Norway's oil and gas watchdog has approved Aker BP's plans to modify facilities at the Tambar oilfield to support North Sea oil production it said on Thursday.
The approved modification includes installation of a gas lift module to inject natural gas into
wells to help to produce oil from the reservoir.
"The gas lift is being installed because the reservoir pressure
at Tambar is no longer sufficient to ensure satisfactory production," Norway
's Petroleum safety authority said in a statement.
In March, the Tambar licence partners agreed to invest about 1.7 billion Norwegian crowns ($215 million) to extend the field's lifetime by 10 years until 2028.
Aker BP also plans to drill two new production wells in the fourth quarter of 2017, with start-up expected in the first half of 2018.
Aker BP and its partner in the licence, Faroe Petroleum , expect the modification to add 4,000-6,000 new barrels a day over several years, the company said previously.
Tambar field, which started in 2001, uses an unmanned wellhead platform remotely controlled from the nearby Ula oilfield.
