ASX ANNOUNCEMENT AND MEDIA RELEASE
STOKES BAY-1 ACTIVITY UPDATE
- Stokes Bay 1, Onshore Canning Basin, Western Australia (FAR 8%) Logging conducted; Preparing to run casing prior to testing
FAR has been advised by ARC Energy Limited that drill pipe conveyed logging has now been conducted. Preliminary interpretations are included in the attached well summary report.
Current operations at the well comprise pulling out of the hole to run casing prior to testing the Nullara Formation. The test will determine the fluid type and flow characteristics of the reservoir.
The original planned depth of the well was 2,505mMD. On reaching this depth, the operator proposed deepening the well to approximately 2,800mMD to evaluate the Upper Devonian aged Nullara carbonates. FAR elected to participate at its existing 8% interest.
A Drilling Report on the Stokes Bay-1 well is contained in the attached well summary sheet.
Operator Comment:
“While the loss of mud to the Nullara Fm has created operational difficulties that have now been overcome, we are encouraged by the presence of both porosity and significant permeability in the Nullara reef section. Development of vugular porosity in this section is a well recognised play, having previously been the target of exploration in the Basin, and we note that it is host to oil production at Blina some 100km to the SE.
The planned test of the Nullara Fm will determine fluid type and 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.”

| Operations Since Last Report: |
Since last report on Thursday October 18th, drill pipe conveyed logging has been conducted. Drillpipe conveyed logs rather than wireline logs have been run to TD due to hole condition. Preliminary interpretation of these logs indicates: a) The Anderson Sands have some zones with potential oil saturations. The commercial significance of those zones will require formation testing to evaluate. Testing of the Anderson zones would follow operations to evaluate the deeper Nullara Fm. A joint venture decision on testing of the Anderson awaits availability of the test program and any relevant information to be derived from testing the Nullara Fm. b) The top of Nullara Formation has been interpreted at 2722m MD. Below 2732m MD, the log quality is severely degraded by interpreted large scale vugular porosity such that quantitative interpretation is not possible. In addition to earlier reported drilling fluid (mud) losses into the Nullara section, there have been continued losses while conditioning the well for logging and preparing to case the hole. Because of the losses and subsequent lack of mud and cuttings |

FAR ASX Release 25 Oct 2007 P.3
| returns from TD, there is no indication of fluid content in the Nullara porous section. As of 0600 today the wellbore is now properly stabilised and the forward plan is to run 178mm (7”) casing prior to testing the Nullara Fm. As described in last week’s announcement, all JV partners are participating in the shallow part of Stokes Bay-1 (above 2589m MD). However, less than all parties are participating in the well below 2589m 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 the well by the payment of penalties. |

| Current Operations: | POOH to run Casing |
| Hydrocarbon indications: | Mud gas and oil shows as noted in the Anderson Fm. No returns or shows from the Nullara Fm due to mud loss. |
| Comment: | While the loss of mud to the Nullara Fm has created operational difficulties that have now been overcome, we are encouraged by the presence of both porosity and significant permeability in the Nullara reef section. Development of vugular porosity in this section is a well recognised play, having previously been the target of exploration in the Basin, and we note that it is host to oil production at Blina some 100km to the SE.
