Indonesia

Premier announces the latest results from the 2006 Indonesian drilling programme
in Natuna Sea Block A.

West Lobe

Whilst drilling the West Lobe-1 well, one of the four development wells
currently being drilled as part of the Anoa Field West Lobe development, a 100
foot hydrocarbon bearing interval was encountered in a shallower horizon above
the main producing reservoir.  An evaluation is under way to establish the
significance of this success which is likely to require further appraisal.

Central Lobe

In addition, a further appraisal well has been drilled into a new fault block in
the Anoa Field.  Results have confirmed the presence of a 67 foot column, with
an overlying 80 foot gas column.  Evaluation is ongoing, however this result has
the potential to increase significantly oil production at the Anoa field.

Premier's Chief Executive, Simon Lockett, said:

"The success here is positive news for our key Anoa asset in Natuna Sea Block A
where next year we will be drilling a further five wells.  In line with our
strategy, this is further evidence of our ability to add reserves from within
our existing producing portfolio."
