The Gullfaks companions have determined to drill seven new wells and thereby enhance oil restoration by 17 MMbbl with good profitability. On behalf of the license companions, Equinor’s government vp for Development and Production Norway, Arne Sigve Nylund, offered an amended plan for improvement and operation (PDO) to the minister of petroleum and power, Kjell-Børge Freiberg, on the Sandefjord Conference.
“Our ambition is to keep up worthwhile manufacturing from the Norwegian continental shelf (NCS) for a number of many years. Wells that may be drilled quick and at a low price, close to current infrastructure, will likely be a serious contributor,” says Nylund.
The wells will likely be drilled within the Shetland Group, a carbonate reservoir that lies above the principle reservoir on the North Sea Gullfaks discipline.
Drilling on Gullfaks is difficult because of the carbonate reservoir. A effectively check in 2012 proved nonetheless that additionally this reservoir had an oil manufacturing potential. The Gullfaks companions have due to this fact invested greater than NOK one billion in manufacturing wells on this formation since 2013, which have to date produced greater than six million barrels of oil from Shetland/Lista part 1.
As this reservoir might probably produce extra oil by use of water injection, the authorities requested the Gullfaks companions to submit an amended PDO in 2019.
The Gullfaks companions (Equinor, Petoro and OMV) at the moment are able to get well much more sources by use of water injection and new manufacturing wells within the Shetland/Lista part 2 improvement. A complete of seven horizontal wells is deliberate to be drilled by use of current drilling services on Gullfaks.
“These formations that used to pose a problem at the moment are resulting from producing at a break-even under $30/bbl – I discover that to be a pleasant bonus from Gullfaks,” says Nylund.
The oil from Shetland/Lista is a small contribution to the full Gullfaks reserves, however a serious contributor to the remaining discipline potential.

Furthermore, the challenge deepens our information of carbonate reservoir manufacturing, which can be utilized in different components of the world.
