REVISED 2021 GUIDANCE

As announced on May 17, June 1 and July 1, extensive protests and demonstrations across Colombia affected overall logistics and supply chains, restricting GeoPark’s crude oil transportation, drilling and the mobilization of personnel, equipment, and supplies. These events caused the Company and its joint venture partners to manage production curtailments and to temporarily suspend or delay drilling and maintenance activities.

Operations normalized by the end of 2Q2021 and GeoPark is currently producing 38,000-39,000 boepd, with 2H2021 production expected to average 39,000-42,000 boepd.

Revised 2021 production guidance of 38,000-40,000 average boepd (from previous 41,000-43,000 boepd) results from production curtailments during 2Q2021 related to extensive protests in Colombia (which account for approximately 800-1,000 boepd of the revised estimate), delays in the execution of certain maintenance and capital expenditure projects (mainly in the Platanillo and CPO-5 blocks) and to a lesser extent, due to a combination of field and well performance, including higher downtime due to floods temporarily affecting surface facilities and electrical system failures in the Llanos 34 block.

Delayed maintenance and drilling activities in the Platanillo block were mainly caused by the blockades in Colombia. In the CPO-5 block, the operator has delayed the spud of the Indico 4 development well to 4Q2021 (originally scheduled for June 2021), targeting drilling of 2-3 wells during 2021 (from previous 5-6 wells, with the remaining 2-3 wells expected to be spudded in 1Q2022).

Capital expenditures have been revised down to $125-140 million (from $130-150 million), which will compensate a significant portion of the lower operating netbacks that results from lower production and thus reducing its impact on free cash flow.

The table below provides further details about GeoPark’s revised 2021 guidance compared to its previous guidance.

Breakdown of Quarterly Production by Country

The following table shows production figures for 2Q2021, as compared to 2Q2020:

Quarterly Production Evolution

Oil and Gas Production Update

Consolidated:

Oil and gas production in 2Q2021 decreased by 1% to 36,489 boepd from 36,912 boepd in 2Q2020, mainly resulting from lower oil and gas production in Colombia and Chile, partially offset by increased production in Brazil and Argentina.

Oil represented 85% and 88% of total reported production in 2Q2021 and 2Q2020, respectively.

Colombia:

Average net oil and gas production in Colombia decreased by 5% to 29,571 boepd in 2Q2021 compared to 31,072 boepd in 2Q2020.

GeoPark’s 2Q2021 production in Colombia was affected by extensive protests and demonstrations that affected overall logistics, restricting the Company’s crude oil transportation, drilling and the mobilization of personnel, equipment, and supplies, causing the Company to manage production curtailments that started in early May and normalized towards the end of June.

Oil and gas production in main blocks in Colombia was as follows:

• Llanos 34 block net average production was 24,515 bopd in 2Q2021 and current production is approximately 25,000 bopd (or 56,000 bopd gross)
• CPO-5 block net average production was 3,445 bopd (or 11,483 bopd gross) in 2Q2021 and current production is approximately 3,900 bopd (or 13,000 bopd gross)
• Platanillo block average production was 1,110 bopd in 2Q2021 and current production is approximately 2,000 bopd

Latest developments in the Llanos 34 block:

• Three active drilling rigs expecting to spud 14-16 gross wells during 2H2021 (mainly targeting development projects in Tigana, Jacana and Tigui oil fields)
• Environmental impact studies and other preliminary works underway to connect the block to the national power grid, expected to be operational by the end of 2022
• Initiated engineering works for the PV solar project, expected to be operational by June 2022
• Grid connection and PV solar projects are key drivers to continue improving the Llanos 34 block’s industry-leading cost and carbon footprint performance

Latest developments in the CPO-5 block:

• Completed 250 sq km of 3D seismic acquisition in 2Q2021, expected to add additional leads and prospects in the central area of the block

Other activities in operated and non-operated blocks:

• Llanos 94 block (GeoPark non-operated, 50% WI): pre-drilling activities underway in the Humea exploration prospect, spudding expected in 3Q2021
• PUT-8 block (GeoPark operated, 50% WI): Completed 112 sq km of 3D seismic acquisition in 2Q2021. PUT-8 is adjacent to the Platanillo block in the Putumayo basin

Chile:

Average net production in Chile decreased by 17% to 2,584 boepd in 2Q2021 compared to 3,101 boepd in 2Q2020, resulting from lower gas production in the Jauke and Jauke Oeste gas fields. Maintenance and well intervention activities were carried out in Jauke Oeste, affecting gas production in 2Q2021. The production mix during 2Q2021 was 89% gas and 11% light oil (compared to 92% gas and 8% light oil in 2Q2020).

Brazil:

Average net production in Brazil increased by 206% to 2,080 boepd in 2Q2021 compared to 679 boepd in 2Q2020 due to higher gas demand in northern Brazil. The production mix during 2Q2021 was 99% natural gas and 1% oil and condensate (compared to 88% natural gas and 12% oil and condensate in 2Q2020).

Argentina:

Average net production in Argentina increased by 9% to 2,254 boepd in 2Q2021 compared to 2,060 boepd in 2Q2020. The production mix during 2Q2021 was 58% oil and 42% natural gas (compared to 61% oil and 39% natural gas in 2Q2020).
