LA 4-32 Water Well Drilling Contractor Exam
Questions and Correct Answers
1: Under Louisiana regulations, what is the minimum setback distance for a water well from a
septic tank?
A. 25 feet
B. 50 feet
C. 100 feet
D. 200 feet
CORRECT ANSWER: B. 50 feet
Rationale: Louisiana Administrative Code (LAC 43:XIX) typically requires a minimum 50-foot
horizontal separation between a water well and a septic tank to prevent contamination from
wastewater.
The purpose of using a pre-flush in cementing operations is ___________________
a. Accelerate the setting time.
b. Remove some of the wall cake.
c. Provide a spacer between the drilling mud and the slurry.
d. Increase the density of the slurry.
Correct Answer
B&C

and keeping fluid volume
rate constant.
, C. Increasing both fluid
pressure and the fluid
volume rate.
D. Decreasing both fluid
pressure and fluid volume
at a slow but constant
rate.
E. All above are correct
Correct Answer
C
Question 9
In determining the volume of an open hole with the diameter-squared method, a slightly larger
figure for
diameter should be used to allow for _______________
a. Larger casing ID.
b. Hole enlargement
c. Errors in calculation
d. An extra amount of cement slurry as a safety factor.
Correct Answer
B
Question 10
(T/F): The well control system allows you to close the well at surface, to move the
drill string under existing pressure in the well and to divert flow away from
rig personnel and equipment.
Correct Answer
