Comments

Interoil’s daily average total operated production in September ended at 2,082 boepd, showing a significant improvement from August (+857 boepd). This increase was primarily due to the recovery of Argentina’s production, which had been affected by severe winter conditions. In Colombia, production decreased slightly by 22 boepd, while in Argentina, production surged by 879 boepd.

In Argentina, production in August was severely impacted by winter weather, which obstructed roads and prevented movement, leading to the shut-in of a significant portion of production. With the arrival of spring, field personnel were able to return to operational duties, resulting in production returning to pre-winter levels in September. The company continues efforts to sustain and further increase production in the current month.

In Colombia, production at Puli C decreased in September, primarily from the Mana field, while Vikingo-1 remained out of production. The workover rig has been delayed due to a pending oversized load permit from local road transit authorities. The replacement of the downhole production system in Vikingo began in October, and the work program is expected to last 10-15 days, assuming no further delays.
