GeoPark Announces Four New Drilling Successes in Colombia

NEW JACAMAR OIL FIELD DISCOVERY
EXTENSION OF JACANA OIL FIELD BOUNDARIES
NEW ZONE ADDITION IN JACANA OIL FIELD
ADDITIONAL PRODUCTION IN TIGANA OIL FIELD

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 Peru, today announced new drilling and testing successes in the Llanos 34 Block (GeoPark operated with a 45% working interest) in Colombia.

New Jacamar Oil Field Discovery

Exploring a fault trend southeast of the Tigana/Jacana oil field complex, GeoPark drilled and completed the Jacamar 1 exploration well to a total depth of 10,627 feet. A test conducted with an electric submersible pump in the Guadalupe formation resulted in a production rate of approximately 1,000 bopd of 17.5 degrees API, with 13% water cut, through a choke of 38/64 mm and wellhead pressure of 79 pounds per square inch. Additional production history is required to determine stabilized flow rates of the well. Surface facilities are in place and the well is already in production. Oil shows during drilling and petrophysical analysis indicate the potential for hydrocarbon production also in the shallower Mirador and the deeper Gacheta formations.

Jacana Oil Field Extension

Following the drilling of the Jacana Sur 2 appraisal well in the first quarter of 2017 to test the northwest boundaries of the Jacana oil field, a test was conducted with an electric submersible pump in the Guadalupe formation. It resulted in a production rate of approximately 270 bopd of 16.5 degrees API, with 21% water cut, through a choke of 32/64 mm and wellhead pressure of 48 pounds per square inch. Additional production history is required to determine stabilized flow rates of the well. Surface facilities are in place and the well is already in production.
