DNO is pleased to announce an update on the reserves assessment on UK
block 211/22b


On the UK license, P1067 - block 211/22b, DNO has completed an
interpretation of the license potential based on re-evaluation of
well 211/22-2 data.

The well was drilled, logged and cored in 1977 by Sun Oil, however no
drill stem test was undertaken at the time. Based on a full
re-evaluation of available log and core data, as well as correlation
with neighbouring wells, the well is considered to be a discovery of
a 20 m oil column within the Brent Group. This is now identified as
the Mulle discovery, estimated to contain gross recoverable reserves
between 4mmboe (low) and 36mmboe (high), with a mid case of 17mmboe
within the P1067 licence.

The licence group will now focus on maturing the discovery further
including a possible appraisal well. The objective will be to develop
the discovery as a sub-sea tie-in to neighbouring infrastructure,
existing or planned.

The Mulle prospect is located downdip of the Causeway Field operated
by Antrim Energy.

The licensees of block 211/22b (P1067) are DNO (50%, Operator),
Elixir Petroleum (40%) and Rocksource UK Ltd (10%).  The licence was
awarded in the UKCS 21st Licensing Round and was renewed in September
2007.
