Historically, sedimentological interpretations of the Kingia Sandstone in the northern Perth Basin have relied heavily upon conventional sedimentary facies analysis of a limited dataset integrating core with well-log data. This paper however provides...

Petroleum exploration expenditure increased both offshore and onshore compared to 2023 numbers, however this does not equate to a commensurate increase in activity. Onshore jurisdictions dominate the exploration and appraisal activities. In total 82 ...

Diagenesis comprise all the physical, chemical, and biological modifications underwent by a sediment, after its initial deposition, during and after lithification but before reaching pressures and temperatures proper of metamorphism. Burial diagenesi...

Geopolitical uncertainty continued in 2024 with continuation of the war in Ukraine, Israeli actions in the Gaza strip, tension between China and several neighbouring countries, and the impending election in the United States of America. Despite this,...

The Cretaceous Blackhawk Formation which crops out in the Book Cliffs of eastern Utah (USA) provides over 150 km of continuous exposures through a prograding clastic wedge. Since the 1980’s these outcrops have been central to the development of seq...

Geological analogues provide critical information to benchmark predictions across full cycle exploration and development projects. They seed ideas to recognise new plays and prospect opportunities to deliver the next cycle of discoveries. Since 2000 ...

The sediment provenance of Early Permian reservoirs (‘Kingia’ and High Cliff sandstones) of the onshore North Perth Basin is poorly understood. Bulk rock inorganic geochemistry, detrital zircon geochronology and heavy mineral data have been used ...

Monitoring of CO2 movement is a vital part of project execution, stakeholder engagement, and social licence to operate in CCUS projects. Monitoring obligations are challenging because the injected fluid is of negligible commercial value compared to h...

Monitoring and verification is one of the most distinctive aspects of CCS, but it is also one where there can be confusion about the nature and purpose of the activity. Any technical project will have methods for “monitoring and verifying”, but t...

Like any oil and gas operation, CCS projects need to assess environmental impacts, including potential impacts on groundwater. The identification of potential leakage pathways and approximation of leakage rates are a critical part of the site selecti...

There is a broad spectrum of expertise and skills required to develop and operate a CCS site. Two aspects that seem to be far removed from geoscience and engineering are these: social licence and regulation. However, both aspects are critical to de...

For the successful implementation and regulation of CO2 geological storage operations, it is important to establish a reliable definition, classification, and estimation of storage resources. For this purpose, the Society of Petroleum Engineers (SPE...

The practice of reservoir engineering and simulation in CCS begins with the standard physics of multiphase flow in porous media, but with CO2-specific properties to be represented, especially the solubility of CO2 in brine and the matching changes in...

In the second talk of the CCS Knowledge Transfer Series, we will discuss the physics and thermodynamics of CO2 flow in relation to CCS. We will highlight key differences, in terms of phase behaviour, between CO2 and other fluids more typically encoun...

The goal for carbon dioxide storage site selection and characterisation is to find a suitable location where an effective reservoir exists, matched to a CO2 source in both volume and injection rate. To ensure the CO2 is safely contained, the relative...
