An open loop drilling beads recovery system comprising: a fluid inlet in fluid communication with a shale shaker having at least one screen adapted for the separation of solid particulate material present in a used drilling fluid; said shale shaker being in fluid communication with a well rig tank; a fluid outlet in fluid communication with a manifold hydrocyclone system; a first and a second pump; said first pump being in fluid communication with the bead catch tank and the manifold hydrocyclone system, and said second pump being in fluid communication with the well rig tank and the bead catch tank; where, in operation, a used drilling fluid containing drilling beads enters the system through the inlet and is directed to said shale shaker for separating a mixture of solid particulate material, drilling fluids, thin particles of drilled solids and drilled solids from the drilling fluid; the resulting fluid enters the bead catch tank; said second pump pumping clean drilling fluid from the well rig mud tank to the bead catch tank; the fluid in the bead catch tank is pumped by said first pump to a manifold hydrocyclone system where fine particles of drilled solids are separated from the remaining mixture using the centrifugal force created by said hydrocyclone system; and said remaining fluid containing the drilling beads exiting said manifold hydrocyclone system back to the well rig mud tank through the fluid outlet. |
