GeoPark Announces Further Expansion of Jacana Oil Field in Colombia Following New Successful Appraisal Drilling

GeoPark Limited (“GeoPark” or the “Company”) (NYSE: “GPRK”), a leading independent Latin American oil and gas explorer, operator and consolidator with operations and growth platforms in Colombia, Chile, Brazil, Argentina, and Peru¹, today announced the successful testing of the Jacana 6 appraisal well in the Jacana Oil Field in the Llanos 34 Block (GeoPark operated with a 45% working interest) in Colombia.

GeoPark drilled and completed the Jacana 6 appraisal well to a total depth of 11,684 feet. A test conducted with an electric submersible pump in the Guadalupe formation, across multiple sand units, resulted in a production rate of approximately 1,800 bpd of 16 degrees API, with a 17% water cut, through a choke of 38/64 mm and wellhead pressure of 80 pounds per square inch. Additional selective interval testing and production history are required to determine the stabilized flow rate and water cut source. Surface facilities are in place and the well is already in production.

¹Transaction executed with Petroperu on October 1, 2014 with final closing subject to Peru Government approval.
