Drilling Waste Treatment of Pit Less Mud System by Kosun

Drilling Waste Treatment

Drilling waste  treatment  of pit Less Mud system,  is a very important thing that is required to maintain is a proper integration between the drilling waste management system and solid maintaining process.

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 shale shakers .
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.

When the drilling waste cuttings are taken out from shell shaker, 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.

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.

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 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

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.

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.

What Are Drilling Waste?

Drilling Waste

Every process that is initiated has its outcomes. Oil drilling basically involves boring into the ground and penetrating rock by use of specially designed tools. During drilling, the rotary drill bit grinds downwards penetrating layers of rock. In the process, large rocks cuttings that have been broken up result. These rock cuttings are called drill cuttings. The process of drilling, separating and directing drilling fluid to the down-hole creates drill cuttings which are drilling waste.

However, drilling waste are not limited to drill cuttings alone. They involve

•    Muds that have been so degraded that they can no longer be rejuvenated by recycling, but need to be disposed of.
•    Mud that is discarded or spilled.
•    Solid laden wet mud and cuttings that have been separated from the drilling fluid without having been recycled and are not useful for recycling.
•    Solids that are removed by centrifuges from the mud stream.

Synthetic Based Muds (SBM) drill cleaner holes with minimal sloughing and produce less drill cuttings thereby generating less waste unlike the Water Base Muds (WBM). Most of the Oil Based Muds (OBM) and SBM are recycled and therefore minimize drilling fluid which reduces waste.

Wastage is a normal consequence of the drilling process. Drilling involves extracting the desired end product from a mass of other unwanted products such as sand, silt, fibres, drill cuttings and mud. Because the process involves drilling fluid and mud, the mass of waste is usually a wet mixture. If these unwanted products mix with the drilling fluid they will contaminate it and bring the process to nothing at inception. The use of Solid Based Mud (SBM) and Oil Based Mud (OBM) is recommended because they are less pollutant than the Water Based Mud (WBM) which cannot be recycled. It is important that companies adhere to the regulations governing drilling waste management.
