Production Summary

• Daily Average Production: Interoil’s total operated production in October averaged 2,239 boepd, reflecting a month-on-month improvement of +157 boepd.
• The increase was primarily driven by operations in Argentina (+196 boepd), while Colombia experienced a decline of -39 boepd.

Country-Specific Highlights
Argentina

• Following the recovery of pre-winter production levels, field teams concentrated on restoring and maintaining compression and generation equipment across multiple sites.
• These efforts successfully reactivated additional wells that had been shut in during the winter, contributing significantly to the overall production increase.

Colombia

• Production for October was limited to the Puli C operation, as the Vikingo Field remained shut in throughout the month due to downhole equipment failure.
• Vikingo-1 Intervention: A downhole intervention during November resulted in an initial production rate of approximately 400 bopd. The current production is 300bopd, a significant increase from the pre-intervention level of 105 bopd.
• Next Steps: The workover rig is being mobilized from the Vikingo site to the Puli C fields and is expected to arrive by the end of the month.
• The Puli C well intervention is projected to span at least three months, with the goal of increasing production by replacing downhole production equipment.
