We have already discussed two of the defenses against kicks when we discussed drilling fluids when we listed the objectives of the drilling fluid: - control formation pore pressures to assure desired well control (apply hydrostatic and hydrodynamic pressures in excess of the formation pore pressures to prevent fluids from entering the wellbore); - deposit an impermeable filter cake onto the wellbore walls to further prevent fluids from permeable formations from entering the wellbore. D- Preventing the flow of formation fluid into the well bore by using BOP equipment when the hydrostatic pressure in the well bore does not balance or exceed the formation pressure. The volume will decrease considerably. Drillers Admin is a group title that includes admin staff writers, and guest writers who have insights to share, but might want to remain out of the spotlight.
