Applying petrophysics and rock property modelling to enhance play-based assessments of the geological storage potential for carbon dioxide: western Eromanga Basin case study

Identifying basin areas that are prospective for the geological storage of carbon dioxide (GSC) is essential to support Australia’s transition to a net-zero emissions energy future. Geoscience Australia has developed a play-based common risk segment (CRS) mapping approach to evaluate GSC prospectivity based on four geological risk elements: injectivity, storage effectiveness, containment and structural complexity. Various geological criteria are used to evaluate these risk elements using post-drill data/analysis, gross depositional environment (GDE) maps, rock property maps, and depth structure and isochore maps. Rock property maps form an essential component in defining the CRS’s for GSC prospectivity maps. This paper provides a case study from Geoscience Australia’s assessment of the GSC potential for the western Eromanga basin (WEB).&nbsp;&nbsp;
&nbsp;
Rock property maps are constructed in the Petrel Software Platform (©SLB). Inputs for these models include a 3D structural model incorporating 14 play intervals, GDE maps, and sub-surface rock properties derived from petrophysical analyses of wireline log data (such as volume of clay/shale, total and effective porosity, Timur-Coates permeability and apparent water salinity). Key outputs from the geological model include: permeability thickness ([kh] used to assess injectivity); effective porosity (used together with depth structure maps to assess storage effectiveness); and net seal thickness (used to assess containment). Results from the CRS mapping show the WEB has potential to support industrial-scale (>1 megatons per annum [Mtpa]) GSC projects using migration assisted storage (MAS) in structurally simple areas where there is favorable stacking of effective reservoirs overlain by impermeable seals.

A new lithostratigraphic framework for the Early Jurassic units in the Bundamba Group, Clarence-Moreton Basin, Queensland and New South Wales.

Recent detailed studies of key transects throughout the Clarence-Moreton Basin have shown that a revision of nomenclature is required for units in the Late Triassic to Early Jurassic Bundamba Group. Revision of the stratigraphic nomenclature and elimination of the existing confusion in names of units in the basin was considered an essential first step in understanding basin evolution and assessing petroleum potential.  We redefine the Marburg Formation as the Marburg Subgroup of the Bundamba Group and divide the Subgroup into two distinct lithostratigraphic units, the uniform sandstone of the Gatton Sandstone and the mixed sandstone and mudrocks of the younger Koukandowie Formation. The formations are upgraded existing members.  The Gatton Sandstone contains locally developed members along the western basin margin.  The Koreelah Conglomerate Member forms the base of the Gatton Sandstone where it overlaps basement rocks, and the Calamia Member of mixed shale, mudrocks and sandstone is a basal unit in the Gatton Sandstone in more basinward sections.  The Heifer Creek Sandstone Member is a prominent quartzose sandstone unit in the Koukandowie Formation along the western margin and central parts of the basin. The older mixed mudrocks and sandstone of the Ma Ma Creek Member of the Koukandowie Formation are mainly known from the northwest. This new nomenclature preserves the integrity of existing stratigraphic names and is applicable basin- wide. One new stratigraphic name, the Koreelah Conglomerate Member, is introduced.

The age of the diamond-bearing pipes and associated leucite lamproites of the West Kimberley region, Western Australia

New K-Ar and Rb-Sr ages obtained for 14 separate lamproite intrusions in the Fitzroy area of the West Kimberley region of Western Australia confirm the early Miocene ages previously  obtained for the Fitzroy lamproites. Similar (early Miocene) ages were obtained for the leucite lamproite intrusions and one of the newly discovered diamondiferous pipes of olivine  lamproite resembling kimberlite. This is consistent with their close spatial association in the  field and their petrologic and geochemical similarities. There is a small difference in age between the northernmost intrusions of the Ellendale area (20-22 Ma) and those further south in the Noonkanbah area (18-20 Ma). The early Miocene ages of the West Kimberley diamond pipes make these the youngest primary source of diamond yet found.

Robertson 1:250 000, R502 historical topographic map

The R502 series of maps has been replaced by the National Topographic Map Series (NTMS). The R502 series consists of 542 map sheets and covers Australia at a scale of 1:250,000. It was compiled from aerial photography, but only about one quarter of the series was contoured. The standard sheet size is 1 degree of latitude by 1.5 degrees of longitude. Transverse Mercator map projection and Clark 1858 datum were used. Coverage of the country was completed in 1968.

Merredin-Bruce Rock, WA, 1997 (P1064), radiometric line data, AWAGS levelled

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). 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 Merredin-Bruce Rock, WA, 1997 (P1064), radiometric line data, AWAGS levelled were acquired in 1997 by the WA Government, and consisted of 27533 line-kilometres of data at a line spacing between 150m and 200m, and 50m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Novel methods for near-surface hydrogeological feature enhancement from high-resolution airborne magnetic data

The delineation of near-surface (0-300 m) hydrostratigraphy and tectonic features is essential for successful characterisation of groundwater systems and subsequent hydrogeological modelling. While most remote sensing of such systems is commonly achieved using high-resolution airborne electromagnetic (AEM) data, validated by drilling data, and complemented by the use of terrain and multispectral data, and borehole and ground hydrogeophysics, it is shown that there is also a useful role for high-resolution magnetic survey data. Various filtering of gridded magnetic data, when image-enhanced and interrogated with other datasets, reveal features such as faults, dykes and other structures which may influence the distribution and movement of groundwater. 
One of the most useful enhancements of magnetic data is the tilt angle, which is derived from the arc tangent of ratio of the vertical and horizontal derivatives of the reduced to the pole magnetic data. As the tilt amplitudes are always between ±90° regardless of the magnetic derivative amplitudes, this processing method acts similarly to automatic gain control to highlight both strong and weak source responses. A useful application of this tilt angle is estimating relative depths of magnetic features. Additional data, if available, can be used to calibrate these depth estimates. Dip directions of source contacts can be estimated by using the attitudes of multiscale edges, derived from the maxima of total horizontal derivative data. Examples of the utility of high-resolution magnetic data, in its complementary role, are presented for two groundwater assessment project areas — the Menindee Lakes region in western NSW and the Keep River catchment in the Northern Territory.

A seismic investigation of the eastern margin of the Galilee Basin, Queensland

In 1976, four seismic reflection traverses were shot across, and close to, the eastern margin of the Galilee Basin to investigate the structure of the basins northeast margin with relevance to the extent of the Permian coal measures, and to investigate the relationships and extent of the underlying Devonian Adavale Basin and Devonian-Carboniferous Drummond Basin. The results show that the basins northeast margin is steep and faulted, and that there is only a narrow strip in which coal is likely to be found at easily mineable depths. About 30 km southwest of this margin, the sediments are undisturbed, with a southerly dip of about half a degree; here 2000 m of Galilee Basin sedimentary rocks overlie 700 m of Drummond Basin sediments - which extend further to the northwest than was previously thought. The eastern part of the Galilee Basin is underlain by the fluviatile sediments of the Drummond Basin. The more prospective Adavale Basin does not extend as far north as Jericho No. 1 exploration well. The Koburra Trough, along the northeast margin of the Galilee Basin, contains a thick sequence of Permo-Carboniferous sediments; results from the 1976 survey indicate that it could be bounded by large anticlinal or monoclinal structures which might provide petroleum traps; it is on this area that exploration should concentrate.
