Current interpretations suggest the presence of five Devonian reef building cycles in EP 104 with a further two in the Ordovician, Nita, and Willara formations. The possible Devonian reefs occur in the NVorral, Lower and Upper Pillara, Virgin Hills, and Nullara carbonate cycles. Minor buildups may be present in the Fairfield and Laurel formations.The Upper Pillara reef complex was subaerially exposed and partly eroded for a period of 10 to 50 million years, following the Early Frasnian 'Tappers Inlet orogeny'. Large potential hydrocarbon reservoirs were created by the secondary mega-porosity formed during this period, and these were sealed by the regional Laurel transgression in the Early Carboniferous. This mode of porosity enhancement is applicable to all the potential reef cycles, as varying degrees of unconformity mark their upper boundaries, generally followed by onlap of sealing lithologies. The Upper Pillara cycle is considered the most prospective of the Devonian carbonate cycles which were the main targets in the first five wells.In response to the success of Home Energy Co. Ltd at Sundown, the last four wells in EP 104 have had Permo-Carboniferous objectives. This drilling resulted in the discovery in 1982 of the small Kora oilfield, believed to have been sourced from the Laurel Formation.The Black Rocks Prospect, in King Sound, is being considered for the first 1986 exploration well. This represents a return to Devonian Pillara reefs, the traditional primary targets in EP 104. As a bonus, drape, accentuated by late collapse of the reefal core, has localized multiple Permo-Carboniferous structural closures, coincident with reefal closure.By comparison with the highly productive Swan Hills and Rainbow-Keg River reefs in Canada the Pillara and Worral carbonate cycles in EP 104 must have considerable potential.

Carnarvon Basin

There are four main Palaeozoic Basins in Western Australia; the Perth Basin (Permian only), the Carnarvon Basin (Ordovician-Permian), the Canning Basin (Ordovician-Permian) and the Bonaparte Basin (Cambrian-Permian).The Perth Basin is a proven petroleum province with commercially producing gas reserves from Permian strata in the Dongara, Woodada and Beharra Springs gas fields.The Palaeozoic of the Carnarvon Basin occurs in three main sub-basins, the Ashburton, Merlinleigh and Gascoyne Sub-basins. No commercial petroleum discoveries ahve been made in these basins.The Canning Basin can be divided into the southern Ordovician-Devonian province of the Willara and Kidson sub-basins and Wallal Embayment and Anketell Shelf, and the northern Devonian-Permian province of the Fitzroy and Gregory sub-basins. Commercial production from the Permo-Carboniferous Sundown, Lloyd, West Terrace, Boundary oilfields and from the Devonian Blina oilfield is present only in the Fitzroy sub-basins.The Bonaparte Basin contains Palaeozoic strata of Cambrian-Permian age but only the Devonian-Permian is considered prospective. Significant but currently non-producing gas discoveries have been made in the Permian of the Petrel and Tern offshore gas fields.Based on the current limited well control, the Palaeozoic basins of Western Australia contain excellent marine and non marine clastic reservoirs together with potential Upper Devonian and Lower Carboniferous reefs. The dominantly marine nature of the Palaeozoic provides thick marine shale seals for these reservoirs. Source rock data is very sparse but indicates excellent gas prone source rocks in the Early Permian and excellent—good oil prone source rocks in the Early Ordovician, Late Devonian, Early Carboniferous and Late Permian.Many large structures are present in these Palaeozoic basins. However, most of the existing wells were drilled either off structure due to insufficient and poor quality seismic or on structures formed during the Mesozoic which postdated primary hydrocarbon migration from the Palaeozoic source rocks.With modern seismic acquisition and processing techniques together with a better understanding of the stratigraphy, structural development and hydrocarbon migration, the Palaeozoic basins of Western Australia provide the explorer with a variety of high risk, high potential plays without the intense bidding competition currently present along the North West Shelf of Australia.
