Rowan drilling to stat work on ConocoPhillips Ekofisk field as the oil and gas supermajor looks to start abandonment of the field’s oil wells.
The Norwegian Petroleum Safety Authority (PSA) gave ConocoPhillips consent to use the Rowan Norway jackup drilling rig to complete ‘plug and abandonment’ work on oil wells at the Ekofisk 2/4 B platform.
No time frame has been given to the length of the work, however the PSA added that it will start during February 2016.
The giant ConocoPhillips operated Ekofisk field, located approximately 186 miles (300km) southwest of Stavanger, was discovered back in 1969 with production starting in 1971.
Ekofisk, originally bunkered its oil produce directly to tankers until a concrete storage tank was installed in field during 1973.
Over the past 40 years, the field has grown to its current 29 platforms, with oil produce being directly pumped via subsea pipeline back to the German mainland.
With much of the field being redeveloped, ConocoPhillips plans to run the field till at least 2040; however a large amount of plug and abandonment of unproductive oil wells is required.
