Breakdown of Quarterly Production by Country

The following table shows production figures for 3Q2022, as compared to 3Q2021:

Quarterly Production

Oil and Gas Production Update

Consolidated:

Oil and gas production in 3Q2022 was 38,396 boepd. Adjusting for divestments in Argentina (completed on January 31, 2022), consolidated oil and gas production increased by 8% compared to 3Q2021, due to higher production in Colombia, Chile and Ecuador, partially offset by lower production in Brazil. Oil represented 91% and 87% of total reported production in 3Q2022 and 3Q2021, respectively.

Compared to 2Q2022, oil and gas production was 1% lower, mainly due to temporary local blockades in Colombia that reduced 3Q2022 production by approximately 1,100-1,200 boepd, and to a lesser extent, lower gas production in Brazil.

Colombia:

Average net oil and gas production in Colombia increased by 6% to 33,338 boepd in 3Q2022 compared to 31,565 boepd in 3Q2021, resulting from increased production in the Llanos 34 and CPO-5 blocks, partially offset by lower production in the Platanillo block.

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

• Llanos 34 block net average production increased by 3% to 25,968 bopd (or 57,707 bopd gross) in 3Q2022 compared to 3Q2021
• CPO-5 block net average production increased by 48% to 5,600 bopd (or 18,667 bopd gross) in 3Q2022 compared to 3Q2021. Production and operations in the CPO-5 block were affected by blockades for 10 days in 3Q2022
• Platanillo block average production decreased by 31% to 1,505 bopd in 3Q2022 compared to 3Q2021. Production and operations in the Platanillo block were affected by blockades for 38 days in 3Q2022 (approximately 600 bopd of lower production in 3Q2022). The Platanillo block is currently producing 2,500 bopd (including production from the Alea NW 1 well)

Ongoing Activity in the Llanos Basin

Llanos 34 Block

• Added a third drilling rig that started spudding wells in August 2022
• Interconnection of the block to Colombia’s national power grid (~70% hydroelectric⁷) has been fully operational since mid-July 2022
• Solar photovoltaic plant to be fully operational during 4Q2022
• 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’s 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

• Indico 6 development well was spudded on September 9, 2022, to a total depth of 10,446 feet
  • Preliminary logging information indicated 201 feet of net pay in the Ubaque formation
  • Initial production tests showed a production rate of 3,800 bopd of 35 degrees API with a 0.15% water cut (on a restricted 32/64 inch choke)
  • Currently executing pressure build-up tests, expecting to resume production within the next few days
• Cante Flamenco 1 exploration well was spudded on June 19, 2022, to a total depth of 11,807 feet
  • Preliminary logging information indicated 40 feet of net pay in the Mirador formation
  • Initial production tests showed a production rate of 170 bopd of 15 degrees API with 90% water cut
  • Well intervention activities are planned in 4Q2022 targeting an increase in production rates
• Apterix 1 exploration well, testing an exploration prospect in the southern part of the block, was spudded on August 18, 2022, to a total depth of 8,834 feet
  • According to petrophysical logging interpretation, the well encountered reservoir in the Guadalupe formation, with no evidence of hydrocarbons, and the well was abandoned
  • The joint venture partners decided to suspend drilling of further wells in the southern part of the block to recalibrate maps and conduct further evaluations with new information obtained from Apterix 1 well

Llanos 87 Block

• Currently drilling the Tororoi 1 exploration well, total depth expected in November 2022
• Civil works currently underway targeting drilling of 1-2 additional exploration prospects in 4Q2022

Llanos 94 Block

• Currently drilling the Humea 1 exploration well, total depth expected in November 2022

Chile:

Average net production in Chile increased by 3% to 2,425 boepd in 3Q2022 compared to 2,354 boepd in 3Q2021, resulting from higher oil production, partially offset by lower gas production due to the natural decline of the fields and limited drilling activities. The production mix was 84% natural gas (vs 88% in 3Q2021) and 16% light oil (vs 12% in 3Q2021).

Brazil:

Average net production in the Manati field in Brazil decreased by 20% to 1,439 boepd in 3Q2022 compared to 1,791 boepd in 3Q2021. Production in Manati was temporarily interrupted for 7 days in September 2022 due to lower gas demand. Production has been gradually recovering since end-September, with current net production of approximately 1,500 boepd.

The production mix was 99% natural gas and 1% oil and condensate in both 3Q2022 and 3Q2021.

Ecuador:

Perico block (GeoPark non-operated, 50% WI)

Average net oil production in Ecuador reached 1,194 bopd in 3Q2022 before the Government’s production share (or 711 bopd after the Government’s share), with production in the quarter being affected by well intervention activities and facilities optimization works carried out in the Yin 1 well.

The Perico block is currently producing approximately 3,000 bopd gross, or 1,500 bopd net from the Jandaya, Tui and Yin fields, before considering the Government’s production share.

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.

Espejo block

Drilled the Pashuri 1 exploration well that reached total depth in October 2022. Preliminary logging information and other relevant data indicated the presence of hydrocarbons in the M1 and U sandstones in the Napo formation. Completion activities currently underway with production tests to initiate by end-October 2022.
