    "wlbHistory" : "\u003cp\u003eWildcat well 6306/5-1 was drilled ca 190\r\nkm West of the town Trondheim, on the Klakk Fault Complex, which forms the\r\nborder between the FrØya High and the MØre Basin. The two main objectives were\r\nto test the hydrocarbon potential of two Palaeocene prospects: the Eirikson\r\nprospect and the Nansen prospect. When drilled these prospects were prognosed\r\nas the Heimdal Formation sandstone and a new informal "Skalmen Formation\r\nsandstone", respectively. Only the Skalmen Formation was confirmed by the\r\nwell. Later this formation has been encountered in other wells in the area as\r\nthe (informal) Egga Formation. \u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWildcat well 6306/5-1 was spudded with\r\nthe semi-submersible installation Deepsea Trym on 8 June 1997. Operations went\r\nwithout significant problems down to the 8 1/2" section. This section was\r\ndrilled from 1300 m to 1751 m, top of the Egga reservoir. This was found to be\r\nsignificantly over pressured and a large gain was taken. The well was shut-in\r\nand steps were taken to kill the well. The operation was complicated by the\r\ndiscovery that the pipe was stuck. The string was finally cut at 1477 m, and a\r\ncement plug was set to be used as kick-off plug for a sidetrack around the\r\nfish. The sidetrack was kicked off at 1365 m and drilled to TD at 2050 m in the\r\nLate Cretaceous Kvitnos Formation without further problems. The well was\r\ndrilled with bentonite and seawater down to 1001 m and with ANCO 2000 mud from\r\n1001 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eNo shallow gas or boulder beds were\r\nencountered in the uppermost well section. The well penetrated mainly clays and\r\nclaystones in the Nordland, Hordaland and Rogaland groups with minor sands\r\ndeveloped and limestone stringers present. The prognosed Heimdal Formation\r\nsands were not present. Top Egga sand was reached at 1751 m and was 12 m thick.\r\nThe lithology of the Egga sand was mainly a clean sandstone divided in two by a\r\ncalcareous clay stone. Top of the Egga reservoir was re-penetrated in the\r\nsidetrack at ",
