Drill Cuttings Separation from Drilling Mud

Drilling mud is used to control subsurface pressures, lubricate the drill bit, stabilize the well bore, and carry the cuttings to the surface, among other functions. Mud is pumped from the surface through the hollow drill string, exits through nozzles in the drill bit, and returns to the surface through the annular space between the drill string and the walls of the hole.   As the drill bit grinds rocks into drill cuttings , these cuttings become entrained in the mud flow and are carried to the surface. In order to return the mud to the recirculating mud system and to make the solids easier to handle, the solids must be separated from the mud. The first step in separating the cuttings from the mud involves circulating the mixture of mud and cuttings over vibrating screens called shale shakers. The liquid mud passes through the screens and is recirculated back to the mud tanks from which mud is withdrawn for pumping downhole. The drill cuttings remain on top of the shale sha

Drill Solids Cuttings Separation from Liquid Drilling Mud

Drilling mud is employed to regulate subsurface pressures, lubricate the drilling bit, stabilize the well bore, and carry the drill solid cuttings to the surface, among alternative functions. Drill mud is pumped-up from the surface through the hollow drill string, exits through nozzles within the drilling bit, and returns to the surface through the ring-shaped   area between the drill string and also the walls of the outlet. As the drilling bit grinds rocks into drill cuttings, these drill cuttings become entrained within the mud flow and area unitcarried to the surface. so as to come the mud to the recirculating mud system and to create the drill solids easier to handle, the drill solids  should be separated from the mud. the primary step in separating the drill cuttings from the mud involves current the mixture of mud and drill solids  over vibrating  shale shaker screens referred to as sedimentary rock  shale shakers . The liquid mud passes through the screens and is r
