Title: Deepwater well control offers complex options

The basics of successful well control in floating drilling are the same as those for other types of drilling, i.e., detect influxes early, shut the well in quickly, and pump the influx fluid out using the constant bottom hole pressure technique. Some aspects of well control in floating drilling are more complex because of the motion of the drilling vessel with respect to the seafloor, and the reduction in fracture gradient at the last casing seat as water depth increases. Another difference is the increased friction pressure losses and rapid changes in hydrostatic pressure introduced by the length of the smalldiameter choke and kill lines from the blowout preventer at the seafloor to the choke manifold at the surface.
