Abstract:
Systems and methods are disclosed for accurately determining a pore pressure of a subsurface formation (20) penetrated by a wellbore (40). The systems and methods provide for measuring pressure and temperature at a measuring location proximal to the wellbore for a predetermined amount of time, storing the measurements, communicating the measurements and processing the pore pressure from the pressure and temperature measurements. The measuring location may be a location in a channel (50) drilled from the wellbore into the formation.
