I would like to have a discussion on pressure bleed-off from a overpressured shale with time. If it happens then what are the processes governing this mechanism and how does it happen? Shale which having high temp, more than 80-90 deg C, (thermal stress dominated condition) shows mostly normal pressure. So, does thermal history play a major role for bleed-off or time with other physical processes play the main role? Also, share any example of thermally stressed high temperature overpressured shale?
