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.
Mud Cleaning System
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.

An oil base fluid can be defined as a drilling fluid which has oil as its continuous or external phase and the water, if present, is the dispersed or internal phase. The solids in an oil base fluid are oil wet, all additives are oil dispersible and the filtrate of the mud is oil. The water, if present, is emulsified in the oil phase.

There are several operational indicators and trends from the mud engineer’s daily mud checks and a few special tests that can be used to identify water wetting of oil-mud solids before the problem becomes serious and irreversible.

Oil-based mud is a drilling fluid used in drilling engineering. It is composed of oil as the continuous phase and water as the dispersed phase in conjunction with emulsifiers, wetting agents and gellants. The oil base can be diesel, kerosene, fueloil, selected crude oil or mineral oil. –wiki
