Wellbore history
GeneralWell 6407/9-7 was located on the crest of the "Husky" structure approximately 11 km NNE of Draugen well 6407/9-2.The main objectives of the well were: to evaluate the hydrocarbon potential of the Middle Jurassic sandstones of the "Husky" prospect; to evaluate the Early Jurassic sands; to fulfil the work obligation of the licence by drilling a second exploration well into the Triassic.Operations and resultsWildcat well 6407/9-7 was spudded with Wilh. Wilhelmsen semi-submersible installation Treasure Scout on 26 April 1988 and drilled to TD at 2561 m in the Triassic Red Beds. The well was drilled with Seawater and hi-vis pills down to 810 m and with KCl/Polymer mud from 810 m to TD. The drilling proceeded without problems. No shallow gas was encountered.The target Middle and Early Jurassic reservoir sands were well developed, particularly in the Garn Formation. There were no signs of hydrocarbons, either within the Jurassic sequence or in the overlying section. The well was considered a conclusive dry test of the Husky structure.No cores were cut and no fluid samples were taken. The well was permanently abandoned on 25 May 1988 as a dry well.TestingNo drill stem test was performed -

Pressure plots
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.Pressure plots Document nameDocument formatDocument size [MB]pdf0.30
