    ACCRA, Ghana -- The Sankofa -1A well in the Cape Three Points block offshore Ghana has hit pay, according to the Ghana National Petroleum Corp. (GNPC) and Vitol Upstream Ghana. The well encountered a net hydrocarbon column of approximately 36.3 m (119 ft) comprising a 33-m (108-ft) gas column and 3.2-m (10.5-ft) oil column in Campanian age reservoir sands.

    The success of this well confirms the prospectivity of these Upper Cretaceous reservoir sands, the companies say. The well has now been suspended for possible re-entry. The target reservoir was successfully cored and a full wireline logging program was also run.

    The semisub Blackford Dolphindrilled the well to a total depth of 3,704 m (12,152 ft). This is the first exploration well to be drilled during the first phase (three years) of the three-phased, seven-year exploration period provided for in GNPC’s petroleum agreement with the Government of Ghana.
