In a report that looked into the adoption of robotics across the petroleum industry, Rystad found that existing solutions could replace hundreds of thousands of oil and gas jobs globally and reduce drilling labour costs by several billion dollars by 2030 if there is an industry push for such a transition.
One of the segments with much to gain from the adoption of robotics is drilling, as it is highly cost-intensive and involves carrying out dangerous tasks in challenging environments.
Robotic solutions have already been introduced successfully in drilling operations, with companies such as Nabors at the development forefront.
Applying current supplier specs, which suggest that robotic drilling systems can potentially reduce the number of roughnecks required on a drilling rig by 20 % to 30 %, Rystad estimates that such a reduction in both offshore and onshore drilling crews can bring cost savings of more than $7 billion in wages in the U.S. alone, based on present wage levels.
Inspection, maintenance, and repair (IMR) operations are also ideal for robotic operations and is the segment where adoption of robotics has gained the most traction among operators in recent years.
This has so far mainly been limited to subsea IMR activities, but we are now starting to see IMR robotics solutions also being used for topsides.
Overall, Rystad Energy believes that at least 20 % of the jobs in segments such as drilling, operational support, and maintenance could in theory get automated in the next 10 years.
Looking at the current staffing headcount of some key oil and gas producing countries, the U.S. could reduce its staffing needs by over 140 000 employees and Russia by over 200 000 personnel.
Sumit Yadav, an energy service analyst at Rystad Energy, said:
- Despite the huge potential of robotics, operators should be aware that these savings will be partially offset by the considerable investments required for the adoption of these solutions, which may vary depending on the cost structure and whether the robots are owned or leased
While the emergence of robotics in the oil and gas industry seems inevitable, Rystad believes that full-scale adoption is still a few years away as the long-term reliability of robotics in complex 3D environments such as those found on offshore platforms is yet to be tested.
Another challenge in the implementation of robotics is limited communication capabilities, especially between robotics units.
If robots are to fully replace humans, it is imperative that these systems communicate seamlessly to unlock true value.
Rystad emphasised that the implementation of such communication systems is both complex and costly.
Finally, job cuts due to robotics are likely to be met with some resistance from labour organizations, and robotized work processes may also need to pass regulatory hurdles as authorities seek to ensure that the operational changes brought on by the new technology satisfy safety and environmental standards.
