Absolute Pressure in Subsurface Pressure Formulas

Absolute Pressure is the total pressure measured with respect to absolute zero, which is a perfect vacuum. It is the sum of the gauge pressure and the atmospheric pressure. And is denoted by P_abs. Absolute Pressure is usually measured using the Pascal for Pressure. Note that the value of Absolute Pressure is always positive.
