EQUATION CORRECTS KILL-WATER DENSITY VALUE IN DEEP, HOT WELLS

D. Ram Babu Oil India Ltd. Duliajan, India A pressure-depth relationship is derived for a water column in deep and hot wells. In these wells, calculations based on normal water gradients may lead to well control problems. Often, plain water is the kill fluid for well servicing operations. Apart from its ready availability, another major advantage of using water is that its density is higher than that of the reservoir fluids. This allows a column of water to exert sufficient static pressure
