Formula Reference

MAASP Calculation

MAASP = (FG_shoe - MW) x 0.052 x TVD_shoe Where: FG_shoe = Fracture gradient at shoe (ppg) MW = Current mud weight (ppg) TVD_shoe = TVD at casing shoe (ft)

Maximum Kick Volume

V_kick = (MAASP / (0.052 x MW - Kick_gradient)) x Ann_capacity Kick Height = V_kick / Ann_capacity

Kill Weight Mud

KWM = Pp + SIDPP / (0.052 x TVD) Where: Pp = Pore pressure (ppg) SIDPP = Shut-in drill pipe pressure (psi)
