Squeeze cementing is considered a method of
____________________
a. Primary cementing
b. Plug-back cementing
c. Secondary cementing
d. None of the above. - Answer-C
List four different possible purposes (important reasons)
for using cement in a well. - Answer-a) Isolation of casing
shoe
b) Isolation of production zones - prevent cross-flow
between intervals at different pressures
c) Protection of water zones - prevent drilling fluid
contamination of aquifers
,2|Page
d) Isolation of problem interval - extreme losses, well
control, side-track
e) Protection of casing - from corrosive formation fluid
f) Casing support - support for surface casing, for
example.
List four types of cement jobs (applications) that were
discussed in class. - Answer-a) Cementing casing
b) Setting cement plugs
c) Squeezing cement at casing shoe
d) Repair casing leaks
e) Seal off perforations
f) Combat loss circulation problems, etc.
The failure of a float collar during a cement job could lead
to:
A. Fracture the formation at casing shoe
B. Reduce significantly the setting time of the slurry
C. Have to cut (drill) more cement than what was initially
predicted
D. Premature setting of the cement
, 3|Page
E. Higher top of cement in the annular - Answer-C
What is a good example of a problem that leads to poor
cement jobs?
A. High density mud weights
B. Distance between float collar and casing shoe too small
C. Poor centralization and poor hole conditions
D. High displacement speed of cement slurry with no
delays
E. Drilling the interval with reduced mud cake thickness -
Answer-C
In order to avoid buckling of the drill string while drilling,
we must:
A. Always keep the entire drill string under tension.
B. Make sure that neutral point is right below the drill-
pipes.
C. Use a WOB 30% above the total drill collar's weight.
D. Consider to increase the mud weight for reducing the
total buoyance.
E. None of the above. - Answer-B
