Shale shaker is main an solids removal equipment. Today, offshore and onshare drillings projects where more effective fluids/solids separation is required in addtion to the reduction of costs related to shale shakers performance.
AP200 desilters are capable of processing up to 240 stere per minute and can get do to cut point of approximately 35 microns. This equipment is designed to remove the sand and silt sized particles before they have a chance to break down even smaller.
This video shows how these solids control equipment (shale shaker, desander, desilter, mud cleaner, centrifuge and pumps) works.
Mineralogy of Cuttings
Drill cuttings are particles of crushed rock produced by the grinding action of the drill bit as it penetrates into the earth. Drill cuttings range in size from clay-sized particles (~ 2 μm) to coarse gravel (> 30 mm) and have an angular configuration. Their chemistry and mineralogy reflect that of the sedimentary strata being penetrated by the drill.
