GeoPark Announces New Oil Field Discovery in Argentina

BUENOS AIRES, Argentina–(BUSINESS WIRE)–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, and Wintershall Energía S.A.
(“Wintershall”), a subsidiary of the BASF group, the fourth largest gas
producer in Argentina with over 15 blocks, today announced the discovery
of a new oil field in the CN-V block (GeoPark 50% WI, Wintershall 50%
WI) in the Neuquen Basin, Mendoza Province of Argentina.

The Rio Grande Oeste 1 exploration well – operated by GeoPark – was
drilled and completed to a total depth of 5,500 feet targeting the Grupo
Neuquen formation, where fifteen different potential reservoir sands
were identified – at depths that range from 1,800 to 5,500 feet – with a
potential net pay of 400 feet. Preliminary logging information indicated
hydrocarbons in the upper, middle and lower zones. The complete testing
program is still underway. To date, GeoPark has carried out production
tests in four reservoir sands, with early results showing a production
rate by natural flow of approximately 300 bopd of 28.0 degrees API, with
a 7% water cut. Additional testing and production history will be
required to determine stabilized flow rates of the well.

This discovery derisks other delineated and adjacent light oil prospects
in the CN-V block for future drilling and will provide GeoPark with a
reserve, production and cash flow base in Argentina. GeoPark and its
partner Wintershall are currently evaluating subsequent activities in
the CN-V block, including a development plan for the Rio Grande Oeste
oil field.

GeoPark acquired an interest in the CN-V block in 2015 through a
partnership with Wintershall. The block is located in the Mendoza
Province and covers an area of 117,000 acres, with 3D seismic coverage
of 180 sq km next to the producing Loma Alta Sur oil field operated by
YPF. The 3D seismic survey was acquired by Wintershall in 2015. The CN-V
block also has upside potential in the developing Vaca Muerta
unconventional play. Wintershall has the right to take over operatorship
pursuant to the terms and conditions of the farm-in agreement.

GeoPark’s total work program for 2017 in Argentina includes 7 gross
wells ($5-7 million total) expected to be drilled in 2H2017, targeting
shallow heavy oil exploration prospects in the Sierra del Nevado and
Puelen blocks (Pluspetrol operated, GeoPark with a 18% WI) in the
Neuquen Basin. The Puelen block is located north of the producing El
Corcobo oil field, operated by Pluspetrol, and Sierra del Nevado is
located east of the Llancanelo oil field, operated by YPF.

The Mendoza Province is an attractive location for GeoPark to resume its
exploration and drilling activities in Argentina. The Province produces
more than 15% of Argentina’s oil and offers suitable infrastructure to
support, refine and commercialize oil production.

James F. Park, CEO of GeoPark, said: “We are pleased to be back
operating and investing in Argentina where GeoPark’s technical team has
a long and successful history of finding oil and gas and which also
represents a highly attractive under-explored and under-developed
hydrocarbon region with multiple new project opportunities.”
