2) Licence activity synopsis
Following the award of Licence P1345 in Q4 2005, EnCore reprocessed 2 surveys,
AUK 81 and C47-83 2D seismic data to evaluate any potential within the Rotliegend
to the west of the Amethyst Field (Figure 2):
Figure 2 Seismic Database
3. Prospectivity Analysis
The Rotliegend is the primary target in the area. Relatively thin Leman Sand is seen
in the area (50 -120 ft thick). Facies is generally aeolian dunes with multi darcy
permeability. A lead was identified on the 2D data which involved a number of small
faults creating an upthrown structure to the west of Amethyst.

*Potential Reserves
of ~ 100 BCF
*initial estimate only,

as West Amethyst Field
Remapping of the structure following the reprocessing of the data showed the
structure not to be present. Consequently no remaining prospectivity has been
identified on the blocks.
