  2nd Successful Commercial Discovery at High Island A268, Gulf of
                               Mexico
               Production from field by mid-September

Providence, along with its High Island A268 partners, is very pleased
to announce that it has successfully drilled a 2nd well at High
Island A268 in the Gulf of Mexico. The A2 exploration well, in which
Providence holds a 5% working interest, was drilled from the newly
installed High Island A268 'A' platform using the Todco 250 jack-up
drilling unit. The A2 well TD bottom hole location is approximately 1
mile east of the A1 well discovery, announced in January 2007.
The A2 well was drilled targeting new potential gas accumulations,
with pre-drill gross recoverable volumes estimated at between 3.5 to
5.8 BSCFG. The actual drilling results met pre-drill expectations
with the discovery of 2 high quality gas bearing sands with a
combined net gas pay equal to the pre-drill expectations. Average
porosities derived from well log analysis and sidewall core data
indicate good quality sands and therefore is likely to provide
significant gas flow rate potential.
A production liner has now been set across the reservoir intervals,
and completion operations are currently underway. First gas is
expected to be produced from the A2 well towards the end of August
2007.  The A2 well will produce gas from the lower reservoir first.
Once the reserves from the lower reservoir have been fully exploited,
the reserves in upper reservoir will then be produced, maximizing
overall gas recovery in this well.
After completion of the A2 well, the Todco 250 jack up drilling unit
will move back to the A1 well and will commence completion operations
there. The A1 well is expected to be on production in mid September
2007.

Commenting on this development, Tony O'Reilly Jnr. Chief Executive
said:


"We are very pleased with this additional discovery at High Island.
Following on from the successful gas discovery at High Island A268 in
January 2007, we immediately elected to move the discovery into
fast-track development.   A production platform, with the capability
to process the gas and export it to market via nearby existing
infrastructure, has been successfully installed on High Island A268
to process gas from the A1 well.
"The inclusion of gas from the A2 well is an added bonus for the
partners involved as the economic justification for the production
platform was based solely on production from the A1 well.
"All going according to plan, we would expect commercial production
of gas from both wells at High Island A268 in mid-September 2007,
thereby validating our strategy to enter into development/production
opportunities in the Gulf of Mexico, where the timelines are short".

The A1 well, was drilled in the December 2006 through January 2007
period in 165 feet of water using the TODCO 207 jack-up drilling
unit. The well was drilled to a deviated total depth of 8,172 ft
TVDSS. The well was drilled on a Tertiary-aged gas-condensate target
with pre-drill most likely recoverable resource estimate of 10 BSCFE.
The OCS-G 22268 A2 exploration well, was drilled in 165 feet of water
from the newly installed High Island A268 'A' platform using the
Todco 250 jack-up drilling unit. The A2 well TD bottom hole location
is approximately 1 mile east of the A1 well discovery, announced in
January 2007. Drilled to a deviated total depth of 6,863 ft TVDrkb,
the A2 well was targeting new potential gas accumulations, with
pre-drill gross recoverable volumes estimated at between 3.5 to 5.8
BSCFG.
