Further seismic acquisition in Northern Ireland

InfraStrata plc (AIM:INFA), the independent gas storage and petroleum exploration company, is pleased to announce that Tesla Exploration International Limited ("Tesla") will be undertaking a further infill seismic programme over petroleum licence PL1/10 during June 2012.

The decision to undertake the new survey was taken after completion of the interpretation of 288 kilometres of 2D Vibroseis seismic data acquired during 2011. The PL1/10 partners are very encouraged by the identification of several large leads. The new seismic programme will comprise 100 kilometres of 2D Vibroseis data to refine the structural interpretation over the high-graded leads, and identify a suitable location for drilling the first exploration well.

Commenting on the new survey, Andrew Hindle, CEO of InfraStrata plc said:

"Although it was anticipated that we would confirm a thick sedimentary sequence within the Larne-Lough Neagh Basin, the challenge before the 2011 survey was to design a programme to successfully image below the Tertiary basalt, which is at the surface over the majority of the licence area. We have managed to achieve this and confirm that the structural style is similar to our analogue, the East Irish Sea Basin.

The primary objectives are sandstone reservoirs within the Triassic and Permian sequences, each overlain by saliferous sealing intervals.

We look forward to working with Tesla and local stakeholders to refine the interpretation and progress the project towards the drilling of our first exploration well."
