PPT-Porosity, Permeability and Aquifers

porosity the amount of empty space in a rock or other earth substance The higher the porosity the more water it can hold this empty space is known as pore space Porosity is how much water a substance can hold.

Must be both porous and permeable. .. Reservoir rocks are dominantly sedimentary (. Porosity and Permeability. In . order for rocks to transmit water, oil, or gas they must possess two properties, 1) porosity and 2) permeability. Porosity can be of two types. The first is inter-granular porosity which consists of pores between grains such as the quartz grains in a sandstone . What happens to rainwater after it reaches the Earth’s surface?. Storage.
