Comments

In May 2023, Interoil’s average daily operated production increased by 192 boepd compared to the previous month, where most of the additional production comes from the Argentinean operation where the austral winter issues where solved.

In Argentina, there is still some lost production, around 55 boepd, mostly from the Santa Cruz gas associated fields, where some gas compression spare-parts are still pending in the operation causing most of the lost production after an early arrival of a mild winter with strong winds. Interoil is working hard to provide the required compression spare parts to recover the remaining lost production.   In relation to MMO, it should be mentioned that operations have reassumed, and oil storage is being sold domestically prior to start streaming production from the currently shut-in wells.

In Colombia, Puli C production experience a slight increase of 5 boepd as operations were reassumed after the community restrictions experience through April. In the Llanos area, Vikingo production flows decreased by 9.5 boepd following 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.
