Analysis of Drilling Waste Management Market

Drilling waste management activities are a critical constituent of successful drilling and production operation. Suitable application of waste management principles is essential for efficient drilling operations and environmental protection. During drilling, the largest potential waste stream includes used drilling fluids and cuttings that are produced while drilling the well.

Drilling processes in the oil & gas industry usually generate two primary types of wastes, namely drill cuttings, and used drilling fluids. Most of these wastes associated with oil & gas drilling activities can cause significant hazards to the environment. Hence, to minimize the impact on the environment, these wastes need to be effectively treated and disposed. Universally, countries have employed various regulatory measures to tackle this challenge. The methods used to store, mix-bury-cover, land-spread, and biodegrade drilling waste require extensive drilling waste management information system and significant land disturbance, and licensees using these methods are required to reclaim affected sites.

As reports show, the global drilling waste management market by the intensity of drilling activities and the regional governmental policies over waste disposal. It highlights some of the key industrial issues and market impulse factors. It also describes some of the important dynamics such as driver, restraints, and opportunities.

Working Principle of Drilling Waste Treatment Equipment

How to make use of drilling mud to meet the purpose of safe production, environmental protection, as well as economical and effective application has been a major subject of drilling production.

The working principle of drilling waste treatment equipment
Abandoned drilling mud from the mouth of the well directly access to the device. And through its sealing strip type pipe, screw conveyor transfers waste drilling mud into cuttings dryer. Then the screen mesh by high-speed rotating and filter by cutting dryer, then the vast majority of the dry cutting slips down by another screw conveyor and discharged from the first mouth exit. The remaining liquid mud is fed into the centrifuge by feed pump and is processed again. Then the separated drilling cuttings will eventually be fine cuttings and is isolated from the second sand mouth. At the same time, the treated sludge by reinjection pipelines to the mud tank is recycled again.


With the enhancement of environmental consciousness. Nowadays many more environmental regulations limiting or banning the discharge of various types of drilling fluids and associated drill cuttings globally. The drilling contractors started to utilize "zero discharge" or "ship to shore" drilling operations. In these operations, drill cuttings and associated waste fluids are collected on the rig in cutting boxes and then sent back to shore for disposal or treatment prior to disposal. Even when the discharge of drill cuttings offshore is still allowed. there is often now a requirement to collect and transport drill cuttings on the rig for secondary process such as vertical cutting dryer that will reduce the volume of drilling fluids associated with cuttings prior to discharge. In the drilling waste management or some similar works, screw conveyor or auger is a necessary part to convey materials from base ground to a higher position for further treatment.

Screw conveyer, commonly known as auger. It has horizontal, inclined and combined form, and it can be used with other transport devices, to accomplish combined transport, separate transport, mixing, blending, dehydration, compounding, discharging and stacking, etc. KOSUN Screw Conveyer is used in the drilling waste management for the drilling fluids or cuttings transportation.

Tips for KOSUN Mud Agitator installation

Drilling mud agitator, as a tank equipment in drilling solids control system consists of reducer and explosion-proof electric motor, has got dominant application in mud mixing and concoction. It is easy to keep up, and suitable to operate in terrible outdoor working conditions. Its large agitating strength can extend to a large scale of drilling fluids and greatly reduce resisting moments when it starts. The plate surrounded by blades prevent solids from gathering together around lower blades, reduce resisting moments against blades and avoid burning the electric motor during overload start up process.


Mud agitator is consist of electrical motor, reducer, shaft & impeller. The driving motor & reducer box are mounted on the agitator base, while the shaft inserts into the mud tank, and the impellers which normally have three or four blades are equipped at the other end of the shaft. When the impellers rotate by the electrical motor, the drilling fluids would also move. This mechanical driving agitator has good performance in big & deep mud tank. But the disadvantage of this agitator is that there would exist some bland area that agitator can not move the fluids in these areas.

KOSUN Mud Agitator installation
1. Make certain the mounts in which the agitator will rest upon are heavy and secure enought to support the weight and torque of the agitator.
2. The agitator base is mounted and secured with four bolts, nuts and lock washers, the impeller shaft should now coupled to the gearbox shaft.
3. Check the electric motor for proper voltage wiring, the KOSUN mud agitators are wired 380 and 460 voltage unless specified.
4. The impeller should rotated clockwise when viewed from the top, if the rotation is incorrect, switch any two lead wires at the starter to reverse the rotation.
5. Check the oil level, oil should be filled to the bottom edge of oil level plug using the lubricant specification.

China KOSUN serves the oil & gas drilling industry for 20 years since its establishment in 1992 with horizontally mounted mud agitators which then are mounted on the top of mud tank. As we discussed previously that the mud agitator belongs to mechanical agitation, the purpose of which are to agitate the drilling fluids in the compartments of mud tank. Different type of drilling fluids would requires different horsepower of motors, as well as speed reduce ratio. Another key point is to decide the length of the shaft, and also the type of impellers. All of these depends on the drilling fluids property & mud tank dimension.

KOSUN Hi-G shaker for Drilling Waste Management System

KOSUN Hi-G shaker recovers drill fluids cuttings from water-based and oil-based drilling fluids, can make the proportion of the liquid phase in the drilling to below 10%, can significantly reduce the cost of the waste discharge, and is particularly effective in the oil base mud cuttings.


It mud be noted that until the advent of KOSUN Hi G technology, the traditional method for control of OOC was install a cuttings wash/cleaning system. This was not only an expensive solution. But in some cases a very inefficient one, which sometimes reported higher figures than that being discarded from the shaker. As it is, the Hi-G dryer requires minimal supervision. Together with its low operation costs and significant savings in fluid, it is an attractive alternative to any cuttings cleaning system. It can also be utilized well with high cost “pseudo” mud and/or “closed loop” systems.

Another major benefit of the Hi G dryer technology, sometimes overlooked, is the elimination of whole mud losses from the shaker. This historically has ensured that the shakers were never run at their optimum capacity and thus the solids control system efficiency was adversely affected. Incorporating the Hi G dryer down steam allows the shakers to be run close to maximum capacity without the concern of whole mud losses.

Hi-G Dryer is also called Hi-G shaker as it is one kind of shale shaker which is as drilling mud solids control equipment. But Hi-G dryer is used to treat drilling waste in drilling fluid processing system.

Solutions to Prevent Mud Lost of Oilfeild Drilling Mud Shale Shaker

Drilling mud is a kind of colloidal suspension composed of clay, water, oil and chemical mixture which is mainly applied in oil or gas drilling plant. Many solids particles with its diameter blew 2 microns in the drilling mud.

Thus, shale shaker is widely used in the solids phase separation from liquids material. In particular, drilling fluids shale shaker is naturally used in oil or gas drilling fields. This essay will mainly discuss the ordinary faults of shale shaker and solutions to overcome these faults in the process of oil and gas driSlling. 

Mud lost has been the headache problem in the process of shale shaker for oil drilling industries, which is common problem but difficult to avoid during the drilling production.


Causes of drilling mud lost in drilling mud shale shaker porcessing 
In most case, there are the following three causes resulting in mud lost
1. Material problems
 
High viscosity of the drilling mud, high proportion of solid phase particles or dispersive drilling cuttings
2. Screen machine problems.

Low vibration of shale shaker, high number of screen mesh and small screening area 
3. Assembly problems. In appropriate installation of the feed inlet of shale shaker.

Solutions to resolve the problem
According to the above simple analysis, we can find that the reasons for mud lost is multiple and next we will focus on the solutions to resolve this problem. However, we should exclude faults in accordance with the following steps.
1.Check whether the shaker screen mesh is fit for the shale shaker or not.
2.Check if drilling mud property matches the drilling condition.
3.Check if the rotation direction of the motor is correct. 
4.Check whether the amplitude of the shale shaker is low or not.
5.Check whether the flowing direction of the drilling mud is correct or not.
