n: the pressure exerted by the rock strata on a formation of interest. It is usually considered to be about I pound per square inch per foot (22.621 kilopascals per metre).

n: overburden pressure of some point in layer refers to the total quality of layer base and fluid in the pores above the layer causes the pressure.

n: the stress that the pressure of given layer bears overburden rock quality causes the base and the fluid in the pores is devided by the vertical depth of the layer.

n: capacity beyond what is normal, allowed, or desirable.
