Celtic Sea Drilling Update

Lansdowne Oil & Gas, ("Lansdowne" or "the Company") welcomes the announcement today by Providence Resources plc ("Providence"), Operator of Standard Exploration Licence 1/11 (Lansdowne 20%),providing a further market update on its ongoing drilling programme on the Barryroe oilfield in the North Celtic Sea Basin, offshore southern Ireland.  The 48/24-10z Barryroe appraisal well is located in c. 100 metre water depth, c. 50 kilometres offshore Ireland.

Drilling Operations

The original drilling timeline was initially set back by weather and later by rig performance issues which significantly delayed the drilling of the 12.25" section. Drilling of this section recommenced on February 2^nd, when the necessary rig repairs and maintenance programmes were completed by the rig owner.  The current well depth is 6,969' TVDSS at the base of the 12.25" section, with all key geological horizons to date having been encountered in line with pre-drill depth prognosis.

Preliminary Results - Secondary Objective

Hydrocarbon shows were encountered during the drilling of the 12.25" section, which contains a number of potential secondary reservoir units. Preliminary real time LWD data demonstrates excellent sandstone package correlation with the nearby 48/24-3 well.

Forward Activities - Primary Objective

The forward programme includes a comprehensive wire-line data acquisition programme of this drilled 12.25"section, utilizing modern 'state of the art' down-hole tools, after which the section will be cased.

Subsequent operations will include coring of the underlying primary reservoir zone, which is the main focus of this drilling programme. Following this, it is planned to carry out drill stem testing of the primary basal sands target in order to ascertain flow rates and productivity.
