Pump output figures. 02e), the well control system is comprised of: - the Accumulator (Item 18). Pump pressure decrease and pump stroke increase (secondary indicator of a kick): If low density fluids are displacing heavier drilling fluid in the annulus, then this will cause the pump pressure to decrease (the annular side of the u-tube is lighter than the drill pipe side of the u-tube which contains the mud pump pressure gauge). The pumps were stopped. A mud hydrostatic pressure Is greater than formation pressure Pump pressure is greater than mud hydrostatic pressure. Volume & weight of the mud.
