Energy Well Integrity Feedback
I believe that there should be additional information on the level of blow
out prevention required
while drilling shale gas wells in this document on well intergrity. The only
reference in the
document to blow out prevention is on page 7 : “When the cement has set
adequately, a flange
is welded on to the casing, and a blow-out preventer and other sealing
equipment for assurance
of security and unimpeded fluid circulation are firmly bolted to the flange
so that deeper drilling
can be executed with minimal risk”.
Regulations in Europe are driving up the cost of drilling shale gas wells by
introducing regulations
requiring very high standards of well control that many engineers would
consider excessive.
Could the blow out prevention requirements be spelled out in the Nova Scotian
document to
avoid any mis-interpretation?
Regards,
Nick
