A method of monitoring pore pressure, comprises the steps of:(a) providing downhole in a well a sealable container,(b) sealing in the container a sample of fluid at a baseline pressure and a sample of a formation having an initial pore pressure,(c) measuring the change in pressure of the fluid sample, the pressure of the fluid sample and the pore pressure of the formation sample sealed in the container tending to equalize over time, and(d) estimating the initial pore pressure relative to the baseline pressure from the measured change in fluid sample pressure.
