  • Wellbore history
    General
    Well 31/6-6 was drilled in the Troll East gas province. It was designed to test possible gas accumulations in the Late to Middle Jurassic sandstones and to test the quality of a reservoir siltstone in the Heather Formation.
    Operations and results
    Well 31/6-6 was spudded with the semi-submersible installation Deepsea Bergen on 22 May 1984 and drilled to TD 2293 m in the Late Triassic Hegre Group. No significant problem was encountered in the operations. The well was drilled with spud mud down to 716 m, with KCl/polymer mud from 716 m to 1771.5 m, and with pre-hydrated bentonite/CMC mud from 1771.5 m to TD.
    The well encountered gas from top Heather reservoir at 1516 m to a GWC at 1568.5 m, 7.5 m into the Sognefjord Formation. No oil shows were reported from the well. Nine conventional cores were cut in the interval 1525 m to 1771.5 m in the Middle to Late Jurassic. FMT samples were taken at 1571.8 m and 1576.5 m in the Sognefjord Formation. Both contained formation water and mud filtrate.
    The well was completed on 29 July 1984 as a gas appraisal.
    Testing
    Two drill stem tests were performed in the well. DST 1A tested 1562 m to 1567.5 m in the Sognefjord Formation sandstone. It produced maximum 779 x 10 Sm3 gas /day on a 64/64" choke. DST 2 from 1523 m to 1536 m in the Heather Formation siltstone showed a very low production rate, 10.7 x 10 Sm3/day. The reservoir temperature was 62.5 deg. C in DST 1A and 58 deg. C in DST 2.

    Pressure plots
    The pore pressure data is sourced from well logs if no other source is specified. In some wells where pore pressure logs do not exist, information from Drill stem tests and kicks have been used. The data has been reported to the NPD, and further processed and quality controlled by IHS Markit.
