Abstract
An apparatus and method for cleaning, desanding, and desilting drilling mud which contains unwanted solids utilizes an enclosure divided into a plurality of compartments connected with a system of vibratory screen shaker separators, desanders, and desilters. Drilling mud is separated by a primary vibratory shaker into coarse solids which is discarded and screened liquid mud which enters a first compartment and is further separated by a desander cyclone into a lighter liquid mud faction and a heavier liquid mud faction. The lighter faction is sent back to the first compartment and recycles, the heavier faction is further separated by a second vibratory shaker and enters a second compartment, and the solids are discarded. The liquid mud from the second compartment is further separated by manifolded desilter cyclones into a heavier faction and a lighter faction. The lighter faction is sent back to the second compartment and recycles, the heavier faction is further separated by a third vibratory shaker and enters a third compartment, and the solids are discarded. The liquid mud from the third compartment is further separated by a high-speed desilter cyclone into a heavier faction and a…
