The Draugen oil field is run by Norske Covering, that also owns a 26.20% stake within the field. The rest of the stake takes place by Petoro (47.88%), BP Norge (18.36%) and Chevron (7.56%). The area is based on block 6407/9 within the Haltenbanken area that is situated about 140km from Kristiansund, Norwegian. The area is based on production licence PL093.
Inside a contract believed to become worth NKr200m ($34.16m), Aker Offshore Partner (a subsidiary of Aker Solutions) will generate a water reinjection system in the Draugen field. Anything was awarded by Covering in December 2009. The contractual scope includes engineering, procurement, construction and installing of the reinjection system. Aker expects to accomplish cellular phone by The month of january 2012.
The area was shut lower in Feb 2010 because of cold temperature and extreme winds. Covering is yet to resume operations in the facility.
Draugen field discovery and reserves
The area is discovered back in 1984 through the first well drilled within the block. The invention wellbore would be a wild cat well designated 6407/9-1.
By 31 December 2009, the recoverable oil reserves at Draugen was at 145 million standard cubic meters. The rest of the reserves was at 19.seven million cubic metres.
The Draugen field produces oil mainly from two reservoirs. The primary reservoir contains sandstone of Rogn formation, discovered to be from the late Jurassic age. Another deposit, found in the west, may be the Garn formation of middle Jurassic age. The Rogn and Garn deposits are homogeneous and both lie in a depth of just one,650m.
Draugen field development
The Draugen field was developed with five subsea wells linked to a main platform. The area presently has six platform wells and eight subsea wells. Of those, 12 are production wells.
Field development has to date incorporated drilling of nine exploration wells and 25 development wells. The very first exploration well, 6407/9-1, would be a wild cat well drilled back in 1984. Four more evaluation wells were drilled in the year after. The sixth evaluation well was drilled in 1986. It had been suspended initially, but re-joined later. The final three evaluation wells were drilled in 1993, 1999 and 2003 correspondingly. Altris provided document viewing and keeper to Covering throughout the field development.
The Garn reservoir in the western world of Draugen was created with two subsea wells. It started production at the end of 2001. The Rogn reservoir was created with two subsea wells in 2002 and production in the reservoir started in November exactly the same year. Any subsea well was drilled in all these reservoirs in 2007. The brand new wells in the Garn and Rogn were named D3 and E3 correspondingly. Production in the two subsea wells commenced in 2008.
The subsea system at Draugen, installed by FMC Technologies, includes two water injection wells, two oil production satellite wells along with a gas injection satellite well. The machine needed nine vertical subsea trees of 5,000psi. The subsea wells were associated with the most popular Draugen platform.
Acergy installed the flexible pipe and umbilical system at Draugen in 2008. Normand Mermaid and Acergy Bald eagle ships were utilised for that marine installations. Acergy installed a couple.3km gas lift and a pair of.4km production flowlines included in the contract.
NKT Flexibles will give two water injection flowlines for subsea installations in the field. Two flexible lines is going to be provided, one for reinjection of created water and the other for your of ocean water. Cellular phone is going to be carried out in mid 2011.
The Draugen platform was set up in 1993. Resting on one column, the woking platform includes a concrete shaft with integrated topside decks. The development capacity from the platform is all about 140,000bpd.
Aker Kvaerner is maintaining the woking platform within five-year contract signed with Covering in 2005. The contractual agreement comes with an choice to renew anything every 2 yrs following the finish from the initial contract period.
The EPC agreement for subsea well facilities in the Draugen field was awarded to FMC Technologies in 1990. FMC designed the subsea installations for diverless installation, operation and maintenance.
The marine installation agreement for Draugen D3 and E3 development, which incorporated flexible pipe and umbilical system, was handed to Acergy in March 2007. Acergy awarded water injection flowlines supply contract NKT Flexibles in May 2010.
Bjørge Eureka, the Norwegian subsidiary of Bjørge, was awarded an agreement in This summer 2009 to upgrade the generator system in the Draugen platform and offer centrifugal pumps towards the platforms.
Covering started producing oil in the Draugen field in October 1993. Utilization of 4D seismic technologies have helped Covering to improve the development existence from the Draugen field. The organization expects to carry on production in the field a minimum of until 2024.
The typical oil production in the field in ’09 was at 63,000bpd, a loss of 14.8% over 2008. Production continues to be falling continuously since 2004 once the average production was at 144,000bpd. Various production optimisation initiatives happen to be carried out by the organization through the years. To be able to increase oil recovery and production, the organization is intending to then add more wells towards the field.
The Garn West reservoir is attached to the Draugen platform with a 3.3km-lengthy pipeline. The pipeline laid through the Garn West reservoir connects the Rogn deposit towards the project platform.
As the oil obtained from the area is used in a floating loading buoy, the connected gas is transported to processing plant at Karsto by way of the Asgard Transport pipeline.
