NCS: Gas at Rumpetroll

Aker BP hit hydrocarbons in the Rumpetroll injectite prospect in the North Sea. The wells overall proved a gas column of minimum 77 metres.

The purpose of wildcat 24/9-13 was to prove hydrocarbons in the Eocene sand injectites, whereas the appraisal 24/9-13A had to prove petroleum/water contacts.

Well 24/9-13 encountered a gas column of about 3 meters in the Palaeocene Hordaland Gp, whereof a total of 2 meters of sandstone with mainly good reservoir quality.

Hydrocarbon shows were also identified in the Balder Fm, in good quality sandstone layers, totalling 17 m.

According to NPD, the sandstones are interpreted as being remobilised sand from the Heimdal and Hermod Fm., and injected into overlying stratigraphy in the Rogaland and Hordaland Gp.

24/9-13 A encountered a 40  meters gas column in injectite zones, of which a total of 7 metres of sandstone with good to very good reservoir quality. The sandstones are interpreted as being injected sands in the Hordaland Gp.

Petroleum/water contacts were not encountered in any of the wells.

Rumpetroll was drilled south of Bøyla field, Frosk and Froskelår discoveries. Preliminary estimates place the size of the discovery between 3.7 and 10.7 MMboe.
