Abstract:
Chevron has developed a method for merging, viewing, and interpreting multiple 3D seismic surveys in stratal slice domain. The products of this method are referred to as Regional Stratal Slice Volumes (RSSVs). Within the Northern Carnarvon Basin (NCB), NWS, Australia, local RSSVs have been built using a patchwork of 3D seismic data sets of various vintages and data quality covering an area of approximately 68,000 km2. RSSVs have been built within the Triassic post-rift and Jurassic-Cretaceous syn-rift and post rift intervals. The Triassic section is comprised of a 4 plus km-thick interval of alluvial to shallow-marine deposits of the Late Triassic Mungaroo/Brigadier Formations and Early Jurassic North Rankin Formation, whereas the younger Jurassic-Cretaceous succession is comprised of a tectonically influenced Jurassic interval overlain by syn-rift to post rift Barrow Group.
