Shell intended to apply to the Petroleum Safety Authority Norway (PSA) and the Norwegian Petroleum Directorate (NPD) to use Draugen beyond its initial cessation date. ![]() Its official producing life accordingly expired in 2013. The original PDO had assumed that the field would stay on stream for 20 years. Fotnote: Midt-Norsk Olje & Gass, no 2, 2012, ”Draugen til 2036”. Shell therefore planned to extend Draugen’s producing life until 2036. Fotnote: Sysla Offshore, 13 January 2012, ”Shell går videre med Linnorm”.Īt that time, the Linnorm and Aasta Hansteen discoveries were regarded as the cornerstones for achieving commercial development of all the gas fields in this part of the Norwegian Sea. This involved connecting all of them to a new transport system initially called the Norwegian Sea gas infrastructure, and later renamed Polarled. In the early autumn of 2012, Shell – with a number of other oil companies, and Statoil in particular – appeared to have found a way to develop several gas discoveries in the Draugen area. 2012: Big hopes for a longer producing life Read more in the separate article on the Draugen loading systems. The replacement project was initiated, but took four years to complete. Norway’s Framo Engineering developed a suitable concept in 2008. Technology for this had not been available in 1998. Weather conditions in the Norwegian Sea restricted loading, and Shell wanted to extend the operational window. That was necessary because it had been established that Draugen would continue to produce beyond the 20 years specified in the original plan for development and operation (PDO). This buoy installation stood about three kilometres from the actual platform, and was tied back to it with two 16-inch flowlines.Ī mere six years after the field came on stream, Shell wanted to replace the buoy with a loading system which could guarantee a longer operating life. Photo: A/S Norske Shell/Norwegian Petroleum MuseumĪ dedicated floating loading platform (FLP) was installed on Draugen so that its oil could be transferred to shuttle tankers for transport to land. 2009-12: loading buoy Lastesystemene ikke helt problemfrie, slep, engelsk, ombygginger på draugen Tugs pulling the loading buoy from the Draugen field. With an internal diameter of 16 inches, the pipeline from the Draugen platform to the tie-in point is about 75 kilometres long. The platform would also be able to receive gas and oil from the small Garn West satellite.Īssociated gas was to be transported to Kårstø north of Stavanger through a dedicated pipeline tied into the Åsgard Transport system through a Y connection. Intended to exploit gas from the reservoir, this development had been under way since the year before. The Draugen gas transport project, which included the installation of new equipment and a pipeline, became operational on 10 November 2002. ![]() See the separate article on the fate of the rig. Fotnote: Shell UP no 5, June 1997, ”Fjerning av boremodulen på Draugen”. Work began as early as 10 April, and was completed in exactly a month thanks to the deployment of efficient access techniques. Although only five wells had been drilled since production started, the facility was not required. The decision to remove the drilling rig on the Draugen platform was taken in January 1997. Fotnote: EPO info, no 4 1995, “Oppgraderingen på Draugen: Suksess i første fase”. Phase two of the project was carried out the following year to secure a 10 per cent rise in maximum production without affecting operating stability. Work included correcting inefficient design solutions, replacing control valves, installing larger piping and upgrading the emergency blowdown system on the second-stage separator. Maximum oil output was thereby increased to 155 000 barrels per day (b/d), which corresponded to an annual average of 140 000 b/d. This work was carried out with the platform shut down, and no problems were encountered during the subsequent restart. The first phase of upgrading the Draugen production facilities was completed over a 10-day period in late June 1995. 1995-2000 June 1995: Draugen Upgrade – production capacity increased ![]()
