Is sandstone permeable.

A confined aquifer is an aquifer below the land surface that is saturated with water. Layers of impermeable material are both above and below the aquifer, causing it to be under pressure so that when the aquifer is penetrated by a well, the water will rise above the top of the aquifer. A water table--or unconfined--aquifer is an aquifer whose upper water surface …A sandstone is typically porous and permeable. Shales are porous but have a lower permeability because the finer grain size creates smaller pore spaces. Igneous rocks …Spontaneous (SP) log. The SP curve is a continuous recording vs. depth of the electrical potential difference between a movable electrode in the borehole and a surface electrode. [1] Adjacent to shales, SP readings usually define a straight line known as the shale baseline. Next to permeable formations, the curve departs from the shale baseline ...Permeable paving is a relatively recent introduction to the British and Irish paving markets, but one that is set to dominate the trade in the coming years due to its critical role in the future of our towns and cities.
