Drilling Waste Disposal-Burial in Oil & Gas Industry

Burial is the most common onshore disposal technique used for disposing of drilling wastes (mud and cuttings). Generally, the solids are buried in the same pit (the reserve pit) used for collection and temporary storage of the drilling wastes mud and cuttings after the liquid is allowed to evaporate. Pit burial is a low-cost, low-tech method that does not require drilling wastes to be transported away from the well site, and, therefore, is very attractive to many operators.

Burial is the placement of waste in man-made or natural excavations, such as pits or landfills.

Burial may be the most misunderstood or misapplied disposal technique. Simply pushing the walls of the reserve pit over the drilling cuttings is generally not acceptable. The depth or placement of the burial cell is important. A moisture content limit should be established on the buried drilling cuttings, and the chemical composition should be determined. Onsite pit burial may not be a good choice for drilling wastes that contain high concentrations of oil, salt, biologically available metals, industrial chemicals, and other materials with harmful components that could migrate from the pit and contaminate usable water resources.

In some oil field areas, large landfills are operated to dispose of oil field drilling wastes from multiple wells. Burial usually results in anaerobic conditions, which limits any further degradation when compared with drilling wastes that are land-farmed or land-spread, where aerobic conditions predominate.

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...
