The Earth sciences use compressibility to quantify the ability of a soil or rock to reduce in volume under applied pressure. This concept is important for specific storage, when estimating groundwater reserves in confined aquifers. Geologic materials are made up of two portions: solids and voids (or same as porosity). The void space can be full of liquid or gas. Geologic materials reduce in volume only when the void spaces are reduced, which expel the liquid or gas from the … WebAbstract This paper presented a new relationship of rock compressibility with porosity, which is a new formula deduced after a theoretical study of mechanics of porous media. The new formula of this paper incorporates two parameters of rock: the elastic modulus and the Poisson's ratio, which are easier to measure in laboratory than compressibility itself.
