Abstract

The well folio package contains the combined data of 23 offshore wells in the northern Perth Basin, including the first published synthesis of data from fourteen new field wildcat wells drilled in this part of the basin since the Cliff Head 1 discovery (2001). Completed as part of the Australian Government's Offshore Energy Security Program, the well folio package will improve the assessment of petroleum prospectivity in the offshore Perth Basin. The well folio package consists of 23 composite well log plots, six well to well correlations and a new chronostratigraphic sequence framework and includes Geoscience Australia's revised Offshore Perth Basin Biozonation and Stratigraphy 2011 Chart 38 (Jones et al., 2011a). The well folio package summarises key stratigraphic, biostratigraphic and geochemical data and sequence interpretations for wells in the offshore northern Perth Basin from the Beagle and Turtle Dove ridges, Houtman and central Abrolhos sub-basins and the Wittecarra Terrace. Composite well log plots at 1:5000 scale summarise, in graphic form, the main stratigraphic features and hydrocarbon occurrences. The composite well logs also graphically summarise results from 120 new palynological samples and 244 new Rock-Eval pyrolysis/Total Organic Carbon (TOC), 85 new Vitrinite Reflectance (VR), 14 new FAMM maturity and compiled Grains with Oil Inclusions (GOITM) measurements. Compilations of new and open-file biostratigraphic and geochemical data are also included in digital spreadsheet formats. Data from the 23 offshore wells show that the main sedimentary succession in the offshore northern Perth Basin is Permian to Late Jurassic in age: two wells intersected a sandstone section of Late Cambrian to Early Ordovician age. Reviewed open-file biostratigraphic data, new biostratigraphic data and interpretations from these samples have been used in conjunction with well logs and lithological interpretations of cuttings, cores and side wall cores to define a new chronostratigraphic sequence framework for this part of the basin. Sequences and major maximum flooding surfaces are correlated between wells to show the spatial and temporal distribution of these sequences through the offshore northern Perth Basin.
