Northern Houtman Sub-basin in the spotlight

The Houtman Sub-basin is the largest depocentre in the offshore Perth Basin and is almost 700 km long and up to 150 km wide. The Houtman Sub-basin and the adjacent part of the Abrolhos Sub-basin have been explored for hydrocarbons since the 1970's. Discovery of oil at Cliff Head in 2001 sparked exploration activity in the early 2000's.

Lawn Hill Gravity Survey p201840 CSCBA267GUVD

Gravity data measure small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This Lawn Hill Gravity Survey p201840 CSCBA267GUVD is the first vertical derivative of the complete spherical cap Bouguer anomaly grid for the Lawn Hill Gravity Survey 2018 (P201840). This gravity survey was acquired under the project No. 201840 for the geological survey of QLD. The grid has a cell size of 0.00185 degrees (approximately 200m). A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.  A total of 7231 gravity stations at 1000m spacing were acquired to produce this grid.

Microbial assemblage and paleoenvironmental reconstruction of the 1.4 Ga Velkerri Formation, McArthur Basin, northern Australia

The ca. 1.4 billion years (Ga) old Roper Group of the McArthur Basin, northern Australia, is one of the most extensive Proterozoic hydrocarbon-bearing basins deposited in a large epeiric sea known as the Roper Seaway. Black shales from the Velkerri Formation were deposited in a deep water shoaling sequence and are well preserved in the Altree 2 drillcore in the Beetaloo Sub-basin. These shales were analysed to determine their organic geochemical (biomarker) signatures which were used to interpret the microbial diversity and palaeoenvironment of the Roper Seaway. The results were integrated with published inorganic geochemistry and microfossil distributions.
The indigenous hydrocarbon biomarker assemblages describe a water column dominated by bacteria with large scale heterotrophic reworking of the organic matter in the water column or bottom sediment. Evidence for microbial reworking includes a large unresolved complex mixture (UCM) and high ratios of monomethyl alkanes relative to n-alkanes—features characteristic of indigenous Proterozoic bitumen. Steranes, biomarkers for single-celled and multicellular eukaryotes, were below detection limits in all extracts analysed, despite eukaryotic microfossils having been previously identified in the Roper Group. These data suggest that eukaryotes, while present in the Roper Seaway, were ecologically restricted and contributed little to the net biomass. The combination of increased dibenzothiophene in the middle Velkerri Formation and low concentrations of 2,3,6-trimethyl aryl isoprenoids throughout the Velkerri Formation suggest that the water column at the time of deposition was transiently euxinic. As a comparison we reanalysed extracts from the 1.64 Ga Barney Creek Formation of the McArthur Basin. The biomarker assemblages differ between the Velkerri and Barney Creek Formations between is a biomarkers and water column chemistry, demonstrating that the microbial environments and water column geochemistry were variable in the Proterozoic.

A Stratigraphic Reconstruction of Bulk Volatile Chemistry from Fluid Inclusions in: Putamurdie 1

Exploring for the Future (EFTF) was an Australian Government program led by Geoscience Australia (GA), in partnership with state and Northern Territory governments. The EFTF program (2016-2024) aimed to drive industry investment in resource exploration in frontier regions of onshore Australia by providing new precompetitive data and information about their energy, mineral and groundwater resource potential. 
Under the EFTF program, the Basin Inventory Project undertook a study of petroleum prospectivity of the onshore Eromanga Basin in Queensland and South Australia. Putamurdie 1 well in South Australia was selected based on the occurrence of gas and oil shows reported in the well completion report. Sampling of cuttings and cores was done at Geoscience Australia's Petroleum Data Repository in Canberra.
Geoscience Australia commissioned a fluid inclusion stratigraphy (FIS) study on the downhole samples.  Here, volatile components ostensibly trapped with fluid inclusions are released and analysed revealing the level of exposure of the well section to migrating fluids. Integration of thin section (TS) preparations reveal the extent of gas and fluid trapping within fluid inclusions while microthemometry (MT) gives an estimation of fluid inclusion trapping temperature.
For Putamurdie 1, FIS analysis was performed on 225 cuttings and 20 cores between 9.1 metres and 1952.5 metres base depth, together with 16 samples prepared for TS and 2 samples for MT. To support this study, lithostratigraphic tops were compiled by Geoscience Australia. The results of the study are found in the accompanying documents.

Delhi-Santos Gidgealpa No. 1 Well South Australia Of Delhi Australian Petroleum Ltd And Santos Limited

Delhi-Santos Gidgealpa No. 1 Well was drilled in the north-eastern corner of South Australia by Delhi Australian Petroleum Ltd, as operator, and Santos Limited. The well is 60 miles south-west of Innamincka No. 1 and 50 miles west-north-west of Dullingari No. 1. 
Gidgealpa No. 1 was spudded on 28th August, 1963, reached a total depth of 13,114 feet on 27th November, 1963, and was completed as a water well flowing from the Mooga Sandstone on 6th December, 1963. A National 80-B rig, owned and operated by Drilling Contractors (Australia) Pty Ltd, was used to drill the well.
Gidgealpa No. 1 was drilled as an off-structure well on the flank of a prominent closed anticline. The Mesozoic sequence was the thickest yet encountered in wells in the western part of the Great Artesian Basin, and very similar to that found in Innamincka No. 1. The overall lithology of the Permian in Gidgealpa No. 1 resembles that in Dullingari No. 1 although detailed correlation is not possible. Below the regional angular unconformity at the base of the Permian, a thick sequence of Cambrian marine carbonates and tuffaceous sediments was penetrated. This was the first encounter of Cambrian rocks in the subsurface of the Great Artesian Basin.
More hydrocarbon shows were encountered in the Permian sequence in this well than in any other drilled to date in this region. Unfortunately the sandstones exhibited very low porosity. A deep zone of porous dolomite, some 400 feet thick, was also discovered in the Middle Cambrian, and on test, flowed very gassy saltwater. Thus Delhi-Santos Gidgealpa No. I, in addition to providing much new geological information, gave most encouraging indications that, under favourable conditions, the Permian and the newly discovered Middle Cambrian dolomite could produce hydrocarbons.
The off-structure drilling operation at Delhi-Santos Gidgealpa No. 1 was subsidized under the Petroleum Search Subsidy Act 1959-1961, from surface to total depth.

Geoscience Australia Marine Survey SS06/2006 Post-Survey Report: Natural Hydrocarbon Seepage Survey on the Central North West Shelf

The petroleum potential of the central North West Shelf, encompassing the Offshore Canning and Roebuck basins, is currently considered to be poor compared to other North West Shelf basins, due to unsuccessful exploration in the past (13 dry wells drilled during 1970-1984) and the perceived absence of a prolific source rock.
In order to improve the understanding of the petroleum prospectivity of the central North West Shelf, Geoscience Australia undertook a natural hydrocarbon seepage survey of the area. The aim of the survey was to identify any sites of natural hydrocarbon seepage, which would provide direct evidence for an active petroleum system within the sub-surface. A secondary objective was to contribute to the understanding of the modern sedimentary and oceanographic processes influencing this part of the shelf, and the nature of the benthic habitats.
This report presents a summary of the results of Geoscience Australia's RV Southern Surveyor Survey SS06/2006 on the central North West Shelf, undertaken 29 May to 22 June 2006. More than 70 Gb of geophysical and oceanographic data and 140 sediment, water and video samples were acquired during the survey.

The origin and evolution of the Earth's continental crust

The present upper crustal composition of the Earth is attributed largely to intracrustal differentiation, resulting in the production of K-rich granites. The crust grows episodically and it is concluded that at least 60 per cent of it was emplaced by the late Archaean (ca 2.7 Ae).  Archaean tonalites and trondhjemites resulted from slab melting of young hot oceanic crust. In contrast, most subduction-related rocks, now the main contributors to crustal growth, are derived from the mantle wedge above subduction zones. The contrast between the processes responsible for Archaean and post-Archaean crustal growth is attributed to faster subduction of younger (hotter) oceanic crust in the Archaean (ultimately due to higher heat flow) compared with subduction of older cooler oceanic crust in more recent times. The terrestrial continental crust appears to be unique compared to crusts on other planets and satellites in the solar system, ultimately, a consequence of the presence of water on Earth.
