GeoPark Announces New Tigana Norte 1 Oil Discovery and Tigana Field Extension in Block Llanos 34 in Colombia

GeoPark Limited (“GeoPark”) (NYSE: GPRK), the Latin American oil and gas explorer, operator and consolidator with operations and producing properties in Chile, Colombia, Brazil and Argentina, today announces the discovery of the Tigana Norte 1 oil well on its Llanos 34 Block in Colombia. GeoPark is the Operator of and has a 45% working interest in the Llanos 34 Block.

GeoPark drilled and completed the Tigana Norte 1 well to a total depth of 12,141 feet. A test conducted with an electrical submersible pump in the Guadalupe formation, at approximately 11,557 feet, resulted in a production rate of approximately 1,061 barrels of oil per day (“bopd”) of 14.6 ° API, with a 0.49% water cut, through a choke of 24/64 inches and well head pressure of 235 pounds per square inch. Further production history will be required to determine stabilized flow rates of the well.

Production and reservoir analyses from the Tigana 1, 2 and 3, Tigana Sur 1 and Tigana Norte 1 wells on the Llanos 34 Block now indicate that three previously delineated fields and prospects form part of a single larger combined (structural and stratigraphic) trap and field, productive from the Cretaceous Guadalupe and Tertiary Mirador formations. The field is currently producing over 8,500 bopd gross from the 5 wells drilled and completed to date. The Company is carrying out further development and appraisal drilling this year on the Tigana Field complex, including the Tigana Sur Oeste 1 well that is currently being completed. Preliminary results suggest that the stratigraphic component of the trap could enhance the exploration potential of the Llanos 34 Block area.
