GN’s mud system is not only used in oil gas drilling but also in some other drilling projects. Therefore, GN developed the drilling mud recycling system for non-oil drilling like HDD, CBM and water well drilling.
One type of water well drilling is for the drilling water, while the other one type of water well drilling is for water re-injection to underground for keeping the pressure of oil layer for continuous oil producing.
Working principle of the mud recycling system for water well drilling is same as the mud system for oil gas drilling. Removing the cuttings, sand and silt in the drilling fluids to make the drilling fluids reusable is the purpose of the mud recycling system.

Compact Mud System

Shale shaker is always the first stage equipment for solids control; it could remove the coarse cuttings in the drilling fluids. Shale shaker is the only one equipment by separating the solids hundred percent by the size of the particles. The screen could remove out the solid particles larger than the wire mesh openings. By adjusting the G force and the shaker deck angle, the operator could adjust the dryness of the discharged solids.
De-sander and de-silter could be called hydrocyclone unit. Same as the decanter centrifuge, hydrocyclone separates solid and liquid by using centrifugal force. Density difference is the main factor should be considered if the hydrocyclone unit would be applied.
Mud system for water well drilling is designed compact structure. As per the treating capacity, the corresponding equipment with same capacity would be installed in the system. For different drilling depth, the nos. of the mud tanks are various in different mud system.
Not all the shale shaker, de-sander or de-silter would be used in one mud system. GN ever made a mud recycling for a water well drilling project. The main equipment includes shale shaker and de-silter unit, no de-sander involved as the de-silter cyclone could fully hold function of the de-sander unit.
Besides mud recycling system for water well drilling, GN also developed other separation solutions. Any question, please contact with GN freely.
