The Norwegian Petroleum Safety Authority (PSA) has given its consent to Statoil to drill four survey wells at the Johan Sverdrup field offshore Norway.
To this effect, the Norwegian oil major will use the Deepsea Atlantic semi-submersible oil drilling rig.
“Consent has been given in the form of two decisions: one for one of the wells and one for the other three,” the PSA explained in a statement.
Statoil Drills Four Wells at Johan Sverdrup
According to the PSA, the consent was given in order to obtain information about the reservoir conditions in the field.
So far, the field has been developed using four fixed facilities connected by bridges.
Drilling is scheduled to begin on 1 November and last approximately four months, while production from the field is only expect to start in late 2019.

The operation will be done at a depth of 110 metres (360.9 feet) to 120 metres (393.7 feet).
Statoil is the operator of the North Sea field, with partners Lundin Norway, Petoro, Aker BP and Maersk Oil.
Deepsea Atlantic to Drill Johan Sverdrup
The Deepsea Atlantic is a semi-submersible drilling facility of the MODU GVA 7500 type built by South Korea’s DSME shipyard in 2009.
The rig operated by Odfjell Drilling is a sixth generation deepwater and harsh environment semi-sub designed for operations at water depths of up to 3,000 metres (9,842 feet).
The Johan Sverdrup field is located on the Utsira Height in the North Sea.
Oil from the field will be piped from the Mongstad terminal and transported via Statpipe to the Kårstø processing plant in North Rogaland.
Overall, the first phase of the project involves an investment of NOK 117 billion (£11.6 billion) and daily production during the first phase is estimated to be in the range of 315,000 to 380,000 barrels per day (bpd).
