Pacific Rubiales Energy Corp. has received independent reports relating to the progress of its proprietary Synchronized Thermal Additional Recovery (STAR) enhanced oil recovery pilot project in the Quifa SW heavy oil field. The reports include estimates of the Original Oil In Place ("OOIP") for the project, which combined with the accumulated production from the area since the inception of the project, allows the Company to estimate that at least a doubling of the recovery factor has been achieved from commencement of air injection in February, 2013 to date.

Ronald Pantin, Chief Executive Officer of the Company, commented,"The estimates from the independent engineers of the OOIP and the drainage areas that will be affected by the pilot test area, the cumulative oil volumes produced to date and the sustained thermal ignition of the reservoir and successful synchronization of the producing pilot wells, have led Pacific Rubiales to estimate at least a potential doubling the recovery factor can be achieved by STAR. These results represent an important inflection point in the path to successful commercial application of STAR in one of Colombia's most important heavy oil fields.

"Based on these results, the Company is planning on converting two contiguous well clusters in the pilot test area, which are currently producing on primary flow, to STAR before the end of 2013. Additionally, the Company has initiated planning for full commercial rollout of STAR in the Quifa SW field beginning in 2014.
