Hydrostatic pressure is the total fluid pressure created by the weight of a column of fluid, acting on any given point in a well. Hydro means water, or fluid, that exerts pressure like water, and static means not moving. So hydrostatic pressure is the pressure created by the density and height of a stationary $($not moving$)$ column of fluid.

A well that has a fluid density of $0\mathrm{.}053247\frac{l{b}_m}{i{n}^3},$ a measured depth $($MD$)$ of $8750ft,$ and a true vertical depth $($TVD$)$ of $7000ft,$

What is the hydrostatic pressure at the bottom of a well?
