be using more of the technologies to inspect the flare stacks, cooling structures, tanks and others. Regular inspections and monitoring of these structures enable early detection and fixing of potential faults.
Besides regular inspections to identify any issues, that drones are also great damage assessment tools. Companies will also use them to enhance the safety and health of the workers. Equipped with the appropriate sensors and instruments, the drones will help the improve operations, safety and support emergency services such as evacuations.
In particular, they will be able to highlight and warn the workers about hazardous locations and environments during the exploration and extraction activities. They are also very useful in rescue missions as they can take aerial views, and indicate the safest escape route.
Other than improving monitoring and inspection of the infrastructure which enhances operations and productivity, UAVs can be used for medical purposes. Integrating other technologies and teleconferencing will allow physicians to even diagnose and treat field workers in oil rigs and remote areas.
During operations, the UAVs provide aerial inspections both in normal and emergency situations. They can
· Perform security surveillance and send alerts in case of an emergency or intrusion. They are also useful during emergency operations and can provide live feeds of the situation, including safe escape routes, or direction of fire is spreading to or liquids are spilling towards.
· Record all the activities and status of the assets. This provides the maintenance and security teams with the evidence or the backup of the activities at the facility, something which can be useful when investigating ethical or legal issues in the future.
Benefits of using the drones in oil and gas industry
The drones are ideal for providing a continuous monitoring of pipelines and other infrastructure. Generally, most drones have flexible plug and play payload, others may combine several sensors and abilities to perform complex inspection and process the data.
Major benefits of using the UAVs include improved safety, low cost, gathering and providing detailed visual and other inspection data from critical assets.
By providing regular, inexpensive and fast inspections, the drones improve the efficiency and productivity. This is because they can identify existing and potential faults, thus enabling maintenance teams to rectify them in good time.
