The process of drilling fluid recycling system

Drilling fluids recycling system or solids control system, is the process of cleaning used drilling fluids in a closed loop style of drilling operation. The drilling fluid is pumped from the entry pit to a mud recycling system or solids control unit .

The mud recycling system cleans the drilling fluid in the following stages.

Firstly the fluid is pumped up from the entry pit using the sand guzzler pick up pump to a dump tube and over the first sizing screen removing any of the larger cuttings bought back from down the bore hole.

The drilling fluid and smaller size solids pass through the screen and into the tank. Then the fluid is sucked into the sand trap and into the sand pump which pumps the fluid through the desander cones. These desander cones are designed to removed solids larger then 20 micron through centrifugal force.

The larger size solids are dumped out of the bottom of the cones and the cleaner fluid passes through the top of the sand cones and back into the tank ready for use.

When the fluid has passed through the various cleaning stages it is clean enough to be used again by the drilling unit and the process starts over again in a continuous loop.

Mud recycling is the preferred method when large volumes of drilling fluids are required and or access to water is restricted or limited.
