Parex Announces Closing of the Cabrestero Block Acquisition, New Oil Discoveries and Record Production

CALGARY, ALBERTA--(Marketwired - June 10, 2013) -

NOT FOR DISTRIBUTION OR FOR DISSEMINATION IN THE UNITED STATES

Parex Resources Inc. ("Parex") (TSX:PXT) announces closing of the Cabrestero Block acquisition and recent drilling success. The company also expects that its second quarter 2013 production to be 15,000-15,500 bopd.

"This year we've consistently stated that our key goal is to demonstrate the sustainability of our business. So far in 2013 we've had two significant discoveries, two material field extensions and continued strong performance on our Kona field. Over the next 2 months we will conduct extended production tests on the new wells to help us evaluate the potential reserves impact and based on that we'll set out our remaining year 2013 production strategy and our first pass at the 2014 capex and production budgets", commented Wayne Foo, President and CEO.

• Q2 2013 Production: We expect that production for the period April 1, 2013 to June 30, 2013 to average 15,000-15,500 bopd, compared to Q1 2013 average of 14,440 bopd and 2012 full year average of 11,407 bopd.
• Cabrestero Acquisition Closed: On May 31, 2013 Parex (block operator) increased its Cabrestero Block working interest from 50 percent to 100 percent through acquiring its partner's working interest for a cash consideration of approximately $12.5 million before adjustments. The block currently has two producing fields, Kitaro and Akira. Parex successfully drilled the Akira-2 appraisal well approximately 700 meters north of Akira-1 and outside of the 2012 GLJ Reserves Report Possible ("3P") mapped area. Akira-2 is currently producing approximately 340 bopd of 14° API oil. Subsequently, the company drilled Akira-3 as a water disposal well. At present, Akira-4 has been drilled to its target depth approximately 850 meters to the northeast of Akira-1 to evaluate a target outside of the 2012 GLJ Reserve Report Probable ("2P") mapped area. After encountering indications of oil pay in the Guadalupe Formation, Akira-4 is being cased and will be completed. Future development plans for the Cabrestero Block include additional infilling drilling and replacement of the temporary rental tanks with an installation of a permanent production facility.
• Tarotaro (Block LLA-34, WI 45%): The Tarotaro-1 exploration well (non-operated) was drilled to a target depth of approximately 11,000 feet. The well was cased after encountering indications of oil pay in the Mirador and Guadalupe formations. The Guadalupe formation is the deeper and first zone to be tested and was perforated over a 60 foot interval. Testing has been underway for the last 22 hours with the use of an Electric Submersible Pump ("ESP") and the average oil rate over the last 12 hours has been 1,700 bopd at a water-cut of 3.5 percent. Parex believes the current measured water-cut rate is due to remaining residual work-over fluids in the wellbore. A total of 1,087 bbls of oil and 186 bbls of water have been recovered from the test and subsurface pressure recorders installed on the ESP indicate a drawdown of under 15 percent. Lab analysis will be required to confirm the API of the produced oil but Parex anticipates an API of between 13 and 17 degrees based on production from the Guadalupe formation at surrounding fields Tua and Max. Parex expect Tarotaro-1 to be immediately placed on a long-term production test. Tarotaro is a new independent discovery outside the current 2012 GLJ Reserve Report and is approximately 6 kilometers north-east from the Tua discovery. The operator is currently drilling the Tarotaro-2 appraisal well and we anticipate that additional delineation drilling will be required to find and test the limits of the field;
• Las Maracas (Block Los Ocarros, WI 50%): The oil treatment plant has been commissioned. Parex expects initial total field production between 10,500-11,000 bopd for the balance of 2013 and will re-evaluate production targets based on well performance and results of future appraisal/development drilling;
• Adalia (Block LLA-30, WI 100%): As reported April 8, 2013, the Adalia-1 exploration well was flow tested from the C5 Formation over a 32 hour period at an average rate of 1,980 bopd and 38° API oil was recovered during the test. Civil works including road construction have been completed and Parex expects to commence a long-term production test in late June 2013. Future Adalia appraisal drilling will be largely dependent on well performance during the long-term test;
• Tua (Block LLA-34, WI 45%): The Tua-4 and Tua-5 wells were drilled as Guadalupe delineation wells outside of the 2012 GLJ Report Possible ("3P") mapped area. On March 25, 2013, Tua-5 began producing at a rate of approximately 1,000 bopd of 16° API oil from the Guadalupe Formation. Tua-4 was drilled to appraise the southern flank of the Basal Guadalupe structure and is producing at an initial rate of approximately 850 bopd. We anticipate that additional delineation drilling throughout 2014 will be required to find and test the limits of the field;
• Celeus (Block LLA-17, WI 40%): The Celeus Sur-1 exploration well was spud May 23, 2013 and was drilled to a target depth of 10,700 feet to evaluate the C7 and Gacheta formations. The well is being cased and Parex expects to test the well. Recall that the Celeus-1 produced 200 bopd from each of the Gacheta and C7 formations on natural flow. Parex is planning to alternate the use of the Celeus-1 and Celeus-Sur-1 wells by producing one well while the other well operates as a disposal well to minimize operating costs. Test results from Celeus Sur-1 will determine which well will be placed on production first. Celeus-1 production is currently shut-in;
• La Casona (Block El Eden, WI 60%): On May 30, 2013 the La Casona-2 well was spud and is currently drilling at approximately 11,150 feet. The target depth of the well is 16,500 feet approximately 700 meters northeast of La Casona-1 to further evaluate the Une, Gacheta and Mirador (untested in Las Casona-1) formations. The construction of the long-term test facility at La Casona-1 is ongoing and we expect that the La Casona-1 well will be placed on production towards the end of the third quarter of this year;
• Kona (LLA-16, WI 100%): Kona continues to produce at 5,000-6,000 bopd. During May 2013, Kona Norte-1 and Kona Sur-1 were placed on extended production tests at a combined rate of approximately 1,400 bopd. This deliverability will be incorporated in setting future Kona field production targets. The Kona field has cumulatively produced over 5 million barrels of oil and therefore the field is subject to an additional "High Price Share" royalty of approximately 20 percent. As such, Parex continues to utilize the Kona field as a swing producer within the company's portfolio, enhancing our ability to achieve quarter over quarter production growth and deliver sustainable production growth.
