Restoring Indico Field Production in the CPO-5 Block

Second Exploration Success in the Llanos 123 Block

New Exploration Success in Ecuador

GeoPark Limited (“GeoPark” or the “Company”) (NYSE: GPRK), a leading independent Latin American oil and gas explorer, operator and consolidator, provides an update on operations in the CPO-5 (GeoPark non-operated, 30% WI), Llanos 123 (GeoPark operated, 50% WI-Hocol 50% WI), Llanos 87 (GeoPark operated, 50% WI-Hocol 50% WI), Llanos 34 (GeoPark operated, 45% WI) and Perico (GeoPark non-operated, 50% WI) blocks.

Colombia

Production Back Online in the CPO-5 Block

In late September 2023, the operator of the CPO-5 block received approval from the regulator (Agencia Nacional de Hidrocarburos, ANH) to resume production at the Indico 6 and Indico 7 wells.

The Indico 7 well restarted production in late September 2023 and is gradually increasing its production, targeting to reach 4,000 bopd gross in the next few days. The Indico 6 well restarted production on October 1, 2023 and is also expected to gradually increase its production to approximately 4,000 bopd gross.

The Indico 6 and Indico 7 wells have the potential to increase and stabilize their combined production at approximately 9,000 bopd gross before year-end, depending on reservoir performance.

These two wells were drilled in late 2022 and have been shut-in¹ following the ANH request that the operator suspend production until certain required surface facilities were completed.

Current Drilling Activities in the CPO-5 Block

The operator spudded the Halcon 1 exploration well on September 29, 2023, targeting the exploration potential of the Barco (Guadalupe) formation in the northern part of the CPO-5 block, closer to the southern part of the Llanos 34 block.

New Exploration Success in the Llanos Basin

Llanos 123 Block – Second Exploration Success

The Toritos 1 exploration well reached total depth in September 2023 with logging information indicating hydrocarbon potential in the Barco (Guadalupe) and Gacheta formations. Testing activities are ongoing and the well is currently producing approximately 1,400 bopd of 14 degrees API with a 1% water cut from the Barco (Guadalupe) formation. 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.

The Saltador 1 well² was the first exploration success in the Llanos 123 block. It continues to produce approximately 765 bopd of 16 degrees API with 3% water cut from the Barco (Guadalupe) formation.

The Llanos 123 block is currently producing over 2,100 bopd gross, and its production is already being delivered to GeoPark’s off-takers.

Based on these positive results, GeoPark is adding a new exploration well in the Llanos 123 block, the Bisbita Centro 1 well, targeting an exploration prospect located 1.5 km south of Saltador 1, to be spudded in early 4Q2023 (subject to joint venture approval).

Current Drilling Activities in the Llanos 87 Block

GeoPark is targeting to spud the Zorzal Este 1 exploration well this week, which is expected to reach total depth in mid-November 2023.

Horizontal Well Drilling Campaign in the Llanos 34 Block

In the Llanos 34 block, GeoPark drilled and completed the third horizontal well which is currently initiating production tests in the Mirador formation.

This well was drilled 36% faster, with 18% lower drilling costs, and a 172% longer lateral length compared to the first horizontal well.

GeoPark already spudded the fourth horizontal well, expected to reach total depth in early-November 2023. A fifth horizontal well is expected to spud by mid-October 2023.

Ecuador

New Exploration Success in the Perico Block

The Perico Centro 1 exploration well reached total depth in September 2023 with preliminary logging information indicating hydrocarbon potential in the U-sand formation. The well was completed and is initiating testing with current production of approximately 800 bopd of 28 degrees API with 1% water cut.

The Yin 2 well reached total depth in late July 2023. Preliminary logging information confirmed development potential in the Hollin formation and also encountered a new zone with 40 feet of potential net pay in the U-sand formation. The Yin 2 well started production tests by mid-August 2023 and is currently producing approximately 767 bopd of 30 degrees API with 1% water cut from the U-sand formation.

Based on these positive results, GeoPark and its joint venture partner are adding a new appraisal well, the Perico Norte-4, to be spudded in early-October 2023.

GeoPark plans to publish its 3Q2023 operational update in mid-October 2023.
