If a slug of heavy mud is pumped into the drill pipe before tripping, what will happen to bottom hole pressure (BHP)? a. BHP will increase due to heavy slug b. BHP will decrease due to drop in mud level in the drillstring c. BHP will stay the same, as hydrostatic pressure will balance out between annulus and drillstring 11 / 30 11.

Which of the following are reasons why kicks occur? a. The additional ECD on the formation is too high after the pumps are shut off causing a reduction in the hydrostatic fluid column in wellbore. b. If the fluid density is too high after pumping a slug allowing a kick to enter the wellbore. c. Formation Pressure is greater than Mud Hydrostatic Pressure. 21 / 30 21. What is the definition of Bottom Hole Pressure? a. Total pressure acting on the bottom of the well b. none of the above c. Loss of mud to formation d. Pounds per square inch 22 / 30 22.
