Hydrostatic Pressure in a Well - Calculation Questions

Fill in the blank: The formula to calculate hydrostatic pressure is Pressure (psi) = 0.052 * Mud Weight (ppg) * ________.

• A) True Vertical Depth (ft)

• B) Mud Density (lb/ft³)

• C) Wellbore Geometry

• D) Formation Pressure

What is the hydrostatic pressure at the bottom of the well at 5,000 feet and the drilling mud being used has a density of 8 pounds per gallon?

• 1,080 psi

• 2,080 psi

• 3,080 psi

• 4,080 psi

Hydrostatic pressure is crucial for well control because it can ________ the formation pressure.

• increase

• counterbalance

• ignore

• reduce
