Drilling waste management manufacturer – Kosun, from China, are searching drilling mud treatment and disposal methods for 25 years, manufacturing quality drilling cuttings waste management system and serving the clients around the world.
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.
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.
