The first\r\nwell, 2/4-14 (1988-89), penetrated an overpressuried reservoir, which was\r\ntested in an updip position by the well 2/4-16 / 2/4-16R. The latter well did\r\nnot confirm the reservoir model. It was then concluded that the zone of main\r\ninterest had to be situated in younger strata, preserved downdip to the east.\r\nWell 2/4-14 was sitting approximately at the pinch-out point of the untested\r\nwedge. Well 2/4-18 was drilled to test this model.\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 2/4-18 was spudded with the\r\nsemi-submersible installation Treasure Saga on 26 April 1993.
