Drilling Fluid Management & Disposal
Drilling fluid waste management and solids control of drilling mud related technical and developed situation.
A drilling fluid recycling system to remove solids from the drilling fluid so that the fluid can be re-used, a guidance system to accurately guide boring operations. All equipment shall be in good and safe operating condition with sufficient supplies, materials and spare parts on hand to maintain the system in good working order for the duration of the project.

A hydrocyclone which main part of desander and desilter is a device used to sort, classify, and separate a liquid suspension(solids) system into solids and liquid. Hydrocyclones have a wide variety of applications in many industries, particularly in oilfield application processing. The hydrocyclone is a continuously operating classification device with no moving parts. It utilizes fluid pressure to cause rotational forces that accelerate the settling of particles according to their size, shape and density.

Hydrocyclones, commonly referred to as cyclones, have been extensively utilized in the classification of particles in comminution circuits. The practical range of classification for cyclones is 15 microns to 400 microns. Cyclones are used in secondary equipment of mud separating circuits as well as mud cleaner or desander.

Drilling fluid maintenance costs can decrease greatly when proper solids control techniques are utilized. From a fluid control standpoint, it would be desirable in most cases to remove all drilled solids. Although this is possible with the use of chemical enhancement prior to separation, it is not always the most economical approach. The goal of a solids control system is to achieve the balance between mechanical solids separation and dilution that will result in drill solids being maintained at an acceptable level with the minimum cost.
