    PESA WA: Technical lunch talk – 16 February

    Presented by Julie Cass, GSWA. The Ordovician interval cored in Olympic 1 is one of the best-documented cored intervals of the Nambeet Formation in the Canning Basin. Consequently, the Geological Survey of Western Australia (GSWA) entered into a collaborative core analysis agreement with the EP473 Joint Venture to acquire a suite of core plugs for stratigraphic and petroleum system testing and CO2 geosequestration evaluation.

    This presentation offers an integrated interpretation of petrophysical and petrographic data acquired at Olympic 1, assessing reservoir quality in the Ordovician and the impact of acoustic properties on seismic prospecting at the Meda unconformity. Volume of clay, porosity and saturation have been calculated from wireline logs to assist in the petrophysical evaluation and for comparison with x-ray diffraction, routine and special core analysis measurements.

    PESA WA Workshop: Salt Tectonics in Australian Sedimentary Basins

    PESA WA invites you to a 1 day workshop on Friday 23rd February, “Salt Tectonics in Australian Sedimentary Basins”, presented by instructor Chris Elders. Interest in salt deposits in sedimentary basins has increased dramatically in recent years because of its potential role as a seal for natural hydrogen and helium accumulations, and as a site for the storage hydrogen and other gases. Although salt is present in a number of Australian basins, there are relatively few studies that document the evolution of salt structures in the context of wider research that has developed rapidly over the past 20 years. In this workshop we will examine current thinking on the evolution of salt structures and apply these concepts to examples of salt structures from the Petrel, Vulcan, Canning, Officer and Amadeus basins. Participants are encouraged to bring examples of their own favourite salt structures for part of the discussion.
