Browse Basin Cretaceous and Cenozoic surface grids
<p>Geoscience Australia completed a regional assessment of the geological carbon dioxide (CO2) storage potential and petroleum prospectivity of the Browse Basin, offshore northwest Australia. This dual-purpose basin analysis study provided a new understanding of the basin’s Cretaceous succession based on new information regarding basin evolution, sequence stratigraphy, structural architecture and petroleum systems. The basin’s tectonostratigraphic framework was updated, and the integration of revised and recalibrated biostratigraphic data with well log and seismic interpretations has enabled an improved understanding of variations in depositional facies and the spatial distribution of reservoir, seal, and source rock sections. The outputs include models and maps of environments of deposition, play fairways, common risk element maps for regional-scale assessment of CO2 storage potential and petroleum systems model (Abbott et al., 2016; Edwards et al., 2015, 2016; Grosjean et al., 2015; Palu et al., 2017a and b; Rollet et al., 2016b, 2017a,b, 2018).<p>
<p>This data pack includes 12 Cretaceous and Cenozoic horizons, and the regional fault maps produced from this study. This interpretation is based on data from 60 wells (Table 1) and 26 regional 2D and 3D seismic reflection surveys (Table 2) (Rollet et al., 2016a). Surfaces were converted from TWT to depth and integrated in a 3D geological model as input into a petroleum systems model (Palu et al., 2017a, b).
<p>Data layers include:
<p>12 regional depth surface grids and arcmap files generated for key Cretaceous and Cenozoic horizons (Figure 1; Table 3): K10.0_SB (late Tithonian), K20.0_SB (Valanginian), K30.0_SB (Late Hauterivian), K40.0_SB (Aptian), K50.0_SB (Late Cenomanian), K60.0_SB (Early Campanian), K65.0_SB (Maastrichtian), T10.0_SB (Base Cenozoic), T24.0_SB (Ypresian), T30.0_SB (Rupelian), T33.0_SB (Aquitanian) and water bottom based on bathymetry after Whiteway (2009),
<p>2 fault population shapefiles (Figure 2): polygon envelop of shallow faults that formed during the Cenozoic collision between Australia and Asia, and horizon fault boundaries of deep regional faults that were formed through the Permian to Cretaceous.

Data were compiled from horizon interpretation of open file marine seismic surveys and well markers interpretation. Horizon xyz data were exported from GeoFrame interpretation software, depth converted in DUG (Down Under Geophysics) Insight using the HiQbe TM velocity model ( http://www.first-geo.com/products/hiqbe/australia) and then gridded in Petrosys™ software.
Sequence stratigraphic names were aligned with the North West Shelf common stratigraphic nomenclature (after Marshall & Lang, 2013), and with the internationally accepted Geologic Time Scale 2016 (Ogg et al., 2016).
The description of the input datasets used to construct these surfaces are in Tables 1, 2 and 3.
