This section provides additional thoughts and considerations concerning solids-control equipment. The practical operational guidelines for equipment discussed here may not apply to all drilling applications. These guidelines (in italics) were developed as part of API RP 13C. The discussion beneath each captures some of the comments by committee members as they debated the guideline before approval.
Mud cleaners are equally effective for both weighted and unweighted drilling fluids and effectively lower both drilling fluid expenses and disposal costs.
The weighted mud flows to the inlet head section of the desander and/or desilter entering the hydrocyclones for separation of particles. Mud leaving the underflow is further screened with fine mesh to separate larger particles allowing only barite size particles to pass through the screen returning and recovering then the clean mud.
The purpose of the mud cleaner is to remove drilled solids larger than barite. Mud cleaner could be useful cleaning facility at many filed of mud management.
