Fishbones has accomplished two reservoir stimulation jobs for Aker BP within the North Sea, rising accessible reserves on Ivar Aasen, whereas matching the productiveness of proppant fractured wells on Valhall.

In May, a Fishbones Drilling completion was put in in a brand new horizontal properly within the Ivar Aasen subject within the North Sea. The subject is operated by Aker BP, with Equinor the biggest asset proprietor. Originally, it had 180 MMboe in reserves. The properly focused the ‘alluvial fan’ formation beneath the principle producing formation on Ivar Aasen, which is a 25-meter-thick shaly, layered sandstone formation. A liner with 20 Fishbones Drilling subs, together with sand screens, was deployed with the target of connecting the layered formation whereas sustaining sand management.


The set up is taken into account successful with no operational challenges. The properly conduct up to now appears to be like promising. The profitable set up of Fishbones’s Drilling expertise signifies improved productiveness and has contributed to the success of the properly. Further wells with Fishbones Drilling in Ivar Aasen are being thought-about, in addition to in different Aker BP- operated fields.

The world's first simultaneous jetting of 72 Laterals with solids management came about on Aker BP’s Valhall subject in 2018. The set up of the slotted needles jetting system in a pilot properly on Valhall was the primary of its sort globally. Analysis of the manufacturing outcomes reveals that productiveness of the pilot properly seems to fall inside the development of proppant fractured producers in the identical subject.

After the preliminary manufacturing interval in Q1 2019, the properly stopped flowing to chalk inflow, which is widespread in Valhall wells because of the tender nature of the chalk. The chalk was lately cleaned out by coil tubing intervention and the properly is again on manufacturing. Aker BP plans to proceed producing the properly at low drawdown. The properly is presently flowing at 800 bopd.

Ole-Johan Molvig, SVP Reservoir Development, Aker BP stated “The Fishbones expertise can allow Aker BP to additional enhance restoration within the Valhall subject by lowering stimulation time and price, in addition to enabling multi-lateral design.”

Fishbones’ CEO, Eirik Renli stated “We are very pleased with our profitable contributions to worth creation for all license holders on each Ivar Aasen and Valhall. These initiatives reconfirmed the aptitude of each our Fishbones Drilling and Fishbones Jetting programs. We look ahead to proceed working with our two shareholders Equinor and AkerBP.”

“Offering an alternate method to reservoir stimulation, we’re happy to be bringing to market a greener answer, which is confirmed to additionally enhance efficiencies. We proceed to increase and strengthen our geographic footprint in an effort to meet rising demand and to carry a personalised expertise to our prospects.”
