Comments

Total daily average oil production increased by 5.6 percent to 941 bopd in March compared to February, driven mainly by an increase in output from the Mata Magallanes Oeste (MMO) field, where minor repairs of surface equipment were undertaken in March.

The workover rig which will be engaged in the work to reopen the first 15 wells at MMO, has been inspected, certified, and accepted by Interoil.

In Colombia, the Vikingo well flowed steadily through the month, while production from the mature Puli C field continued to decline, resulting in a reduction in daily output of around 1.5 percent. As stated before, a pulling rig will be used to repair equipment in several Puli C wells in an effort to restore production at this field.

Drilling of the Mazorca well in the Altair field is somewhat delayed due to protracted negotiations with local communities, which is undertaken in consultation with authorities.
