Indonesia: Premier Reports Successful Well Testing

Premier Oil announces that the Lama formation within the Anoa field on Natuna Sea Block A (Indonesia) has been successfully tested. The WL-5 development well on Natuna Sea Block A was deepened to a total depth of 11,012 feet to investigate the exploration potential of the Lama Formation within the Anoa Field.

The well encountered approximately 300 feet of fractured Lama Sandstones.

The Lama formation has now been tested over the interval 10,658 feet MD to 10,770 feet MD and flowed gas at a rate of 17 mmscfd through a 48/64 inch choke. The results of the test will be integrated with the log and seismic data to determine the ultimate recoverable resource of this deeper reservoir that will be produced through the Anoa facility.

Premier operates and holds a 28.667% interest in Natuna Sea Block A and is partnered by KUFPEC Indonesia (Natuna) BV, Hess and Petronas.

Simon Lockett, Chief Executive Officer, commented:

“We are very encouraged by this successful well test which has opened up deeper potential on this prolific gas block.”
