BNG Deep Well operational update
Deep Well 801
As previously announced we successfully completed a 350 meter
side-track from a depth of 4,501 meters by-passing the blocked
pipe. A 5-inch liner was run to the new bottom of the borehole at a
Total Depth of 4,852 meters.
Also as previously announced while drilling the side-track we
detected four potentially oil-bearing intervals. The first of 6
meters between 4,535 and 4,541 meters; the second is of 20 meters
between 4,554 and 4,574 meters; the third is of 59 meters between
4,635 and 4,694 and the fourth is of 36 meters between 4,812 and
4,848 meters.
We are pleased to update the market with news that 75 meters of
the identified intervals have been perforated.
The drilling fluids used to contain the high pressure in the
well have been progressively changed to lighter density fluids in
preparation for acidizing the perforated reservoir intervals. The
acid work is expected to clean up any borehole damage caused in the
perforating process and enhance the permeability of the
reservoir.
Further announcements will be made in due course.
Deep Well A5
As previously announced we already have an operational rig on
site at Deep Well A5. The drilling mud previously used at Deep Well
801 is being readied for use in the conventional drilling planned
to clear the obstruction that caused a suspension in the 90-day
flow test.
Once the drilling is complete we plan to run tubing to the
bottom of the well, after which a new 90-day flow test would
commence.
Pressure in the well remains stable at around 450 bar at the
wellhead, which suggests there is still good communication
throughout the length of the well.
Deep Well A6
As previously announced, our plan with Deep well A6 remains to
re-perforate the well using more powerful explosive charges.
The drill pipes to be used in this operation have been in use at
Deep Well 801 and will be moved to Deep Well A6 once the current
operations at Deep Well 801 are concluded.

Comments
Clive Carver, Executive Chairman said
"We are at the final stages of the complex operation to get Deep
Well 801 to flow and we remain confident of a positive outcome,
although given past delays nothing is being taken for granted. We
look forward to making further reports as soon as reliable
additional information is available."
