Norway’s Statoil has reported that the Statfjord satellite fields, in the North Sea, are producing almost 50% more in 2015 than previously expected, and thus pass 10 000 barrels of oil equivalent on average per day in 2015.
The Norwegian oil and gas company Statoil is the operator of the field with 44.3% stake and its partners are ExxonMobil and Centrica.
Mette H. Ottøy, Statoil’s senior vice president for Operations South in DPN, said: “Statfjord is our oldest field, and original plans called for decommissioning many years ago. Instead the life of Statfjord has been extended several times, and we now have a horizon of another ten years of profitable production and activity.
“Thanks to good planning and a successful campaign by the Bideford Dolphin drilling rig we are producing more than expected from the Statfjord satellites. This helps sustain the life of the Statfjord field.”
New wells planned for 2016
The company stated that it was still maturing recoverable resources in the Statfjord area thanks to an active drilling program.
In 2015 we have drilled 11 wells and are planning nine in 2016, said Statoil.
Bideford Dolphin has been at the Statfjord satellites from April to September 2015. During this campaign Bideford has drilled one producer, performed workover on two injectors and permanently plugged five wells, the company reported.
Third consecutive increase
Statoil also stated that Statfjord has increased its annual production for three consecutive years from 2012 to 2015. The company explained that, initially an oil field, Statfjord has been transformed into a producer mainly of gas for customers on the Continent, and in the UK.
“Twelve years ago the partnership made the bold decision to reconstruct the entire field for gas production. Good work in our own organisation, among the partners and suppliers, in addition to NOK 23 million in capital expenditures have enabled us to maintain this high production level from Statfjord,” says Mette H. Ottøy.
Originally the partnership hoped to recover 40 percent of the oil in the Statfjord field. Statoil emphasized that the result so far was a record-high 66 percent, while the average recovery factor for oil fields worldwide is 35 percent.
The Statfjord satellites consist of the Statfjord East, Statfjord North and Sygna fields, with the following licensees in two or three of the fields: Statoil (operator), Centrica, DEA Norge, ExxonMobil, Idemitsu and Petoro.
Statfjord East, Statfjord North and Sygna are all tied back to the Statfjord C platform as satellites.
