... and the kickback valves open. During the ESD valves closure, the pipeline can be exposed to a risk of high surge pressures exerted onto the wall. A pressure surge or liquid hammering phenomenon in piping systems can be caused by a fluid in motion forced to stop or change direction suddenly (rapid momentum change...

... Abstract Uncontrollable kicks are the most costly events that occur while drilling for oil and gas. Formation water flow sometimes turns to kicks that lead to life threatening and environmentaly disastrous blowouts. Prediction of the possible abrupt pressure surges that characterize...

... that a sudden pipeline shutdown has a symmetry where a pressure reduction (which can easily result in the creation of a vacuum strong enough to pull gas out of solution, followed by explosive recompression of that resultant gas phase) occurs at the inlet of the pipe equal in magnitude to the pressure surge...

... (Equivalent Circulating Density), is lost; The bottom hole pressure drops; and often ‘undershoots’ the static pressure by hundreds of psi, sometimes inducing a kick and often damaging the exposed formation; When circulation is re-started, the down hole pressure surges and ‘overshoots’ the flowing...
