Data to the people
Data is the new oil and we’re sharing a lot of it. Here’s how we’re doing it - and why.
In 2018 and 2019, we released two datasets to the public; the first one a complete set of subsurface data from the Volve field, and the latter data from one of our Hywind Scotland wind turbines. But if data is the new oil, why are we giving it away for free?
We made the Hywind data available in November of 2019 and the set also contains a short memo that describes the main characteristics of the assets and floating turbines, Giovanni Battista Picotti tells us.
“Our objective is to lift the floating wind industry, increase its competitiveness, support suppliers in developing solutions and establish a platform for collaboration."

For years, academia had requested access to the data to use in research and the Hywind team had long thought it would be useful to create an open data set.
“To make it relevant for analysis purposes, we wanted environmental conditions to be constant throughout the interval. So we looked for representative intervals where parameters such as wind speed and wave loading on the structure were constant,” Giovanni tells us.
“As a lecturer I’m always looking for data to provide to my students and a data set like Volve is incredibly valuable. It’s a little like winning the lottery.”

A win-win with wind
While Hywind Scotland was the world’s first floating wind farm when it opened in 2017, there are still challenges facing developing floating wind further. Which is reflected in the ways the data has been used.
“There are quite a few examples of the data being used in mooring studies. It’s one of the greatest challenges facing floating wind, both in shallow and deep waters,” Giovanni says.
Moorings keep the turbines anchored to the sea bed and are designed to cope with extreme fatigue loading, which is evident in their significant cost.
“If students, researchers, engineers and designers can get access to real-world data, they can enhance their knowledge, and use it to improve their solutions. This will benefit us in the future: a win-win situation.”

Since the dataset was made available in 2019, they’ve had about 100 requests for access. Scotland-based ORE Catapult handles the distribution of the data sets.
Hywind Scotland dataset
Consists of 11 interval measurements from one wind turbine. Each interval has a duration of 30 minutes. Accessible through the Equinor Data Portal.
- Nacelle roll/pitch motions
- Floater roll/pitch/yaw motions
- GPS measurements of surge/sway motion
- Environmental data: Wind speed, Hs, Tp, wave direction for wind sea and corresponding for swell
- Tension in mooring system: All 6 bridles in the mooring system
New life after closing
But our data sharing ventures aren’t just about floating wind. As one of the few companies in the world, Equinor released a set from the now abandoned Volve field in 2017. This set contains everything that happens from the reservoir and up to the ocean surface.
“But the data can be given new value if others, in particular research institutes and vendors, can use them to test, validate, and benchmark new technology, for example related to machine learning.”
The most comprehensive and complete open shared dataset ever gathered on the Norwegian continental shelf. Accessible through the Equinor Data Portal.
Covers a total of around 40,000 files:
- Static models
- Dynamic simulations
- Well data
- Real-time drilling data
- Production data
- Geophysical data (including interpretations)
- Various reports and more
Open to all
But the data hasn’t just helped students and researchers – it’s also helped our own software development teams. One of them is the seismic-zfp team, who are building an open source library to compress seismic data files.
These datasets are, in the truest sense of the word, simply massive and need to be compressed before they can be uploaded and used in the cloud.
“After we built the open source library, we had to test it on actual data, and the Volve data set was just perfect. It’s a manageable size, but the biggest advantage is that as a public dataset we can test it anywhere we like without a bunch of paperwork.”
“I used the Volve production data, well report and reservoir data for my final thesis in college. The data was very helpful in my work.”

“I used the Volve data for scientific research that resulted in a peer reviewed article. Data sharing is very important and can help us as researchers show what benefits the industry can achieve with appropriate use of data.”

Making development easier
The Volve data set gets around and has also been used by the Heap Purple team working on WellX. They’re building an internal library of reusable components to help visualize wellbores and associates subsurface data.
“During development we need data to experiment with, but at the time the only data we had was classified. That’s always a challenge to work with,” Øystein Lygre tells us.
Øystein has been working on the project since 2019. The data in itself is central, even though they’re working on visualizations of it and not calculations, since visualizations help users gather insight about the data.
“The data set makes development a lot easier for us and it opens new possibilities with open source. We can run demos with real data and share the code with others,” Øystein explains.
“Having the possibility of using real/realistic data while building a visualization tool allowed us to design and implement a tool that’s more effective and performant.”
