Pacific Rubiales confirms oil discovery on the Karoon blocks, offshore Brazil

January 24, 2013

TORONTO, Jan. 24, 2013 /PRNewswire/ – Pacific Rubiales Energy Corp. (TSX: PRE;
BVC: PREC; BOVESPA: PREB) confirmed today the discovery of light oil at
the Kangaroo-1 exploration well drilling on block S-M-1101, in the
Santos basin, offshore Brazil.  The well was drilled as part of an
agreement announced by the Company on September 18, 2012, as a minimum
work commitment for both the S-M-1101 and S-M-1165 blocks, where the
Company holds a 35% participating interest (subject to approval by
Brazil’s Agência Nacional do Petróleo, Gás Natural e Biocombustíveis

As announced by the operator of the blocks, Karoon Gas Australia Ltd.
(ASX: KAR), (see Karoon website: www.karoongas.com.au), the Kangaroo-1 well has been drilled to a depth of 3,049 meters and
the presence of a light oil column has been confirmed by mudlog,
wireline petrophysical and MDT pressure data in Eocene aged rocks.  A
gross column of 25 meters and an oil / water contact is established
from pressure data interpretation.

The well intersected the Eocene reservoir section 300 metres down dip
from the trap crest as interpreted on seismic mapping by Karoon.  A
potential gross hydrocarbon column of approximately 350 metres is
estimated by Karoon for the entire trip.

As this was not the primary target at the Kangaroo-1 well, the discovery
of oil in the Eocene reservoir at the Kangaroo-1 well provides
additional information with respect to other potential prospects within
the Karoon blocks.  Also, the well exhibited good oil shows at the base
of the Miocene aged carbonate layers, but these are still under a
detail evaluation to determine their potential.

A wireline program is currently underway with full results expected in
the coming days.  A drill stem test program will be assessed on
completion of the wireline evaluation.  The full evaluation program for
the well is expected to continue through February.  Pacific Rubiales
expects to issue an additional news release providing further technical
details relating to these drill results.
