The flux between a well and a water-saturated permeable elastic layer caused by an oscillating rigid impermeable overburden is examined for plane and axi-symmetric flows. It is assumed that the overburden height is much greater than the layer thickness. Estimates of the amplitude of the water-level fluctuation in the well are made when the oscillation is caused by a small periodic gravity perturbation describing an Earth tide. It is shown that the maximum possible amplitude is inversely proportional to the layer porosity, and is attained only when the length (radius) of layer influencing the well exceeds a critical length. This critical length is much smaller for axi-symmetric flow than for plane flow. The maximum amplitude can be of order 1 cm or greater for low-porosity layers under an overburden of large depth.
