Accelerating Shareholder Returns

GeoPark Limited (“GeoPark” or the “Company”) (NYSE: GPRK), a leading independent Latin American oil and gas explorer, operator and consolidator, today announces its operational update for the three-month period ended June 30, 2023 (“2Q2023”).

All figures are expressed in US Dollars. Growth comparisons refer to the same period of the prior year, except when otherwise specified.

• 9 rigs in operation in June 2023 (5 drilling rigs and 4 workover rigs), with 3 more rigs to be added in 3Q2023 (two drilling rigs and one workover rig)

Colombia - Llanos Basin

Llanos 34 block (GeoPark operated, 45% WI):

• Average gross production of 55,307 bopd (up 1% vs 1Q2023)

  • Second horizontal well was drilled within budget and ahead of time. Also, was drilled 16% faster, 10% lower drilling costs, and with 32% longer lateral length as compared to the first horizontal well
  • The Company is evaluating drilling 3-4 additional horizontal wells in 2H2023

CPO-5 block:

• Average gross production of 17,807 bopd (up 6% vs 1Q2023), below its production potential of approximately 25,000-26,000 bopd gross, due to shut-in production of the Indico 6 and Indico 7 wells

Breakdown of Quarterly Production by Country

The following table shows production figures for 2Q2023, as compared to 2Q2022:

Quarterly Production

Oil and Gas Production Update

Consolidated:

Oil and gas production in 2Q2023 was 36,581 boepd, down by 6% compared to 2Q2022, due to lower production in Colombia, Chile and Brazil and flat production in Ecuador. Oil represented 92% and 90% of total reported production in 2Q2023 and 2Q2022, respectively.

Compared to 1Q2023, consolidated oil and gas production was flat, resulting from increased production in Colombia and Brazil that was offset by lower production in Chile and Ecuador.

Colombia:

Average net oil and gas production in Colombia decreased by 4% to 33,045 boepd in 2Q2023 compared to 34,253 boepd in 2Q2022, mainly resulting from lower production in the Llanos 34 and CPO-5 blocks, partially offset by higher production in the Platanillo block.

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

• Llanos 34 block net average production decreased by 3% to 24,888 bopd (or 55,307 bopd gross) in 2Q2023 compared to 2Q2022. Compared to 1Q2023, net average production increased by 1%
• CPO-5 block net average production decreased by 12% to 5,342 bopd (or 17,807 bopd gross) in 2Q2023 compared to 2Q2022. As previously announced on March 8, April 11 and May 3, 2023, production in 1H2023 was below its production potential of 25,000-26,000 bopd gross due to shut-in production of the Indico 6 and Indico 7 wells. Compared to 1Q2023, net average production increased by 7% (1Q2023 production and operations were affected for 9 days by localized blockades)
• Platanillo block average production increased by 12% to 2,456 bopd in 2Q2023 compared to 2Q2022. Compared to 1Q2023, net average production increased by 8%, mainly due to successful development drilling activities in 2023

Recent Activity in the Llanos and Putumayo Basins

Llanos 34 Block

• Following the successful drilling and testing of the first horizontal development well, in early June 2023 GeoPark spudded a second horizontal development well in the Tigana field
  • The well was drilled to a total depth of 14,030 feet and a horizontal lateral length of 1,680 feet
  • Total depth was reached in July 2023 and the well is expected to be completed for initial testing in late July 2023

CPO-5 Block

• The operator is currently executing required civil works and expects to resume production in the Indico 6 and Indico 7 wells in August 2023
• Pre-drilling activities are currently underway to drill the Halcon 1 exploration well in September/October 2023
  • The Halcon exploration prospect is located in the northern part of the block, close to the Llanos 34 block

Llanos 87 Block

• Targeting to drill the Zorzal 2 well, updip of the Zorzal 1 well discovery, where there is incremental potential identified in the Barco formation (subject to joint venture partner approval)

Llanos 123 Block

• In 2Q2023 GeoPark drilled its first exploration well in the block, located to the west of the Llanos 34 block and adjacent to the Llanos 124 block
• The Saltador 1 exploration well was spudded in late May and reached total depth in early July 2023
• Preliminary logging information indicated hydrocarbons in the Barco and Mirador formations
• Testing activities are expected to start in July/August 2023
• The drilling rig will initiate mobilization in the upcoming weeks to spud the Toritos 1 exploration well, expected in August 2023

Llanos 124 Block

• The Llanos 124 block is located adjacent to the west of the Llanos 34 block
• In 2Q2023 GeoPark continued executing civil works and other pre-drilling activities to spud its first exploration well in the block in early 3Q2023
• The Cucarachero 1 exploration well was spudded in July 2023 and is expected to reach total depth in August 2023

Llanos 86 and Llanos 104 Blocks

• The Llanos 86 and Llanos 104 blocks are located adjacent to the east of the CPO-5 block
• Preliminary activities currently underway to acquire over 650 square kilometers of 3D seismic, expected to be executed in early 2024
• This 3D seismic acquisition is expected to add additional exploration prospects to GeoPark’s organic exploration inventory

Put-8 Block

• Currently working on environmental licensing for the Bienparado exploration prospect

Ecuador:

Average net oil production in Ecuador before the Government’s share reached 634 bopd in 2Q2023, (approximately 448 bopd after the Government’s share), flat compared to 2Q2022.

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.

Drilling activities currently underway in the Perico block targeting to drill two wells in 3Q2023 (one development well, Yin 2, and one exploration well, Yang 1).

Chile:

Average net production in Chile decreased 28% to 1,690 boepd in 2Q2023 compared to 2,358 boepd in 2Q2022, resulting from the natural decline of the fields, limited drilling activities and temporarily shut-in oil production due to ongoing commercial negotiations with the oil offtaker. The production mix was 96% natural gas (vs 78% in 2Q2022) and 4% light oil (vs 22% in 2Q2022).

Commercial negotiations with the oil offtaker are currently ongoing and the Company expects to resume shut-in production of approximately 400 bopd in 3Q2023.

Brazil:

Average net production in the Manati field in Brazil decreased 28% to 1,212 boepd in 2Q2023 compared to 1,695 boepd in 2Q2022 due to limited gas demand, the natural decline of the field and maintenance activities affecting production in the Manati platform for 10 days during June 2023 and that were normalized by the end of June 2023.

The production mix was 98% natural gas (vs 99% in 2Q2022) and 2% oil and condensate (vs 1% in 2Q2022).
