I think that WDS had some inkling that Saturn was not the end of the potential resource otherwise they would not have increased the area by approx 30% with no requested cost from PCL either in cash or an increase in their %.
I suspect that they saw something in the 2D data that they considered worth a more detailed look .... remember they had access to the PCL data room ... for a considerable amount of time ... so much so that many on here were questioning whether PCL were going to get anyone interested in joining us in PEL 87.
The Texas geophysical specialists might have had some better knowledge or ability to reprocess the 2D data for a better picture.
I do think that had the recent discoveries been made before PCL farmed out that PCL may have been able to strike a much better deal and retained a bigger percentage or more free carried wells.

Selling at that level might be doing yourself and your family a great dis-service .... you might retire but at what level.
It's not often in life when you get the opportunity to set up future generations as well as yourself .... I think that this is one of those freaky opportunities.
