• Gumbo Boxes

    The gumbo chain is positioned directly after the mud/gas separator at the flowline and is the first piece of BRANDT solids control equipment to mechanically remove solids from the mud.

     

    Description

    IMPROVING SOLIDS CONTROL EFFICIENCY BY EFFECTIVELY REMOVING GUMBO AND OTHER STICKY CLAYS BEFORE REACHING DOWNSTREAM SOLIDS CONTROL EQUIPMENT 

    Gumbo boxes are the first step in effective solids control when large, sticky, hydrated clays (gumbo) and other troublesome solids are encountered during drilling. Gumbo boxes use a motorized chain conveyor to remove problematic solids before they reach the shale shakers. The removal of gumbo and other solids by these units allow the downstream solids control equipment to  operate much more efficiently.

    A cartridge assembly houses the gumbo chain(s) or scalper(s) that convey the solids to be discharged. Gumbo boxes are available in three configurations:

    • 5 foot (1.5 meter) single cartridge

    • 6 foot (1.8 meter) single cartridge

    • 6 foot (1.8 meter) dual cartridge

    The gumbo chain utilizes larger hole openings than a scalper belt. Optimum chain opening sizes can vary depending on the formation drilled and the needs of the drilling program. The gumbo box is available in single or dual cartridge units that can be installed on nearly any rig. Contact your NOV sales representative for more information.
