Snorre Oil Field
Summary Information
Operator: Statoil Country: Norway Location: Tampen area in the northern part of the North Sea Production start: 1992 Partners: Statoil - 33.28%, Petoro - 30.0%, ExxonMobil - 17.45%, Idemitsu - 9.6%, RWE Dea - 8.57% and Core Energy 1.11% Type: Oil Estimated Reserves: Original 249.9 million Sm³ oil 6.6 billion Sm³ gas 4.7 million tonnes NGL Production Volume: 85 000 barrels/day (2013)
Description
- The water depth in the area is 300 - 350 metres.
- Snorre A in the south is a floating steel facility (TLP) for accommodation, drilling and processing. Snorre A also has a separate process module for production from the Vigdis field. A subsea template with ten well slots, Snorre UPA, is located centrally on the field and connected to Snorre A.
- Snorre B is located in the northern part of the field, and is a semi-submersible integrated drilling, processing and accommodation facility. An amended PDO for Snorre, including a new processing module on Snorre A for processing oil from Vigdis, was approved in December 1994. The PDO for Snorre B was approved in June 1998. Snorre B came on stream in June 2001.
- Snorre C is a TLP which will be added to the field
- Oil and gas are separated in two stages at Snorre A before transport in separate pipelines to Statfjord A for final processing and export. The oil is loaded onto shuttle tankers at Statfjord and excess gas is sent through the Statpipe Gas Pipeline to Kårstø, or through Tampen Link to St Fergus. Processed oil from Snorre B is routed by pipeline to Statfjord B for storage and loading to shuttle tankers.
- All gas from Snorre B is normally re-injected, but may also be sent to Snorre A for injection or export.

History
- 1979 - Snorre Oil Field discovered
- 1992 - First oil produced
- 1998 - The PDO for Snorre B was approved
- 2001 - Snorre B came on stream
- 2010 - Aibel awarded contract for platform modifications
- 2012 - Aker Solutions awarded contract for replacement and upgrading of the drilling equipment and systems on the Snorre A platform
- 2012 - Statoil announced it was to install seismic cables on the seabed to increase oil recovery
- 2013 - Statoil recommends a third platform to increase recovery
- 2014 - Temporary shut down on Snorre B due to erosion beneath the template
Geology
- The Snorre field consists of several large fault blocks. The reservoir contains Lower Jurassic and Triassic sandstones in the Statfjord and Lunde Formations.
- The reservoir depth is 2 000 - 2 700 metres. The reservoir has a complex structure with many alluvial channels and internal flow barriers.
