SELECT TWO ANSWERS
a) Pulling out of the hole to change the bit.
b) Raising the drilling fluid yield point.
e) Minimizing the time during a connection when the pumps are switched off
d) Controlling drilling rate so that only one slug of connection gas is in the hole at a time.

SELECT TWO ANSWERS
a) Increase in pump pressure.
b) Reduction in rate of penetration.
