                          ("MedOil" or "the Company")

                       COMMENCEMENT OF 3-D SEISMIC SURVEY

The Directors of MedOil plc, the oil and gas exploration company geographically
focused on southern Europe and North Africa, are pleased to announce that the
3-D seismic survey at its Louza Permit in Tunisia has now commenced.

The 3D seismic survey work programme is being managed by strategic partner
TGS-NOPEC ("TGS"), the international seismic acquisition and processing company.
On MedOil's behalf, TGS will conduct a 600 sq. km. 3D seismic survey to
accurately map the oil volume potential of the M'Sela -1 'Abiod Formation' oil
discovery. The survey will also cover four other separate exploration prospects
in the area, and a potentially large stratigraphic trap in the 'Isis Formation'
which tested oil in the discovery well and was the producing strata in the
nearby Isis oil field.

The programme is designed to add confidence to the technical analysis of the
defined prospects; determine the location of a near-term appraisal drilling
programme around the oil discovery; and examine the upside potential of the
M'Sela stratigraphic oil trap.

The seismic vessel carrying out the survey is owned by Norwegian-based Scan
Geophysical Co. The vessel, called Scan Resolution, was recently upgraded at the
Szczecin shipyard in Poland. As long as weather conditions remain fair, it will
acquire 20 square kilometres per day of data and the survey will take 4-6 weeks
to complete.

Regarding activities in Malta, MedOil remains in negotiations with the Maltese
authorities for a one year extension period to the original Exploration Study
Area (ESA) agreement.

Commenting on today's update, MedOil's Chief Executive Officer, David Thomas,
said: "We are delighted that the seismic survey has commenced. The acquisition
of the 3D technical data should provide some important results for MedOil, and
we look forward to updating the market in the coming months. Meanwhile, the
Company continues to pursue high impact exploration targets in the Mediterranean
area."

Notes to Editors:

Tunisia - Louza Permit

The 4,100 sq. km. permit is located offshore central Tunisia. There is an
existing oil discovery on the permit which flowed 1,200 barrels per day of 34
gravity oil from one reservoir, and 118 barrels per day of 16 gravity oil from a
deeper reservoir unit. Four other un-drilled prospects lie close to the
discovery well. MedOil has a 95% interest in the permit, with TGS-NOPEC having a
5% interest.
