High Potential Acreage Expansion, including New Partnership with Ecopetrol/Hocol in Colombia

• Acquired three low-cost, low-risk exploration blocks in the Llanos basin in Colombia in partnership with Hocol (a 100% subsidiary of Ecopetrol) ? with GeoPark selected as Operator ? and adding 86-155 mmbbl of gross unrisked exploration resources¹
• Acquired four new attractive low-risk, low-cost blocks in Brazil, strengthening GeoPark's existing portfolio in the Reconcavo and Potiguar basins and adjacent to existing producing fields

Continued Returning Value to Shareholders

Breakdown of Quarterly Production by Country

The following table shows production figures for 3Q2019, as compared to 3Q2018:

1. Includes royalties paid in kind in Colombia for approximately 1,419 bopd in 3Q2019. No royalties were paid in kind in Brazil, Chile or Argentina.

Quarterly Production Evolution

1. Includes approximately 640 bopd from the La Cuerva and Yamu blocks that were sold on July 1, 2019.

Oil and Gas Production Update

Consolidated:

Overall oil and gas production grew by 6% to 39,619 boepd in 3Q2019 from 37,214 boepd in 3Q2018, due to increased production in Colombia, Chile and Argentina, partially offset by lower production in Brazil. Oil represented 85% of total reported production compared to 84% in 3Q2018.

On July 1, 2019, GeoPark completed the divestiture of the La Cuerva and Yamu blocks. Adjusting for the sale of these blocks (1,007 bopd in 3Q2018), the Company's consolidated oil and gas production increased by 9% in 3Q2019 and Colombian production increased by 12%.

Colombia:

Average net oil and gas production in Colombia grew 8% to 31,578 boepd in 3Q2019 compared to 29,139 boepd in 3Q2018, reflecting continued successful exploration, appraisal and development drilling in the Llanos 34 block.
Adjusting for the sale of the La Cuerva and Yamu blocks, Colombian production increased by 12%.

The main operational highlights for the Llanos 34 block in 3Q2019 were:

Exploration drilling:

• The Guaco 1 exploration well was successfully tested during September 2019. The Guaco oil field is located along the third and most western major fault trend in the Llanos 34 block. Oil shows during drilling and petrophysical analysis indicated the potential for hydrocarbons in both the Guadalupe and Mirador formations. Similar to other Llanos 34 fields, the Guaco oil field appears to be both a structural and stratigraphic trap. The well was drilled to a total depth of 11,936 feet. A production test conducted with an electric submersible pump in the Guadalupe formation resulted in a production rate of 960 bopd. Current production stabilized at a rate of 600 bopd, 24.6 degrees API with less than 1% water cut.

Development and appraisal drilling:

• Five new wells were tested and put on production, currently adding above 3,000 bopd gross, including Tigana Sur 8, Tigana Sur 14, Jacana 28, Jacana 29 and Jacana 51.

Infrastructure update:

• The flowline connecting the Llanos 34 block to the Oleoducto de los Llanos ("ODL"), one of Colombia's principal pipelines, was fully operational during 3Q2019 with oil flowing from the Jacana oil field to the ODL infrastructure, contributing to operating netback improvements and reducing overall operational risks.

Acreage Expansion in Colombia in Partnership with Ecopetrol/Hocol:

• On July 11, GeoPark signed final contracts for the Llanos 86, Llanos 87 and Llanos 104 blocks, in partnership with Hocol (a 100% subsidiary of Ecopetrol).
• The acquired blocks represent significant and attractive, low-risk, low-cost, high potential exploration acreage in the Llanos basin in proximity to GeoPark's successful Llanos 34 block, surrounded by multiple producing oil and gas fields, as well as existing infrastructure.
• GeoPark will be the operator with a 50% WI.
• The three blocks cover an aggregate area of 679,292 acres ? eight times the size of the Llanos 34 block.
• Unrisked exploration resources associated to these blocks amount to approximately 86-155 mmbbl gross in aggregate, as independently audited by Gaffney, Cline & Associates.
• For further detail, please refer to the release published on June 27, 2019.

Brazil:

Average net production in Brazil decreased by 26% to 2,292 boepd in 3Q2019 compared to 3,124 boepd in 3Q2018 (98% gas in both 3Q2019 and 3Q2018). However, compared to 2Q2019, Brazilian production increased by 35% due to higher demand in the Manati gas field.

Exploration drilling in the Reconcavo and Potiguar basins:

• Praia dos Castelhanos 1 well in the REC-T-128 block was discovered during 2Q2019, with long-term testing activities initiated in late 3Q2019 averaging 200-220 bopd gross of light oil.
• Permitting and other preliminary activities carried out during 3Q2019 related to the Mandacaru exploration prospect in the POT-T-747 block (GeoPark operated, 70% WI), expected to initiate drilling in 4Q2019.

Acreage expansion in Brazil:

• In September 2019, GeoPark was preliminarily awarded the REC-T-58, REC-T-67, REC-T-77 and POT-T-834 blocks (GeoPark operated, 100% WI) in the first cycle of the Permanent Offer held by ANP.
• Acquired blocks cover an area of 30,731 acres and represent low-risk and low-cost exploration acreage, strengthening GeoPark's existing portfolio in the Reconcavo and Potiguar basins and are adjacent to existing, producing fields. The Reconcavo blocks are located near the recent Praia dos Castelhanos discovery, in the REC-T-128 block
• Limited total commitments of approximately $1.3 million in aggregate (including bonus and work program) during the first exploration period of five years.
• For further detail, please refer to the release published on September 12, 2019.

Chile:

Average net production in Chile increased by 28% to 3,358 boepd, representing the highest level since 4Q2016. Higher production in 3Q2019 resulted from the successful discovery and development of the Jauke gas field. The production mix during 3Q2019 was 79% gas and 21% light oil (compared to 73% gas and 27% light oil in 3Q2018).

Exploration drilling in the Fell block (GeoPark operated, 100% WI):

• Civil works and other preliminary activities carried out during 3Q2019 related to the Jauke Oeste exploration prospect, expected to spud in 4Q2019.

Argentina:

Average net production in Argentina increased by 3% to 2,384 boepd in 3Q2019 (66% oil, 34% gas) compared to 2,319 boepd in 3Q2018 (65% oil, 35% gas). Higher production in 3Q2019 resulted from a successful and ongoing optimization project initiated in 2018 focused on enhancing oil production levels.

Exploration drilling in the Aguada Baguales block (GeoPark operated, 100% WI):

• The Aguada Baguales Sur 1 exploration well was drilled to a total depth of 4,839 feet. Preliminary logging information indicated potential for hydrocarbons in the Lajas and Centenario formations. Testing activities are currently underway.
