Summary by Dr Fiona Burns

On  Tuesday 10th June, DEMIRES (in collaboration with PESA WA and  CCUSNA) organised a core workshop entitled  “Perth Basin from a CCS Perspective” which was  presented by Julie Cass and Dr Arthur Mory. We spent a day at the Perth Core Library considering how our collection of cores helps us to understand CCS targets in the Perth Basin. We also delved into the importance of characterising seals, the influence of reservoir heterogeneity vs homogeneity and how diagenesis impacts pore geometry.

On 20th February the WA branch lunch was held at the Hilton. The topic was “Natural Hydrogen in Western Australia” by Leon Normore, Geological Survey and Resource Strategy Division, Department of Energy, Mines, Industry Regulation and Safety, Government of Western Australia.

Leon provided an up-to-date summary of recent studies in Australia on hydrogen in natural gas samples in both sedimentary basins and cratonic settings and also discussed multiple abiogenic sources for natural hydrogen.

He summarised GSWA studies of open file data which focused on historical occurrences of hydrogen within the onshore sedimentary basins with petroleum wells the primary data source in Canning Basin, Perth Basin and Southern Carnarvon Basin well.
