sgard Subsea Gas Compression
Norwegian Petroleum Directorate The Norwegian Petroleum Directorate (Norwegian: Oljedirektoratet) or OD is a Norwegian government agency responsible for the regulation of the petroleum resources on the Norwegian continental shelf. Based in Stavanger, it is to ensure that the petroleum resources are allocated in an optimal at the same time as they incur minimal environmental impact. It is subordinate to the Norwegian Ministry of Petroleum and Energy. Remember: PDO: Plan for Development and Operation of a petroleum deposit. PIO: Plan for Installation and Operation of facilities.

Norwegian Sea, North Sea and Barents Sea
sgard Subsea Gas Compression System
Haltenbanken area The Haltenbanken area in the Norwegian Sea contains a number of challenging oil and gas fields that require advanced technology for improving the oil recovery. Haltenbanken is located at the west of Tr ndelag in the Norwegian Sea, is an interesting area for both production and exploration. First production from Haltenbanken started in 1995. The Haltenbanken operations in Stj rdal.
Haltenbanken area At Haltenbanken you find the following fields in production: Heidrun sgard including Sm rbukk, Sm rbukk S r and Midgard Kristin Tyrihans Morvin Mikkel Njord
Introduction to sgard The sgard field lies on the Halten Bank in the Norwegian Sea, about 200 kilometres off mid-Norway and 50 kilometres south of Heidrun. The sgardA operated from 1999. sgard B platform began on 1 October 2000. The sgard field comprises the Midgard, Sm rbukk and Sm rbukk South discoveries.
Introduction to sgard sgard ranks among the largest developments on the Norwegian continental shelf, embracing a total of 52 wells drilled through 16 seabed templates. The sgard field is located in the Norwegian Sea about 260 kilometers west of Br nn ysund. The field has been developed with the sgardA installation (production ship) for production of oil and condensate. The gas is produced from a floating installation ( sgard B), while the condensate is stored on the sgard C (storage ship).
Introduction to sgard Crude oil, condensate and gas are produced from sgard. Crude oil and condensate are mixed to form a light oil called sgard blend. The liquid is pumped from storage tanks into shuttle tankers which sail between the fields and the different refineries. Gas from sgard is piped through sgard Transport to the K rst processing complex, north of Stavanger. The heavier components, such as ethane, propane, butane and naphtha are separated out at K rst . The dry gas is piped to continental Europe. sgard supplies about 11 billion cubic metres of gas annually to European customers.
Introduction to sgard Transport: The sgard development links the Halten Bank area to Norway's gas transport system in the North Sea, putting long-standing plans for a pipeline connection into effect. Growing demand for Norwegian gas from continental Europe has made this possible, and sgard will help to meet the planned expansion in Norway's gas exports. Gas from the field is piped through the sgard Transport line to the treatment plant at K rst north of Stavanger and on to European customers. Oil produced via the A vessel is shipped from the field by shuttle tankers.
sgard Subsea Gas Compression The Midgard and Mikkel gas reservoirs in the sgard field have been developed as subsea field installations. The wellstream from both fields, which are located 50 and 70 kilometres away respectively, is sent in the same pipeline to the sgard B platform. Analyses show that towards the end of 2015 the pressure in the reservoirs will become too low to avoid unstable flow and maintain a high production profile to the sgard B platform. Compression is necessary to ensure a high gas flow and recovery rate. The technology will increase recovery from Mikkel and Midgard by around 282 million barrels of oil equivalent.
sgard Subsea Gas Compression The subsea gas compression technology will boost falling gas pressures from sgard s two subsea satellites, Midgard and Mikkel. The system will allow stable production to continue and enable an additional 280 million barrels of oil equivalent to be recovered. A dry gas compressor system will be used on sgard. Gas and liquids are separated before boosting. The liquid is boosted by a pump and the gas by a compressor. After boosting, gas and liquids are mixed into the same pipeline before transport to sgard B.
