MATA MORA NORTE POSTS RECORDS

GeoPark Limited (“GeoPark” or the “Company”) (NYSE: GPRK), a leading independent Latin American oil and gas explorer, operator and consolidator, announces its operational update for the three-month period ended September 30, 2024 (“3Q2024”).

Oil and Gas Production and Operations

• 3Q2024 consolidated average oil and gas production of 33,215[1] boepd, 7% lower than 2Q2024 due to the continued closure of the Manati gas field in Brazil (GeoPark non-operated, 10% WI), performance in the Llanos 34 Block (GeoPark operated, 45% WI) not offsetting the natural base decline, and continued blockades affecting operations in the Llanos 34 Block and the CPO-5 Block (GeoPark non-operated, 30% WI). These factors were previously identified as risks, and their realization has impacted production within the anticipated 1,500-2,500 boepd range
• Production from Llanos Exploration increased 28% vs 2Q2024 (1,581 boepd net; 3,162 boepd gross), mainly driven by the Toritos 2 and the Toritos Norte wells in the Llanos 123 Block (GeoPark operated, 50% WI)
• Production at the Mata Mora Norte Block (GeoPark non-operated, 45% WI) in Argentina reached a record of 15,418 boepd gross during August 2024. GeoPark will consolidate production from its Argentina acquisition at the closing of the transaction, expected in 4Q2024
• 9 rigs currently in operation (5 drilling rigs and 4 workover rigs), including one drilling rig in Argentina

Llanos 34 Block: Secondary Recovery Continues

• 3Q2024 average production of 20,445 boepd net (45,437 boepd gross), 11% lower than 2Q2024 and in line with the associated risks described above and in the 2Q2024 Results Release
• Horizontal wells are currently contributing 16% of total production in the block (7,400 boepd gross). First horizontal well to the Guadalupe Formation put on production on July 2024, and first short radius horizontal well to the Mirador Formation put on production on September 2024
• Waterflooding projects continued performing above plan, delivering around 5,000 boepd in 3Q2024, 11% of total production in the block
• The Curucucu 4 appraisal well reached total depth in September 2024, with completion expected by mid- October 2024

CPO-5 Block: Production Remains Close to Record Levels

• 3Q2024 average production of 7,721 boepd net (25,738 boepd gross), within 3% of record quarterly production achieved in 2Q2024
• The Cante Flamenco-2 exploration well was spudded in August 2024, targeting the Lower Mirador Formation, with the Ubaque Formation as the secondary objective
• Prospects are being identified from 232 sq km of new 3D seismic

Argentina: Mata Mora Norte Block in the Vaca Muerta Top 10

• Mata Mora Norte Block average production in 3Q2024 was 12,621 boepd gross, 1% higher than 2Q2024, following the put-on production of Pad-4
• Production record of over 3,200 boepd gross at the Mata Mora Norte 2223 well makes it one of the highest producing wells in Vaca Muerta
• Transaction effective date was July 1, Regulatory closing of acquisition is expected in 4Q2024

Llanos Exploration: Drilling Success Increases Production by 28%

• Llanos 123 Block:
  • The Toritos 2 appraisal well drilled in 2Q2024 found pay in the Barco and Lower Mirador formations and is currently producing 790 bopd gross
  • The Toritos Norte 1 appraisal well drilled in 2Q2024, testing the Barco Formation, is currently producing 430 bopd gross
• Llanos 86 and Llanos 104 Blocks (GeoPark operated, 50% WI):
  • Interpretation of seismic data continues, exploratory projects being defined

Ecuador: Intervention Increases Production

• Perico Block (GeoPark non-operated, 50% WI):
  • Production increased 8% versus 2Q2024 to 3,570 gross bopd in 3Q2024, due to increased workovers and well services
  • Performed 2 workovers (Perico Norte 5 and Perico Norte 3) and 1 well service (Perico Norte 2), delivering above plan
• Espejo Block (GeoPark operated, 50% WI):
  • The Espejo Sur B3 and Espejo Sur B1 wells currently producing 675 bopd gross
  • The Espejo Norte A1 exploration well reached total depth in August 2024, targeting the Napo formation. After a few weeks of testing, the well was deemed non-economic and is currently under evaluation

Upcoming Catalysts 4Q2024

• Drilling 3-6 gross wells in 4Q2024 for the base business and 4 gross wells in Argentina, targeting conventional, unconventional, appraisal and exploration projects
• Key projects include:
  • Llanos 34 Block: Drilling one infill well in the Tigui area and an additional well in the Curucucu Incorporating four additional waterflooding injection patterns
  • Mata Mora Norte Block: Developing Pad-9 (four wells), expecting to complete all four horizontal sections in November 2024 and to start production in 1Q2025
  • Confluencia Norte Block (GeoPark non-operated, 50% WI): First exploration pad (three wells) to start production during 4Q2024
  • Llanos 123 Block: Drilling 2 appraisal wells
  • PUT-8 (GeoPark operated, 50% WI): Expected to spud the Bienparado Norte 1 (previously Machaca 1) exploratory well in November 2024
