The oil industry has been slow to wake up to the opportunities of digital technology but this is changing. Major energy companies including BP, Shell, Eni and Statoil amongst others, are employing Digital Oilfield (DOF) technologies in their offshore drilling and production operations, for many years. As a result, DOF spending is expected to reach $17.8 billion by 2022. [i]

What are Digital Oil Fields?

Essentially  DOF technology  enables the  processing, integration and analysis  of data  transmitted  from  sensors  in offshore wells to the wellsite and control centres including purpose- built data rooms,  the  company’s  HQ or even  a consultant’s office, which are  connected by digital communications such as video conferencing.  This technology is set to drive new levels of performance in operational processes and decision making, since data transmitted from the intelligent oil field, guides well drilling and post-drill analysis.[ii] Therefore, the purpose of the digital oilfield is to maximise oil recovery and increase profitability through the use of modern sensing technology, advanced software and data analysis, reservoir visualisation and well performance evaluation.

How DOF is used?

DOF technology has demonstrated its value in exploration. Eni used big data to find the super- giant Zohr gas field in the waters off Egypt  [iii] and Anadarko discovered the Rovuma Basin off Mozambique.[iv] DOF tools  such as down-hole multiphase sensors are used by  geoscientists to analyse dig-data generated by oilfield equipment monitors.[v]  DOF technologies come into their own in complex geology such as in the deep waters of the North Sea or Gulf of Mexico. Here, DOF technology is used in the early stages of drilling to optimise the identification of the most productive and economically viable reservoirs in complex subsurface geological strata.

Benefits

There are many benefits in using DOF including, improvements in operational efficiency, productivity, greater multi-disciplinary  collaboration and better  quality decisions  derived from real-time, integrated, analysed and  interpreted  information.  For instance, GE Oil & Gas sensors placed along the length of marine drilling risers, equips the driller with databased diagnostics and insights in real- time, thereby optimising drilling.[vi] DOF tools facilitate performance measurement of drilling rigs operating in similar conditions thereby, identifying the team that reaches the target depth most efficiently and at minimum cost.

Challenges

“Big data is revolutionising big oil” said Bernard Looney, director of BP’s exploration and production business in a recent speech.[vii]  The digital oil field represents a major step forward in drilling and the production of oil, soon to be joined by the uptake of artificial intelligence (A1) to reach even higher levels of performance. However, widespread adoption of these technologies requires companies to take parallel measures in boosting their cyber security in order to protect their critical infrastructure from hacking or industrial espionage.

Prospects

In an era of low oil prices, the pressure is on big oil to reduce costs and increase efficiency whilst maintaining dividends. The oil industry may have been slow to wake up to the opportunities of digital technology but is now making up for lost time.
