Density Archimedes' principle
The mud property that helps to support the weight of the drill string is the mud gradient.
Mud weight is the property which creates a buoyancy and supports a part of drill string there by reducing the dry weight of string.
Mud weight creates buoyancy for thr drill string
MUD WEIGHT AND MUD VISCOSITY
The property of mud responsible for supporting tubulars is the Mud Weight. It is measured in pounds per galon
the density of the mud has a great effect on supprting the weight of the drill string
Higher mud density means higher buoyancy factor that means decreasing the apparent weight of the drill string.
