Drilling Waste Management Company-Kosun

Drilling waste management is the name of a major headache for the companies involved in drilling in different gas and oil mines. Due to the increased awareness of people regarding environment, drilling companies have to perform an extensive procedure before disposing the drilling waste. It is a very complex process in which the intervention of the professionals is required. So, drilling companies must seek the expertise help from a waste management engineer in order to ensure the proper disposal of shale shaker generated waste without disturbing the environment.

Drilling waste management entails all processes and precautions required or recommended to ensure a safe environment. Drilling waste contains spent fluids and drilling cuttings that result from the drilling process. The spent fluids and drilling cuttings that are referred to as drilling waste have no use in the ensuing drilling process therefore must be disposed of. However the disposal of this waste requires that the set environmental management standards and regulations are adhered to for the maintenance of a safe environment and also in order to avoid legal disputes and penalties.

The newest drilling waste treatment equipment-Kosun

The main components of the drilling waste(drilling waste treatment) are cuttings, excess drilling fluids, hydrocarbons and water and are mostly categorized as hazardous waste.The disposal of these wastes are, in most locations around the world, highly regulated. The solids in the drill cuttings are usually separated and the cleaned off drill mud residue, as well as the produced water are usually cleaned at considerable costs.

drilling waste treatment equipment

The first step in managing drilling wastes is to separate the solid cuttings from the liquid drilling mud. Once solid and liquid drilling wastes have been separated, companies can use a variety of technologies and practices to manage the wastes. For some applications, drilling wastes are solidified or stabilized prior to their ultimate management practice. The management technologies and practices can be grouped into three major categories: waste minimization, recycle/reuse, and disposal.

Vertical Cuttings Dryer( Vertical Centrifuge)  can perform solid/liquid separation through centrifugal separation. The vertical cuttings dryer can effectively recover the liquid phase in drilling cuttings, making the solid phase become very dry. It is suitable for water-base mud, oil-base mud and synthetic base mud. By recovering the mud in drilling cuttings, the vertical cuttings dryer can reduce the drilling cost and cut down environmental pollution. With handling capacity of 40-60 T/h, the oil on cuttings (OOC) of drilling cuttings can be reduced to lower than 5% (w/w) after treatment, meeting the international emissions standards and environmental protection requirements. The vertical centrifuge can also be applicable for drilling waste management in onshore and offshore drilling.

Hi-G Dryer is used to recover the mud from drilling cuttings,so as to reduce the liquid/oil content in drilling cuttings to as low as about 10%(w/w) and recover part of the drilling mud,so that the drilling cost can be reduced and the drilling waste volume can be cut down,for the purpose of reducing environmental pollution.The Hi-G dryer suitable for both of WBM and OBM.

The Work Principle of Decanter Centrifuge

The work principle of decanter centrifuge:Centrifuges, like shale shakers and hydrocyclones, are solids control equipment, It achieves the separation goal by dividing the fluid into highdensity and lowdensity streams to separate one from the other. The processing is achieved by accelerated sedimentation. As the drilling fluid passing through a rapidly rotating bowl, centrifugal force moves the heavier particles to the bowl wall, where they are scraped toward the underflow discharge ports by a concentric auger, also called a scroll or conveyor, which rotates at a slightly slower rate than the bowl. The separation of the heavier particles divides the processed fluid into two streams: the heavy phase, also called the underflow or cake; and the lighter phase, which is called the overflow, light slurry or centrate. The heavy phase will be discarded while the lighter one will be returned to the mud tank to be further treated. The removal of these solids in order to control rheology and filter cake quality is the primary reason for centrifuging weighted drilling fluids. When the finest solids are not removed, the only alternative means of reducing their concentration is dilution, always an expensive process.

Before hydrocyclones (desanders and desilters) and decanter centrifuge became available for drilling applications, shale shakers and dilution were the only means of solids control of drilling fluids. Consequently, solids too fine to be separated by the shaker screens in use could be controlled only by dilution which was a costly procedure that generated large quantities of excess drilling fluid. Decanter centrifuge was designed to remove the fine cut and at the same time reduce the drilling cost.

To meet the requirements of the development of modern drilling engineering, KOSUN developed and equipped with the explosionproof variable frequency control system which could adjust separation factor and drum rotational speed.By this new technology,make the centrifuge to adapt property changing of mud duringthe operation process,that make the treatment more effective and perfect.

Common Troubleshooting of Decanter Centrifuge

Solids control equipment in one of the indispensable mud sand pump equipment used in the process,Desander Hydrocyclone will encounter some of the problems of how we want to troubleshoot it?( Decanter Centrifuge Troubleshooting)

If worn, then Desander Hydrocyclone may be the following two questions:

The first packing (packing) seal leakage serious, packing heavy wear, surface wear sleeve.

Remedy: Remove the packing (packing), with a 90 ° bend thin wire inserted into the cartridge mechanical seals, Oilfield Drilling Mud Decanter Centrifuge is bushings moving wall, if the check of Oilfield Drilling Mud Decanter Centrifuge is to be too deep for-sleeve trench filler cap too tight will lead to severe wear fillers.

Second, DWM Solids Control of polyurethane seals wear serious cause leakage.

Remedy: Replace polyurethane seal (Normally, when the sand pump is running 3-6 months, Drilling Mud Cleaner should be replaced at once polyurethane seals and seal sleeve).

There must be an electrical engineer specializing in operation and maintenance. At present, only a few well-drilling operations abroad with the type of high-speed centrifuge, high performance requirements for drilling special wells, Drilling Mud Cleaner recommended speed centrifuges and centrifuge series of domestic high-speed process, the medium-speed centrifuge drilling into the post-processing of high-speed centrifuge for liquid storage, treatment by high-speed centrifuges, Drilling Fluids Desander used repeatedly into the circulatory system. Drilling Fluids Desander at this time to get a better purification of positive significance to improve the follow-up equipment of DWM Solids Control (drilling sand pump, drilling, downhole equipment, etc.) of the life-saving mud material consumption, improve ROP and other aspects in Dwm control.

The Component of the Solid Control System

Solid control system is also called drilling fluids purification system, primarily applied for solids control and solid-fluid separation in drilling fluids so that the drilling mud might be recycled. Consisted of 3-7 module composite tanks and configured with 4 phases of purification equipment, it is fit for 2000-7000 meter oil drilling processes. The whole system is innovative with the bottoms of its purification tanks made to be conical and its edges equipped with mud agitating system to prevent solids from depositing. Besides, its tanks and bins may be comparted or united depending on the demands of drilling processes. Each of them is connected to another via pipe network in which the valves at the bottom of suction pipes are flexible while being opened, but can turn to be a good seal when closed.

The Component of the  Solid Control System:

Solid control system

The first main equipment for solid control system should be the vacuum degasser,We could analytics from the function of vacuum degasser. Generally speaking, horizontal vacuum degasser will be used to separate the gas from the drilling solids. What’s the reason to do like that? Because we should do everything to prevent any dangerous elements in oil & gas drilling fields. That’s why we should put the vacuum degasser as the first role.

The second one should be mud cleaner. KOSUN MD Series Mud Cleaner is the second stage separation equipment for drilling fluids, which deals with the mud being treated by the first grade separation equipment. The barite will be recovered and cuttings which are bigger than barite will be removed. Then the barite in the underflow will flow into circulation tanks through the screens when the weighted mud passes while the particles that are bigger than mesh will be removed.

The third equipment, we think it should be shale shaker (with necessary steel frame shaker screen). Actually, after the drilling solids have been transported and fed into vacuum degasser and mud cleaner, the third step is going with shale shaker. Commonly, we still need to be transported the solids onto the shale shaker, or we could say onto the surface of shaker screen. The equipment of transporting we should use is centrifugal sand pump or screw pump; and we may use shear pump to cut the drilling solids into small one if they are in big size. With the different design of the shaker screen’s mesh, we could get the drilling solids separated in different sizes.

The fourth equipment should be the decanter centrifuge. KOSUN DC Series Decanter Centrifuge is used to separate suspended solids ≥2μm in diameter and treat the drilling mud and fluids. It is especially effective when used in oilfield service industry, industrial service industry and especially in environmentally sensitive areas. This type of centrifuge is high in recovery rate, effective in solids control and remarkable in the reduction of cost spent on drilling mud resupplying and management. It is a very sophisticated dynamic balancing machine, able to operate stably with the whirling speed ranging from 0 to 3900 and generate centrifugal force of 3000G. In solid control system, decanter centrifuge has been popularly used, which is also the popular one for drilling waste management. In this step, we could not only get the result of separating, but also we could separate the oil from the drilling solids, even if the oil is just a little part.

Of course, the whole equipment must be mounted on the top of drilling mud tank, which is a kind of basic equipment for both solid control system and drilling waste management (vertical cutting dryer is the core equipment for this system), but it is a kind of powerful equipment.

Drilling Waste Management System – Containment and Handling

Drilling Waste Management

Drilling waste management  is more and more important. The necessity of energy is increasing relentlessly. People are becoming more and more power hungry. With the increase in the demand, drilling companies are trying to cope up with the ever increasing demand by setting up new drilling sites.

A major issue that any drilling company has to handle is how to manage the drilling wastes generated from shale shaker cuttings. Drilling waste management companies are trying to sort out the most environment friendly method for the waste management.

Drilling Waste Management Plan
Drilling Waste Management Plan

A major step of drilling waste management plan is managing the containment of the wastes generated by shale shaker. A discussion about the issue is given below.

How the drilling waste is contained and handled: The first issue that should be consider in containing and handling drilling waste is the geographical features of the certain drilling sites.

Containment and handling of drilling wastes are no longer to simply on shore based as more and more companies are engaging in off shore drilling for new source of oil and gas. The most common way of managing shale shaker generated drilling wastes is building and using sumps.

Different types of drilling wastes including cement returns drilling wasted and drilling cuttings are contained in a sump. The sumps that are used to contain drilling wastes should not be built in non – polluted area of surface.

A sump inspection must be performed by experts right before the waste disposed in it. A waste tracking system for the drilling wastes must be developed to control the flow of wastes in the sumps.

A regular and efficient inspection schedule must be maintained by the employees in order to ensure that waste contamination sumps are in subtle condition. Another important issue for handling and contamination of drilling waste is decommissioning the sumps. When any sump is decommissioned, drilling authority must ensure that there is zero possibility of further contamination.

How to Optimize the Performance – Drilling Waste Decanter Centrifuge

Drilling Waste

A centrifuge is a device that works on the concept of centrifugal force. The centrifuge makes an object rotate around its own fixed axis, making a circular motion at a very high speed. A decanter centrifuge does the work of separating the mixture of solid and liquid in industries.

In a decanter centrifuge , when the mixture if fed, the centrifuge is rotated at a very high speed. As the centrifuge spins in a circular motion, perpendicular force is exerted on the mixture. This causes the denser substance in the mixture to move out in a radial direction, that is, towards the surface of imaginary circle, while the substance that is less dense moves inside radially, that is at the center.

In drilling  waste management in industries, this process helps in separating solids from liquids like oil, so that the oil can be recycled and reused, thus protecting our precious natural oils.
As a decanter centrifuge is used in many industries like Food Processing industries, oil industries, waste water treatment plants and chemical industries , it is very important to optimize its performance so that there is minimum wastage and maximum efficiency.

Criteria for improved performance of drilling waste decanter centrifuge:
    Before feeding the mixture to the decanter centrifuges , the mixture should preferably fed to a shale shaker. This shale shaker will separate big solids from the mixture. Then the resulting mixture must be fed to the decanter for further filtration. This will reduce the wear and tear of the decanter.
    Right amount of centrifugal force must be applied.
    The Speed of the decanter must be optimal so that the solids in the mixture are safely transported out of the machine.
    The decanter centrifuge is prone to abrasion as the solids in the mixture may rub against the walls of the device. So proper care must be taken by using abrasion resistant material especially at the input zone and at the solid output zone.

Drilling Waste Cuttings Treatment – Pit Less Mud System

Drilling Waste

Oil and gas drilling is one of the most prolific business now a days. A very complex mechanism is used to drill oil and gas from the mine. A very common equipment that is seen in oil and gas drilling area is a shale shaker.

There are two basic approaches of drilling using a shale shaker .
The first one is the solid control system which is very popular for drilling now a days.
The second approach is the pit less mud system for drilling. Today the focus will be given on the pit less mud system for drilling.

What is pit less mud system for drilling: The pit less mud system for drilling is basically a process in which no pit is dug on the surface while for collecting cuttings from drilling.

In pit less mud system for  drilling waste cuttings treatment , a very important thing that is required to maintain is a proper integration between the waste management system and solid maintaining process. When the waste cuttings are taken out from shale shakers , two particular equipments named G force drying shaker and vertical cutting dryer are used to extract the liquid and to make the cuttings drier.

After that, the dry cuttings are transported from the shale shaker unit to the disposal unit. In that stage, the waste cuttings can be disposed on the surface without digging any pit. In many oil and gas drilling sites, a more environment friendly approach is taken to dispose drilling waste cuttings.

In that case, the drilling waste cuttings are taken to another unit for the final processing. In this unit, the waste cuttings are processed via solidification process. Waste cuttings can also be processed by thermal desorption machine. Thus, the drilling waste cuttings become contamination free and environment friendly. Then, the waste cuttings can be disposed without any fear.

Drilling Mud Waste Management System of Kosun Strategies

Drilling Mud Waste Management

Drilling Mud Waste management is one of the major concerns for the drilling companies all around the world. It is simply impossible to avoid pollution while shale shaker perform drilling. The main sources of drilling waste are the fluid removed drilling cuttings that are cut by the shale shaker.

Drilling companies are undergoing through an extensive pressure from various environment activists all around the world. So, an environment friendly waste management system is a prime requirement for the drilling companies. Several waste management strategies are taken into action for different types of waste while drilling. Here is a discussion about different types of drilling waste management strategies.

Different approaches for waste management: In order to manage the waste of a drilling site, the first step is to set up necessary solid control equipment like shale shaker. Till now the most popular drilling waste management strategy that is used is dilution. In the dilution process for controlling solids, a certain amount of fluid is extracted from the cuttings and are gathered into a pit. The rest of the cuttings are transformed into a concentrated solid after another extraction of fluid is executed to those by adding any liquid like water or oil.

After this, the drilling wastes become ready to be disposed. In the next step, it is imperative to determine the surface area and the amount of waste that is required to handle. While disposing the wastes, drilling companies can use G force drying shaker to make the wastes radiation and contamination free. Another consideration in drilling waste management is managing the cement returns.

Sometimes cement returns are simply disposed by following the mix bury cover system. In this process, the drilling waste with cement returns is gathered altogether and transformed into hard cement pit. Then, the hard pits of cement returns are grinded into small pieces. After that, the grinded cement pits can be disposed. The whole process of management must not take more than a year.
