presssurized zone was 40metres thick ?, page-32

I have also had that thought Doc, but I feel like I remember that the gas-water contact was interpreted at a depth of ~3300m. I can't recall how definitive this was, nor how much confidence they have regarding the accuracy of the depth calculations. 300m is a significant difference between the two, I would have expected greater accuracy than that (though my study of geophysics ended after 2nd uni which was many moons ago).

Need someone to dig up documentation where they have stated the depth of the interpreted gas-water contact. I'm at work, too busy, anyone else got time/know where to find it?
