Canadian Natural Resources (CNR) said today that it plans to start decommissioning the Ninian North platform next month.
Calgary-based CNR submitted its draft decommissioning programme for the rig to the UK Government earlier this year.
Ninian North is one of three platforms on the field, which lies about 240 miles north-east of Aberdeen.
Ninian North is connected to the Ninian Central platform, which exports oil and gas to Sullom Voe.
CNR bought the Ninian field from Kerr-McGee in 2002 in what was its debut North Sea deal.
It is one of the North Sea’s oldest producing fields.
Toronto-listed CNR also said has drilled one gross injector well and one gross production well so far this year.
North Sea production at CNR totalled 23,042 barrels per day during the first quarter of 2017, down 1% year-on-year.
The company’s North Sea operating costs were slashed by 23% to $36.86 per barrel.
CRNI returned to black in the first three months of this year, notching up pre-tax profits of CAN $334million.
It recorded a deficit of CAN $468million in the same period a year ago.
Revenues rose by 67% to CAN $3.6billion.
