Pacific Rubiales Provides Update On The Quifa Field Arbitration Process

   Pacific Rubiales Provides Update On The Quifa Field Arbitration Process

PR Newswire

TORONTO, Feb. 21, 2013

TORONTO, Feb. 21, 2013 /PRNewswire/ - Pacific Rubiales Energy Corp. (TSX: PRE;
BVC: PREC;  BOVESPA:  PREB)  announced  today  an  update  on  the  previously 
disclosed and ongoing arbitration process  associated with its operated  heavy 
oil production  interests in  the  Quifa block,  south Llanos  basin,  onshore 
Colombia.

The Company's share  of production before  royalties from the  Quifa block  is 
60%;  however,  this  participation  decreases  once  the  high-prices  clause 
("PAP"), which is stipulated in the Quifa Association Contract, is triggered.
Ecopetrol S.A., the Colombian  National Oil Company,  holds the remaining  40% 
interest in the Quifa block.

On September  27,  2011, Ecopetrol  and  the  Company agreed  to  commence  an 
arbitration process to settle certain differences in the interpretation of the
PAP clause in the Quifa Association Contract and its effect on the  production 
split as between the companies. While the arbitration process runs its course,
both companies  agreed  to  apply  the formula  of  the  Agencia  Nacional  de 
Hidrocarburos ("ANH"). Pacific Rubiales has been recognizing the ANH  formula 
in its financial statements since the third quarter 2011.

The arbitration process is currently ongoing  and is not expected to  conclude 
and a  decision  rendered until  next  month, contrary  to  reports  currently 
circulating in national and international news media.

The Company  believes  that it  has  strong  legal reasoning  to  support  its 
position in respect to the arbitration process.

Pacific Rubiales, a  Canadian company and  producer of natural  gas and  crude 
oil, owns 100% of  Meta Petroleum Corp., which  operates the Rubiales,  Piriri 
and Quifa heavy oil fields  in the Llanos Basin,  and 100% of Pacific  Stratus 
Energy Colombia Corp., which  operates the La Creciente  natural gas field  in 
the northwestern area of Colombia. Pacific Rubiales has also acquired 100% of
PetroMagdalena Energy Corp., which owns light oil assets in Colombia, and 100%
of C&C Energia  Ltd., which owns  light oil  assets in the  Llanos Basin.  In 
addition, the Company has a  diversified portfolio of assets beyond  Colombia, 
which includes producing  and exploration assets  in Peru, Guatemala,  Brazil, 
Guyana and Papua New Guinea.

The Company's common shares trade on the Toronto Stock Exchange and La Bolsa
de Valores de Colombia and as Brazilian Depositary Receipts on Brazil's Bolsa
de Valores Mercadorias e Futuros under the ticker symbols PRE, PREC, and PREB,
respectively.

than statements  of  historical  fact,  that  address  activities,  events  or

current expectations or beliefs of the Company based on information  currently 
available to the Company. Forward-looking  statements are subject to a  number 
of risks and uncertainties that may cause the actual results of the Company to
differ materially from those discussed in the forward-looking statements,  and 
even if such actual results are realized or substantially realized, there  can 
be no assurance that they will  have the expected consequences to, or  effects 
on, the Company. Factors that could  cause actual results or events to  differ 
materially from current expectations include, among other things:  uncertainty 
of  estimates  of  capital  and  operating  costs,  production  estimates  and 
estimated economic  return; the  possibility  that actual  circumstances  will 
differ from  the estimates  and assumptions;  failure to  establish  estimated 
resources or reserves; fluctuations in petroleum prices and currency  exchange 
rates;  inflation;  changes  in  equity  markets;  political  developments  in

put on such statements due to the inherent uncertainty therein.

In addition, reported production levels  may not be reflective of  sustainable 
production rates and future  production rates may  differ materially from  the 
production rates reflected in this press release due to, among other  factors,
