1. What is the primary objective of well integrity management?
A. Increase drilling speed
B. Reduce fuel consumption
C. Ensure containment of formation fluids throughout the well lifecycle
D. Improve cement color consistency
Answer: C. Ensure containment of formation fluids throughout the
well lifecycle
Rationale: The main goal of well integrity management is to maintain
two independent barriers that prevent uncontrolled release of
formation fluids. This protects personnel, the environment, assets, and
production operations throughout drilling, completion, production,
intervention, and abandonment phases.
, 2. Which of the following is considered a primary well barrier
element?
A. Mud logger
B. Cement sheath
C. Generator
D. Pipe rack
Answer: B. Cement sheath
Rationale: The cement sheath forms part of the primary well barrier
by isolating formations and preventing fluid migration in the annulus.
Effective cement placement is essential for zonal isolation and well
integrity.
3. What is meant by “zonal isolation” in well integrity?
A. Separating drill crews by work area
B. Preventing communication between subsurface formations
C. Installing extra casing strings
D. Monitoring weather conditions offshore
Answer: B. Preventing communication between subsurface formations
,Rationale: Zonal isolation prevents fluids from moving between
formations or reaching the surface unintentionally. Proper casing and
cementing operations are critical to achieving this objective.
4. Which document typically defines barrier requirements and
verification standards?
A. Catering policy manual
B. Well integrity management system
C. Payroll ledger
D. Vessel manifest
Answer: B. Well integrity management system
Rationale: A Well Integrity Management System (WIMS) establishes
procedures, standards, responsibilities, testing requirements, and
verification processes necessary to maintain safe well operations.
5. What is the purpose of a casing string?
A. Increase mud pit volume
B. Support and isolate the wellbore
C. Cool the drill floor
D. Measure production rates
, Answer: B. Support and isolate the wellbore
Rationale: Casing provides structural support, isolates formations,
prevents well collapse, and assists in pressure containment. Multiple
casing strings are often used to manage varying formation pressures.
6. Which component is commonly used to seal the annulus between
casing and formation?
A. Drilling line
B. Cement
C. Kelly hose
D. Crown block
Answer: B. Cement
Rationale: Cement is pumped into the annulus to provide zonal
isolation, structural support, and pressure containment. Proper
cementing is fundamental to long-term well integrity.
7. What is a sustained casing pressure (SCP)?
A. Temporary pressure during circulation
B. Pressure that rebuilds after being bled off
