Comments

In October 2022, the average daily operated production from fields in Argentina
and Colombia combined increased by 212 boepd, an increase of around six percent
from September. Most of this increment comes from the Argentina operation, +207
boepd, whereas the Colombia operation increased +5 boepd as explained below.

In Argentina, production at the Santa Cruz operated fields increased, with the
Oceano and the Cerro Molino fields accounting for most of it. This is the result
of surface work done on the oil surface facilities undertaken last month in
Oceano plus paraffins and asphaltenes removal campaign taken in Cerro Molino
Field during the early days of October.

In Colombia, Puli C production increased from the previous month, especially in
the Mana Field where some chemical injection treatments were performed in Mana
Facilities.

In the Llanos area, Vikingo production decreased around 4 bopd from Carbonera 5
formation following 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 process
are ongoing.
