A detailed marine reflection seismic survey was carried out by Western Geophysical Company of America, Party 87, for Phillips Australian Oil Company, Sunray DX Oil Company, Canadian Superior Oil (Aust.) pty Ltd, and Anacapa Corporation between 22 January and 24 April 1966. The survey covered 1505 line miles over the Papuan Basin, in the Gulf of Papua, within Oil Permits Nos 39 and 42, and Oil Licence No. 4 (see Fig. 1). The objective of the seismic survey was to obtain more detailed information on structures indicated by previous reconnaissance seismic work, with a view to determining drilling sites, and tor extend the reconnaissance in the area.

A.A.O. Winnathoola No. I, located approximately 8 miles north-west of A.A.O. Combarngo No. I, and 22 miles south-east of Roma in Queensland, was drilled by Mines Administration Pty Limited for Associated Australian Oilfields N.L., to a total depth of 5342 feet. Drilling commenced on 1st September, 1961 and was completed on 22nd September, 1961. A full programme of logging, testing, and coring was undertaken. The well penetrated 4919 feet of Mesozoic sediments, 207 feet of Permian sediments, and 216 feet of of sediments of (?) Devonian Timbury Hills Formation. Two drillstem tests were carried out. The first tested the interval 4521 to 4465 feet (basal Jurassic sands) for 120 minutes and yielded a flow of gas at the rate of 616 Mcf/D. The second tested the interval 5342 to 5035 feet (base of Permian) and yielded a trace of gas. The stratigraphic drilling operation at A.A.O. Winnathoola No. 1 was subsidized under the Petroleum Search Subsidy Act 1959 for the section below the Jurassic Injune Creek Beds to total depth.

This kit follows the Mt Todd Map Kit- An Introduction to Geological Maps. It is designed to extend students by showing them a more complex geological map as well as different ways geological information can be displayed. Finally, the kit will introduce students to the use of geophysics and how it can be used to help interpret the geology of an area. It is assumed that students will have used the Mt Todd Map kit prior to using this kit. This kit is therefore not as extensive in its explanations of the basic map information. Only those new areas or areas which are markedly different will be discussed.

Planet Warrinilla North No. 1 Well was located approximately 32 miles south of Rolleston, and about 16-1/2 miles north of Planet Warrinilla No. 1 Well. The site was determined from an analysis of seismic data and was located on a culmination on the northern plunge of the Warrinilla Anticline in the Bowen Basin. Based on seismic control near the top of the Ingelara Formation, this structure is believed to have 120 feet of closure and an areal extent of six square miles. Drilling operations at Warrinilla North No. 1 were carried out between 28th July and 8th October 1963, after which production casing was set and further testing was undertaken between 10th-25th October. A full programme of logging, testing, and coring was carried out. The well passed through the Triassic Rewan Formation, and Permian beds which included the Bandanna Formation, Mantuan Productus Bed, Catherine Sandstone, Ingelara Formation, Aldebaran Sandstone, and Cattle Creek Formation. The well bottomed in the preCattle Creek fresh water beds at a depth of 6879 feet, and was abandoned on 25th October 1963. A number of gas shows were encountered in the well and although none of these proved commercial, much information was gathered both from the drilling of the well and from the evaluation testing that followed. A total of 23 drillstem tests was run. However, four of these were misruns. A maximum gas recovery of 162 000 cubic feet per day was obtained from the Aldebaran Sandstone. The well was drilled by Delta Drilling Company using a National 55 rig. Technical control at the well site was provided by N.A. Meyers of Cundill, Meyers and Associates, mud logging by Core Laboratories, Inc., and electrical logging by Schlumberger Seaco Inc. The test drilling operation at Planet Warrinilla NorthNo. 1 was subsidized under the Petroleum search Subsidy Act 1959-1961, from surface to total depth.

These guidelines set out arrangements to ensure a uniform and consistent approach to administration of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 and the Petroleum (Submerged Lands) (Data Management) Regulations 2004, and the equivalent legislation in the States/NT. The Guidelines will assist industry in managing data submission requirements and for feedback. They will be modified as required in accordance with prevailing petroleum legislation and supporting regulations, and also with technology. Titleholders are encouraged to submit data in the manner described in the document. In the event of disagreement between these guidelines and current legislation or directions, the latter will prevail. For further information regarding these guidelines please contact: Eddie Resiak, Geoscience Australia, 02 6249 9289, eddie.resiak@ga.gov.au For feedback on these guidelines please contact: Andrew Barrett, Geoscience Australia, 02 6249 9440, andrew.barrett@ga.gov.au

A Mid Jurassic (late Callovian) suite of marine microplankton is present in the Elang Formation and its equivalents in the Timor Sea, offshore north-western Australia. It includes two genera, Voodooia and Woodinia and eleven species of dinoflagellate cysts which are described as new. The dinoflagellate cyst species are Ctenidodinium ancorum, Ctenidodinium fuscibasilarum, Ctenidodinium planocristatum, Durotrigia magna, Fusiformacysta terniana, Lithodinia protothymosa, Meiourogonyaulax penitabulata, Meiourogonyaulax viriosa, Voodooia tabulata, Woodinia pedis and Yalkalpodinium elangiana. A new acritarch species, Nummus apiculus, is also described. The dinoflagellate cyst genus Fusiformacysta is emended to stress the 3P nature of the archaeopyle and the presence of at least one, small anterior intercalary paraplate. The genera Lithodinia and Meiourogonyaulax are both maintained here, as the opercula are compound and simple respectively. Tabulodinium and its single species, T. senarium, are emended, in order to fully describe this intriguing species, the ornamentation of which is apparently destroyed by oxidation. The genus Yalkalpodium is emended to accommodate the new form Y. elangiana. All these new microplankton taxa have stratigraphical utility in the Wanaea digitata and Rigaudella aemula (interval) zones.
