Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
The 7226/2-1 Ververis well was drilled on a dome structure on the Bjarmeland platform in the Barents Sea. The objective was to prove hydrocarbons in the Realgrunnen Group of Jurassic age, in the Snadd Formation of Carnian age and in the Kobbe Formation of Anisian age.
Operations and results
Wildcat well 7226/2-1 was spudded with the semi-submersible installation Polar Pioneer on 18 May 2008 and drilled to TD at 2992 m in the Early Triassic Havert Formation. No significant problems were encountered in the operations. No shallow gas was observed. The well was drilled with Seawater and hi-vis bentonite pills down to 544 m and with FormPro mud from 544 m to TD.
The Ververis well penetrated a short Quaternary section and then a thin section of Cretaceous before dissecting both the Jurassic and Triassic sections. The well showed gas in the Kobbe Formation. There were also indications of hydrocarbons in the Havert Formation where the sandstones showed high resistivity during drilling, but the MDT log indicated that the reservoir was tight. No hydrocarbon/water contacts were observed in the well, only lithological gas-down-to contacts. In the Kobbe Formation on Obesum and in the Havert Formation on Ververis, there are strong indications that low permeable zones were plugged because of the properties of the mud. This has made it difficult to examine on the presence of hydrocarbons and flowing properties. Weak oil shows (yellowish fluorescence were recorded in the intervals 903 - 952 m, and at 1746 to 1747 m. No bottom hole temperature at final TD is given on the fact pages, due to no reliable downhole temperature obtained.
Four cores were cut in the original hole: from 905 to 952 m (T

About this data
Norwegian Offshore Directorate (Sodir) FactPages, mirrored nightly and used under the Norwegian Licence for Open Government Data (NLOD). Depths are metres along the wellbore from the kelly bushing unless a row gives its own unit; older cores are filed in feet. A zero the Directorate files for an unmeasured pressure, density, or temperature is shown as a dash.
