7,700 feet of drill pipe is to be tripped out of a wellbore full of drilling mud. The hydrostatic pressure at 7,700 feet with the drill pipe in the hole is 4,350 psi. The driller pulls the drill pipe out of the hole, but does not keep the hole full of fluid while pulling the drill pipe out. The fluid level in the well drops by 1,775 feet due to the volume of the drill pipe being removed. The hydrostatic pressure at 7,700 feet is now 3,250 psi. What is the change in hydrostatic pressure, in psi?
