Doubled Reserves – Won IOR Prize

Tuesday 28 August 2018

The licensees for the Alvheim field in the North Sea have been awarded the Norwegian Petroleum Directorate’s improved oil recovery (IOR) prize because of their willingness to accept risk.

Adopting new technology, sharing data and being able to view a wider area as a whole have helped to more than double available reserves from this area.

The award was presented for the 15th time by NPD director general Bente Nyland at an event during the ONS 2018 oil show in Stavanger on 28 August. Representatives from Aker BP (operator with a 65 per cent interest), ConocoPhillips (20 per cent) and Lundin (15 per cent) were called onto the stage to receive the prestigious prize.

Alvheim came on stream in 2008. Since then, extensive data-gathering has led to the continuous identification, maturing and drilling of new well targets. In addition, an exploration programme around the field has resulted in further discoveries and the development of a number of new finds.

Discoveries beyond Alvheim’s immediate vicinity, such as Vilje, Volund, Bøyla and Skogul, have also been tied back to the field. This has helped to more than double reserves in the Alvheim area compared with the figure given in the approved plan for development and operation in 2004.

Drilling of pilot wells and multilaterals, extensive use of oil and water tracers, four-dimensional seismic surveying, inflow control devices (ICDs) and autonomous ICDs (AICDs) are among the technologies which have made it possible to optimise Alvheim production and all the tie-backs of reservoirs which consist to a great extent of relatively thin oil columns.

Good experience with advanced completion solutions (the ICDs mentioned above) to reduce gas production and thereby increase oil output has led to a research project and plans to install AICDs as a further development to close off unwanted water or gas production.

The other finalists nominated by the jury were the Resman technology company and professor Svein Skjæveland at the University of Stavanger.

The following criteria are given emphasis when selecting winner candidates

- Implementing new technology or applying established technology in a new way

- More intelligent working methods and processes

- Maturity of the project

- Willingness to take risks, boldness and daring

- Outstanding research
