The values of barometric efficiency and tidal strain sensitivity of a system the well-reservoir are estimated on the data of synchronic water level and atmospheric pressure observations on the well UZ5, Kamchatka. It is show, that the hypothesis of the confined elastic response of the reservoir to the atmospheric and tidal loading can be accepted. Porosity and parameters of the reservoir (drained matrix compressibility, coefficient of pore pressure (Skempton’s coefficient), shear modulus, and specific storage) are evaluated on the basis of the theory poroelasticity. The behavior pattern of water level in the well UZ5 is considered by periodical variations of pore pressure.
