The well is currently being suspended in preparation for testing with a rig-less testing unit following completion of a testing program currently underway at AT-5.

AT-6 is the third well in the current appraisal campaign on the Ain Tsila gas discovery.

This is a vertical well targeting a broad culmination in the South East of the Ain Tsila Field outside the 3D seismic survey area, about 17 kms south east of the AT-4 well location.

The principal objective of the well was to extend the proven gas in place and to test the reservoir quality towards the mapped south eastern limit of the field.

The Ordovician reservoir was encountered as expected with good gas shows and a full suite of logs was run.

Initial log interpretations indicate a gross Ordovician reservoir interval of 168m and a net pay interval of 45m, the company said.

Petroceltic chief executive Brian O’Cathain said the initial results from the AT-6 well are very encouraging and increase the proven area of the Ain Tsila field considerably to the southeast with this large step-out.
