Abstract:
A recovery system comprising:a recovery apparatus comprising a recovery tank having a cavity and a base presenting an inclined surface to said cavity, said recovery tank having at least one inlet and at least one outlet, said recovery apparatus having a least one agitation system for creating a force within said cavity of said recovery tank to assist in the separation of the components of a solid particulate material/drilled solids mixture; a manifold hydrocyclone system coupled to the at least one outlet; at least one recovery shaker, coupled to the manifold hydrocyclone system, and having at least one screen; and at least one shale shaker having at least one screen with varying screen sizes, said manifold hydrocyclone system being situated on said shale shaker;wherein a mixture of solid particulate material, drilling fluids, thin particles of drilled solids and drilled solids enters said shale shaker and drilled solids are separated from the mixture using said screen of said shale shaker, the remaining mixture then entering said recovery tank and being further separated by the force created by said agitation system, the remaining mixture of the particulate material, drilling fluids and fine particles of drilled solids are transferred to said manifold hydrocyclone system wherein the fine particles of drilled solids are separated from the remaining mixture using the centrifugal force created by said hydrocyclone system, the mixture then entering said recovery shaker wherein the drilling fluid is separated from the solid particulate materials.
