The original\r\nprimary objective, as stated in the Operator's Final Well Report from 1972, was\r\nEarly Paleocene to Late Eocene sands, which had a thin oil leg in the three\r\nwells drilled previously. It was\r\nanticipated that appreciably thicker Early Eocene sands would be encountered in\r\nthe oil leg of 25/10-2. Additional prospects were in Middle - Late Eocene\r\nsands, Danian carbonates, and sands of Early Cretaceous, Jurassic or Triassic\r\nage. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe results of the\r\nwell given below is reported with today's knowledge of the area (anno 2003) and\r\ncannot be compared directly with the original objectives.\u003c/p\u003e\r\n\r\n\u003cp\u003e \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 25/10-2\r\nwas spudded with the drilling vessel "Glomar Grand Isle" on 5 August\r\n1970 and drilled to TD at 2191 m (7187 feet) in the Paleocene Lista Formation.\r\nDrilling operations went without mechanical problems and there was no lost time\r\nwaiting on weather. Well 25/10-2 was suspended 25 August 1970 as a well with\r\noil shows. The well was re-entered (25/10-2 R) using "Glomar Grand\r\nIsle" on 2 May 1972 and drilled to a total depth of 3180.6 m (10435 feet)\r\nin basement rock. \u003c/p\u003e\r\n\r\n\u003cp\u003eAfter drilling out\r\nthe plug in the bottom of the casing in the re-entry some difficulty was\r\nexperienced in staying in the old hole.\r\nThe well was drilled to a depth of 2369 m where lost circulation was\r\nencountered. Later the pipe became stuck, with the bottom of the fish at 2213\r\nm, and it became necessary to sidetrack the hole. Six cones were lost in the hole while drilling at 2497 m in the\r\nsidetrack hole; otherwise no problems were experienced. Initial drilling from\r\nthe sea floor to 396 m was with seawater and gel. From 396 m to 1036 m the hole\r\nwas drilled with seawater / Spersene / XP 20 / Salinex s",
