What’s The Hydro-static Pressure? |
|
Answer» Ph is the pressure exerted by the weight of a liquid on its “CONTAINER Ph is the pressure exerted by the drilling fluid to offset the pressure exerted by the formation fluid Ph (PSI) = 0.007 * TVD (ft) * Mud wt. (PCF) Ph (PSI) = 0.052 * TVD (ft) * Mud wt. (PPG) Sufficient HYDROSTATIC pressure is required to prevent the borehole wall from caving in and to keep formation fluid from entering the wellbo Ph is the pressure exerted by the weight of a liquid on its “container Ph is the pressure exerted by the drilling fluid to offset the pressure exerted by the formation fluid Ph (PSI) = 0.007 * TVD (ft) * Mud wt.
