What function of drilling mud helps c) Maintaining hydrostatic pressure
prevent the influx of formation fluids
into the wellbore?
Excessive mud weight may cause b) Lost circulation
which of the following hole
problems?
What is one of the main roles of c) Supporting the walls with hydrostatic pressure
drilling mud in stabilizing the
wellbore?
One of the functions of mud is to form c) Seals the wellbore wall to reduce filtrate invasion
a filter cake. What is the main benefit
of this filter cake?
Which hole problem can be caused c) Cuttings accumulation and stuck pipe
by poor hole cleaning due to
inadequate mud properties or flow
rate?
Drilling fluid helps to prevent c. Maintaining hydrostatic pressure
formation fluids from entering the
wellbore by:
, A critical function of the drilling fluid d. Cleaning the hole effectively
during directional drilling is:
Drilling fluid helps reduce wear on b) Reducing friction
drill string components primarily by:
Which additive is commonly used to c) Barite
increase the density of drilling fluid?
Which of the following additives is b) Filtration reducer
used to control fluid loss in drilling
mud?
What is the role of bentonite in water- c) Act as a viscosifier
based mud?
Which property of drilling mud d) Gel strength
directly affects its ability to suspend
cuttings with no circulation?
What property is typically measured b) Viscosity
using a marsh funnel?
Excessive solids in the drilling fluid c) Increased wear on mud pump liners and pistons
can lead to:
