Abstract
hydraulic and poroelastic properties of tight rocks. This paper is devoted to an integrated study of reservoir
rocks' hydraulic transport and poroelastic properties as measured with the complex transient pore pressure experiment.
The measurements were carried out for four low-porosity low-permeability samples at a range of
oscillation frequencies and eective stresses. An apparent linear-frequency dependence of permeability was observed.
Measured frequency dispersion of drained poroelastic properties indicates an intrinsically inelastic nature
of the porous mineral rock frame. Standard Linear Model produced the bestt to the experimental poroelastic
moduli dispersion data. Biot and Skempton's coecients, estimated from poroelastic strain measurements, fall
within the presumable range of values for these rocks.
