====================================================
1. A primary indicator of a well kick during well intervention
operations is:
A. Increase in pump pressure
B. Decrease in fluid temperature
C. Increase in flow rate despite constant pump output
D. Reduction in annular velocity
Rationale: A kick is typically identified by an unexpected influx of
formation fluids into the wellbore. One of the earliest signs is an
increase in return flow rate while pump rate remains constant,
indicating formation fluids are entering the well system.
2. The main purpose of a Blowout Preventer (BOP) is to:
A. Increase production rate
B. Circulate drilling fluids
, C. Control unexpected wellbore pressure and prevent
uncontrolled flow
D. Measure formation pressure
Rationale: A BOP is a critical well control device designed to seal
the wellbore and prevent the uncontrolled release of formation
fluids during intervention or drilling operations.
3. Which fluid property is most important for maintaining primary
well control?
A. Viscosity
B. Color
C. Density
D. pH level
Rationale: Fluid density determines hydrostatic pressure, which
is the primary barrier preventing formation fluids from entering
the wellbore.
4. A “shut-in well” means:
A. The well is producing at maximum rate
B. The well is circulating fluids
C. The well is closed in with no flow at surface
, D. The well is being perforated
Rationale: A shut-in condition means all outlets are closed,
isolating the wellbore and allowing pressure stabilization or
monitoring.
5. The first action when a kick is suspected during intervention is to:
A. Increase pump rate
B. Open all valves
C. Shut in the well
D. Continue circulation
Rationale: Immediate well shut-in is required to prevent further
influx and regain control of the well.
6. What is the function of kill weight fluid?
A. Increase production
B. Reduce corrosion
C. Provide hydrostatic pressure greater than formation pressure
D. Clean the tubing
Rationale: Kill fluid is designed to exert sufficient hydrostatic
pressure to counteract formation pressure and stop influx.
, 7. In well intervention, a “barrier” is defined as:
A. A production valve only
B. Any fluid in the well
C. Any element that prevents uncontrolled flow of well fluids
D. A drilling bit
Rationale: Barriers include mechanical and fluid systems that
maintain well control integrity.
8. The most common cause of a well kick is:
A. Excessive casing strength
B. Too high pump efficiency
C. Insufficient hydrostatic pressure in the wellbore
D. High cement quality
Rationale: If hydrostatic pressure falls below formation pressure,
formation fluids can enter the wellbore.
9. Which device is used to seal around a wireline during
intervention?
A. Choke manifold
B. Mud pump
C. Wireline blowout preventer (BOP stack)
