Drilling mud (drilling fluids) is used to Remove cuttings from well; Suspend and release cuttings; Control formation pressures; Seal permeable formations; Maintain wellbore stability; Minimizing formation damage; Cool, lubricate; and support the bit and drilling assembly; Transmit hydraulic energy to tools and bit; Ensure adequate formation evaluation; Control corrosion (in acceptable level); Facilitate cementing and completion.drilling fluids(drilling mud) is pumped from the surface through the hollow drill string, exits through nozzles in the drill bit, and returns to the surface through the annular space between the drill string and the walls of the hole.

The drill bit grinds rocks into drill cuttings, which are entrained in the mud flow and are carried out to the surface. And we separated the mud from the solids to make the mud return to the recirculating mud system. Continue reading “Oil Mud Separation”
