  • Wellbore history
    General
    Well 7121/5-2 is located ca 10 km northeast of the Snøhvit Field. The purpose of the well was to test the hydrocarbon accumulation on the Beta-structure in sandstones of the Early to Middle Jurassic Stø-formation.
    Operations and results
    The well was spudded with the semi-submersible installation Ross Isle on 26 May 1986 and drilled to TD at 2543 m in Late Triassic sediments (Rhaetian age). The well was drilled with seawater and hi-vis pills down to 850 m, with gypsum/polymer mud from 850 m to 1977 m, and with gypsum/polymer/NaCl mud from 1977 m to TD.
    Hydrocarbon bearing Middle Jurassic sandstones in the Stø Formation were encountered at 2323 m. The gas-bearing zone extends from 2323 m to 2346 m. The gas zone is sealed from the underlying oil zone by a 6 m thick dense shale layer, which prevents the exact location of a gas/oil contact. The oil-bearing zone extends from 2352 m 2358.5 m. The oil water contact at 2358.5 m was picked both from logs and core data. Three cores were cut in the Stø formation (2324 m to 2400 m). A total of 9 FMT runs were performed; two to obtain pressure points and 7 to obtain segregated samples. The first run resulted in 32 pre test pressure points out of 38 attempts, in the interval 2323.5 m to 2369.0 m. Eighteen points were taken in the gas zone, 6 in the tight zone, 4 in the oil zone and 4 were in the water zone. The second run resulted in 9 pre test pressure points of nine attempts in the interval 2358 m to 2361 m. Seven attempts to obtain segregated samples resulted in 5 good samples, two at 2355 m, one at 2326 m, and two at 2353.5 m.
    The well was permanently abandoned on 6 June 1986 as an oil and gas discovery.
    Testing
    Due to the presence of hydrogen sulphide in the well, no tests were performed.

    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.
