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.

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.

Cuttings dryer is a core equipment in drilling waste management because it enhances environmental protection. Designated to meet the strict environmental conditions and guidelines imposed on disposal of cuttings and work site, it utilizes high-speed decanter centrifuge which optimizes liquid and solid separation in high volume processing.

The cutting dryer has the following characteristics
•    Rational structure built into the bedplate that adjusts and balances the distribution of vibrating motion.
•    Enhanced protection of spare parts with wear proof measures which include use of stainless steel for mesh screen and spiral scraper to guarantee long service life.
•    The torque sensor which helps regulate the motor in case of overload in operation thus ensuring reliable operation.
•    Viewports on cone header and bedplate making it easy and convenient to inspect and maintain the screen mesh and spiral scraper.
•    The equipment uses centralized lubrication station which facilitates ease of flow of lubricant to machine parts and reduces damage due to poor lubrication.

The cutting dryer is a welcome and indispensable aspect of  waste management, designed with respect to maintaining a safe environment.

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 Management

Drilling Waste Management functions involves the various procedures of collection, containment and handling of the waste followed by a proper method for its disposal.

Drilling waste is the byproduct or unwanted matter generated as a result of drilling activities done for the extraction of precious fuels. Gas and oil are the most common products obtained from drilling and the byproducts include both of solid and fluid nature.

However, it is not the nature of the waste that worries us, but the effect it has on our environment and Mother Nature. So scientists have classified these wastes into two categories, acceptable and non acceptable.

This helps us identify each type of drilling waste and how dangerous it can turn out to be is not properly managed and disposed. Thus the importance of drilling waste management and drilling waste disposal method is an idea that is of very high relevance to the present era.

A successful drilling operation requires this aspect to be well taken care of. As a result, many private and public organizations undertaking these activities have turned to green and eco friendly means for making the activity a more sustainable and conservative one. Today there are several effective methods for proper waste disposal which are also put to best use.

Drilling waste management system involves with below products: Vertical Cuttings Dryer( Vertical Centrifuge), D Series Decanter Centrifuge , Screw Pump ……

The drilling waste generated as a result of all these activities are first separated from the desired quantity of matter by suitable methods. Conventional processes like settling and filtering where used for quite a long time since its introduction. But with advancements in technology, the facilities will also improve and this resulted in yet another technique that takes care of this separation procedure mechanically.

This separated waste is isolated and stored in some proper tanks and is later transported for proper disposal. Drilling waste is sometimes converted into more useful products. Agricultural fertilizers is an example for such a product.

Drilling Waste Treatment Methods from Kosun

Drilling Waste Treatment  Methods

Drilling waste Treatment methods plan a very important for environment protection.

Drilling waste management system including a trailer having at least one centrifuge and a solids catch tank receiving solids.

An effective drilling waste management is an essential characteristic of a successful drilling operation. The very process of drilling oil and gas does in fact generate large quantities of spent muds and drill cuttings. And this quantity is no negligible amount.

According to a study conducted way back in 1995, an estimated quantity of 150 million barrels or drilling waste was generated in American soil alone. This gives us a brief idea about the total waste generated by these activities which in turn stresses the importance or need for an effective management and handling system for this waste.

Drilling waste treatment methods

Drilling waste generated in the process is broadly classified into two: drill fluids and drill vertical cuttings . Drill fluids also known as muds, are used to facilitate the smooth functioning of these equipments and is separated in the final stages. These wastes are separated by mechanical means and some effective techniques have been developed by scientists over the century.

Quite recently did scientists develop the effective solid removal system, which is mechanical in its functioning. Before its introduction there were methods like dilution which involved transferring the whole matter into a waste pit. In the waste pit, the matter is diluted to facilitate easy separation of the unwanted and desired materials.

Other method used for managing or disposing of drilling waste  , mainly solid waste is through the conventional method of settling. The solid is allowed to settle to the bottom of a specialized tank like structure. From this, the settled particles are removed deliberately by one way or the other.

There are many other methods as well for waste management and removal, but the most commonly used is the one with mechanical removing technique. The waste removed by these methods is later contained in some tank like structure. After suitable means of management and containment, it is then disposed properly with no harm done to anyone.

Drilling Waste Management, Drilling Waste Disposal Options

Drilling Waste Management

Drilling waste management is a vast and systematic process. After shale shaker extracts drilling cuttings from the mines and after the extraction of fluids from the cuttings, whatever is left is considered as drilling wastes . These wastes are required to be decontaminated by processing the wastes in various equipments.

After all the processing, the most important issue needs to be handled regarding drilling waste management. The issue is determining the waste disposal option. It is the end stage of the total drilling waste management. An environment friendly waste disposal method must be followed in order to calm down all the controversy and criticism regarding environmental sustainability.

Here a brief discussion about the drilling waste disposal options is given below.
How the drilling waste should be disposed? A very common disposal method of drilling waste is land spray while drilling. In this method, the drilling waste is sprayed by using a pump. This method of disposal is very effective for fluid based drilling waste.  It is very cost effective.

Another effective way of disposing drilling waste is pumping off the waste. In this process, the non – radioactive clear fluid of waste is pumped in a green planting area. It is very sustainable way of disposal as it ensures the best use of natural elements. Another vastly used approach for waste disposition is the mix – bury approach. In this method, a mixture is created by using drilling waste with mud of disposing area. Above the mixture of those two components, a single layer of soil is used to cover the mixture.

It is also a very environment friendly way of waste disposition as it causes minimum contamination. Finally, another way of disposing the drilling waste is using separate waste disposal sumps. In this method, several waste sumps are built for disposing different types of waste. It is the formal waste disposal system of drilling companies.

Drilling Waste Management Of Oil and Gas Handbook

Drilling Waste Management

Drilling waste management is one of the most frequent duties that should be performed in any drilling area. A skilled management system must be developed for the drilling waste management.

If any drilling company fails to perform certain sustainable procedure while drilling waste, it is certain to face the eye of the storm for the lack of competency in managing drilling waste.  So, in order to solve this problem, a very approach has been taken by the drillers all around the world.

drilling waste management system

They have developed a certain agenda of fundamental procedure for drilling and disposing the drilling waste in an environment friendly way. This is called the oil and gas handbook for drilling waste management. Now, here is a brief discussion about the handbook of drilling waste management is given below.

The handbook of drilling waste management: According to the handbook in order to manage shale shaker generated oil and gas drilling waste, the construction and functioning of any commercial offshore waste management site, an application should be placed in front of the Environmental Bureau and to the oil conservation division.

A drilling company must confirm a financial assurance before establishing any waste management and disposal site in the area. Surface waste management facilities must only handle the non – intoxicating waste so that it can’t cause any environmental degradation.

There should be different approaches for managing different kinds of waste depending on their contaminating and radio activity level. The professionals that are responsible for managing the drilling waste must be certified and well trained. Drilling sites must not expose any intoxicating waste to the environment in any circumstance. After gathering waste from shale shaker, shaker screen there should be a proper and an extensive procedure to decontaminate the drilling waste right before the disposal.

Finally, the handbook for waste management provides the necessary and valuable guideline to the drillers for a sustainable waste management.

Some the standard rules that must be adopted to minimize waste are:
1] Drilling Waste Containment:
•    The waste obtained from drilling must be properly contained either in a sump (earthen hole) or good quality tanks.
•    There must be proper record of how the drilling waste is stored and how is it disposed.
•    It must not be mixed with other wastes.

2] Suitable Disposal Sites:
•    The site where the waste is doing to be disposed must suitable and must not cause pollution.
•    The suitability of the sites is soil is assessed and its salinity is measured.
•    Any toxic waste cannot be disposed. These types of wastes needs to be treated.
•    There are many reasons that can make the waste toxic, like, corrosion inhibitors, emulsifiers, lubricants, de foaming agents and even some type of bacteria.

3] Disposal Methods:
•    There are many ways of disposing the waste of different kind.
•    For water based mud systems, there are disposal options such as on- site disposal options and off-site disposal options.

4] Wastes from pipelines:
•    When drilling a pipeline for fresh water or drilling a freshwater well, the drilling waste that is obtained here can be managed in many ways like, storage pits where pits are formed in soils and other off-site disposal options such as land spraying and land spraying while drilling.


We are looking forward to cooperation with you.
