Irish oil company Tullow Oil says it is close to declaring its Enyenra and Tweneboa development a commercial proposition, after drilling of the Enyenra-3A appraisal well, in the Deepwater Tano licence offshore Ghana, encountered oil.Pressure data indicates that the Enyenra-3A well has confirmed an up-dip extension of the Enyenra oil field, and confirms a continuous oil column of at least 365 metres. The oil at Enyenra-3A is in static pressure communication with both the Owo-1 discovery well and the Enyenra-2A appraisal well, the company said.The company intends to subsequently drill the Enyenra-4A well to further appraise the down-dip extent of the field. The Enyenra-5A well is then likely also to be drilled north of Enyenra-3A to test the ultimate up-dip extent of the field."Although the ultimate extent of the fields are yet to be fully determined, confirmation of this up-dip extension and long oil column in Enyenra is very encouraging," said Tullow's exploration director, Angus McCoss. Tullow has a 49.95% interest in the Deepwater Tano licence, and is partnered by Kosmos Energy (18%), Anadarko Petroleum (18%), Sabre Oil & Gas (4.05%) and the Ghana National Petroleum Corporation (GNPC) (10% carried interest). Elsewhere in West Africa, Tullow now expects to announce the result of the Montserrado-1 well offshore Liberia during October.--jh
