Comments

In March 2023, unfortunately Interoil's average daily operated production
decreased by 317 boepd where most of the lost production is related with
community's blockage to our operations in Colombia and union strikes in
Argentina.   Fortunately, both social distress situations have been solved and
operations are slowly recovering in Argentina and Colombia.

In Argentina, production losses averaged some 246 boepd, mostly from the Santa
Cruz fields, due to a strike held by field personnel. The recovery to pre-strike
production levels is expected to last until mid-May this year as most of the
producing fields are below their output potential waiting for surface equipment
repairing in a period where winter is starting to hit the southern hemisphere.

In Colombia, Puli C production decreased due to community restrictions blocking
not only the arrival of the pulling rig but also the arrival of the selling-oil-
trucks affecting oil production as Mana Storage Tanks were coming to its full
capacity. Fortunately, in mid-April, Interoil was able to remove the blockade
and gradually resume production. 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 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.
