Figure 2. Canning Basin stratigraphy and source rock potential: a) generalized time stratigraphy, rock units, oil production, oil and gas shows, and rock units present within Yulleroo 1 (Y) , Acacia 1 and 2 (A), Kidson 1 (K), and Willara 1 (W) wells used for petroleum generation history reconstructions; b) organic richness, facies and maturity of Permian, Carboniferous, Devonian, and Ordovician successions within the Canning Basin: i) generating potential, organic richness versus potential yield; ii) organic facies from RE, Tmax versus hydrogen index; iii) thermal maturity from RE, Tmax versus production index.
