Monitoring of CO2 storage in a depleted natural gas reservoir: Gas geochemistry from the CO2CRC Otway Project, Australia

The CO2CRC Otway Project in southwestern Victoria, Australia has injected over 17 months 65 445 tonnes of a mixed carbon dioxide-methane fluid into the water leg of a depleted natural gas reservoir at a depth of approximately 2km. Pressurized sub-surface fluids were collected from the Naylor-1 observation well using a tri-level U-tube sampling system located near the crest of the fault-bounded anticline trap, 300 metres up-dip of the CRC-1 gas injection well. Relative to the pre-injection gas-water contact (GWC), only the shallowest U-tube initially accessed the residual methane gas cap. The pre-injection gas cap at Naylor-1 contains CO2 at 1.5 mol% compared to 75.4 mol% for the injected gas from the Buttress-1 supply well and its CO2 is depleted in 13C by 4.5%0 VPDB compared to the injected supercritical CO2. Additional assurance of the arrival of injected gas at the observation well is provided by the use of the added tracer compounds, CD4, Kr and SF6 in the injected gas stream.
Lessons learnt from the CO2CRC Otway Project have enabled us to better anticipate the challenges for rapid deployment of carbon dioxide in a commercial environment at much larger scales.

Sir Samuel Throssell Gravity Survey P201460 CSCBA267

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 Sir Samuel Throssell Gravity Survey P201460 CSCBA267 is a complete spherical cap Bouguer anomaly grid for the Sir Samuel Throssell Gravity Survey (P201460). This gravity survey was acquired under the project No. 201460 for the geological survey of WA. The grid has a cell size of 0.00477 degrees (approximately 499m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 11659 gravity stations were acquired to produce this grid.

Nabberu (North), WA, 1996 (P632), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data 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.
 These line dataset from the Nabberu (North), WA, 1996 survey were acquired in 1996 by the WA Government, and consisted of 24400 line-kilometres of data at 400m line spacing and 80m 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.

Total Magnetic Intensity (TMI) Grid of Australia with Variable Reduction to Pole (VRTP) 2019 - seventh edition

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. A variable reduction to Pole is aimed at locating magnetic anomalies exactly above their source bodies and without any distortion. The 2019 Total magnetic Intensity (TMI) grid of Australia with variable reduction to pole (VRTP) has a grid cell size of ~3 seconds of arc (approximately 80 m). This grid only includes airborne-derived TMI data for onshore and near-offshore continental areas. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date of January 2005 and elevation 300 m.

An Assessment of the Impact of the 34th International Geological Congress (IGC) on Australia

The International Geological Congress (IGC) represents a unique global meeting of geoscientists. Being selected to host the IGC is a strongly competitive process and the planning, organisation, administration and implementation of the congress require a significant national scale investment of resources. However, in focussing the attention of geoscientists from around the globe onto the host nation, the IGC also has the potential to produce extensive benefits at a range of scales; from the national scale, through to the organisational scale, and down to the personal level. The aim of the present study was to investigate the impacts of the 34th International Geological Congress from several different perspectives in an attempt to capture the impacts at these different scales.

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

Crustal structure of north Queensland from gravity anomalies

The interpretation of a reconnaissance gravity survey of north Queensland has shown that the area is composed of normal continental crust approximately 40 km thick, and is consistent with relief at the Moho of approximately 7 km. The parameters required for three-dimensional crustal gravity modelling, crustal thickness and density contrast across the Moho, were derived from available crustal seismic refraction experiments, together with analyses of correlations of crustal parameters on a worldwide basis. There are no large departures from isostatic equilibrium in the area. The southeastern part of the area is isostatically compensated and the crustal thickness reaches 43 km. The Mount Isa Block is not isostatically compensated and coincides with an area of thin (38 km) crust. This area is stable and, because of its size, is unlikely to achieve local isostatic equilibrium. The Cape York area has not reached isostatic equilibrium. The gravity anomaly pattern suggests that this area may have approached equilibrium progressively, with those parts of the area farthest from the centre of the Tasman Geosyncline having the smallest departure from isostatic equilibrium. This agrees with the history of development of the northern part of the Tasman Geosyncline, which youngs to the north and east. The Palmerville Fault is a major surface structure, but has no gravity effect originating at Moho depths, and hence may be only an upper crustal feature. The Coen Inlier also has little or no influence on the regional Bouguer anomalies, and is therefore probably a shallow crustal feature, of less significance than its surface outcrop suggests. The Cape York-Oriomo Ridge, however, has little surface expression, but is shown by the gravity data to be a major feature of the crust.

Progress towards deep coring of the Lord Howe Rise, northern Zealandia: a guide to the future of IODP riser drilling

Much has been achieved in 50 years of DSDP, ODP and IODP. However, to date deep riser drilling has played a relatively small role in IODP and its predecessors, albeit a role with considerable impact, especially in the understanding of subduction zone processes gained from CHIKYU drilling into the Japan forearc. More frequent deep riser scientific drilling is arguably a goal for the next 50 years of IODP. Geoscience Australia and JAMSTEC first discussed CHIKYU riser drilling on the remote Lord Howe Rise (LHR) continental ribbon, east of Australia, a decade ago. The resulting decade-long collaboration recognised the importance of the LHR in addressing globally-relevant scientific questions in Cretaceous tectonics and paleoclimate, as well as the limits to life on Earth. A proposal for deep riser drilling on the LHR was approved by IODP in early 2017. Subsequent planning for this ambitious expedition exemplifies the unique challenges faced by scientific riser drilling under IODP. These challenges include a need for comprehensive site surveys that allow a thorough assessment of geohazards, collection of baseline data to support environmental permitting, planning logistical support for remote, long-duration drilling operations, and securing funding for a high-cost expedition. This presentation will provide an overview of the efforts by JAMSTEC, Geoscience Australia and a diverse team of international proponents in delivering new data from the LHR extended continental ribbon that ultimately place IODP on the verge of ground-breaking scientific riser drilling in a remote part of northern Zealandia.
