Tullow Oil plc, through its subsidiary, Tullow Ghana Limited, has interests in two exploration blocks in Ghana – Deepwater Tano and West Cape Three Points. Tullow is the operator of the Jubilee field, which straddles both blocks, and lies approximately 60 kilometres off the coast of Ghana. The Jubilee field was discovered in 2007 and First Oil was celebrated on 15 December 2010 following first initial production in November.

Jubilee is a world-class oil field with estimated recoverable resources of up to 1 billion barrels. In addition to Jubilee, these licences hold further exploration potential, which is currently being explored.On the 25 July 2011, Tullow completed the acquisition of the Ghanaian interests of EO Group Limited for $305 million, increasing Tullow’s interest in the West Cape Three Points licence by 3.5% to 26.4% and in the Jubilee field, which Tullow operates, by 1.75% to 36.5%. Other partners in the Jubilee Unit Area are Kosmos Energy (23.49%), Anadarko Petroleum (23.49), the Ghana National Petroleum Company (13.75%) and Sabre Oil & Gas (2.81%). Tullow also has a 49.95% interest in the Deepwater Tano licence which includes the TEN discoveries.

Proposals must be published.

Ample time for consultation must be given before decisions are taken.

Regulatory failures must be handled openly by government.
