Mega, giga, tera
- 1 megabyte (MB) = 1,000 kilobytes.
- 1 gigabyte (GB) = 1,000 megabytes.
- 1 terabyte (TB) = 1,000 gigabytes or 1 million megabytes.
A 1 TB hard drive can hold 17,000 hours of music, 320,000 digital photos or 1,500 hours of video.
Maersk Oil’s senior geophysicist Line Plouman Jensen says the technology allowed for a superior image of the subsurface to be created. “The depths of the different geological formations are better understood and the data meant that we could build a convincing geological model in a complex structural setting. This information is invaluable to drillers in such a high-pressure, high-temperature environment.”
She adds: “There is still a wealth of information in the data set still to be extracted, analysed and understood.”
Another area offering huge potential to shave down costs using data is maintenance. “When you design a ship, an engine or a drilling rig, you usually make an assessment in terms of when to maintain or upgrade on a fairly fixed time schedule,” explains Boessenkool. “But our ability to gather and monitor data today could pave the way for a completely new kind of maintenance management system.”
This could have major implications in the oil industry where wells must be periodically shut down for maintenance, at a huge cost.
“Having a ‘real-time’ information flow could make us better placed to make decisions on when to upgrade equipment and potentially save a lot of money,” agrees Henrik Tirsgaard, Head of Corporate Technology & Innovation at Maersk Oil.
“One idea is to measure corrosion using acoustic signals. Combined with other parameters such as the salinity of the water produced, we could create a more accurate picture of when equipment needs changing.”
Ideas such as this one are just the beginning in terms of how data use will transform the way the Maersk Group does business in the future.
In fact, Boessenkool believes the data generated across the Group is so valuable that it should be treated as an asset in itself. “We need to look at data in the same way as we view an asset such as a ship or a drilling rig,” he says.
“I think we are just beginning to discover what data can do for us. The question in the coming years is how we experiment with it, find the potential, prove the value and use our knowledge across the Group to share that journey.”
