The company said that the Bonneville discoveries were in "excellent quality reservoirs" with "average porosities of approximately 30%".
The estimated oil in place from the Bonneville discoveries was approximately 30m barrels, in line with pre-drill predictions.
In addition to the oil discovery at Bonneville, the company said that the Matang-1 exploration well in Indonesia, in which Premier has 41.67% equity, had discovered gas and would be tested.
The company said that testing of the Luno II discovery in Norway, in which Premier has 30% equity, had commenced and results would be expected before the end of the month.
Simon Lockett, Chief Executive Officer, commented: "We are delighted with the strong start to our 2013 exploration drilling programme with the previously announced discovery at Luno II and now the discoveries at Bonneville and Matang."
He added: "We look forward to the outcome of the test programmes at Luno II and Matang while the Bonneville discoveries will be tied back to our important Catcher area development, which is targeted for project sanction by year-end."
