Dear Sirs
RE: EP 104/R1 CANNING BASIN, WESTERN AUSTRALIA – THE STOKES BAY-1 WELL
The EP 104/R1 Joint Venture has elected to run 7” (178mm) casing in the well bore to enable testing of the oil and gas shows observed in the Stokes Bay-1 well. Testing will commence from the bottom zones upwards as is standard oilfield practice.
Empire is carried through this programme of casing and testing as part of its EP 104/R1 Farmin Agreement where it is carried through the costs of any completion of the Stokes Bay-1 well.
It is proposed to test the deeper Nullara Formation carbonate section first. The interval of interest is that interval where drilling fluids were lost in the well bore upon deepening the well to the Nullara Formation. This interval is called a lost circulation zone and is indicative of a very porous and permeable reservoir. Testing of the Nullara Formation lost circulation zone is designed to determine whether it is hydrocarbon bearing as it is in the Blina Oilfield, located along the Pinnacle Fault trend 100 kms south east.
Empire, upon electing to go Non-Consent, has minimised risk expenditure of the deeper drilling operations whilst retaining the right to “back in” to any deeper objectives paying the “back in” penalty out of any future oil and gas production, if hydrocarbons are present and they are completed for commercial production.
Testing of the Lower Anderson Formation sands, where several zones are interpreted to have oil saturations, are on the test programme agenda.
It is anticipated that, upon the 7” casing being successfully landed and cemented, the first operation conducted by the Operator will be to test the Nullara Formation lost circulation zone. Further testing through casing of the Lower Anderson Formation will follow upon the EP 104/R1 Joint Venture being provided with that test programme for consideration.
I look forward to providing further details of this exciting test programme in the Stokes Bay-1 well.
Regards

| Proposed Total Depth(measured KB): | 2800 metres |
| Prognosed drilling time: | 15 days |
| Spud Date: | 0930 hrs,WST 3 October 2007 |
| Present Depth at 0600 hrs: | 2755m MD |
| Time of Reporting: | 0600 hrs,WST 25thOctober 2007 |
| Operations Since LastReport: | Since last report on Thursday October 11th, drill pipe conveyedlogging has been conducted. Drillpipe conveyed logs rather thanwireline logs have been run to TD due the angle of the well andhole condition.Preliminary interpretation of these logs indicates:a)The Anderson Sands have some zones with potential oilsaturations. The commercial significance of those zoneswill require formation testing to evaluate. Testing of theAnderson zones would follow operations to evaluate thedeeper Nullara Formation. A joint venture decision ontesting of the Anderson awaits availability of the testprogram and any relevant information to be derived fromtesting the Nullara Fm.b)The top of Nullara Formation has been interpreted at2722m MD. Below 2732m MD, the log quality is severelydegraded by interpreted large scale vugular porosity suchthat quantitative interpretation is not possible.In addition to earlier reported drilling fluid (mud) losses into theNullara section there have been continued losses whileconditioning the well for logging and preparing to case the hole.Because of the losses and subsequent lack of mud and cuttingsreturns, there is no indication of fluid content in the Nullaraporous section. As of 0600 today the wellbore is now properlystabilised and the forward plan is to run 178mm (7”) casing prior |
| to testing the Nullara Formation.As described in last week’s announcement, all JV partners areparticipating in the shallow part of Stokes Bay-1 (above 2589mMD). However, less than all parties are participating in the wellbelow 2589m MD such that equity levels in this part of the StokesBay-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 wellby the payment of penalties out of future production. | |
|---|---|
| Current Operations: | POOH to run Casing |
| Hydrocarbon indications: | Mud gas and oil shows as noted in the Anderson Formation. Noreturns or shows from the Nullara Fm. due to mud losses. |
| Comment: | While the loss of mud to the Nullara Fm has created operationaldifficulties that have now been overcome, we are encouraged bythe presence of both porosity and significant permeability in theNullara reef section. Development of vugular porosity in thissection is a well recognised play, having previously been thetarget of exploration in the Basin, and we note that it is host to oilproduction at Blina some 100km to the SE.The planned test of the Nullara Formation will determine fluidtype and flow characteristics of the reservoir. The Stokes Bayintersection of the Nullara Fm is 80m up dip of the Pt Torment 1intersection which did not have the vugular porosity developed,but nevertheless tested gas at low rates. |
