Comments

Interoil’s daily average operated production in June was 1,719 boepd, down 604 boepd compared with figures for May. June’s daily operated production reduction in Colombia drop by 31 boepd (24%), while output from Argentinian fields was down by 571 boepd (76%) compared with the month prior.

In Argentina, the decrease in operated production stems mainly from the Santa Cruz fields, where harsh winter conditions impacted the Patagonian region with temperatures reaching 20°C below zero. These events blocked national routes and oilfield paths, and the local authorities issued roadblocks as a safety measure, making it difficult to access services and materials to the operations. The pulling rig and some oilfields had to be postponed, due to road access impediments and safety considerations.   These extreme weather conditions are expected to continue during July. In Mata Magallanes Oeste (MMO), the monthly average production reached 25 bopd.

In Colombia, production in Puli C had a slight decrease of 8 boepd in line with natural reservoir depletion in Mana, Rio Opia and Ambrosia fields. The company is working with local communities in the Puli C surroundings aiming to grant their approval to initiate a pulling campaign to recover at least 100 bpd of oil and 500 Kscfpd of gas outflows. The Vikingo production experienced a production reduction of 23 bopd showing that its downhole equipment is experiencing a 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.
