Oil and Gas Production Update

Consolidated:

Annual average 2020 production of 40,192 boepd compared to 40,046 boepd in 2019. Oil and gas production in 4Q2020 decreased by 6% to 39,304 boepd from 41,786 boepd in 4Q2019, due to limited drilling and maintenance activities in Colombia, Chile and Argentina and lower gas demand in Brazil, partially offset by the addition of production from the Amerisur acquisition in Colombia. Oil represented 85% of total reported production in 4Q2020 and 4Q2019.

Colombia:

Average net oil and gas production in Colombia decreased by 4% to 31,858 boepd in 4Q2020 compared to 33,311 boepd in 4Q2019, reflecting limited drilling and maintenance activities in the Llanos 34 block (GeoPark operated, 45% WI), partially offset by the recent acquisition of Amerisur and successful drilling of the Indico 2 appraisal well in the CPO-5 block.

The Llanos 34 block average net production was 25,759 bopd (or 57,242 bopd gross) in 4Q2020, representing 81% of GeoPark's net production in Colombia, while the CPO-5 block average net production was 3,093 bopd (or 10,310 bopd gross), representing 10% of GeoPark's net production in Colombia and a 55% increase compared to 3Q2020.

Appraisal and exploration drilling in the CPO-5 block:

• Indico 2 appraisal well, located approximately 0.8 km northwest of the Indico 1 well, was successfully drilled and put on production in November 2020. The operator ONGC Videsh drilled and completed Indico 2 to a total depth of 10,925 feet. The well tested 5,500 bopd of 35 degrees API, with a 0.1% water cut, and is currently producing 6,200 bopd. Additional production history is required to determine stabilized flow rates of the well.
• Aguila 1 exploration well was drilled by the operator ONGC Videsh to a total depth of 9,961 feet. According to petrophysical logging interpretation and other relevant information, the well encountered non- commercial oil accumulations, and following these results a decision was made to abandon the well.
• Further exploration, appraisal and development activities are budgeted in the CPO-5 block in 2021 with the drilling of 5-6 gross wells plus the acquisition of 3D seismic, as part of GeoPark's fully funded and flexible work and investment program.
• CPO-5is a large high-potential block offering multi-play, low cost development, appraisal and exploration opportunities, adjacent to and on trend with the Llanos 34 block, and with over 20 drilling leads and prospects delineated to date.

Other activities in operated and non-operated blocks:

• Initiated 3D seismic acquisition in the PUT-8 block (GeoPark operated, 50% WI) which is located adjacent to the Platanillo Block (GeoPark operated, 100% WI) in the Putumayo basin, expected to continue in 1Q2021.
• Re-entryactivities carried out into the Grulla 1 well in the Llanos 94 block (GeoPark non-operated, 50% WI) showed non-commercial oil accumulations, and following these results a decision was made to abandon the well.

Chile:

Average net production in Chile decreased by 5% to 3,133 boepd in 4Q2020 resulting from lower gas production in the Jauke gas field, partially offset by the discovery of the Jauke Oeste gas field in early 2020. Maintenance and well intervention activities will be carried out in the Jauke 1 gas well during 1Q2021, aimed at increasing gas production levels. The production mix during 4Q2020 was 89% gas and 11% light oil (compared to 81% gas and 19% light oil in 4Q2019).

Brazil:

Average net production in Brazil decreased by 23% to 2,167 boepd in 4Q2020 compared to 2,799 boepd in 4Q2019. Compared to 3Q2020, Brazilian production increased by 37% due to higher demand in the Manati gas field (GeoPark non-operated, 10% WI). The production mix during 4Q2020 was 99% natural gas and 1% condensate (compared to 96% natural gas and 4% oil and condensate in 4Q2019).

Agreement to sell 10% WI in the Manati gas field:

• On November 23, 2020, GeoPark announced that its Board of Directors approved an agreement to sell its 10% non-operated WI in the Manati gas field to Gas Bridge for a total consideration of R$144.4 million (approximately $27 million), including a fixed payment of R$124.4 million plus an earn-out of R$20.0 million, which is subject to obtaining certain regulatory approvals.
• The transaction was agreed with an effective date of December 31, 2020 and is subject to certain conditions, including the acquisition by Gas Bridge of the remaining 90% WI and operatorship of the Manati gas field.
• Two other non-operating partners in the Manati gas field consortium with a combined 55% WI have announced their respective agreements to sell their WI to Gas Bridge.
• Closing of the transaction would occur in 4Q2021, subject to the agreement by the remainder of the consortium and required regulatory approvals.

Argentina:

Average net production in Argentina decreased by 10% to 2,146 boepd in 4Q2020 (57% oil, 43% gas) compared to 2,384 boepd in 4Q2019 (66% oil, 34% gas), mainly resulting from limited maintenance activities combined with the natural decline of the fields.
