Production Summary

Interoil’s daily average total operated production for January was 1,965 boepd, reflecting a decrease of 537 boepd when compared with December.

Decline is primarily attributed to our operations in Argentina (-566 boepd) while operations in Colombia had a modest increase (+ 29 boepd).

Country-Specific Highlights

Argentina

Gas production was primarily affected by the breakdown of two compressor engines, which required the custom fabrication of replacement parts. These parts arrived to the field in February. Consequently, gas production experienced a sustained decrease from January until the repair of the damaged compressors in February.

Colombia

In January, the Vikingo-1 well achieved an average daily production of 196 boepd, effectively offsetting the natural depletion at Puli C and contributing an additional 30 boepd. Currently, the workover rig has completed the intervention of the MN-11 well, the first planned for this campaign in Puli C Fields. This intervention involved the replacement of downhole equipment, including tubing, pump, and rods.

This campaign, which includes at least four additional planned interventions in the Puli C Fields, aims to recover as much as 50 bopd and 600 kscfpd of gas.
