ASX ANNOUNCEMENT AND MEDIA RELEASE
STOKES BAY-1 ACTIVITY UPDATE
- Stokes Bay 1, Onshore Canning Basin, Western Australia (FAR 8%) Preparing to Complete the Well Prior to Testing
FAR has been advised by Arc Energy Limited that since our last report on Thursday October 25th, 178 mm (7 inch) casing has been run to a depth of 2585m measured depth (MD), and the well deepened a further 22 m from the previous 2755 m to 2777 m MD.
In view of persistent ongoing mud losses, that are now under control, and the accumulating evidence of gas presence in the Nullara, the Operator has recommended to the JV to complete the well (rather than the previously proposed open hole DST) in order to test this interval. The current plan is to complete the well during the next two days, and commence testing operations.
Current operations at the well comprise pulling out of the hole to run completion.
A Drilling Report on the Stokes Bay-1 well is contained in the attached well summary sheet.
Operator Comment:
“The loss of mud to the Nullara Fm has continued to create operational difficulties that have delayed testing the interval. However, we remain very encouraged by the presence of both porosity and significant permeability in the Nullara reef section, and the more recent intermittent gas shows when mud circulation is established are also viewed positively.”

STOKES BAY-1 DRILLING REPORT CANNING BASIN, WESTERN AUSTRALIA
| Date: | 1stNovember 2007 |
|---|---|
| Permit: | R1 |
| Well Location: | Lat : 17o08’ 23.46”S Long : 123o42’ 32.40”E |
| Directional offset to target: | 1024 metres |
| Elevation: | Ground Level is 12.4mAMSL Rotary Table is 18.1mAMSL |
| Proposed Total Depth (measured KB): |
2800 metres |
| Prognosed drilling time: | 15 days |
| Spud Date: | 0930 hrs, WST 3rdOctober 2007 |
| Present Depth at 0600 hrs: | 2777m MD |
| Time of Reporting: | 0600 hrs, WST 1stNovember 2007 |
| Operations Since Last Report: |
Since last report on Thursday, October 25th, 178 mm (7 inch) casing has been run to a depth of 2585m measured depth (MD), and the well deepened a further 22 m from the previous 2755 m to 2777 m MD. In drilling the additional 22 m, further losses of mud at a rate of approximately 250 bbl/hr were experienced. This resulted in no fluid or cuttings returns to surface. In drilling the 22 m of additional hole, several metre-scale intervals of very high penetration rates were encountered, these being interpreted to be due to additional large scale vuggy porosity. Since reaching a total depth of 2777 m MD, efforts have focussed on curing the ongoing fluid losses in the Nullara Fm. This has resulted in intermittent establishment of circulation, and returns to surface with associated intermittent mud gas peaks of up to 10%. In view of the persistent ongoing losses that are now under control, and the accumulating evidence of gas presence in the Nullara, the Operator has recommended to the JV to complete the well (rather than the previously proposed open hole DST) in order to test this interval. The current plan is to complete the well during the next two days, and commence testing operations. |

FAR Ltd ASX Release 1Nov07 P.3
| As previously reported, all JV partners are participating in the shallow part of Stokes Bay-1 (above 2589 m MD). However, less than all parties have participated in the well below 2589 m MD such that equity levels in this part of the Stokes Bay-1 well (below 2589m MD) are: • ARC Energy Limited 69.25% (Operator) • Emerald Oil & Gas NL 12.75% • Pancontinental Oil & Gas NL 10.0% • First Australian Resources Limited 8.0% Under the Joint Venture Operating Agreement, the non- participating parties in the deeper part of the well (Empire, Phoenix and Indigo) retain a future right to earn back into their respective participating interests by the payment of penalties out of future production. |

|---|---|
| Current Operations: | POOH to run Completion |
| Hydrocarbon indications: | Mud gas readings of up to 10% have been recorded at surface from intermittent circulation during attempts to cure lost circulation |
| Comment: | The loss of mud to the Nullara Fm has continued to create operational difficulties that have delayed testing the interval. However, we remain very encouraged by the presence of both porosity and significant permeability in the Nullara reef section, and the more recent intermittent gas shows when mud circulation is established are also viewed positively. The planned test of the Nullara Fm will determine fluid content and potential flow characteristics of the reservoir. The Stokes Bay-1 intersection of the Nullara Fm is 80m up dip of the Pt Torment-1 intersection which did not have the vugular porosity developed, but nevertheless tested gas at low rates. |
