                         ROC OIL COMPANY LIMITED ('ROC')
                             STOCK EXCHANGE RELEASE

                    ACTIVITY UPDATE: PRODUCTION NORTH SEA -
                    FIRST OIL FLOWS FROM THE BLANE OIL FIELD

ROC's wholly owned subsidiary, Roc Oil (GB) Limited, is pleased to advise that
on 12 September 2007, the Blane Oil Field started production. Gross production
rates are expected to quickly rise to approximately 17,000 BOEPD (ROC: 2,125
BOEPD), almost entirely oil. Blane is tied back to the BP-operated Ula Oil
Field, 34 kilometres to the northeast in Norway, from where the oil will be
transported via a sub-sea pipeline to the Teeside Oil Terminal in the UK.

The Blane Oil Field, operated by Talisman Energy (UK) Limited, is located in UK
Block 30/3a and Norwegian Block 1/2, about 260 kilometres east of Aberdeen.
Because the field straddles the UK and Norwegian international boundary it has
been unitised: 82% (UK) and 18% (Norway). As previously reported the field's
gross proved and probable (2P) reserves are estimated to be 30.4 MMBOE (ROC:3.8
MMBOE), 97% oil.

Commenting on the Blane start-up, ROC's Chief Executive Officer, John Doran
stated that:

'Blane further diversifies ROC's production base which now comprises oil
production, from six fields in four countries. Coming along behind Blane during
the next year or two are field developments offshore China and appraisal
projects relating to recent discoveries offshore Western Australia and onshore
Angola.'

Roc Oil (GB) Limited.......................................................12.5%
