Abstract: A method for removing solids submerged in a polymer-based slurry. The present invention filters used polymer-based slurries, containing solids, to return the slurry to a condition that is favorable to the owner. The method utilizes a first collection tank, an agitator, a shaker with a plurality of screens, a desander, a desilter, a centrifuge that removes solids down to a size range of 5-7 microns, and a second collection tank. Each component can be used in tandem depending on the polymer-based slurry characteristics that are required by the owner. The preferred embodiment includes the following steps: obtaining used polymer-based slurry, pumping the slurry into a first collection tank where the slurry undergoes agitation, pumping the slurry through a plurality of screens, pumping the slurry into a desander and/or a desilter, passing the slurry through a screen, and pumping the slurry in centrifuge that removes solids down to a size range of 5-7 microns.

Abstract: A system for processing solid and liquid waste includes a first shale shaker, a second shale shaker, a submersible pump, a centrifugal pump, a first collection tank, a second collection tank, a mud cleaner assembly, a variable frequency drive (VFD) centrifugal solid-liquid separator, and a water clarifying assembly. The first shale shaker is in fluid communication with the second shale shaker through the submersible pump. The second shale shaker is in fluid communication with the centrifugal pump through the first collection tank. The centrifugal pump is in fluid communication with the mud cleaner assembly. The mud cleaner assembly is in fluid communication with the VFD centrifugal solid-liquid separator through the water clarifying assembly. Resultantly, the system discharges a flow of usable water through the VFD centrifugal solid-liquid separator as an initial load of solid and liquid waste is inputted into the first shale shaker.

Abstract: A mixture suitable for use in a drilling fluid includes an amount base fluid and recycled fuel oil in an amount sufficient to provide an emulsion stability of the drilling fluid of about 500 volts or greater.
