ABSTRACT:
Water is injected into a core sample which has been restored to a desired state of water and gas-oil saturation and which is subjected to desired conditions of pore pressure, overburden pressure and temperature. A measurement of the rate at which oil is forced from the core sample by the injected water provides an indication of the imbibition characteristics of the core sample and thus of the rock formation from which the core sample was taken. The technique utilized to establish a desired differential pressure across a core sample can also be used to calibrate a differential pressure transducer if desired.
