Simplification, standardization and reuse are well probably not the concepts that get technologists’ hearts beating fastest. But it is this which is the core of the group’s cost reductions on the Johan Sverdrup field.
During the ONS could oil company announce that it has reduced the cost of developing the first phase of the giant found by 20 percent.
Now there is thus likely that the development gets a price tag of 99 billion, 24 billion less than in the development plan.
Margaret Øvrum, executive vice president for technology, projects and drilling, will not be part of the Johan Sverdrup is a boring fight.
Other forms of innovation
– Johan Sverdrup is not a very nyteknisk project. It is absolutely right. But that does not mean it’s boring, you know. Very often we think technologists, for I am technologist yourself, that only technology that is fun, and that only new technology innovation. But there are many other things which are innovation, she says to TU.
She points out that doing things differently, standardize, assembling equipment and concepts from different areas – there is also innovation.
– We work with many exciting field development solutions ahead now. It includes articles about putting together things from subsea, from unmanned platforms and unmanned process platforms, which are usually not used in this way, explains Statoil director.
– So we have so clearly some areas where we require technology development and qualification. On IOR for example, there is much technical again we are considering adopting. But overall it is probably not as much as we have tended to have the field developments, stressing Øvrum.
– One of our best drilling campaigns
Among the simplifications made in Johan Sverdrup project draws Øvrum especially forward drilling and well.
– We’ve had one of our best drilling campaigns ever. Most wells in Sverdrup being standardized wells. We drill them in exactly the same way and using the same equipment. And when you do one thing 50 times and you’ll get better results than if you do it completely different from time to time, she points out.
In addition, also the wells simplified.
– As a result of that we have had a towering increase in the efficiency of drilling wells. I can not say exactly how much, but it’s very much. I said earlier that we generally have increased the number of meters per day by 70 percent since 2013. And this project is not worse than that.
In addition, she mentions subsea, documentation and technical requirements as examples of areas where they have been simplified.
Still room for improvement
In addition to cost reductions, they also eliminated bottlenecks in production so that they can now have a higher daily production.
Since the development plan was submitted There is also tension in the resource estimate for the entire field improved from 1.7 to 3.0 to 1.9 to 3.0 billion barrels of oil and gas.
Along with cost reductions, this has contributed to the first phase of the Johan Sverdrup development now has a balance price of under $ 25 a barrel.
When also future phases are built out the field will have a balance price below 30 dollars a barrel.
– And we still see room for improvement in the project, says Øvrum.
