WebJul 12, 2015 · The below calculation relates to pressure while bullheading. Maximum End of Tubing Pressure (psi) = Fracture Pressure (psi) – (Kill Weight Mud (ppg) x 0.052 x End of Tubing TVD (ft)) – Initial Average Fluid Density (ppg) x 0.052 x (Top of Perforation TVD (ft) – End of Tubing TVD (ft)) WebBased on static conditions before beginning to pump, calculate the initial surface pressure limit for a Bullheading operation. Well Information: SITP = 2,100 psi SICP = 0 psi Top Perforation = 9,200 feet MD / TVD Bottom Perforation = 9,600 feet MD / TVD Formation Fracture Gradient = 0.598 psi/foot Formation Pressure Gradient = 0.364 psi/foot a ... 19億円
