Comments

In November 2022, the average daily operated production from fields in Argentina and Colombia combined decreased by 186 boepd, a reduction of less than six percent compared with October. This is explained by some operational changes in Argentina especially in the Santa Cruz operation.

In Argentina, a slight decrease in production was recorded in the Santa Cruz fields where the Chorrillos Field accounted for most of it. This reduction in production is in direct relationship with a planned maintenance program on the surface gas treatment facility, especially in the Cerro Norte Field.

In Colombia, Puli C production decrease especially in the Mana Field due to some restriction issues related with paraffins and asphaltenes blocking some surface production lines as weather brought winter temperatures in the area. In the Llanos area, Vikingo production flows remained stable following at its natural depletion rate. The exploration campaign in Altair and LLA-47 blocks remains on hold and pending approval from local authorities. Conversations with the ANH concerning the formal approval is still on hold waiting for the new authorities to take position.
