How To Effectively Deal With Drilling Waste?

How to effectively deal with drilling waste?KOSUN gives you the answer!

Drilling waste/mud is one of the major sources of pollution in the oil and gas industry. Due to engineering requirements, drilling mud is often mixed with substances such as oil, water, and organic clays. In recent years, the use of oil-based mud, water-based mud, and composite-based mud has increased, leading to escalating costs and environmental pollution issues.

The emergence of mud treatment systems has successfully addressed the challenge of inefficient and environmentally friendly treatment of drilling waste. The main processing process of Xi’an KOSUN’s drilling waste treatment system refers to the harmless treatment of drilling waste from the wellhead before landing. The waste mud in the waste mud pool can also be diluted and then classified and utilized for treatment, realizing the mobilization of drilling environmental protection devices. Mud that has been effectively treated can be reused, reducing frictional resistance, lowering accident rates, and improving wellbore quality.

Drilling cuttings treatment method:

Different from traditional methods, the mud system transforms the treatment of waste mud from “end-of-pipe treatment” to “whole-process control”. The waste mud is diluted, coagulated, and separated into cuttings, mud cakes, and water. Solid substances in the mud are treated through washing, coagulation separation, and chemical reaction to meet discharge standards. Harmful substances and chloride ions in the mud are dissolved into the water, which is then dehydrated into mud cakes by vacuum adsorption or squeezing. Meanwhile, the centrifugally separated wastewater undergoes concentration treatment through flotation sedimentation, filtration systems, and reverse osmosis systems. The treated wastewater meeting standards can be reused for drilling circulation.

Steps for drilling mud waste treatment:

Waste materials separated from drilling waste, such as cuttings, can be purified, dried, and recycled as concrete materials.

The mud water produced from washing cuttings can be chemically treated, destabilized, coagulated, and separated into mud cakes, which can be mixed with clay or shale in proportion for brick making.

The separated filtrate undergoes pretreatment processes such as destabilization, coagulation, flotation, oxidation, and adsorption filtration to remove major pollutants. It can be used for oilfield reinjection, safe strata reinjection, or discharged up to standards. After treatment by the sewage treatment system, wastewater can achieve standard discharge.

Considerations for drilling mud waste treatment:

Xi’an KOSUN’s drilling waste treatment system is the only environmentally friendly device in China that truly achieves harmless and green treatment of drilling waste mud, combining the most advanced mud purification and drying treatment technology at home and abroad, and after three years of research and multiple improvements and upgrades. The use of the mud treatment system eliminates the need to transport solid waste from the wellsite for centralized treatment, saving transportation costs and processing space, and making environmental protection efforts more effective.

Drilling fluid vibrating screen is a solid control equipment in drilling mud solid phase control system

Xi ‘an KOSUN oil solid control drilling fluid vibrating screen is the primary solid control equipment in the drilling mud solid phase control system. It separates a large amount of drilling cuttings carried by the mud from the well sheet so that the mud can enter the secondary separation equipment. The screen can be used alone, or can be used in double or multiple pairs.

Xi ‘an KOSUN oil solid control drilling fluid vibrating screen is a high frequency linear vibration machine, it is equipped with three screen frames and two vibration motors, and has the characteristics of manual adjustment of screen frame angle (AWD) during drilling, LS583 vibrating screen can be operated between -1° and +5° adjustment screen frame angle. Thanks to structural design innovations, drilling fluid shakers can efficiently separate cuttings. The vibration motor is fixed to the screen frame with a high-strength support beam and positioned on the screen bed. By positioning the vibration motor in this way, the vibration force (G-force) can be directly applied to the screen. The vibration isolation device can protect the base frame from the vibration of the screen frame. The mud is fed through the feed box into the shaker.

The main components of Xi ‘an KOSUN oil solid control drilling fluid vibrating screen include screen frame, vibration motor, screen tensioning system, AWD Angle adjustment system, locking device, feed box, electrical system, etc.

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.

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.
