Comments

In March 2023, unfortunately Interoil’s average daily operated production decreased by 271 boepd where most of the lost production is related with operational issues in Argentina where the austral winter arrived sooner than expected.   Fortunately, Colombia community distress situation was solved, and operations are slowly recovering to its previous figures.

In Argentina, production losses averaged some 350 boepd, mostly from the Santa Cruz fields, due to mild winter temperatures and strong winds causing most of the lost production. Interoil is working hard in solving significant surface production issues related with some obstruction in most of the hydrocarbon pipe network system connecting different gas fields among themselves.

In Colombia, Puli C production experience a slightly increase of 80 boepd as operation was slowly re-established after the community restrictions experience along April. Fortunately, production gradually resume alongside the oil trucking sale. 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.
