Located between Dumai and Sibolga in Sumatera, the Tonga PSC covers 2,607 km2 and was awarded in 2007 for 30 years. Tonga 1 well has been tested at 700 bbls per day, several additional opportunities identified in surrounding areas through seismic interpretation. The development plan includes acquisition of further 2D and 3D seismic to delineate various hydrocarbon accumulations within the PSC.

Upon confirmation from the seismic programme, drilling at Tonga 2 and Tonga 3 is due to commence in the second half of 2010. Some 4.5 million bbls of 2C oil resources have been identified in the block.
