Drilling Fluid Management & Disposal
Drilling fluid waste management and solids control of drilling mud related technical and developed situation.
Nine distinct mud systems are defined here. The first seven are water-based, while the eighth is oil-based. The ninth category is a specialized one in which air or gas is the continuous fluid. The 9 categories are:

The Mud tanks system consists of equipment on board that contributes to the storage, mixing, circulation and purification of drilling fluid. Drilling fluid is very expensive and large volumes are used in connection with drilling a well. It is therefore desirable to reuse drilling mud.
The mud tank system removes drilling cuttings that come up from the hole along with the drilling mud so that the cleaned mud can be returned to the well. If the mud does not have the proper properties in relation to the well, it can result in major damage to the well and the drilling equipment. After the cleaning process, the drilling mud is carefully checked to make sure that the cleaning system has done a satisfactory job.

Overall what is required is a mud system that gives the lowest overall cost of drilling each hole section, except for through the reservoir. The direct cost of the fluid itself (the cost per barrel of mud) is but one component of this overall cost. If serious hole problems occur because the mud was not optimized for the formations in an effort to “save money,” obviously much more money will be spent than would have been saved on the mud bill.
