The Cheshire Basin comprises a thick Permo-Triassic sequence unconformably overlying a Carboniferous (Westphalian) coalfield. Numerous thick coals are present at outcrop around the periphery of the Cheshire basin and the presence of deep coals beneath the Permo-Triassic had been proven during exploration for conventional hydrocarbons.

In 2009 Composite Energy successfully completed a cored exploration well in PEDL188. The well reached a total depth of TD of 4,990' and recovered 1,862' of 3" diameter core with a core recovery of approximately 97%.

A total of 34' of net coal was recovered in the core although analysis of the wireline logs indicates actual net coal approaches 40'. Maximum recorded seam thickness was 5.2' and at least two completeable intervals greater than 7' thick are present.

Dry ash free (DAF) gas contents for completeable coal seams range from 260scf/ton to 314 scf/ton.

Composite is evaluating future exploration and pilot development opportunities for this promising area.
