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.

Drilling waste mud treatment is currently a major problem in oil fields

Waste drilling mud is one of the main pollution sources in the oil and gas industry, and its waste disposal is currently a major problem that plagues oil fields.

The oilfield drilling waste mud treatment process is the immediate disposal of waste drilling mud (drill cuttings) while drilling, meeting the requirement of “mud zero discharge”, reducing land use and reducing environmental pollution. This technology is to change the “end treatment” to “full process control”, the waste mud is diluted-flocculated-separated into three parts: cuttings, mud cake and water, and the solids in the mud are treated by water washing, flocculation separation and chemical reaction. Make the cuttings and mud cake meet the discharge standard. After the harmful components and chloride ions in the mud are separated into the water, they are dehydrated by vacuum adsorption or extrusion to make mud cakes. At the same time, the waste water separated by centrifugation is subjected to air flotation. The sedimentation, filtration system, and reverse osmosis system are used for concentration treatment. After treatment, the up-to-standard wastewater can be reused for drilling recycling.

The main equipment for the treatment process of waste oil drilling mud includes: drying shale shaker, drill cuttings dryer, drilling fluid centrifuge, screw conveyor, screw pump, etc. KOSUN’s mud zero discharge system can effectively control the water content of drilling cuttings (6%-10%) in the drilling mud, stabilize the liquid phase performance, and achieve the purpose of zero discharge of the mud.

There are many kinds of waste mud treatment processes in oilfield drilling. Each treatment solution needs to be determined according to the drilling site and drilling construction conditions. It must not only achieve the treatment effect, but also meet the national environmental protection requirements, and strive to achieve harmless treatment. It plays an active role in improving and protecting the environment, soil and groundwater.

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.

Therefore, to improve efficiency, it is necessary to reduce from the source, and to simultaneously treat waste during the drilling process. After fully drawing on some advanced foreign experience, combined with the on-site situation of the drilling site in the country. KOSUN, a manufacturer of oil drilling equipment and solids control equipment, has formulated a comprehensive drilling waste treatment solution for customers. The program starts from the source through four major steps of solids control equipment-dehydration/water treatment/water recycling/filtering-mud recovery-solidification/biodegradation/thermal analysis/drill cuttings reinjection.

How to deal with drilling waste at the well site with natural radiation?

KOSUN is a professional manufacturer in drilling waste management. KOSUN has many years of drilling waste management experience. It can provide supporting and efficient oilfield drilling waste mud treatment equipment for different types of waste drilling fluids, especially for waste oil-based mud and waste water-based mud. With rich experience in treatment, we can also provide professional drilling solid waste treatment equipment.

There are two main aspects of the impact of radioactive materials on people: one is that the radioactive material emits rays, it will not directly contact the body, as long as the distance is sufficient, it will generally not cause harm to the body. On the other hand, radioactive pollutants are in direct contact with the body, which is a great harm. We must be very careful to avoid contact with these pollutants as much as possible, so as not to cause unnecessary harm, but also as much as possible to avoid pollution and harm to the environment.

Natural radioactive materials can be treated by appropriate methods, by injecting waste into blocked or abandoned wells, and ensure that the water level is below the groundwater level; or discharge into the ocean after meeting the requirements of relevant environmental protection laws and regulations; or transform it within the allowable content of the environment, and stored in a specially designated place for storing natural radioactive waste; it can even be discharged into an isolated and non-evaporable pool. In order to better solve the problem of radioactive waste disposal and reduce disposal costs. Where radioactive sources are found, the equipment and tools used will also be contaminated by radioactive waste. Therefore, they must be properly handled to prevent secondary pollution.
