5 Questions
What is the purpose of the Marsh funnel viscosity test?
To quickly check the viscosity of drilling mud.
What is the temperature range for conducting the Marsh funnel viscosity test?
70 F ± 5 F (21 C ± 3 C).
Does the funnel viscosity measured from the Marsh funnel represent the true drilling mud viscosity?
No.
Why is the funnel viscosity measurement still useful on the drilling rig?
It is a quick and simple test for observing trends of drilling mud.
How does temperature affect the viscosity of oil-based drilling mud?
As temperature increases, the viscosity of the mud decreases.
