dc.description.abstractTo unravel the geologic sequence of events leading to the current configuration of Jurassic sediments of the Poseidon and Crown gas fields, Browse Basin, North West Shelf (NWS), Australia, a multi-variate, fully integrated workflow was developed. Basins undergoing extensional tectonics are often associated with igneous intrusions, volcanic tuffs, or basalt flows, these high amplitude features can resemble gas-filled sandstones or carbonate reefs in reflection seismic data. Basaltic intrusions are present throughout the Mid-Late Jurassic interval that contains reservoir-quality sandstones in the study area. This work will complement reservoir characterization studies required to support multi- trillion cubic feet (tcf.) of liquified natural gas (LNG) exports and associated carbon capture projects on the NWS. The study outlines the steps in workflow creation and evaluation of effectiveness. A seismic-stratigraphic framework was built to understand the tectonic influence on Jurassic strata. Within the framework, a multi-attribute, hierarchical seismic facies classification process, correlated to the seismic signature of wellbore lithologies, defines Seismic Cluster Facies (SCF). These were used in interpreting paleogeography and major geologic event timing.
