Drilling Fluid Management & Disposal
Drilling fluid waste management and solids control of drilling mud related technical and developed situation.
Hydrocyclones are simple, easily maintained mechanical devices without moving parts. Separation is accomplished by transfer of kinetic input or feed energy into centrifugal force inside the cone. The centrifugal force acts on the drilling fluid slurry to rapidly separate drilled solids and other solid particles in accordance with Stokes’ law.

Hydrocyclones should be located so that underflow can be moved away
with a minimum of trouble and washdown water and so that they are
accessible for maintenance and evaluation.

Other than hydrocyclone and manifold plugging, improperly sized or operated centrifugal pumps are by far the greatest source of problems encountered with hydrocyclones. Centrifugal pump and piping sizing are critical to efficient hydrocyclone operation. A pressure gauge should be mounted on the hydrocyclone inlet manifold.

A viscosified seawater fluid (SG 1.1, plastic viscosity (PV) 2.0 centipoise
(cP), and yield point (YP) 12.0 lb/100 sq ft) is circulated to clean out
a cased well bore. What size of low-gravity solids will settle out with
5-micron barite particles? What is the settling velocity of 10-micron
barite particles in rig tanks? From Stokes’ law, settling velocity is:
