An apparatus and process for measuring the formation gas pore pressure in drilling cuttings samples in a container. The Apparatus includes vertical holder for container, for placing the cutting sample and pipette for adding measurable quantity of liquid. The container may be vibrated to facilitate separation by grain size. The process includes measuring the gas bubbles size and volume in the test tube and the height of liquid covering the bubble. The volume and the pressure of the gas emitted out of the pores is calculated. By adding/subtracting liquid and/or pressure to the sample and increasing/decreasing the height and the pressure of the liquid on the pore, the test is repeated and the measurements documented in the tables for math processing to obtain the error corrections and standard deviation of the measurements. The results are expressed in Emission=V/P=mm3/Pa, Total Volume=V=mm3, Maximum Pressure=P=Pa.
