It was prognosed\r\napproximately 40 m below the distinct Late Cretaceous Top Ekofisk Formation\r\nreflector. \u003c/p\u003e\r\n\r\n\u003cp\u003eReservoir units were\r\nexpected in several intervals, some in pressure communication and some not. A\r\npossible secondary target of sediment fill in the interval between the Shetland\r\nGroup and the basement topography would be penetrated before reaching TD in\r\nmetamorphic rocks. However, this possible wedge was defined on a poor seismic\r\nresponse and could represent intra basement reflectivity.
