Fishbones and Lundin Energy Norway have announced the completion of a new production well on the Edvard Grieg field. 

Parts of the reservoir on Edvard Grieg consist of conglomerates, which is a hard and tight reservoir type. The Fishbones technology, which was used on the well, increases the effective drainage radius around the production wells by drilling several small holes out from the main well. This enables the production of increased oil in what is relatively tight reservoir rocks.

The A-17 well was completed with Fishbones stimulation technology, with work now started on a second well, where this technology will also be used. 

The ‘pinholes’ drilled out from the A-17 well on Edvard Grieg are around 9 metres long and were drilled out in groups of three from Fishbones Drilling subs. A total of 53 Fishbones Drilling subs were installed, the most ever used in a single well.
