Drilling waste management systems are packages of different functions for drilling waste management. Usually include high G drying shaker, an auger feeder or screw conveyor, a skid-mounted cuttings dryer, and a decanter centrifuge with a telescopic skid, drilling cuttings tank, or mud skips.

The process of drilling waste management

​

As the drill bit grinds rocks into drill cuttings, these become entrained in the mud flow and are carried to the surface. In order to get back into the mud of the recirculating mud system and to make the solids easier to handle, the solids must be separated from the mud. The first step in removing the cuttings from the mud involves circulating the mixture of mud and cuttings over vibrating screens called drying 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 The liquid mud passes through the screens and is recirculated back to the mud tanks from which mud is withdrawn for pumping downhole.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 shaker screens; the vibratory action of the shakers moves the cuttings down the screen and off the end of the shakers to a point where they can be collected and stored in a tank or pit for further treatment or management. Often, two series of drying shakers are used. The original series (primary shakers) uses coarse screens to eliminate only the larger cuttings.

​

The second series (secondary shakers) utilizes fine mesh screens to remove much smaller particles. In general, divided drill cuttings are coated with a large quantity of drilling mud roughly equal in volume to the cuttings. Additional mechanical processing is often used in the mud pit system to further remove as many subtle solids as possible because these particles are inclined to interfere with drilling performance.

​

This automated equipment usually is the property of one of three types: 1) hydrocyclone-type desilters and desanders, 2) mud cleaners (hydrocyclone discharging on a fine screened shaker), and 3) rotary bowl decanting centrifuges. Parted select solids are associated with the larger drill cuttings removed from the drying shakers. If the solids collected by the shale shakers are still coated with so much mud that they are unsuitable for the next reuse or disposal step, or if the used mud is valuable enough to collect as much of it as possible, the solids can be further treated with drying shakers utilizing high gravitational separation, vertical or horizontal rotary cuttings dryers, screw-type squeeze presses, or centrifuges. Cutting dryers recover additional mud and produce dry, powdery cuttings.

All wells are drilled with the generation of waste. Including drilling cuttings, waste water, spent drilling fluids, completion fluids, and filtration wastes, and so on. With increasing legislation, public awareness, and minimum operator environmental standards, the drilling waste management has increased in importance and ranks in importance along side that of drilling fluids around the world.
