Production Summary

• Operated production increased significantly in both Argentina (+380 boepd) and Colombia (+47 boepd).

Country-Specific Highlights

Argentina

Gas production was primarily affected by the breakdown of two compressor engines. These required the custom fabrication of replacement parts, which arrived at the field in February. As a result, gas production experienced a sustained decrease from January until the repair of the damaged compressors in February. Furthermore in March, a surface equipment maintenance and recovery campaign was carried out, restoring approximately 90bopd of oil production.

Colombia

During March, the Vikingo-1 well averaged 141 boepd. At Puli C, production increased by 51 boepd following the reactivation of previously shut-in wells, which were successfully intervened using a workover rig demobilized on March 27. As of the date of this report, seven wells have been brought back online, delivering a combined flow of 117 bopd—slightly above expectations—and 82,000 scfpd of gas. These gas volumes are expected to gradually increase as the wells stabilize over the coming weeks.
