TORONTO, April 29,  2013 /PRNewswire/  - Pacific Rubiales  Energy Corp.  (TSX: 
PRE; BVC: PREC; BOVESPA: PREB) is pleased  to announce the closing of the  CGX 
Energy Inc. (TSXV: OYL) ("CGX  Energy") private placement financing on  April 
26, 2013. The Company subscribed for  350 million units ("Units") at a  price 
of Cdn.$0.10 per Unit for an aggregate price of Cdn.$35 million. Each Unit is
comprised of one common share in the capital of CGX and one whole common share
purchase warrant of CGX with an exercise price of Cdn.$0.17.

As a result of the private placement, Pacific Rubiales owns approximately  63% 
of the issued and outstanding common shares in the capital of CGX Energy on  a 
non-diluted basis and approximately 75%  on a fully-diluted basis. The  board 
of directors of CGX  Energy is comprised of  eight directors of which  Pacific 
Rubiales has nominated five directors - being Ronald Pantin, Serafino  Iacono, 
José Francisco  Arata,  Marino Ostos  and  Dennis  Mills. The  new  board  of 
directors of CGX has appointed Serafino  Iacono as Co-Chairman, Dewi Jones  as 
Chief Executive Officer and Michael Galego as General Counsel and Secretary.

Ronald Pantin, Chief Executive Officer of Pacific Rubiales, commented:  "This 
investment will allow us  to expand and deepen  the Company's position in  the 
highly prospective offshore Guyana oil  play. We consider CGX Energy's  large 
acreage position in Guyana to be a premier world-class exploration asset in an
offshore basin with analogous geology to West Africa, Brazil and Venezuela.

"On the Corentyne Block, DeGolyer and MacNaughton in a resource report for CGX
Energy effective December  31, 2012, estimated  mean Prospective Resources  of 
1,522 MMbbl of liquid hydrocarbons (779 MMbbl of oil and 743 MMbbl condensate)
and 7,889 Bcf of non-associated and  associated natural gas, contained in  six 
exploration opportunities.  Additionally,  the  USGS in  its  report  entitled 
"Assessment of  Undiscovered  Conventional  Oil and  Gas  Resources  of  South 
America and Caribbean, 2012" calculated 12,494 MMboe and 18,284 Bcf of yet  to 
find oil and gas,  respectively, for the  Guyana-Suriname basin. Both  reports 
emphasized the great upside exploration potential of this basin.

"This investment  is  well-aligned  with the  Company's  technical  strengths, 
strategy of early stage large resource  capture and objective of building  the 
leading Latin American independent explorer and producer of hydrocarbons."

Boe's may  be misleading,  particularly if  used in  isolation. The  Colombian 
standard is a boe conversion ratio of 5.7 Mcf:1 bbl and is based on an  energy

Prospective Resources are  those quantities  of oil  and gas  estimated to  be 
potentially  recoverable  from  undiscovered   accumulations.  There  is   no 
certainty that the Prospective Resources  will be discovered. If  discovered, 
there is  no certainty  that it  will be  commercially viable  to produce  any 
portion of  the  Prospective  Resources. Application  of  any  geological  and 
economic chance factor  does not  equate Prospective  Resources to  Contingent 
Resources or reserves.
