Drilling Mud Recovery and Drilling Cuttings Reuse



Most OBM drilling mud is disposed once drilling work finished. In contrast, much oil-based drilling mud and synthetic-based drilling mud is recycled possible. Sometimes the physical and chemical properties of the used drilling mud have degraded somewhat, and the drilling mud must be processed to rejuvenate the necessary properties.

In other cases, drilling mud have been degraded sufficiently that it cannot economically be reused as new drilling mud.

There are many relatively simple processes that can be used on drilling rigs to capture clean drilling mud that would otherwise be discarded and return for reuse. Like pipe wipers, mud buckets, and vacuuming of spills on the rig floor.

Recovery of mud during tank cleaning may also allow the mud to be reused. Solids control equipment, like centrifuges, can be used to remove solids from the recirculating mud stream.

Some new drilling mud formulations are designed to aid vegetative growth so that the drilling mud can be land-applied. These could have application in horticulture or in reclamation of damaged or low-quality soils.


Drilling cuttings are made up of ground rock coated with a layer of drilling fluid. Most drill cuttings are managed through disposal, although some are treated and beneficially reused. Before the cuttings can be reused, it is necessary to ensure that the hydrocarbon content, moisture content, salinity, and clay content of the cuttings are suitable for the intended use of the material.

Some drilling cuttings, particularly when a saltwater-type mud was used to drill the well, may need washing to remove dissolved salts prior to beneficial use. Water used for washing can be disposed of in an injection well. (yuan.yan@adkosun.com)

Treated cuttings have been used in various ways:
·fill material,
·daily cover material at landfills,
·aggregate or filler in concrete, brick, or block manufacturing.

Mono Screw Pump Working Principle and Apllication

M ono screw pump , also called  sewage pump  or  progressive cavity pump ,  belongs to the rotor type positive displacement pump .   M ono screw pump  is depend ing  on the screw meshing with liner on the discharge and suction cavity to conveying liquid volume change.   It is a kind of method of pressurized screw pump, a main working parts by bushing has a double helix cavity (stator) and the stator cavity and its meshing singlehead screw screw (rotor).   When the input shaft through the universal joint drive making planets revolving around the center of the stator, rotor stator, rotor, vice is continuous mesh form sealed cavity, the seal chamber volume invariably uniform axial movement, the medium from the suction end of deputy to the stator, rotor pressure side, the suction medium sealed cavity through the stator without stirring and destruction. M ono screw pump  is an ideal pump used to feed drilling fluids to ...

Drilling Waste Management Solutions

With the increasing attention to environmental protection, drilling waste randomly disposal has been seriously forbid by many countries. Considering the global need of such kind of equipment need, KOSUN  focused on drilling waste management solutions for many years. Contamination of drilling fluids  with drilled cuttings is an unavoidable consequence of successful drilling operations. If the  drilling fluid  does not carry cuttings and caving  to the surface, the rig is not either “making hole” or soon will be stuck in the hole it is making. The drill cuttings that are separated from the drilling fluid on the surface by the so lid s control equipment and some quantity of unrecoverable or economically unwanted drilling fluid are a major source of drilling waste. Drilled and formation solids that are sized smaller than can be removed by the solids control equipment are often reported as drill solids. Some quantity of drill s...

Shale Shaker Screens Types and Application

S hale shakers typically consist of wire mesh  shaker screens  in various mesh sizes that shake or vibrate the drill cuttings which across and off the shaker screens as the drilling fluid or drilling mud flows through shaker screen s  and back into the drilling mud system.  There are mainly three types of shaker screens for different types of shale shakers, like PWP screen, PMD screen, and hook strip screen. PMD screens are Derrick ’ s patented products for Derrick 2000 series and Derrick 500 series shale shakers . While PWP and hook strip screens are widely used for world famous shale shakers like brand M-I SWACO, Derrick, Brandt and KOSUN. Hook strip s creen s  is a  common kind of s hale s haker s   s creen, which can be widely used in different conditions in drilling operation. This screen is constructed with two  or three layers of stainless steel wire cloths bonded to a steel...
