What is Marsh Funnel Viscosity Testing Guide about?

The document provides procedures for measuring the funnel viscosity of water-based mud (WBM) using a Marsh funnel. The funnel must be calibrated regularly and cleaned if viscosity readings are above 26 seconds per quart at 70°F. The rheology of WBM will be determined using a Fann 6-speed viscometer at 300 and 600 rpm to measure Bingham plastic viscosity and yield point according to API standards. Proper calibration and matching electrical frequencies between the viscometer and rig are important for accurate
