Drilling Waste Management of Kosun Solid Control

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.

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.
