FOREWORD

Under the Petroleum Search Subsidy Act 1959-1961, agreements relating tosubsidized operations provide that the information obtained may be IMblished by the Common­wealth Government six months after the completion of field work.

The growth of the exploration effort has greatly increased the number ofsubsidized projects and this increase has led todelays in publishing the results of operations.

The detailed results of subsidized operations may be examined at the offices ofthe Bureau of Mineral Resources in Canberra and Melbourne (after the agreed period) andcopies of the reports may be IMrchased.

In order to make the main results of operations available early, short summariesare being prepared for IMblication. These wiU be grouped by area and date of completion asfar as practicable. Drilling projects and geophysical projects will be grouped separately.In due course, full reports will be IMblished concerning those operations which have producedthe more important new data.

This PUblication contains summaries of data and results of two drilling operationsundertaken in the Surat Basin, Queensland: Union-Kern-A.O.G. Middle Creek No. 1, andUnion-Kern-A.O.G. Southwood No. 1. The information has been abstracted by the PetroleumExploration Branch of the Bureau of Mineral Resources from well completion reportsfurnished by Union Oil Development Corporation.

UNION-KERN-A"O.G. MIDDLE CREEK NO. 1

SUMMARY OF DATA AND RESULTS*

SUMMARY

Union-Kern-A.O.G. Middle Creek No. 1 was the fourth wildcat well drilled byUnion Oil Development Corporation in the south-eastern part of the Surat Basin. The well,located approximately eight miles north-north-east of Union-Kern-A.O.G. Moonie No. 1,was drilled by Mines Administration Pty Limited for Union Oil Development Corporation to atotal depth of 6126 feet. Drilling commenced on 19th May, 1962 and was completed on 8thJune, 1962. A full programme of logging, testing, and coring was undertaken.

The well penetrated 118 feet of Quaternary-Tertiary sandstone and shale;2153 feet of Lower Cretaceous Roma Formation; 1053 feet of Lower Cretaceous-JurassicBlythesdale Formation; 1045 feet of Jurassic Walloon Formation; 639 feet of Hutton Sandstone;540 feet of Evergreen Shale; and 352 feet of Jurassic-Triassic Precipice Sandstone. Belowthe unconformity at the base of the Precipice Sandstone at 5912 feet, the test entered volcanicconglomerates and siliceous sandstones of the Permo-Carboniferous Kuttung Formation inwhich the well bottomed at 6126 feet.

No drill stem test was carried out in tile Precipice Sandstone but high resistivityon the electric log suggests freshwater saturation. A 60-minute open hole formation testwas made of a sandstone interval (5240-5263 feet) witilin the Evergreen Shale. A net rise of4790 feet of slightly gassy water (37 gr;/gal.) was recovered on the test. In the absence of anysignificant shows, cement plugs were set and the well was abandoned on 10til June, 1962.

The test drilling operation at Union-Kern-A.O.G. Middle Creek No. 1 wassubsidized under tile Petroleum Search Subsidy Act 1959-1961, from surface to total depth.

Roma Formation (Lower Cretaceous): 130 to 2283 feet (2153 feet)

Interbedded, grey, fine to coarse-grained, quartzose sandstone, grey siltstoneand dark grey carbonaceous shale. Coal seams occur in the interval 615 to 915 feet.

Blythesdale Formation (Lower Cretaceous-Jurassic): 2283 to 3336 feet (1053 feet)

Mainly light grey, coarse-grained, quartzose sandstone with thin interbeds ofgrey carbonaceous. shale.

Walloon Formation (Jurassic): 3336 to 4381 feet (1045 feet)

Interbedded grey, carbonaceous shale, siltstone and coal seams.

Hutton Sandstone (Jurassic): 4381 to 5020 feet (639 feet)

Interbedded, light grey, fine-grained. quartzose sandstone and siltstone withminor shale.

4

Evergreen Shale (Jurassic): 5020 to 5560 feet (540 feet)

Thinly bedded sequence of grey to brown siltstone and shale with some coalseams. Light grey, fine to coarse-grained, quartzose sandstone is present in theinterval 5232 to 5262 feet.

Precipice Sandstone (Jurassic - Triassic): 5560 to 5912 feet (352 feet)'

Mainly white to light grey, fine to very coarse-grained, quartzose sandstone.

Kuttung Formation (Permo-Carboniferous): 5912 to 6126 (T.D.) (214 feet +)

The interval 5912 to 6075 feet consists of white to greenish-grey, fine tocoarse-grained, lithic sandstones. The interval 6075 to 6126 feet (T.D.) consists ofsilicified conglomerate comprising pebbles and cobbles of greenish, orange, andIllrple volcanic rocks.

Structure

The Middle Creek prospect is a south-west plunging Mesozoic fold separatedby a saddle from the domal closure of the Moonie Field. The plunge of the feature is fairlygentle averaging approximately 70 feet per mile. The fold has fairly symmetrical flanksthat have a dip to the north-west and south-east of approximately 320 feet per mile. ThisMesozoic fold unconformably overlies a truncated and faulted sequence of rocks ranging inage from Carboniferous to Lower Triassic. The fold axis is parallel to a major north-eaststriking reverse fault in the underlying Palaeozoic beds.

Oil and Gas Indications and Potential

Cores from the Precipice Sandstone (5560 to 5912 feet), the primary target inMiddle Creek No. 1 Well, were wet and showed no fluorescence, odour, stain, or cut. Porositiesin the sandstone at the top of the formation (5560 to 5619 feet) range from 4.3% to 18.7% andpermeabilities from 0 to 32 md. Porosities in the lower massive sandstone of the formation(5705 to 5912 feet) vary from 7.4% to 20.0% and permeabilities from 6 to 740 md.

An open hole formation test of the interval 5240 to 5263 feet recovered a net riseof 4790 feet of slightly gassy water (37 gr./gal.) from a sandstone within the Evergreen Shale.Porosities in this sandstone average 20% and permeabilities range from 557 to 1795 md.

UNION-KERN-A.O.G. SOUTHWOOD NO. 1

SUMMARY OF DATA AND RESULTS*

SUMMARY

Union-Kern-A.O.G. Southwood No. 1 Well, located approximately six milessouth-west of Middle Creek No. 1 and about 15 miles south of Union-Kern-A.O.G. CabawinNo. 1, was drilled by Oil Drilling and Exploration Limited for Union Oil Development Corpor­ation to a total depth of 10,897 feet. Drilling commenced on 11th March, 1963 and was com­pleted on 15th May, 1963. A programme of logging and coring was undertaken.

Southwood No. 1 was s]:Udded in the Lower Cretaceous Roma Formation. Thewell then penetrated the Lower Cretaceous-Jurassic Blythesdale Formation at 1542 feet;the Jurassic Walloon Formation at 4065 feet; the Hutton Sandstone at 5118 feet; the EvergreenShale at 5850 feet; the Jurassic-Triassic Precipice Sandstone at 6370 feet; the TriassicCabawin Formation, unconformable beneath the Precipice Sandstone, at 6825 feet; the PermianKianga Formation at 7375 feet; and the Permian Back Creek Formation at 7995 feet. Becauseof drilling difficulties the hole was abandoned at 10,897 feet in the Back Creek Formation.

The well was drilled to test the hydrocarbon potential of a closed domal structurein Permian sediments in an area approximately three miles north-west of the Moonie Field.At the location of Southwood No. I, the "11' Horizon structure map which represents thestructure on the approximate top of the Permian Kianga Formation, the producing sectionof Cabawin No. I, indicates a faulted dome with 800 feet of vertical closure over an area ofabout 15 square miles. This closure is only one of a series of faulted domes parallelling theMoonie Field.

The Precipice Sandstone included potential reservoir beds but only a trace ofblue fluorescence was noted. White fluorescence, gas shows, and oil odours were recordedfrom the Cabawin, Kianga, and Back Creek Formations but all three formations wereimpermeable. The hole was abandoned as dry.

The stratigraphic drilling operation at Union-Kern-A.O.G. Southwood No. 1was subsidized under the Petroleum Search Subsidy Act 1959-1961, from 6400 feet to totaldepth.

Detailed:

Roma Formation (Lower Cretaceous): 1300 to 1542 feet (242 feet +)

Interbedded, shallow water marine siltstone, sandstone, and shale with minortraces of coal. The siltstone and shale are grey, soft, and carbonaceous.

Blythesdale Formation (Lower Cretaceous-Jurassic): 1542 to 4065 feet (2523 feet)

From 1542 to 2858 feet, the sequence is transitional from the Roma Formationto a predominantly arenaceous section, The latter, from 2858 to 3415 feet, consistsof coarse-grained, porous, quartzose sandstone. The lowest part of the formation,from 3415 to 4065 feet, consists of interbedded grey to brown, tuffaceous, carbonaceousshale and fine to medium-grained, light grey, quartzose sandstone.

Walloon Formation (Jurassic): 4065 to 5118 feet (1053 feet)

A fresh water sequence of siltstone, shale, and coal, with traces of sandstone.The siltstone and shale are light to dark brown, and carbonaceous.

Hutton Sandstone (Jurassic): 5118 to 5850 feet (732 feet)

Light grey, fine to coarse-grained, quartzose porous sandstone with interbeddedsiltstone and shale.

Evergreen Shale (Jurassic): 5850 to 6370 feet (520 feet)

Interbedded, tan to grey, carbonaceous siltstone, and dark grey to dark brown,carbonaceous shale with minor light grey to green, fine to medium-grained, quartzosesandstone intercalations.

14

Precipice Sandstone (Jurassic-Triassic): 6370 to 6825 feet (455 feet)

Quartzose, grey to green, porous, permeable sandstone with shale and siltstonein the upper part and 50 feet of conglomerate at the base.

Cabawin Formation (Triassic): 6825 to 7375 feet (550 feet)

Green and grey-green, tuffaceous, granule-pebble conglomerate and conglomer­atic sandstone with minor interbeds of reddish-brown siltstone and shale.

Kianga Formation (Permian): 7375 to 7995 feet (620 feet)

Interbedded coal and tuff with minor tuffaceous sandstone, siltstone, and shale.The contact with thp. underlying Back Creek Formation is gradational.

Back Creek Formation (Permian): 7995 to 10,897 feet (2902 feet +)

Marine siltstone and shale with minor tuffaceous sandstone and conglomerate.Coal seams occur in the upper part of the sequence. Marine fossils are abundantthroughout.

Structure

The structure is a faulted dome, located by seismic survey, having a verticalclosure of 800 feet over an area of about 15 square miles in Permian sediments. Thesesediments occur in a complexly faulted belt to the north-west of the Moonie Field.

Oil and Gas Indications and Potential

NO'significant shows were logged in the section above the Cabawin Form­ation, except for a trace of blue fluorescence at the top of the major sandstone developmentof the Precipice Sandstone. Porosities in a portion of the upper sandstone unit of thePrecipice between 6403 - 6432 feet ranged from 5.3% to 18.6% and permeabilities from 0 to225 md; porosities in the top of the major Precipice sandstone development between 6521 ­6541 feet ranged from 7.5% to 20.1% and permeabilities from 0 to 219 md. Microlog indic­ated that the best continuous reservoir section in the Precipice Sandstone was between 6626 ­6764 feet.

Although traces of white fluorescence and methane gas shows were recorded in theCabawin Formation, the sandstones and conglomerates of the formation are impermeable andshow no reservoir potential.

The Permian Kianga and Back Creek Formations were the major targets of theSouthwood test. Methane gas and traces to strong shows of bluish-white fluorescence werelogged throughout the Kianga; however, the entire section was impermeable. Cores within theBack Creek Formation bled traces of gas and had a fleeting oil odour on fresh breaks. Therewere traces of white fluorescence and methane gas shows with traces of heavier hydrocarbonin the formation; however, as with the Kianga, the Back Creek Formation was impermeablewith no reservoir potential.
