The article offers information on the benefits of marsh funnel viscosity test to drilling contractors in the drilling industry. It notes that drilling contractors prefer the funnel viscosity test that utilizes either mineral like bentonite or polymer-based drilling fluids or slurry. However, funnel viscosity gauges the thickness of a drilling fluid but does not accurately determine the conveyance of fluids and other functions in an effective drilling project.
