FOR IMMEDIATE DISTRIBUTION

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

Santiago, Chile – June 12, 2017 - 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.

Jacana Oil Field New Formation Addition

Following the drilling of the Jacana 8 appraisal well in the first quarter of 2017 to test a channel sand in the Mirador formation, which had not previously produced oil in the Jacana oil field, a test conducted with an electric submersible pump resulted in a production rate of approximately 1,850 bopd of 24.0 degrees API, with 0.4% water cut, through a choke of 32/64 mm and wellhead pressure of 100 pounds per square inch. The deeper Guadalupe formation was also tested and oil was found in an area which previously had no reserves assigned to it. 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.

Tigana Oil Field Production Addition

GeoPark drilled and completed the Tigana Sur 5 development well to a total depth of 11,310 feet. A test conducted with an electric submersible pump in the Guadalupe formation resulted in a production rate of approximately 1,010 bopd of 14.9 degrees API, with a 0.4% water cut, through a choke of 32/64 mm and wellhead pressure of 85 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.

Current Drilling

Current drilling by GeoPark includes:

Colombia: Jacana 9 appraisal well to test the northern limits of the Jacana oil field and Curucucu 1 exploration well to test a new prospect adjacent to the newly-discovered Jacamar oil field – both wells in the Llanos 34 Block (GeoPark operated with a 45% WI) in the Llanos Basin

Argentina: Rio Grande Oeste 1 exploration well in the CN-V Block (GeoPark operated with a 50% WI) in the Neuquen Basin

Chile: Kimiri Aike 4 development well in the Fell Block (GeoPark operated with a 100% WI) in the Magallanes Basin

GeoPark’s total oil and gas production is continuing to grow with new drilling results and is currently over 27,900 boepd.

Oil Market Hedge Position

For the period July 2017 to December 2017, GeoPark secured a minimum Brent price of $51 per barrel for 6,000 bopd through a zero-cost collar structure that includes a maximum price of $57.5 per barrel. Approximately 50-60% of GeoPark’s production is hedged through the third quarter of 2017 at a floor of $51-$53 per barrel and 25-30% is hedged through the fourth quarter of 2017 at a floor of $51.

James F. Park, CEO of GeoPark, commented: “Congratulations to our team for being able to execute and deliver such impressive results across our assets in such a compressed period. We continue to find more oil and grow production in the Llanos 34 Block as we work to extend limits, add new formations and explore new accumulations. We are now exploring and developing familiar and reliable rocks in Argentina and Chile. GeoPark has always grown by the drill bit and continues to demonstrate an exceptional drilling success rate with world-beating finding and development costs.”
