After taking a kick and shutting-in the well, the surface pressures stabilize and the following kick data are recorded:

Shut-in Drill Pipe Pressure (SIDPP) = 520 psi. Shut-in Casing Pressure (SICP) = 750 psi. True Vertical Well Depth (TVDwell) = 10,000 ft. Measured Depth (MDwell) = 12,500 ft. Mud Density In Use (MDuse) = 10.0 ppg. Pit Gain (V) = 15 bbls.

What is the required Kill Mud Density to balance the formation pressure? A. 10.5 ppg. B. 10.8 ppg. C. 11.0 ppg. D. 12.0 pp

After taking a gas kick, the well is shut-in. Which one of the following methods is applied the gas expansion in the well annulus will be the most? A. Drillers Method. B. Wait and Weight Method. C. Volumetric Method. D. It is the same for the all three methods. E. It can not be decided.

While killing a well and after the Kill Weight Mud reaches the bit, suddenly Drill Pipe Pressure increases by 200 psi but Casing Pressure remains the same. What is the likely Problem? A. Choke plugged. B. One bit nozzle plugged. C. One bit nozzle washout. D. Total pump failure. E. Choke washout
