Hi Callsign,

There are various Aptian source rock maturity maps floating around. The one below was by Calima from when they operated PEL90. This is a modified version of the original of Bray et al. (1998). It The map is based on regional seismic lines and an interpretation of the source rock depth of burial. It can be a bit of an generalisation, but it is a reasonable way of estimating maturity during early exploration. You can see on this map the relatively more mature area to the north of Saturn. If we think that directly below Saturn is marginal in its maturity, then we can be a bit happer to know it is more mature to the north. Hopefully it migrates into Saturn. Woodside probably did some modelling of this (I'm assuming they licensed some seismic data prior to farmin). Hope that helps.
