Brønnhistorie
GeneralWell 11/9-1 is located in the Horn Graben far to the east in the North Sea towards the Skagerrak Sea, ca 15 km from the Danish border. It was located near the top of a saliferous structure in order to explore the whole Triassic series in the most favourable structural position. The structure is potentially large, but since all horizons above the Jurassic level were expected to crop out on the seabed the objective horizon was Lower Middle Triassic carbonaceous shales. These shales were seen both as source rock and seal for hydrocarbons in underlying sandstones (basal Triassic Brockelschiefer). No other objectives were defined for this well.Operations and resultsWildcat well 11/9-1 was spudded with the semi-submersible installation Deepsea Driller on 16 January 1976 and drilled to TD at 1972 m, 42 m into Late Permian Zechstein salt. The well was drilled water based with spud mud down to 660 m and with ferrochrom lignosulphonate mud (FCL) from 660 m to TD.Drilling was without returns to 145 m. From there red sandstones and variegated shales made up a very thick Triassic interval (1785 m). The Triassic contained reservoirs as usual but no obvious sealing intervals were seen. Moreover, no potential source rocks were encountered. No shows of gas or oil were recorded during drilling and the different reservoirs were water bearing from the logs. No conventional core was cut and no fluid sample taken. Forty sidewall cores were retrieved in two runs in the interval 737 m to 1962 m.The well was permanently abandoned on 28 February 1976 as a dry hole.TestingNo drill stem test was performed. -
