Breakdown of Quarterly Production by Country

The following table shows production figures for 4Q2023, as compared to 4Q2022:

Quarterly Production

Oil and Gas Production Update

Consolidated:

Average net oil and gas production in 4Q2023 was 38,315 boepd, flat compared to 4Q2022, due to higher production in Colombia and Ecuador that was offset by lower production in Chile and Brazil. Oil represented 93% and 92% of total reported production in 4Q2023 and 4Q2022, respectively.

Compared to 3Q2023, consolidated oil and gas production increased 10%, due to recent exploration successes in Colombia and Ecuador and the resumption of shut-in production in the CPO-5 Block.

Colombia:

Average net oil and gas production in Colombia increased by 1% to 34,154 boepd in 4Q2023 compared to 33,749 boepd in 4Q2022, mainly due to higher production in the CPO-5 Block and to a lesser extent new production in the Llanos 123 Block, partially offset by lower production in the Platanillo Block (GeoPark operated, 100% WI) and the Llanos 34 Block.

Oil and gas production in GeoPark’s main blocks in Colombia in 4Q2023 was as follows:

• Llanos 34 Block net average production decreased by 2% to 24,147 bopd (or 53,660 bopd gross) in 4Q2023 compared to 4Q2022, mainly due to the natural decline of the fields, partially offset by development drilling activities including the successful horizontal well drilling campaign
• CPO-5 Block net average production increased by 12% to 6,820 bopd (or 22,734 bopd gross) in 4Q2023 compared to 4Q2022, mainly due to the reopening of the Indico 6 and Indico 7 wells in late September 2023
• Platanillo Block average production decreased by 28% to 1,658 bopd in 4Q2023 compared to 4Q2022, due to the natural decline of the fields and to a lesser extent a damaged injector well
• Llanos 123 Block net average production was 1,083 bopd (or 2,166 bopd gross) in 4Q2023, reflecting production from the Saltador 1 exploration well and partial production from the Toritos 1 and Bisbita Centro 1 exploration wells that were put on production during 4Q2023

Recent Activity in the Llanos Basin

Llanos 34 Block

• Two horizontal wells were drilled and put on production during 4Q2023 and a total of five horizontal wells were put on production in full-year 2023 and are currently producing approximately 10,060 bopd gross¹¹ in aggregate
• GeoPark plans to drill 2-3 additional horizontal wells in 1Q2024

CPO-5 Block

• The Halcon 1 exploration well reached total depth in late October 2023 with preliminary logging information indicating hydrocarbon potential in the Paleocene (Guadalupe) formation. Initial production tests showed intermittent flow rates. A build-up test indicated potential well damage which could be affecting well productivity. A workover is planned to repair damage and resume testing activities in late January 2024
• The Perico 1 exploration well reached total depth in December 2023 with preliminary logging information indicating hydrocarbon potential in the Barco (Guadalupe) formation. Testing activities started on January 10^th, 2024 and the well is currently producing 650 bopd of 14 degrees API with a water cut of 8%
• Preliminary activities are currently ongoing to acquire 230 square kilometers of 3D seismic in the northeastern part of the block which is expected to add more prospects to GeoPark’s organic exploration inventory

Llanos 123 Block

• The Bisbita Centro 1 exploration well reached total depth in November 2023 with logging information indicating hydrocarbon potential in the Paleocene (Guadalupe) formation. Testing activities started in late November 2023 and the well is currently producing approximately 750 bopd of 19 degrees API with a water cut of less than 1%
• The Bisbita Centro 1 well is the third successful exploration well drilled by GeoPark in the Llanos 123 Block in 2023, following the Saltador 1 and the Toritos 1 exploration wells that initiated testing in July and October 2023, respectively

Llanos 87 Block

• The Zorzal Este 1 exploration well reached total depth in November 2023 with logging information indicating hydrocarbon potential in the Paleocene (Guadalupe) formation. Testing activities started in late November 2023 and the well is currently producing approximately 575 bopd of 33 degrees API with a water cut of 1%

Llanos 86 and Llanos 104 blocks (GeoPark operated, 50% WI):

• The Llanos 86 and Llanos 104 blocks are adjacent to the eastern side of the CPO-5 Block
• Initial activities have been carried out to acquire over 650 square kilometers of 3D seismic
• Once executed, this project would be one of the three biggest onshore seismic acquisition projects in Colombia and is expected to add further prospects to GeoPark’s organic exploration inventory

Ecuador:

Average net oil production in Ecuador before the Government’s share increased 13% to 1,419 bopd in 4Q2023, (approximately 969 bopd after the Government’s share), compared to 1,259 bopd in 4Q2022, mainly due to the successful drilling and testing of the Yin 2, Perico Centro 1 and Perico Norte 4 wells in the new combined structural/stratigraphic U-sand play in the Perico Block.

Ecuador is currently producing approximately 2,820 bopd gross.

The Government’s production share varies with oil prices and is approximately 30-40%, considering an Oriente crude oil price of $70-100 per barrel.

Chile:

Average net production in Chile decreased 28% to 1,641 boepd in 4Q2023 compared to 2,291 boepd in 4Q2022, resulting from the natural decline of the fields and limited drilling activities.

The production mix was 79% natural gas and 21% light oil in both 4Q2023 and 4Q2022.

Brazil:

Average net production in the Manati field (GeoPark non-operated, 10% WI) in Brazil decreased 3% to 1,101 boepd in 4Q2023 compared to 1,134 boepd in 4Q2022.

The production mix was 99% natural gas and 1% oil and condensate in both 4Q2023 and 4Q2022.

Divesting Non-Core Operations in Chile

In December 2023, GeoPark signed an agreement with Servicom Chile SPA to divest its non-core and low-netback operations in Chile for $4 million (subject to certain working capital adjustments at the closing date), including its working interest in the Fell, Isla Norte, Flamenco and Campanario blocks. Closing of the transaction is expected to occur in 1Q2024.

In 2023, GeoPark’s operations in Chile produced 1,720 boepd (87% natural gas). Adjusted EBITDA from operations in Chile for the first nine months of 2023 totaled $3.6 million.

GeoPark’s 2024 consolidated average production guidance of 37,000-40,000 boepd does not consider the Chile divestment and currently includes Chile’s 2024 average production, which was estimated at 1,000-1,300 boepd. The Company will update its production guidance after the closing of the transaction, although it expects its Adjusted EBITDA and Free Cash Flow guidance released on November 8, 2023 to remain unchanged by this divestment.
