Celtic Sea Drilling Update

Lansdowne Oil & Gas, ("Lansdowne" or "the Company") welcomes the announcement today by Providence Resources plc ("Providence") of the award of Standard Exploration Licence (SEL) 1/11 over the Barryroe area, in which Lansdowne has a 20% working interest.

As noted by Providence, the area of SEL 1/11 is larger than held previously under Licensing Option 08/1, an increase of some 25 sq km, with the extra area lying on the northern side of the concession where additional potential has been recognised. Providence has also updated details of the forthcoming Barryroe appraisal well, 48/24-J, the location of which has been finalised using the new fast-track 3D seismic data and which is expected to commence drilling operations in mid November. The Licence is for a period of up to 6 years, split into two 3 year phases, the appraisal well will fulfil the drilling commitment for the first phase of the licence. It is planned to test the well using vacuum insulated tubing which has been demonstrated to be effective when dealing with high pour point crudes such as those seen in the original well.

 Commenting on the announcement Dr. Steve Boldy, CEO of Lansdowne said:

 "The award of Standard Exploration Licence 1/11, brings the number of Licences held by Lansdowne in the shallow water North Celtic Sea Basin to five. These Licences, along with Licensing Option 09/1, cover close to 500,000 acres held by Lansdowne in this underexplored basin with proven petroleum systems. We believe the application of 3D seismic will provide the key to unlocking the potential of the basin and we look forward to the drilling of the Barryroe appraisal well in November"
