GeoPark Limited announced its independent oil and gas reserves assessment as of December 31, 2025, certified by DeGolyer and MacNaughton Corp. under PRMS methodology. The company reported a 38% year-over-year increase in total 2P reserves, driven mainly by the addition of 36.7 million barrels of oil equivalent (mmboe) in Argentina. The 2P Reserve Replacement Ratio reached 430%, with net additions from acquisitions, after divestments, contributing 31.2 mmboe to 2P reserves. GeoPark's certified 1P reserves totaled 69 mmboe and 2P reserves totaled 121 mmboe, the highest level since 2022. The 1P Reserve Life Index $(RLI)$ was 7.2 years and the 2P RLI was 12.7 years. The company reported a 2025 finding, development, and acquisition (FD&A) cost of $4.3 per barrel of oil equivalent on a 2P basis. In Colombia, 2P reserves increased by approximately 2.6 mmboe, mainly due to technical revisions and new discoveries in the CPO-5 and Llanos 123 blocks, as well as enhanced recovery initiatives. GeoPark continues to advance its Vaca Muerta development plan, with a new drilling program scheduled for the second half of 2026 and a production target of 20,000 barrels of oil equivalent per day by 2028.
