The sounding level of 12 lb. per gallon mud in mud pit 1S of the COASTAL DRILLER is 5.5 feet. What is the weight of the mud?

Correct Answer: Option B — 114.37 kips

Using the Coastal Driller's tank capacity tables, a 5.5-foot sounding in mud pit 1S corresponds to a specific volume. Multiplying this volume by the mud density of 12 lb/gal and converting to kips yields 114.37 kips. Accurate sounding is vital for monitoring mud inventory and vessel stability.
