Tullow and Anadarko in oil find

UK-listed explorer Tullow Oil and US producer Anadarko Petroleum are set to announce they have established a new oil frontier stretching 1,100km along the African coast. The announcement, which could come today, is tied to discoveries at the Venus well Anadarko has been drilling off Sierra Leone. Venus-B lies at the western edge of a geological system that includes large discoveries off Ghana's shores.
