The storage capacity of the flow pump experimental system influences the transient response of pore pressure, and hence affect the evaluated values of storage coefficient of test specimens from experiments. To test the effect of the storage capacity of experimental system, sandstones and granites were tested by flow pump methods. The storage coefficients of sandstone obtained from the flow pump tests were very close to those from the poroelastic parameters, however the obtained storage coefficients of granites samples were not consistent between the two methods. We consider the difference to be caused by the ratio of the storage capacity of the system to that of the specimen, and this ratio should be less than 0.3 to obtain the storage coefficient with sufficient accuracy.
