The Carnarvon Basin is currently Australia’s most prolific oil and gas producing Basin. The basin contains approximately 50 producing fields and about 30 undeveloped fields. Another 30 discoveries are held under Retention Leases. The developed gas fields range in size from less than 100 Bcf (onshore or near shore) to over 10 Tcf while developed oil fields may vary from less than 1 million barrels for developments near existing infrastructure to greater than 100 million barrels for stand-alone developments.
Strike has a large acreage position in the shallow water area of the basin with favourable locations for oil and gas migration. The permits contain sub-economic hydrocarbon discoveries such as the Chamois and Leatherback oil fields as well as a number of undrilled exploration prospects.
In 2007 the Commonwealth of Australia - Department of Defence commissioned Strike to undertake a Front End Engineering and Design (FEED) study to investigate the feasibility of supplying gas from the undeveloped Rivoli gas field (EP-325) to the Defence Communication Station near Exmouth.
Highlights for April to June 2008:
Efforts continued to secure a suitable, cost effective drilling rig for drilling in the shallow waters of the Carnarvon Basin. The first well planned to be drilled will be on the Baniyas Prospect (prospective resource size of Pmean to P10 of 61 to 111 bcf of gas).
The Department of Defence is considering a proposal to supply gas from the Rivoli gas field (Strike Oil WI: 44.5%) to its communications station located north of Exmouth. In the meantime the Department of Defence continues to fund further work including the gathering of environmental information to ensure an early and comprehensive stakeholder engagement upon project sanction.
Planned for July to September 2008:
Progress the development of the Rivoli gas field, in the Carnarvon basin.
As operator for the majority of its interests in the basin, Strike is actively involved in development of a number of prospects to a drillable stage.

Why Strike Oil is exploring in the Carnarvon Basin.
- Australia´s most prolific oil and gas producing basin, lowers exploration risk;
- significant oil and gas infrastructure facilitates rapid development;
- offshore drilling and development costs are amongst the lowest in Australia;
- high quality acreage available in water depths suitable for the use of jack-up rigs (less than 80 metres) and proven development technology or other innovative drilling/production solutions
- large quantity of high quality historic seismic and well data available, lowers costs and risk; technical and management staff with many years of first-hand experience, shortens learning curve.
