HENNIE COLYN | Digitisation allows for oil and gas industry advancement

The oil and gas industry plays a major role in the global economy and has in recent years come under increasing pressure to meet sustainability targets while still maintaining high levels of operations and lowering the end-to-end life cycle costs of its assets.                                                          

It is a tall order which has seen owners, operators and engineers looking at strategies that will realise the above. Fortunately, thanks to advances in connectivity and digital analytics, companies can move towards a posture that allows them to enter the next phase of advanced organisational and process management in tandem with sustainability goals.

Traditionally, oil and gas processes were designed and operated independently across a plant’s life cycle. However, it had in recent years become apparent that managing processes holistically can offer dramatic resiliency and efficiency that operations and decision making needs.

Generally, processes have, for example, been operating in silos due to technical hurdles that separate various engineering domains. Digitisation can remove these barriers, ensuring that processes work in an integrated and optimised manner.

To realise the above advantages, it is important that we take one step back. The oil and gas industry generally features old infrastructure, managing large data sets of data (both structured and unstructured) which is generated from well production, refining, commodity transport, scheduling, logistics and so forth.

Technology allows organisations to collect, process and distribute this data. It can then be used for the simulation of reservoir models and visualisation of results, input on drilling locations well operations to optimise refinery settings.

But to reap the above benefits, oil and gas companies must link OT (operational technology) to IT control centres and to other facilities, which may be located across the globe. In these environments the connected systems and IT control centres must be available and resilient to ensure the consistent and continuous flow of data.

And this brings us to the next challenge. Oil and gas facilities are often located in inhospitable and remote settings with limited connectivity such as deserts or offshore platforms.

Moreover, these offshore operations produce huge amount of data – an offshore platform, for instance, can produce more than a terabyte of data a day, and may not be linked by cabling to IT facilities on land. This means a terabyte of information would have to be relayed via a remote processing centre or satellite; this is a costly exercise and can result in delays that directly impact vital decision making.

The solution is to place data centres and infrastructure (as a whole) as close as possible to the edge of the network which will yield predictable, future-proofed performance. Edge computing needs be always-on and available which then requires backup plans such as power backup (like UPS and generator equipment), especially in situations where power is generated on-site, as is the case with offshore platforms.

As mentioned, IT systems also need to be harmonised. An integrated IT architecture can enable information and control loops between system edge applications and centralised analytics and services.

Also, field devices such as circuit breakers, meters, variable speed drives (VSD) and process instrumentation embedded with sensors are able to gather data and link to central repositories of data where analytics engines can enable higher-level control and more accurate and timely decision-making.

Technology support for critical applications begins by ensuring that the required IT capability is available and resilient. Edge computing and reliable power can be critical to accomplishing these goals.

Improved IT performance enables the optimisation of the data generated by oil and gas facility infrastructure which can then be leveraged to improve production and asset performance.

Lastly, there is no doubt that streamlining oil and gas’ processes to allow for visible, reliable and accessible operations does have a number of obstacles to overcome. However, by using vendor-neutral solutions to consolidate the data that comes from equipment, manufacturing by various vendors, half the battle might already be won. 

Schneider Electric’s EcoStruxure Advanced Automation is a cloud-based IIoT environment that supports organisations’ digitisation transformation. It provides access to data across complex, multi-vendor systems in one environment while enabling oil and gas organisations to extract value, build advanced analytics and speed up IIoT deployment across multiple sites.
