Interoil Exploration & Production ASA: Colombia drilling program update

   Interoil Exploration & Production ASA: Colombia drilling program update

The results of the MN-13SH Doima well show an initial production of 100 bopd
and 105 boepd, which is above our expectations of 85 bopd. The well was
drilled to 3,048 ft and 66 ft of net sands were selected for perforation. GOR
was 532 scf/stb, 22 API oil gravity with 0.74 % BSW.

The results of the MN-34 Monserrate well show an initial production of 45 bopd
and 79 boepd. The well was drilled to 4,615 ft and 318 ft of net sands were
selected for perforation. GOR was 4,219 scf/stb, 24 API oil gravity with 0.78
% BSW.

The results of the MN-12SH Doima well show an initial production of 10 bopd,
well below our expectations of 85 bopd. The well was drilled to 2 740 ft and
74 ft of net sands were encountered. GOR was 0 scf/stb, 24° API oil gravity
with 0.0% BSW.

As the top three layers of the reservoir were gas bearing, only the lower
interval (20 ft) was perforated in order to avoid a depletion of pressure that
would have a detrimental effect on the production from neighbouring wells.
This explains the disappointing results.

Due to the encountering of gas on the MN-12SH, the last two Doima wells of the
campaign have been replaced with two new wells, MNS-12 targeting the Monserate
reservoir and MN-17SH targeting the Doima reservoir.

To date, nine wells of the 12-well drilling campaign has been completed.
