The most severe well control problems
while drilling in deep water is that of a
kick when no protective casing is set.
The most dangerous of these problems
is that of the loss of buoyancy of the
drilling vessel. Fig.4 and 5 illustrate

History matching technique, seismic
interpreters have now found small
anomalies that represent the kicking
zones in the known blowout cases. 105 Well control measures
Surface diverter systems are illustrated
in Fig.7. Basis of it is a flow diverting
mechanism, and annular preventer or
diverter bag, and two large diameter
diverter lines placed at 180 degree
angles from each other.

If protective casing is set deep enough
to achieve fracture gradients in excess
of kick caused equivalent mud weights,
then the kick can be killed using
