In the field of oil & gas drilling, drilling fluid is used to aid the drilling of boreholes into the earth. Drilling fluids carries the rock excavated by the drill bit up to the surface. Its ability to do so depends on cutting size, shape, and density, and speed of fluid traveling up the well ( annular velocity ). These considerations are analogous to the ability of a stream to carry sediment; large sand grains in a slow-moving stream settle to the stream bed, while small sand grains in a fast-moving stream are carried along with the water. The mud viscosity is another important property, as cuttings will settle to the bottom of the well if the viscosity is too low.

Oil Drilling Spot
Why is drilling mud with low solids applied in oil drilling? Let's have a acquaintance with its benefits.
1. Increased drilling penetration
2. Increased service life of bit or back reamer
3. Reduced mud cost
4. Reduced triplex mud pump, mud motor & surface equipment maintenance cost.
5. Reduced clean up & haul off or disposal cost
These benefits are the result of planning prior to boring and are accomplished through the use of properly designed, sized and operated solids removal equipment. It is the responsibility of the boring crew to become knowledgeable in the proper use of the equipment; otherwise the potential benefits may be reduced or nullified.
Methods of Controlling Solids in the Drilling Fluid
1. Mechanical treatment
2. Chemical treatment
3. Dilution of mud with water
4. Discard mud & mix new mud.
Effective solids control can be attributed to the overall performance of all the components of the mud systems. Conditioning the drilling fluid with the goal of dramatically lowering maintenance cost, avoiding excessive chemical treatment and maintaining mud systems volume will decrease the chance of equipment failure, unnecessary high mud costs, hole and drilling problems. Shale shaker is a quite right solids control equipment for drilling fluid processing system.
