10th of June , 9:00 – 1600 Carlisle Core Library

Perth Basin from a CCS Perspective

Spend a day at the Perth Core Library considering how our collection of cores help us to understand CCS targets in the Perth Basin. We will delve into the importance of characterising seals, the influence of reservoir heterogeneity vs homogeneity and how diagenesis impacts pore geometry.

The Cattamarra Coal Measures ranks highly as a saline aquifer CCS reservoir target as it has excellent net-to-gross and reservoir quality over thick intervals. The fluvio-deltaic depositional environment of this unit provides for significant heterogeneity to promote lateral migration of the injected plume. Diagenesis impacts reservoir quality as a function of depth of burial and reservoir temperature. These impacts will be demonstrated with a suite of cores from various structural settings in the basin.

The Dongara Sandstone has attracted attention as a potential CCS reservoir target in depleted fields. Due to the homogeneous nature of the shoreface facies, this may be the best interval to study the impact of hydrocarbon charge on diagenesis and porosity preservation.

Cores of sealing lithologies are rare but provide important constraints when characterising a CCS storage formation. A suite of cores from the Kockatea Shale and Hovea Member will be investigated to understand variations in facies and the impact of diagenesis on geomechanical properties.

The workshop will be led by Julie Cass and Arthur Mory (GSWA) with assistance from Simon Molyneux (Molyneux Advisors) and Jeremy Prosser (Task Fronterra). Simon will show how cuttings can be utilised to investigate these same reservoir quality controls and Jeremy will illustrate how image log data compliments analyses of core and cuttings.
