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

                            Re: Share Price Movement

SOCO notes the recent movement in the Company's share price and can confirm that
drilling is still in progress on the Te Giac Den sidetrack well  ('16.1-TGD-1X-
ST1'), the deep high pressure, high temperature well on Prospect 'E' in Block
16-1, offshore Vietnam.  SOCO has no information about the future results of 16-
1-TGD-IX-ST1 at this stage, but an update on the status of the well is provided
below.

The well is currently drilling in the Oligocene clastics with an estimated 80
metres of clastics to drill before reaching the top of Basement. The plan is to
drill a few metres into Basement and then run logs and pressure tests. We would
then expect to set a seven inch liner before drilling further into Basement.
This is in accordance with the pre-drilling plan should hole conditions and
up-hole information support drilling into Basement.

Information gathered while drilling through the Oligocene section is
insufficient at this point to determine the likelihood that this interval would
or would not be productive. The higher mud weights mean that the hydrocarbon
shows are not as pronounced as those in the same zones in the original well
bore.  There are also some stratigraphic variations between the well bores,
which is similar to the results from analogous wells in the basin.

Once the liner is in place, the well will be drilled approximately 300 to 500
metres into Basement after which the Company would expect to make another
release regarding the testing programme.  The casing operation and drilling is
expected to take approximately three weeks, barring operational difficulties.
