1. Colombian production includes approximately 640 bopd, 765 bopd and 888 bopd during 2Q2019, 1Q2019 and 4Q2018, respectively, 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 8% to 41,786 boepd in 4Q2019 from 38,741 boepd in 4Q2018, due to increased production in Colombia and Chile, partially offset by lower production in Brazil. Oil represented 85% of total reported production compared to 84% in 4Q2018.

On July 1, 2019, GeoPark completed the divestiture of the La Cuerva and Yamu blocks in Colombia. Adjusting for the sale of these blocks (888 bopd in 4Q2018), the Company's consolidated oil and gas production increased by 10% in 4Q2019 and Colombian production increased by 12%.

Colombia:

Average net oil and gas production in Colombia grew 9% to 33,311 boepd in 4Q2019 compared to 30,641 boepd in 4Q2018, 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 in Colombia during 4Q2019 were:

Exploration/Delineation drilling in the Llanos 34 block:

• The Tigui 18 appraisal well was successfully drilled and tested during 4Q2019 to evaluate a southeast area of the field, outside the 2018 D&M certified 3P reserve area, and thus extending the field's size. Oil shows during drilling and petrophysical analysis indicated the potential for hydrocarbons in the Guadalupe and Gacheta formations. The well was drilled to a total depth of 11,514 feet. A production test conducted with an electric submersible pump in the Guadalupe formation resulted in a production rate of approximately 1,500 bopd, 15.6 degrees API with a 4% water cut.
• The Tigui 12 appraisal well was drilled during 4Q2019 to continue delineating the northeastern part of the field. Oil shows during drilling and petrophysical analysis indicated the potential for hydrocarbons in the Guadalupe and Gacheta formations. Testing activities are currently underway.

Development drilling in the Llanos 34 block:

• Five new wells were tested and put on production in the Llanos 34 block, currently adding above 7,500 bopd gross, including wells Tigana Norte 13, Tigana Norte 18, Tigui 21, Jacana 32 and Jacana 35.

Exploration drilling in the Llanos 32 block:

• The Azogue 1 exploration well was drilled to a total depth of 12,125 feet. Logging results indicated the potential for hydrocarbons in the Une, Guadalupe and Mirador formations. A production test conducted with an electric submersible pump in the Guadalupe formation resulted in a production rate of approximately 1,500 bopd, 28 degrees API and a 1% water cut. The well is currently producing 2,250 bopd.
• The Azogue oil field is located to the southern part of the Llanos 32 block, adjacent to and approximately 1,200 meters from the Chiricoca oil field in the Llanos 34 block.

Amerisur acquisition:

• On November 15, 2019, GeoPark announced that it will acquire the entire issued and to be issued share capital of Amerisur with closing expected in January 2020, subject to customary regulatory approvals.
• The acquisition of Amerisur is in line with GeoPark's strategy, providing growth in reserves, production and cash flow and enriching GeoPark's inventory of short, medium and long-term exploration opportunities.
• GeoPark will incorporate 13 production, development and exploration blocks in Colombia, including 12 operated blocks in the Putumayo basin and the CPO-5non-operated block in the Llanos basin, a successful operating team, and the Oleoducto Binacional Amerisur, an export oil pipeline from Colombia to Ecuador.
• GeoPark expects to generate significant synergies in operations, transport and crude oil blending in the Llanos 34 block and in the Putumayo blocks.
• The transaction brings the opportunity to enhance valuable partnerships with Oxy, partner in five of the Putumayo blocks and with ONGC, operator of the CPO-5 block and with which GeoPark has a long- term strategic alliance to acquire a portfolio of projects across Latin America.
• Key metrics of Amerisur include net light oil production of 6,865 bopd (September 2019), net proven reserves and net proven and probable reserves of 15.0 million and 21.8 million barrels, respectively (certified by McDaniel & Associates as of end July 2019) and net unrisked exploration resources of 289 million to 566 million barrels (mean to high-end, estimated by McDaniel & Associates).
• Amerisur is a cashflow positive, growing business with low operating costs. Amerisur's balance sheet is strong, with no financial debt and a cash position of $46 million as of June 30, 2019
• For further details, please refer to the release published on November 15, 2019.

Strategic exploration acreage expansion in Colombia:

• As part of the recent ANH's Permanent Process for the Assignment of Areas, GeoPark was awarded the Llanos 123 and Llanos 124 blocks in partnership with Hocol (a 100% subsidiary of Ecopetrol) and Amerisur was awarded the PUT-36 block.
• GeoPark and Parex Resources executed an agreement in which GeoPark will assume, subject to ANH approval, a 50% WI in the Llanos 94 block in exchange for funding its 50% pro-rata share of existing commitments, with no carry.
• With the addition of these new blocks during 2019 and upon the closure of the recently announced acquisition of Amerisur, GeoPark will significantly expand its acreage position around its core Llanos 34 block by adding approximately 1.4 million gross acres - 17 times the size of the Llanos 34 block.
• For further details, please refer to the release published on December 17, 2019.

Brazil:

Average net production in Brazil decreased slightly by 3% to 2,799 boepd in 4Q2019 compared to 2,894 boepd in 4Q2018 (96% gas in 4Q2019 and 98% gas in 4Q2018). However, compared to 3Q2019, Brazilian production increased by 22% mainly due to higher demand in the Manati gas field, and to a lesser extent, due to long- term testing activities in the Praia dos Castelhanos oil field in the REC-T-128 block (GeoPark operated, 70% WI).

Exploration drilling in the Reconcavo and Potiguar basins:

• Praia dos Castelhanos 1 well in the REC-T-128 block initiated long-term testing activities in late 3Q2019, averaging 157 bopd gross of light oil during 4Q2019.
• Mandacaru exploration prospect in the POT-T-747 block (GeoPark operated, 70% WI) was drilled to a total depth of 670 meters. Petrophysical logging interpretation indicated non-commercial oil accumulations, and following these results, a decision was made to plug and abandon the well.

Chile:

Average net production in Chile increased by 17% to 3,292 boepd. Higher production in 4Q2019 resulted from the successful development of the Jauke gas field. The production mix during 4Q2019 was 81% gas and 19% light oil (compared to 74% gas and 26% light oil in 4Q2018).

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

• Jauke Oeste 1 exploration well was drilled to a total depth of 9,596 feet. Preliminary logging

information indicated potential for hydrocarbons in the Tobifera formation. Testing activities are currently underway.

Exploration drilling in the Isla Norte block (GeoPark operated, 50% WI):

• Civil works and other preliminary activities were carried out during 4Q2019 in the Leun exploration prospect in the Isla Norte block, expected to spud in 1Q2020.

Argentina:

Average net production in Argentina remained flat, reaching 2,384 boepd in 4Q2019 (66% oil, 34% gas) compared to 2,383 boepd in 4Q2018 (65% oil, 35% gas). Stable production levels during 2019 resulted from a successful and ongoing optimization project initiated in 2018 focused on enhancing base production levels.
