Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 7220/11-2 A is a geological sidetrack to well 7220/11-2. Both wells were drilled to appraise the 7220/11-1 Alta discovery. The main well found gas in Early Triassic sandstones and conglomerate, but no producible oil due to tight formation in the lower part of the reservoir. The objective of 7220/11-2 A was to investigate reservoir quality and confirm the presence of an oil leg on the western flank of the Alta structure.
Operations and results
Appraisal well 7220/11-2 A was kicked off at 635 m in the main well on 3 May 2015. It was drilled with the semi-submersible installation Island Innovator to TD at 2121 m (2071 m TVD) in basement rocks. No significant problem was encountered in the operations. The well was drilled with Aquadril mud from kick-off to TD.
Top of the target reservoir was encountered at 1951.8 m (1901.7 m TVD). The reservoir consists of Early Triassic sandstone and conglomerates, similar as in the main well. The reservoir was oil and gas bearing. The contacts in the 7220/11-1 discovery well were not confirmed; however, pressure points indicated a common fluid system with the main well and with 7220/11-1. The thickness of the reservoir is 102 m TVD, ca 13 m thicker than in the main well. Between base reservoir and top basement, well 7220/11-2 A penetrated a 14 m thick sequence with marl, claystone and dolomite, possibly belonging to the Gipsdalen Group. Oil shows were similar as in the main well bore: on siltstone and sandstones from top Toscana Group to top reservoir, throughout the reservoir, and down to 2079 m in the basement.
Six conventional cores were cut in the interval 1926.6 to 2048.66 m (125.9 m). Recovery for core 1 was 99%, for the remaining co

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.
