Comments

Interoil daily average operated production experienced an increase of 88.9 boepd when comparing November with October figures. Production in Argentina increased, while output in Colombia declined.

In Argentina, the operated production increased by 99.7 boepd, mainly due to the reactivation of the pulling rig being successfully operated in some shut in wells last month. In this regard, Interoil would like to emphasise the pulling rig is still working in the reopening of the shut-in wells (according to our pulling program). In MMO the monthly average production is at 38.7 bopd as more wells are being reopened regardless the arrival of the pulling rig.

In Colombia, Puli C production experienced another reduction of 10.8 boepd due to downhole problems in some production strings in Mana wells plus a decrease on Vikingo production in 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.
