• KING COBRA™ Shaker

    The BRANDT™ KING COBRA Shaker utilizes four pretension screens and linear motion to remove detrimental drilled solids from the mud system.

     

    Description

    COMBINING ECONOMICAL DESIGN AND RUGGED, DEPENDABLE PERFORMANCE WITH INCREASED SCREENING AREA

    The BRANDT KING COBRA Shaker utilizes four pretension screens and linear motion to remove detrimental drilled solids from the mud system. This allows the KING COBRA to minimize mud losses while enhancing cuttings dryness. Maintenance on the KING COBRA is minimal and only a small inventory of replacement parts is necessary to sustain optimal operation. Additionally, the shaker's rugged design offers years of reliable operation.  

    A variety of starter options are available that allow users to configure the shaker(s) to best suit their needs.

    VFD G-Force Controller

    OPTIMIZED SEPARATION EFFICIENCY THROUGH FLEXIBILITY, HIGH PERFORMANCE AND EASY OPERATION
    The Variable Frequency Drive (VFD) G-Force Controller affords customers the opportunity to manage shale shaker performance and screen life based on cuttings loading. By selecting one of the three settings (NORM, HIGH or MAX), operators are able to manage light to heavy cuttings loading on the shaker bed while reducing screen usage. The VFD utilized is simple, rugged and capable of being outfitted to new, or retrofitted to existing, KING COBRA, KING COBRA Plus and LCM-3D shale shakers.

    Each of the three settings change the G-forces generated on the shaker bed. When drilling the top hole section with fast penetration rates (maximum screen loading), the MAX setting should be selected to efficiently remove solids from the drilling fluid (mud). In the intermediate hole section, the HIGH setting should be employed, while in the slow-drilling, bottom hole section, the NORM setting should be utilized.

    Settings may be adjusted while the shaker is in operation, thus giving the user the flexibility to adapt to changing drilling conditions without interrupting operations. This provides the operator more control over shaker performance and screen life. Varying the G-forces exerted on the shaker bed allows screen life to be extended by reducing the G’s as hole size and solids loading lessen.
