Comments

In January 2023, the combined daily average operated production from fields in Argentina and Colombia declined by 697 boepd compared with the previous month. Output has declined over the past three months due to a combination of downhole lifting equipment failure and operational issues in Argentina and Colombia, as explained below.

In Argentina, production in all the Santa Cruz fields declined due to some delays during repair of surface infrastructure plus the reopening of producing wells, which took longer than expected after two-month union strike. The recovery to pre-strike production levels is expected by the end of February.

In Colombia, Puli C production declined as community restrictions were blocking nearby access roads, thereby delaying the arrival of production related products and downhole production equipment required prior to the arrival of the pulling rig. This pulling rig is expected to arrive at the first well site in the second half of March.

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.
