Comments

Interoil’s total daily average operated production in May decreased by 255 boepd compared with previous month. This reduction is mainly coming from the Argentinean fields whereas Colombia continues experiencing a slight reduction of flows in lined with production forecast.

In Argentina, the operated production had 255 boepd reduction. The reopening pulling program in the Santa Cruz wells is still ongoing as programmed. In Mata Magallanes Oeste (MMO), the monthly average production reached 31 bopd.

In Colombia, production in Puli C decreased 3 boepd because of the natural depletion experienced on the flowing wells in Mana, Rio Opia and Ambrosia Fields. In the same line, the Vikingo production experienced a production reduction of around 13 bopd as its downhole equipment might be experiencing an accelerated worn-out due to its current working parameters.

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.
