     Wireline evaluation program confirms oil discovery in the Kangaroo-1
        exploration well, Karoon blocks, offshore Santos Basin, Brazil

TORONTO, Jan. 30, 2013

TORONTO, Jan. 30, 2013 /PRNewswire/ - Pacific Rubiales Energy Corp. (TSX:PRE;
BVC: PREC; BOVESPA: PREB) announced today that a wireline evaluation program
has confirmed the previously announced light oil discovery in the Kangaroo-1
exploration well 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 (ANP)).

As announced in an  operational update news release  today by the operator  of 
the blocks,  Karoon  Gas  Australia  Ltd. (ASX:  KAR),  (see  Karoon  website: 
www.karoongas.com.au), the wireline evaluation of the Eocene discovery zone in
the Kangaroo-1 well, including petrophysical logs, core samples, fluid samples
and flow tests all conducted on wireline, is nearing completion.

The wireline data confirms a 25 meter (gross) light oil column sitting above a
well-defined oil water contact in the well. Multiple oil samples measuring 42
degree API were recovered to surface from two separate intervals in the  zone. 
Petrophysical well  logs indicate  porosities  in the  25  to 32%  range,  and 
permeabilities of 100 to 300  millidarcies have been determined from  pressure 
flow tests. Multiple wireline core samples  collected across the zone and  to 
be analyzed  in  a laboratory  will  provide additional  measurements  of  the 
reservoir zone's porosity and permeability characteristics.

"Although not the  primary objective,  this is  an exciting  discovery in  our 
first exploration  well drilled  on the  Karoon blocks  in Brazil",  commented 
Ronald Pantin, Chief Executive Officer of Pacific Rubiales. "At this stage we
believe that the wireline testing and evaluation indicates that the Kangaroo-1
Eocene reservoir is of good  quality, has the potential  to flow light oil  at 
commercial rates, and  we feel  very comfortable  that this  is a  significant 
discovery. We are proceeding with plans to drill an appraisal well to further
delineate the extent of the Kangaroo reservoir. In addition, the discovery of
an oil bearing reservoir  and an effective trap  in the Eocene de-risks  other 
undrilled Eocene structures identified on the Karoon blocks."

When the current wireline operations are completed, the operator will relocate
the rig to drill  the Emu-1 exploration well  to evaluate blocks S-M-1102  and 
S-M-1037, where  the Company  also holds  a 35%  participating interest  (also 
subject to approval by the ANP).

Karoon is currently working to acquire a second rig to drill an appraisal well
(Kangaroo-2) at  a  more  optimal  up-dip  location  for  full  reservoir  and 
production testing  of the  discovery.  The appraisal  well would  expect  to 
penetrate a larger hydrocarbon column at the crest of the structure where  the 
gross reservoir section could be as thick as 350 meters and contain  sandstone 
packages with better petrophysical characteristics.
