Abstract:
Stratigraphic correlation in kilometres-thick Triassic fluvial successions of the Carnarvon Basin, Northwest Shelf (NWS), Australia, has traditionally been hindered by a lack of continuous seismic events, low biostratigraphic resolution and the practice of lithostratigraphically correlating sandstone in well logs in the subsurface that are commonly discontinuous. To overcome these challenges, Chevron Australia tested and integrated multiple stratigraphic techniques to create a unified, Triassic regional stratigraphic framework across the entire Carnarvon Basin. This was achieved by integrating environment of deposition interpretations from core with high resolution biostratigraphy, chemostratigraphy, magnetostratigraphy, sequence stratigraphy, seismic stratigraphy and seismic geomorphology across the basin.
