What is Important Equipment in Drilling Waste Management?

Drilling Waste management

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 drilling waste treatment 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.

Drilling waste management  system therefore is concerned with using materials, substances and facilities in the drilling process that minimize  drilling waste while at the same time employ proper disposal of waste in a manner that reduces toxicity.

Drilling fluids and cuttings are emitted during drilling. According to the American Petroleum Institute estimates that only 1995, the United States onshore drilling to produce about 150 million bbl drilling waste, so the drilling waste recycling is urgent need nowadays.

In order to minimize drilling waste , the use of environmentally friendly tertiary waste treatment methods:
(1) adjust the drilling process or use the appropriate drilling fluid, so that the waste generated by the drilling process at least;
(2) will have been reduced to Minimum drilling waste is recycled as much as possible; and
(3) Drilling waste treatment  that can not be recycled by lawful meant.

1. Use synthetic base drilling fluid
The new synthetic base drilling fluid has the drilling characteristics of oil-based mud, but does not contain polycyclic aromatic hydrocarbons, but also has low toxicity, faster biodegradability and low bioaccumulation. Will not bring great environmental impact to the seabed. Compared with water-based mud, synthetic mud makes the wellbore cleaner and more stable, resulting in fewer cuttings and can be recycled, usually water-based mud cuttings directly into the sea.

2.Drilling fluid recycling
Will be used oil-based mud and water-based mud recycling, to minimize the amount of drilling waste emissions.

3. Treatment of drilling waste
Conventional land-based drilling waste is treated by first extracting the liquid portion of the slurry pool and then landing or dispersing the remaining solid material in situ. In oil and gas production areas, oilfield waste is dedicated to landfills; other areas will meet the emission standards of drilling waste transported to urban or industrial waste landfill. Another approach is to recycle the waste into the formation through the drilling annulus, including pouring the effluent into the formation fractures at a pressure above the formation fracture pressure or pouring the effluent into the formation at a pressure below the formation fracture pressure Natural cracks and salt holes.

Oil and gas industry has made great progress in environmental protection, there are a variety of drilling waste disposal methods, operators can be in accordance with the relevant legal requirements, cost and environmental requirements to choose the most appropriate drilling dirt treatment methods. New drilling waste disposal methods are being studied to meet future environmental requirements.

Drilling Waste Treatment

Drilling waste treatment more and more get recognized and popoular in industry.

Over the past few decades, the oil and gas industry has taken various measures to minimize the waste generated by drilling in order to better protect the environment and public safety.

Drilling operators use environmentally friendly tertiary waste treatment methods to deal with drilling waste:
in the first stage, the operator adjusts the drilling process or displaces the appropriate drilling fluid to minimize the waste generated during the drilling process. This is both for the operator to reduce the cost of dirt treatment, but also more conducive to environmental protection.
The second stage, will have been reduced to a low limit of drilling waste as much as possible recycling.
The third level, through a legitimate way to deal with can not be recycled drilling waste.

Offshore drilling waste treatment   is limited to emissions, re-injection or return to shore.

In contrast, land operators have a large range of options in dealing with drilling fluids. Usually onshore drilling waste in situ; on the offshore platform, most of the water-based mud and cuttings and synthetic slurry are poured into the sea; some land drilling waste is transported to commercial waste disposal outside the well site And offshore oil-based mud and cuttings must be returned to shore or re-injected into the ground at the well site.

At present, drilling companies are studying new drilling fluids for different stratigraphic conditions. The new drilling fluid not only has the proper drilling characteristics, but also contains less harmful additives that inhibit vegetation growth.

The use of new, more environmentally friendly additives in place of important components in drilling fluids, such as the use of ilmenite powder instead of barite powder as a mud aggravating agent, can reduce the impact on the environment.
Current drilling fluid heat treatment costs are high, and not suitable for offshore use. The future may improve the drilling fluid heat recovery drilling waste treatment technology, reduce processing costs, improve the organic lye recovery rate. The new approach will improve safety and effectiveness and make it suitable for offshore drilling platforms.

Drilling waste water is one of the main pollution sources of oil exploration enterprises. In the process of drilling, the treatment measures and effects of drilling wastewater are directly related to whether the drilling technology is reasonable in technology and economy, and it is also a major problem to avoid the impact on the surrounding agriculture, animal husbandry and fishery.

Waste water treatment process of new ideas, the development of new wastewater treatment process is a new process of environmental protection workers in the oil industry’s top priority.

Most of the major domestic oilfield treatment of drilling waste water using chemical coagulation treatment after discharge. Because coagulation can only remove the colloidal or suspended particulate contaminants in the water, and little effect on some of the mud treatment agents that have already formed the solution. This is also the main problem with the use of chemical coagulation methods to deal with the existence of drilling wastewater.

Drilling waste management , the current can not be separated from the chemical coagulation of this part of the successful development of drilling wastewater treatment of pharmaceuticals, is the key to solve the treatment of drilling wastewater. Chemical coagulation is the traditional process of drilling wastewater treatment.

Drilling wastewater treatment process has not been a new breakthrough, to explore the new drilling wastewater treatment process is another study of drilling wastewater treatment. Biological purification drilling waste water with its very low cost, easy management and other advantages to become a promising approach.

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.

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.

Drilling Waste Management

In the process of drilling a water or oil hole, the solids that are obtained and the drilling fluid get mixed. This is called drilling waste. This waste must first be separated for proper management.

After separation of the mixture, the drilling fluid that is obtained can be reused. But for the solids that are obtained, proper measures need to be taken so that there is minimum wastage and no harm is caused to the environment.

The first step is to take care that the waste which is generated is as minimum as possible. This can be done by slightly changing the way, the hole is drilled. That is instead of conventional drilling other drillings options must be considered like;
1] Directional Drilling: Here instead of going directly vertical, drilling is done by taking angles while going down. Its variations are extended reach drilling, horizontal drilling and multiple laterals.
2] Drilling holes with small diameter: Technologies used to obtain holes with smaller diameter are slim hole drilling and coiled tubing drilling.
3] Techniques in which less drilling fluid is required like pneumatic drilling.

The second step is to use those fluids that does not harm our environment. Examples of such fluids are Synthetic Based muds (SBM) that biodegradable, does not accumulate and digs clean holes and has almost no toxicity.

Third is that, the wastes that are obtained must be reused as much as possible. The fluid that is obtained can be reused again as a drilling fluid. The solid cuttings that are obtained can be reused by spreading it on road and preventing road erosion or using it as a construction material.

Lastly, proper care must be taken for those solids that cannot be used and needs to be disposed. For pits may be build or may be dumped as landfills, where another layer of soil or other material.
The advantages of Drilling waste management are:
•    It is good for the environment and saves energy.
•    It reduces the cost of operation as we get to reuse the materials.
