ERRINGTON-1: EXPLORATION WELL, PEDL 028, ONSHORE UK (ROC: 100% & Operator)

As at 6:00am on 3 January 2005 UK time, the Errington-1 exploration wildcat well
was drilling ahead in 8 1/2 inch hole at a depth of 1,559m. On the basis of data
collected while drilling, the well has drilled through the shallower objective
without any obvious indications of significant hydrocarbons. The well is now
drilling ahead toward the deeper objective. A full evaluation of the intervals
drilled to date will be undertaken when the well reaches Total Depth and
wireline logs are run.
Errington-1 is located in PEDL 028 approximately 35 km west of Newcastle in
northern England.
