In addition, multiple source rock units have been identified in compartmentalised Jurassic‐Cretaceous source pods, resulting in four distinct petroleum systems. Three main reservoir-seal pairs, associated with stratigraphic traps, have been identified within the Cretaceous succession (Rollet et al., 2016b). Isochore maps and depositional environmental models are used to map the distribution of key source, reservoir and seal units. This work was completed as part of a regional assessment of CO 2 storage potential in the Browse Basin (Rollet et al., 2016a). Sixty key wells and 2D and 3D seismic data have been interpreted to produce palaeogeographic maps and depositional models for the Jurassic and Cretaceous successions (Abbott et al., 2016 Rollet et al., 2016a, b). The sequence stratigraphic interpretation is based upon a common North West Shelf stratigraphic framework that has been developed in conjunction with industry, and aligned with the international time scale (Gradstein et al., 2012 Marshall & Lang, 2013 Kelman et al., 2016). the extent and distribution of existing and newly identified hydrocarbon plays.burial and thermal history, source rock maturity and generation history,.petroleum fluid composition, phase behaviour and geochemical typing,. source rock geochemical characteristics,.3D distribution of reservoir and seal pairs, and areas with enhanced source rock development,.This multi-disciplinary study integrates sequence stratigraphy, geochemical and regional petroleum systems analyses to better understand: Geoscience Australia is undertaking a reassessment of the petroleum prospectivity of the Browse Basin to identify the various hydrocarbon sources and high-grade areas of increased liquids prospectivity within this primarily gas-prone province. However oil discoveries are presently sub-economic and confined to the central Caswell Sub-basin (Caswell) and Yampi Shelf (Cornea, Gwydion). It is poised to become Australia's next major conventional liquefied natural gas (LNG) province with the Ichthys, Prelude and Concerto fields currently under development and recent discoveries made at Burnside, Lasseter and Crown/Proteus in the Caswell Sub-basin. le Poidevin et al., 2015 Kuske et al., 2015). The Browse Basin located offshore on Australia's North West Shelf hosts considerable gas and condensate resources (e.g.
