Complete the kill sheet and then answer questions 1 to 10. Please round calculations as per good well control practice. Well data: Hole size 8 12 inches Hole depth 7,800 feet MD, 6800 ft TVD Casing shoe depth 9 5/8 inches, 4000 ft MD/TVD Internal capacities: Drill pipe 5 inch (S-135-NC50), capacity 0.0178 bbl/ft Heavy wall drill pipe 5 inch, length 400 ft, capacity 0.0088 bbl/ft Drill collars 6 inch x 213/16inch, length 600 ft, capacity 0.0077bb/s/ft Annulus capacities: Drill collars in open hole 0.0292 bbl/ft Drill pipe and HWDP in open hole 0.0459 bbl/ft Drill pipe and HWDP in casing 0.0505 bbl/ft Mud pump data: Pump output at 95% volumetric efficiency 0.102 bbl/stroke Slow circulation rate data: @ 40 spm = 400 psi @ 45 spm = 500 psi Other relevant information: Drill pipe, 5 inch closed end displacement 0.0254 bbl/ft Surface line volume 14 bbls Formation strength test data: Surface leak-off pressure with 10.0 ppg mud 1500 psi Kick Data: Shut in drill pipe pressure 700 psi Shut in Casing pressure 970 psi Recorded pit gain 21 bols Mud weight in hole 10.2 ppg The well will be killed using the Wait and Weight method
