Learning Objective:
Recognize
drilling difficulties and the
development of a water well.
6-68.
One method of regaining a loss
of circulation that takes place
during well drilling is to
circulate the cuttings away from
the drill bit with plenty of
water.
1.
True
2.
False
6-69.
Undue wear of the drill pipe is
an indication of a crooked drill
hole.
1.
True
2.
False
6-70.
During a drilling operation, the
drill pipe may stick due to which
of the following causes?
1.
A mud pump of inadequate
capacity
2.
Allowing the drill pipe to
stop and remain stationary
in the hole
3.
Mud balling up around the
drill collar and bit
4.
All of the above
6-71.
The drill pipe of your rotary
well-drilling rig becomes stuck
with drill cuttings that have
accumulated in the hole.
How
can you remedy the situation?
1.
Pull upward on the pipe
with jacks
2.
Circulate heavy mud while
trying to turn the pipe
3.
Pour oil along the sides
of the pipe
4.
Pull upward on the pipe and
circulate clear water around
it

Which of the following is a
practical use of a fishing tool?
1.
Recovery of a twisted-off
drill pipe
2.
Recovery of a wrench that
falls into the drill hole
3.
Recovery of a drill pipe that
falls into the drill hole
4.
Each of the above
6-73.
The setting of the casing and
screens is the first operation
in developing a well after the
borehole is drilled.
1.
True
2.
False
6-74.
Gravel packing is placing ungraded
aggregate on the outside of the
casing to allow for more pro-
duction and prevent fines from
entering the well pump.
1.
True
2.
False
6-75.
In completing a developed well,
the space between the well wall
and casing is cemented to
1.
trap the drilling mud
below the water table
2.
keep surface water or
contaminated water from
seeping into the aquifer
3.
prevent the drilling mud
from solidifying
4.
All of the above
