DONG Energy holds a strong position in Denmark through production of oil from the Siri-area (including the Nini, Nini East and Cecilie fields) and the South Arne area (including the Lulita field). Nini East was put in production at the beginning of 2010 and DONG Energy estimates that there is still potential in the area around the Siri field.
Still potential in the North Sea
At the beginning of 2012, DONG Energy made the final decision concerning the development of the Hejre field, the deepest oil field in Denmark so far, in co-operation with our licence partner. DONG Energy is operator of the field. The development of the field makes a significant contribution to the development of the existing infrastructure in the Danish sector of the North Sea. We expect that the field will be put in production in 2015.
In the Solsort/Svane licence, there was focus on evaluating a recent oil discovery in the Solsort field in 2011, and continuing the preparations of evaluating the production properties of the deep-seated Svane gas discovery.
Further development of South Arne
In 2010, it was decided to further develop the northern part of the South Arne field (phase 3). The development project has been initiated and it is expected that the first new wells will start producing in 2013.
Cracks in subsea structure
At the end of 2009, a routine inspection revealed cracks in a structure mounted on the outside of the storage tank which is part of the oil storage tank structure below the Siri platform. We are in the process of installing the permanent solution which is necessary to maintain safe operation for many years to come.
DONG Energy is active in the Norwegian sector of the North Sea, in the Norwegian Sea and in the Barents Sea. Exploration & Production is operator of the Trym and Oselvar fields, and initiated development of these fields in 2009.
The Trym gas field was put in production at the beginning of 2011. The natural gas is transported from the subsea facilities to the treatment facility in Nybro, Denmark, via the Danish Harald and Tyra platforms, while the light oil condensate is transported to the terminal in Fredericia via the Oil pipe.
Production from Oselvar since 2012
The Oselvar oil and gas field field was put in production in April 2012. Most of the gas production from the field is transported to the Ula field for injection, for the purpose of enhancing oil production from Ula.
Both development projects are important elements of DONG Energy’s strategy of utilising existing platforms and transport systems in connection with development of the smaller fields in the area.
17 wells in production in the Ormen Lange field
The development of the Ormen Lange field has continued with installation of another subsea production unit, and now, there are 17 wells in production in the field. It is expected that gas can be produced in the field for many years to come, and development will continue to ensure optimum utilisation of the reserves.
Marulk put in production in 2012
In 2010, DONG Energy decided to initiate the development of the Marulk gas field in co-operation with the operator ENI. The field is located in the mid-Norwegian area, close to the Alve field that was put in production in 2009. Marulk was put in production in April 2012. The production from the subsea production units in the Alve and Marulk fileds are transported to the Norne production vessel where the gas and oil undergo treatment before further transport and unloading.
The Barents Sea – part of a long-term strategy
In 2009, DONG Energy was awarded its first licences in the Barents Sea and drilled its first exploration well in 2011 as operator in the area. The activities in the Barents Sea are an important element in finding and developing oil and gas reserves to maintain DONG Energy’s production rates in the long term.
The West of Shetland area is DONG Energy’s focus area for oil and gas activities in the United Kingdom.*
DONG Energy has been active in the area since 2000 and has been involved in all significant discoveries made in the area.
Development with important pipeline system
In 2010, DONG Energy decided to develop the Laggan-Tormore fields in co-operation with the operator Total. The development of these fields also comprises establishment of a gas transport system to Scotland via the Shetland Islands.
There is focus on establishment of the transport system because it will be the first in the area and therefore provides the opportunity for use of this transport system for other existing and future discoveries in the area.
It is expected that the Laggan-Tormore fields will be put in production in 2014.
Discovery in the Glenlivet licence
In 2009, DONG Energy made a gas discovery in the Glenlivet field through its first exploration well, as operator in the West of Shetland area.
Glenlivet is located close to the Laggan-Tormore fields and DONG Energy is now working on plans for development of the field, including the options for using the transport systems around Laggan-Tormore.
Discovery in the Edradour licence
In 2010, DONG Energy made another discovery through exploration drilling in co-operation with the operator Total - Edradour which is also located close to the Laggan-Tormore-fields. Just like with Glenlivet, work is being performed concerning plans for development of Edradour.
Maturation of Rosebank and Cambo
In the Rosebank and Cambo fields, the work on maturing the fields for development continues. In the Rosebank licence, seismic acquisition was completed with success in 2010 using new, advanced technology, where microphones capturing seismic sound waves have been mounted directly on the seabed. The results contribute to assessing the scope of the field.
On the Faroe Islands, DONG Energy participates in two licences.
In 2012, efforts were focused on appraising the exploration potential of the licences as well as regional.
In West Greenland, DONG E&P is operator in an exploration group also comprising Exxon, Chevron and Nunaoil. A thorough assessment of the prospectivity is ongoing and expected to be completed by end of the year with a recommendation on the way forward.
In the Baffin Bay, NW Greenland, DONG E&P is involved in an exploration licence together with ConocoPhillips and Nunaoil. In 2012, 3295 km of 2D seismic was acquired. In addition a number of stratigraphic cores were acquired as part of a joint industry project. The data are now being analysed and evaluated before a decision on a possible exploration well is made.
