The primary objective was to\r\nestablish the presence, quality and fluid content of Jurassic sandstones in\r\nProspects JU2 and JU7 via cores and wire line logs and to evaluate their\r\nproductivity and fluid properties if hydrocarbon bearing. The pre-Cretaceous\r\nwas to be accurately dated via biostratigraphy. The secondary objective was to\r\nverify the presence, quality and fluid content of Permian sandstones in\r\nProspect P2, and if possible to test the margin of the Jurassic JU2-B Prospect\r\nlocated stratigraphically between JU2 and JU7.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eExploration well\r\n2/7-29 was spudded with the jack-up installation "Maersk Guardian" on\r\n18 September 1993 and drilled to TD at 4900 m in mudstones of the Permian\r\nRotliegend Group. A 9 7/8"pilot hole was drilled to 310 m before opening\r\nto 36" to evaluate possible shallow gas. No shallow gas was observed and\r\nthe 30" casing was set at 302 m. A further 9 7/8" pilot hole was\r\ndrilled to 1155 m before opening to 26" and the 20" casing set at\r\n1146 m. The well was drilled with seawater and hi-vis sweeps down to 310 m,\r\nwith bentonite mud from 310 m to 1153 m, and with synthetic oil (ester) based\r\n"AQUAMUL B II EBM" mud from 1153 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eHydrocarbons were\r\nencountered in 129m of gross (49m net) sandstone in the JU2 prospect (Eldfisk Fm.), the\r\nshallower of the Jurassic prospects. Log evaluation established an Oil-Down-To\r\nat 4530 m TVDSS. Mean porosities of 12% and permeability in the range 0.01 to\r\n80 mD were measured from core and log data over the pay zone. The mean reserves\r\nfor the discovery are estimated at 9.3mmbbl (1.48mmcum). Two sand intervals of\r\n12.5 and 19m gross thickness were encountered in the JU7 target. The upper\r\ninterval contained hydrocarbons. A gross sandstone thickness of 46m was\r\nencountered in the Early Permian, although no hydrocarbons were present. \u003c/p\u003e\r\n\r\n\u003cp\u003eA ",
