![]() The marine installation contract for Draugen D3 and E3 development, which included flexible pipe and umbilical system, was given to Acergy in March 2007. FMC designed the subsea installations for diverless installation, operation and maintenance. The EPC contract for subsea well facilities at the Draugen field was awarded to FMC Technologies in 1990. The contractual agreement has an option to renew the contract every two years after the end of the initial contract period. The production capacity of the platform is about 140,000bpd.Īker Kvaerner is maintaining the platform under a five-year contract signed with Shell in 2005. Resting on a single column, the platform consists of a concrete shaft with integrated topside decks. The Draugen platform was installed in 1993. The installation will be undertaken in mid 2011. Two flexible lines will be supplied, one for reinjection of produced water and another for that of sea water. NKT Flexibles will supply two water injection flowlines for subsea installations at the field. Acergy installed a 2.3km gas lift and 2.4km production flowlines as part of the contract. Normand Mermaid and Acergy Eagle ships were used for the marine installations. The subsea wells were tied to the common Draugen platform.Īcergy installed the flexible pipe and umbilical system at Draugen in 2008. The system required nine vertical subsea trees of 5,000psi. The subsea system at Draugen, installed by FMC Technologies, includes two water injection wells, two oil production satellite wells and a gas injection satellite well. Production from the two subsea wells commenced in 2008. The new wells at the Garn and Rogn were named D3 and E3 respectively. One further subsea well was drilled in each of these reservoirs in 2007. The Rogn reservoir was developed with two subsea wells in 2002 and production from the reservoir began in November the same year. The Garn reservoir in the west of Draugen was developed with two subsea wells. Altris supplied document viewing and management software to Shell during the field development. The last three appraisal wells were drilled in 1993, 19 respectively. It was suspended initially, but re-entered later. The sixth appraisal well was drilled in 1986. Four more appraisal wells were drilled in the following year. The first exploration well, 6407/9-1, was a wild cat well drilled in 1984. “The Draugen oil field is operated by Norske Shell, which also owns a 26.20% stake in the field.”įield development has so far included drilling of nine exploration wells and 25 development wells. The field currently has six platform wells and eight subsea wells. The Draugen field was initially developed with five subsea wells connected to a central platform. The Rogn and Garn deposits are homogeneous and both lie at a depth of 1,650m. The other deposit, located in the west, is the Garn formation of middle Jurassic age. The main reservoir contains sandstone of Rogn formation, found to be of the late Jurassic age. ![]() The Draugen field produces oil primarily from two reservoirs. The remaining reserves stood at 19.7 million cubic metres. The discovery wellbore was a wild cat well designated 6407/9-1.Īs of 31 December 2009, the recoverable oil reserves at Draugen stood at 145 million standard cubic meters. The field was discovered in 1984 by the first well drilled in the block. Shell is yet to resume operations at the facility. The field was shut down in February 2010 due to cold weather and extreme winds.
