lilac drilling update

Roc Oil (WA) Pty Limited, a wholly owned subsidiary of ROC, advises that since its last Stock Exchange Release on 4 February 2008, the Lilac-1 exploration well in WA-286-P, in the North Perth Basin, offshore Western Australia, has drilled to a Total Depth of 1455 mBRT and wireline logging is underway.
The Lilac-1 exploration well encountered sands with weak gas shows and fluorescence. However, preliminary interpretation of mud log, Logging While Drilling (LWD) and drill data indicates that the primary reservoir is water bearing. A final analysis will be made once wireline logging is completed. It is expected that the well will be plugged and abandoned.
The forward programme for the Premium "WilCraft" jack-up drilling rig is to move to the second well of the current programme, Frankland-2, also in WA-286-P. Frankland-2 will appraise a structure about one kilometre northeast of Frankland-1 which discovered gas in 2007. Frankland-2 is expected to be completed by the end of February 2008.
