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.

KOSUN’s drilling waste treatment system has been successfully put into operation in many well sites

KOSUN Machinery’s drilling waste treatment system with vertical cuttings dryer as the core equipment has been successfully put into operation in many well sites at home and abroad.

“Drilling mud zero discharge” refers to the traditional drilling waste treatment method. In the previous traditional drilling process, the drilling waste was disposed of by establishing a mud pit at the drilling site, that is, the drilling waste was discharged. To the mud pit on the ground for the next step of processing, or even directly buried. However, this traditional discharge method has caused serious pollution and great harm to the environment and human life.

Therefore, the State Environmental Protection Administration of China formally legislated in January 2015 to put forward stricter processing requirements and standards for drilling waste. The concept of “drilling mud zero discharge” also came into being. At present, KOSUN Machinery is using the vertical cuttings dryer as the core equipment for the Drilling waste treatment system while drilling has been successfully put into operation in many well sites at home and abroad.

Present Situation and New Technology of Drilling Waste Treatment

Drilling waste is a byproduct of drilling operations in the oil and gas industry. It is composed of various materials, including rock cuttings, drilling mud, and produced water. Proper disposal of drilling waste is important for the protection of the environment and human health. In recent years, new technologies for drilling waste treatment have emerged, improving the efficiency and sustainability of waste management practices.

1, Present Situation of Drilling Waste Treatment

Traditionally, drilling waste has been disposed of in landfills or pits. These disposal methods pose environmental risks, as they can contaminate groundwater and soil. Additionally, they require large amounts of land and can be expensive. As a result, the industry has been moving towards more sustainable and cost-effective waste management practices.

One common method of drilling waste treatment is thermal desorption. This process involves heating the waste to high temperatures to vaporize the hydrocarbons, which can then be collected and reused. Another method is bioremediation, where microorganisms are used to break down the organic materials in the waste. This method is more sustainable, as it produces less waste and can be more cost-effective.

2, New Technology of Drilling Waste Treatment

Newer technologies have been developed to improve the efficiency and sustainability of drilling waste treatment. One such technology is the use of electrokinetics. This method involves applying an electric current to the waste, which causes the contaminants to migrate to a collection point. The contaminants can then be removed and disposed of safely.

Another technology is the use of supercritical water oxidation. This process involves heating the waste to high temperatures and pressures in the presence of oxygen. This breaks down the organic materials in the waste and produces water and carbon dioxide as byproducts. This method is more sustainable than thermal desorption, as it does not require the use of fossil fuels to power the heating process.

Nanotechnology is also being explored as a potential solution for drilling waste treatment. Nanoparticles can be used to remove contaminants from the waste through adsorption, which is the process of attracting and holding onto molecules. This method has the potential to be more efficient and cost-effective than traditional treatment methods.

Finally, the use of artificial intelligence (AI) is being explored to improve the efficiency of drilling waste treatment. AI can be used to analyze data and optimize treatment processes, resulting in improved treatment efficiency and reduced costs.

3, Conclusion:

The drilling industry has been moving towards more sustainable and cost-effective waste management practices in recent years. Traditional disposal methods, such as landfills and pits, are being replaced by newer technologies that are more efficient and environmentally friendly. Technologies such as thermal desorption, bioremediation, electrokinetics, supercritical water oxidation, nanotechnology, and AI are being explored as potential solutions for drilling waste treatment. As these technologies continue to develop and become more widely adopted, the environmental impact of drilling operations can be reduced, contributing to a more sustainable future.

Measures for Drilling Waste Treatment in Sichuan Oil and Gas Fields

Sichuan Oil and Gas Field is an oil and gas production area centered on the Sichuan Basin in Southwest China. With 125 existing gas fields and 12 oil fields, it is the largest natural gas industrial base in the country and the first natural gas production area in China with a natural gas output exceeding 10 billion yuan. Sichuan oil and gas field is a large gas field in the country. If the drilling waste is not effectively treated, it will cause serious environmental pollution problems.

The waste of drilling waste treatment in Sichuan oil and gas field is mainly for the treatment of various pollutants such as waste liquid, cuttings, waste gas and mud generated in the drilling process. The purpose of processing drilling waste is to finally turn the drilling waste into treasure, that is, water can be recycled and solid waste can be used reasonably.

Disposal method of drilling waste in Sichuan oil and gas field: First, in the solid-liquid separation stage, the mud and sand are treated with a mud shaker, a sand pump, a desander, and a desilter, and then the mud is stored in a mud tank for drying. The equipment generally used for waste drying treatment includes: screw conveyor, drill cuttings dryer, screw pump, and centrifuge equipment.

Drilling mud recycling: The treated mud can be reused, and the dried waste residue can be used in construction projects such as brick making or road paving. The treatment of oil and gas field drilling waste through the above process not only achieves the purpose of environmental protection and harmlessness, but also enables the waste to be used economically and rationally, achieving the dual goals of environmental protection and energy saving.

KOSUN Comprehensive Drilling Waste Treatment Solution

Solid-liquid separation is an important part of the drilling waste treatment process. The smaller the proportion of the water content in the waste, the smaller the volume of the remaining solids, and the smaller the required treatment cost, which can effectively control the treatment cost and reflect economic benefits. In recent years, domestically developed orifice plate filter presses, filter belt dewatering conveyors, horizontal screw centrifuges and other dewatering devices have promoted the improvement of drilling waste treatment technology.

This kind of treatment route is to let the sewage pond that collects wastes settle naturally first , and perform conventional sewage treatment on the free water produced after natural settlement; at the same time, add flocculants and coagulants to the sludge part for chemical destabilization treatment, and then pass it through dewatering devices such as centrifuges, filter belt dehydrators, orifice plate filter presses further separate solids and liquids, and finally solidify and treat the separated solids and moisture respectively, thereby completing the elimination of drilling and completion waste fluids. Harmful treatment. In this scheme, since the dehydration device is still in the trial stage, the degree of automation is not high and the efficiency is low.

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.

The Following information is more about Kosun drilling waste treatment equipment

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.

-DC Series Decanter Centrifuge is used in separating suspension of solids phase with particle ≥2μm in diameter for drilling mud and fluids handling.

-Screw Pump is an ideal pump used to feed drilling fluids to decanter centrifuge since drilling fluids is pushed to proceed along axial direction evenly. Therefore, the inner flow speed is kept low, volume unchanged and pressure stable so that vortex and agitation are prevented. Screw Pump is useful for wet mud drilling mud waste management and cuttings transportation.

Screw conveyor (Auger) can be used in drilling waste management projects, providing an effective and low-cost drilling cuttings transport system for offshore and onshore drilling rigs. Adopting a multi-sectional composite structure with each section of 12 feet (3.66m), the screw conveyor can be flexibly assembled on different drilling sites, with characteristics of simple operation, stable structure, strong adaptability and high safety, significantly improving the operating efficiency of equipment and reducing the cost and resources.

Drilling Waste Cuttings Treatment of Pit Less Mud System

Drilling Waste

Drilling waste cuttings treatment of Pit Less Mud Systems are also known as closed loop systems. In this closed loop systems solid control equipment are used to minimize the wastage of natural oils used in drilling. The solid control equipment that are used in pit less mud system are:

1) Shale Shaker :
This is the first equipment in solid control equipment for drilling waste cutting. It consists of s screen that does the work of separating the solid and liquid from the mixture. The screen comprises of mesh clot that is attached to a frame using tension. This is usually used for separating very large solids from the liquid. The slurry that is obtained is stored into a tank and then again sent for further filtering to a mud cleaner.

2) Mud Cleaner :
A mud cleaner combines two processes of desanders and desilters. Here they use a device that separates sand and silt particles from the drilling fluid. As these sand particles are fine, they cannot be removed by a shale shaker. Desander is used for removing solids that are abrasive in nature and dedilters are used to remove silts. The resultant mixture is then sent to a Decanter centrifuge.

3) Decanter Centrifuge  :
It is a fast rotating device that uses centrifugal force and sedimentation principle to remove the solid particles from the drilling fluid. Here the machine is rotated very fast so that the solid which is of high density is forced to go out and the liquid which is of less density is forced to go at the center.

After the mixture is separated, the drilling fluid that is obtained can be reused as a drilling fluid. This not only saves the cost but also helps to prevent the wastage of our limited natural resource.

Also the solid that are obtained are first dried before disposing them or resuing thwm for some special purposes.
Thus some part of the drilling waste cuttings is reused and some part of it properly disposed in an ecofriendly manner.

Drilling Waste Treatment Importance Equipment from Kosun

Drilling Waste treatment

Drilling Waste Treatment Equipment With the development of the oil industry, the pollution problems caused by drilling are also getting more and more attention.

China’s oil field per year only drilling production of waste drilling fluid produced about more than 900,000 cubic meters, of which one-third of the discharge to the environment, the environment and stratigraphy have caused varying degrees of pollution. Drilling pollution is mainly based on waste drilling fluid and waste water pollution.

Drilling produces waste, including waste drilling fluids, diamond cuttings with drilling fluids, simply a mixture, such as excess cement, isolation fluids and other fluids. The amount of drilling waste is determined by a number of factors including the size of the wellbore, the efficiency of the solid-controlled equipment, the solid-phase capacity of the drilling fluid, the ability of the drilling fluid to inhibit the dispersion of the cuttings, and the amount of drilling fluid remaining on the cuttings.

drilling waste treatment

The percentage of solid phase in the waste drilling fluid varies from 50% to 25% of the maximum. There is always a certain amount of drilling fluid with the cuttings together with the waste, no matter how good the solid control equipment, drilling fluid can not be separated from the cuttings. If these effluents are discharged, they will cause significant pollution to the environment.
Abandoned drilling mud pollution of the environment, in essence, waste drilling mud in the liquid phase of the environment pollution, vertical cutting,liquid reuse as a resource recycling as an important means of waste disposal.

In response to this issue, Tsunami Oil conducted a three-year repeated research and experiment, through a different treatment process, successively in Xinjiang Tarim Oilfield, Daqing Oilfield and other drilling waste management equipment on-site construction, Solid phase to meet the national requirements of the emission standards, most of the liquid phase as a slurry base for the re-use of resources, only a small amount of liquid after the depth of treatment after the standard discharge or re-injection.

A large extent to reduce the production costs of drilling fluid, but also to achieve the energy-saving emission reduction, the purpose of safety and environmental protection.
