Breakdown of Quarterly Production by Country

The following table shows production figures for 2Q2022, as compared to 2Q2021:

Quarterly Production

Oil and Gas Production Update

Consolidated:

Oil and gas production in 2Q2022 was 38,940 boepd. Adjusting for recent divestments in Argentina, consolidated oil and gas production increased by 14% compared to 2Q2021, due to higher production in Colombia and recent exploration successes in Ecuador, partially offset by lower production in Chile and Brazil.

Oil represented 90% and 85% of total reported production in 2Q2022 and 2Q2021, respectively.

Colombia:

Average net oil and gas production in Colombia increased by 16% to 34,253 boepd in 2Q2022 compared to 29,571 boepd in 2Q2021, resulting from increased production in the Llanos 34, CPO-5 and Platanillo blocks.

Production growth resulted from successful development drilling activities. Production in Colombia in 2Q2021 was partially impacted by protests and demonstrations against the Government that affected overall logistics, causing the Company to manage production curtailments in May and June 2021.

Oil and gas production highlights in GeoPark’s main blocks in Colombia:

• Llanos 34 block net average production in 2Q2022 increased by 5% to 25,635 bopd (or 56,967 bopd gross), compared to 24,515 bopd (or 54,478 bopd gross) in 2Q2021
• CPO-5 block net average production in 2Q2022 increased by 77% to 6,090 bopd (or 20,300 bopd gross), compared to 2Q2021, or 150% up compared to production prior to GeoPark’s acquisition in January 2020
• Platanillo block average production in 2Q2022 increased by 97% to 2,190 bopd, compared to 1,110 bopd in 2Q2021. Production and operations in the Platanillo block were affected for 15 days in May 2022 due to local community blockades against the Government (protests were not directed at GeoPark specifically or even the oil industry in general)

Ongoing Activity in the Llanos Basin

Llanos 34 Block

• Adding a third drilling rig, expecting to spud wells in early August 2022
• Interconnection of the block to Colombia’s national power grid (~70% hydroelectric⁹) has been fully operational since mid-July 2022
• Solar photovoltaic plant to be fully operational by early August 2022
• The interconnection of the block and the development of renewable energy projects such as the solar photovoltaic plant are key drivers to continue improving the Llanos 34 block industry-leading cost and carbon footprint performance, allowing GeoPark to replace a significant portion of the Company’s gas and diesel consumption with renewable energy

CPO-5 Block

• Initiated drilling of the Cante Flamenco 1 exploration well, located 4 km west of the Urraca 1 well, looking for hydrocarbon potential in the Ubaque and Mirador formations, with Guadalupe as a secondary target
• 2H2022 work program targets drilling of 1-2 development wells to further accelerate production growth in the Indico field, to be followed by 3-5 high-potential exploration wells (1-2 wells next to Llanos 34 to test the extension of the Jacana field and 2-3 wells in the southeastern part of the block)

Llanos 87 Block

• Obtained environmental license, allowing exploration and delineation drilling plus related infrastructure
• Civil works and other pre-drilling activities underway, targeting to spud the Tororoi exploration prospect in 3Q2022, to be followed by 1-2 exploration wells in 4Q2022

Chile:

Average net production in Chile decreased by 9% to 2,358 boepd in 2Q2022 compared to 2,584 boepd in 2Q2021, resulting from lower gas production due to limited drilling activities combined with the field’s natural decline, partially offset by increased oil production resulting from successful well intervention activities. The production mix was 78% natural gas (vs 89% in 2Q2021) and 22% light oil (vs 11% in 2Q2021).

Brazil:

Average net production in Brazil decreased by 19% to 1,695 boepd in 2Q2022 compared to 2,080 boepd in 2Q2021. The production mix was 99% natural gas and 1% oil and condensate in both 2Q2022 and 2Q2021.

Ecuador:

The Perico block is currently producing over approximately 3,000 bopd gross, or 1,500 bopd net from the recent Jandaya, Tui and Yin discoveries, before considering the Government’s production share. Net production after the Government’s production share currently equals approximately 900 bopd. The Government’s production share varies with oil prices and is approximately 30-40% considering an Oriente crude oil price of $70-100 per bbl.

In 2Q2022 average net oil production in Ecuador reached 634 bopd before the Government’s production share and 363 bopd after the Government’s share, with the quarter only partially reflecting production from the recent Yin 1 well that started testing activities in late June 2022.

Perico block

During 2Q2022 the operator put on production the Yin 1 exploration well:

• On May 15, 2022, the operator spudded the Yin 1 exploration well, located to the southwest of the Jandaya oil field that was discovered in January
• The well was drilled and completed to a total depth of 11,345 feet. Preliminary logging information indicated hydrocarbons in the Hollin formation
• The Yin 1 well is currently showing a production rate of 2,000 bopd gross of 27 degrees API with a 1% water cut
• The complete testing program is underway and additional production history will be required to determine stabilized flow rates of the well and the extent of the reservoir
• GeoPark and its partner are evaluating subsequent activities, including a potential development drilling plan for recent discoveries in Jandaya, Tui and Yin fields

Espejo block

In the Espejo block, GeoPark completed the acquisition of 60 sq km of 3D seismic. The Company recently obtained environmental license approval and civil works are currently underway, targeting to spud the Pashuri 1 exploration well in September 2022.
