The storativity of an elastic artesian aquifer is 0.05. If the porosity of the aquifer is 0.30, the compressibility of water (β) at 20 ◦C is 4.58∙10−10, and the thickness of the aquifer is 10 m, what is the compressibility (βp) of the aquifer matrix? Is this aquifer likely to undergo compaction if the hydrostatic pressure in the aquifer were to be decreased?
