In its pristine state, drilling mud may contain two types of solids – bentonite providing viscosity and, optionally, barite for weight. The bentonite particles range in size up to 10 microns. The barite ranges from 5 to 80 microns, with … Read the rest
Modern, linear motion shale shakers are the most significant advance in solids removal technology. They permit the use of much finer screens than had been used in the past. By reducing the quantity of material to be removed by … Read the rest
Hydrocyclone is core part of mud cleaner (desilter, desander). Hydrocyclones are a cost-effective method of removing many of the fine solids missed by the shaker in unweighted muds.
Hydrocyclones separate solids from fluid by using centrifugal force to cause solids … Read the rest
Mud cleaning unit also called mud cleaner, which to control solids in drilling process. Mud cleaning is well-suited to types of mud as follows.
The most familiar combination separator is the Mud Cleaner or Mud Conditioner (Figure 1). In many cases, combinations of vibratory screening and settling/centrifugal force are used together to provide an effective separation.
Mud cleaners were developed in the early 1970s … Read the rest
