                             SOCO International plc
                           ('SOCO' or 'the Company')

                          Vietnam TGX-1X Well Results


SOCO is an international oil and gas exploration and production company,
headquartered in London, traded on the London Stock Exchange and a constituent
of the FTSE 250 Index. The Company has interests in Vietnam, Yemen, Thailand,
the Republic of Congo (Brazzaville) and the Democratic Republic of Congo
(Kinshasa) with production operations in Yemen.

After encountering reservoir sands, the first exploration well on the Te Giac
Xang ('TGX') structure on Prospect 'K' will be plugged and abandoned as initial
analysis indicates that it was not drilled within structural closure.  Full
analysis of logs and other data will take several weeks to complete. Prospect 'K
' is a subtle closure to the west of the higher amplitude Te Giac Trang ('TGT')
structure. The seismic over the area will be reprocessed and remapped to better
define the structure for a possible second well.

Located in a previously untested portion of the Clastics fairway on Block 16-1,
the TGX-1X well was drilled to a depth of 3,506 metres.  Finding reservoir is
the main risk in drilling in this fairway, so the presence of reservoir in
TGX-1X is a positive indicator for future success as drilling locations step out
from the initial discovery.  As has been the case on every well drilled in the
Clastics fairway by the Hoang Long Joint Operating Company ('HLJOC'), having oil
sourced was not an issue.

To date, the HLJOC has had a 50% success rate in exploration/appraisal wells
drilled in the fairway on Block 16-1, with discoveries ranging from 9,340
barrels of oil equivalent per day ('BOEPD') to 17,500 BOEPD and a declaration of
commerciality is expected early in 2007 on the TGT field.  Hoan Vu JOC is
proceeding to development on the Ca Ngu Vang field on Block 9-2.

The rig will finish logging this well and rig down as soon as weather permits to
move to the 'H2' fault block on the TGT structure where it will spud the TGT-5X
well.  Another rig is under contract to begin drilling in the first or second
quarter of 2007.  A letter of intent has been signed for a third rig and
contract negotiations have begun.  The rig under contract and the rig expected
to be contracted are for one firm, plus one optional year of drilling.


Ed Story, President and Chief Executive of SOCO, commented:

'Although this well was not a commercial discovery, we did gain some positive
encouragement for further exploration in the 16-1 fairway as far as reservoir
development and oil source are concerned, moving away from the initial
discovery.  Accordingly, our view on resource potential is not impacted, but the
well results reinforce the risk profile of exploratory drilling, even in an
excellent setting.  We will further refine our seismic to improve trap
definition as we carry out a continuous drilling programme for the next fourteen
months.'
