Cheers OG. Calima's map has a little extra generosity in terms of maturity than the Bray & Lawrence maps; a bit of re-drafting, no doubt with some science behind it, but which would have helped with their farmout to Tullow. With the hindsight of the Venus & Graff etc..., however, it seems it fits the results and so Calima got it right I reckon (in that area at least). Graff and LaRona have a high associated gas content so a late oil mature to gas maturity still fits the model. Having said that, my take on Graff (& LaRona) is that the charge is primarily from further west, where maturity is similar to that for the Venus source rocks (I've seen some seismic sections where the Aptian could be interpreted as missing directly below Graff). Most importantly for us, it suggests Saturn is well located. Hopefully all the other elements we need are working.

Kind regards,
