AI could make oil and gas a little less dirty

Artificial intelligence can reduce oil spills and methane gas leaks for oil and gas companies, but its use comes with its own environmental costs.

Staying green is no longer a matter of choice for companies. All business sectors face intensified scrutiny over how they protect the environment. This is especially true for the oil and gas industry. Technology such as artificial intelligence (AI) could help them deliver – at least to some extent.

While the idea of innovative technology helping big oil to protect the environment may sound like the exact PR line Silicon Valley loves to spin, automation can be beneficial.

Take oil spills. They represent the worst sort of disaster oil companies face, both in terms of bad publicity and for the horrific effect on marine life and habitats. Technology could help cushion the blow and even avoid the danger altogether.

Predictive analytics is one form of AI that can help identify oil spills soon after  –  and sometimes even before – they occur, giving companies vital extra time to minimise the damage. The US Department of Energy’s National Energy Technology Laboratory (NETL) provides an example of how it can work.

NETL has developed an Offshore Risk Modelling (ORM) suite that evaluates and reduces the risk of oil spills. The suite offers digital modelling and visualisation tools that can simulate spill scenarios. It uses machine learning and AI to factor in information regarding ocean currents, emergency response availability and even the behaviour of oil particles in the water. The ORM tools can also identify pressure during drilling activities and assess the integrity of offshore infrastructure.

A load of hot air?

Luckily, oil spills remain rare events. The far bigger and more common environmental blight caused by the oil and gas brigade is that of methane emissions. Methane gas leaks from production, distribution and storage wells contribute significantly to total emissions. Oil and gas operations emitted around 70 million metric tonnes of methane into the atmosphere in 2020, according to the International Energy Agency.

BP provides an interesting case study of where AI can provide a solution to methane leaks. A few years ago, the oil and gas major partnered with US-based Kelvin, a creator of AI-powered control applications. The goal was to eliminate 3.5 million tonnes of annual greenhouse gas emissions. In 2017, the company identified the Wamsutter field in Wyoming as a target for methane leak reduction. Consequently, a number of sensors, including methane-detecting cameras, were installed at the Wamsutter gas wells. Real-time field data was relayed by the sensors to Kelvin’s AI system, which produced simulations facilitated by BP’s historical data for the site.

Six months after implementation, a 74% reduction in methane leaks from the Wamsutter wells was recorded. This was thanks to predictive maintenance pre-empting equipment failures, empowering operators at Wamsutter to mitigate them. Not only did BP reduce its greenhouse gas emissions, but production volumes at Wamsutter rose by 20%, while operating costs were slashed by 22%. Similar sensors are now planned for all BP wells.

Edge of discovery

This use of cutting-edge technology comes after a massive revenue slump for the oil and gas sector. As GlobalData analysts reported in their recent review of industry contracts, the number of global oil and gas contracts decreased by 28% between 2019 and 2020.

While Covid-19 contributed to the drop, the biggest cause was a shortage of easily available resources. Most shallow-water deposits are already under development, forcing companies to turn to remote reserves that are hard to discover, costly and dangerous for workers.

AI could improve discovery and enable companies to achieve the same output with fewer sites, reducing environmental damage in the process. One product doing that is SparkPredict. Developed by US AI vendor SparkCognition, the product analyses seismic and subsurface data to boost site discovery.

Oil and gas giants certainly recognise how important AI is to site discovery. Saudi Aramco has invested in Earth Science Analytics, whose software predicts rock and fluid properties in the subsurface. France’s Total announced plans in 2019 to open a digital factory that will use AI to accelerate field discovery (one no doubt made possible by the Google partnership it struck before the latter pledged in 2020 to no longer create custom tools for oil and gas).

No wonder GlobalData analysts not only estimated that the oil and gas AI market was worth $2.1bn in 2020, but that it will double in size by 2024. What may complicate matters are the remote settings oil and gas companies will venture to in search of reserves, how long technology can keep up and the robustness of demand – the IEA's net-zero 2050 scenario foresees no new oil and gas fields approved for development beyond projects already committed as of 2021 and “some fields may be closed prematurely”.

Where AI runs out of gas

As discussed in a Forbes report from 2019, there are several advantages of applying edge computing to oil and gas. The edge keeps computation and data storage closer to the location where it is needed – in other words the opposite of cloud computing.

The cloud offers value that edge does not, in that it facilitates remote monitoring centres that offer personnel safety and dispatch advantages. George Monaghan, GlobalData

“While technologies such as cloud computing and hybrid storage have been touted as solutions, these still rely on data being transmitted, and with many offshore facilities working on satellite communications at a speed of about 2Mbps that is still not practical,” Jane Ren, CEO and founder of smart system brand Atomiton, told Forbes.

However, not everyone is confident edge computing is more beneficial to businesses. “The cloud offers value that edge does not, in that it facilitates remote monitoring centres that offer personnel safety and dispatch advantages,” says George Monaghan, an analyst at GlobalData. Monaghan notes that Russian oil company Rosneft has installed data monitoring centres with AI capabilities at 97% of its heavy drilling rigs.

The jury is out on the environmental implications of cloud computing. Part of the reason is cloud computing requires data centres, the running of which requires a lot of energy. Given that a typical oil platform can generate up to 2TB of data every day, running their data centres could adversely affect the environment too. Big oil means big data, data that historically has remained siloed due to infrastructure and technology gaps. Freeing this data will be necessary for AI’s full capabilities to work – and will no doubt require more data centres to be built.

Summing up AI in oil and gas

No matter how technology adapts to the physical challenges posed by oil and gas ventures, AI and machine learning will change the industry and are in fact already doing so.

Net zero poses an existential challenge to fossil fuels, but the use of AI may be able to offset some of the industry’s environmental impact, especially if green solutions can be found to handle all its data.

Oil and gas leaders may find that AI’s environmental solutions help profits while changing the public image of their brands for the better. AI vendors queasy about associating with fossil fuels should tailor products more to the risk and discovery end  – it is not a silver bullet, but their wares can help make oil and gas at least a little bit less polluting en route to carbon neutrality.
