MPD allows for dynamic well control offshore
When drilling offshore – particularly in deepwater – the distance between the BOP on the seafloor and the rig can potentially leave the riser, as well as the rig, exposed to kicks. “If, for example, an influx or a kick gets past the BOPs, it can travel up the riser. As it gets closer to atmospheric pressure, it can then unload at an exponential rate, causing danger to the personnel, the equipment and of course the environment,” said Guy Feasey, VP-Sales and Marketing, Well Integrity, Weatherford. Managed pressure drilling (MPD) can account for these influxes. It can also provide drillers with additional options on how to deal with these influxes, aside from simply shutting in the BOP.
