Comments

Interoil total daily average operated production experienced a slight improvement of 13.04 boepd when comparing December with November figures, this increment in production is mostly coming from the Argentinean operations which even compensate a reduction in the Colombian flowrate.

In Argentina, the operated production increased by 25.61 boepd where 73% of this increment comes from the Santa Cruz Exploitation Assets and the remaining 27% comes from Mata Magallanes Oeste (MMO) Field. In this regard, Interoil would like to emphasise the pulling rig is still engaged in the reopening of the shut-in wells following pulling program. In MMO the monthly average production reached 58.8 boepd as more wells are on stream after fixing their surface production engines.

In Colombia, Puli C production experienced an increase of 10.64 boepd after solving asphaltenes formation in some production strings in Mana wells. Vikingo production experienced a reduction in its flowrate by 23.2 boepd line with the expected natural depletion. 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.
