Thanks GH. Just out of curiosity,here is what I've wondering about!-It won't make any difference to anything of course,except maybe help my understanding! 1)Quite a long time back it was mentioned that the bottom hole temp was estimated to be near 535+/-degrees F.on this well.(if I recall correctly).At that temp.,would water in contact with that much heat boil and cause a phase change to steam and cause the upper liquid water to sort of get puked out of the casing at surface?(I suppose that there could easily be over 5000'where the boiling point of water would be exceeded at atmospheric pressure).Or..,would the water in the wellbore remain stable because of the extreme hydrostatic pressure down there,preventing boiling from occurring?(probably wouldn't boil, right?) 2)I remember reading an article back in about 1979 of a blowout in Oakahoma I think it was,when they drilled into what they called a geopressurized zone.It seems to me they mentioned pressures of somewhere around 17000-20000psi.bhp.(or something like that)If so,and there is that kind of pressures in this well,would that be the reason maybe for running a liner inside of the casing and having it cemented in place,in order to prevent the casing from collapsing due to the high differential press. between the reservoir pressure outside and what the hydrostatic press.inside the casing could provide to offset it,prior to the well being perfed?-As soon as it was perfed of course,equilibrium would occur,and then no collapsing of casing-just that the whole casing and w/h would be subjected to extreme outward pressures! GH,as mentioned,these are just a couple of things I've been wondering about,and any response from you to try and help me understand would be greatly appreciated.-Thank you,LP
