Slide 15: Summary
Summary Recent appraisal drilling within West Erregulla including acquisition of full diameter core has given a greater understanding of the Kingia Sandstone in the Dandaragan Trough. The initial phase of tidal depositional environment allowed for the mechanism of initial clay coating that in a
