On Tuesday, March 1st, the Deepsea Atlantic drilling rig commenced on the first of a total of 35 wells to be drilled in the first phase of the Johan Sverdrup field development.
“The Deepsea Atlantic drilling rig is currently predrilling the first production well for the first phase of the Johan Sverdrup development. This is a central operation in a complex Johan Sverdrup puzzle. Predrilling allows the production capacity on the field to be utilized as efficiently as possible when Johan Sverdrup has come on stream late in 2019. This way, we maximize value from the field from day one,” says Kjetel Digre, senior vice president for the Johan Sverdrup project.

The rig is drilling the first production well through a predrilling template that was installed on the field in the summer of 2015. A total of eight wells will be drilled through the predrilling template, before the rig is relocating to drill injection wells on three locations on the field.
In 2018 the permanent Johan Sverdrup drilling platform will be installed as the second of four platforms. The drilling platform is currently being constructed at Aibel’s yard in Haugesund, north of Stavanger, and in Thailand. When the drilling platform is installed and operational, the eight predrilled wells will be hooked up from the predrilling template. At this point Deepsea Atlantic will be drilling the injection wells providing reservoir pressure support to maintain high field production.
The operator Statoil, the rig owner Odfjell Drilling and the drilling service provider Baker Hughes have cooperated closely to ensure safe and cost-effective deliveries. The Johan Sverdrup project introduces integrated drilling services as a new concept, which means that Baker Hughes will provide the main deliveries together with Odfjell Drilling.
“Statoil and the drilling service providers have worked as an integrated team in planning the drilling operation. Deepsea Atlantic is a good rig and everything is set for a safe and cost-effective drilling operation on Johan Sverdrup. This is vital to ensure production start from the field at the end of 2019,” says Digre.
The contract for integrated drilling services worth NOK 1.5 billion was awarded to Baker Hughes on 6 July 2015.
The contract for rig and drilling services on Johan Sverdrup, totalling more than NOK 4.35 billion, was awarded to Odfjell Drilling on 15 June 2015.
Contracts worth more than NOK 50 billion have been awarded by the Johan Sverdrup project. More than 70% of them have been awarded to suppliers with a Norwegian billing address.
Facts about Johan Sverdrup
Johan Sverdrup is one of the five biggest oil fields on the Norwegian continental shelf.
With expected resources of between 1.7 – 3.0 billion barrels of oil equivalent, it will also be one of the most important industrial projects in Norway over the next 50 years.
Peak production on Johan Sverdrup will be equivalent to 25% of all Norwegian petroleum production.
First-phase investments estimated int the plan of development and production (PDO) at NOK 117 billion (2015 value)
Daily production during first phase estimated at 315,000 – 380,000 barrels per day
Peak production estimated to reach 550,000 – 650,000 barrels daily
