The salt plug is\r\nlocated in the cross-junction between the four blocks 1/6, 1/9, 2/4, and 2/7.\r\nThe objective was to establish if Danian - Late Cretaceous carbonates were\r\npresent on the salt plug. If present the carbonates would be evaluated. \u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWell 2/7-12 was spudded with the semi-submersible\r\ninstallation Dyvi Beta on 17 December 1978 and drilled to TD at 1832 m in the\r\nLate Permian Zechstein Group. The well was drilled with salt-based mud,\r\npossibly with some diesel addition according to geochemical analyses, in the\r\ninterval from 1402 m to TD. Several thin gas charged siltstone stringers were\r\npenetrated between 433 m and 835 m.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe salt (Permian Zechstein Group) was\r\nencountered at 1686 m. The well did not encounter any Danian -Late Cretaceous\r\ncarbonates on top of the salt. Oil shows (fluorescence, cut, stain or\r\ncombinations) were recorded on SWC's and cuttings at 114.5 - 445 m (sandstone),\r\n731 - 810 m (claystone with trace of fine sandstone), and scattered on\r\nclaystone, shale, and limestone from 1469 m to 1679 m. The resistivity log indicated\r\na probable hydrocarbon zone from 416 to 433 m in a shallow sand. It was not\r\npossible to calculate reliable porosity from the sonic log, but a DST confirmed\r\nminor amounts of oil.\u003c/p\u003e\r\n\r\n\u003cp\u003eNinety sidewall cores were attempted and\r\nseventy-one were recovered from the overall interval 1417.3 to 173.7 m. No\r\nconventional cores were cut and no wire line fluid samples taken in this well.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was permanently abandoned on 30\r\nJanuary 1979 as a dry well with shows.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eOne drill stem test was performed through\r\nperforations at 416.7 - 425.8 m.
