How to Conduct a Shale Shaker Performance Audit

Conducting a shale shaker performance audit is a critical process for ensuring optimal solids control and drilling fluid management on any rig site. A thorough audit helps identify inefficiencies, prevent costly downtime, and extend the life of both the shaker and downstream equipment. By systematically evaluating key operational parameters, drilling teams can maximize separation efficiency, reduce waste, and maintain a cleaner, more effective drilling fluid system.

Key Parameters to Measure and Monitor

The foundation of any audit is accurate data collection. Begin by verifying the shaker’s screen condition, ensuring there are no tears or blinding. Check the screen tension to manufacturer specifications, as loose screens drastically reduce performance. Next, measure the flow rate and rheological properties of the drilling fluid entering the shaker, including viscosity and solids content. The G-force of the shaker’s vibration motors is another crucial metric that must be confirmed to be within the optimal range for the specific screen mesh and fluid properties being processed.

Assessing Fluid and Solids Handling

Observe the fluid flow pattern across the screen deck. The drilling fluid should form a thin, even layer, allowing for maximum exposure of the fluid to the screen surface. Look for signs of flooding, where fluid bypasses the screening process, or signs of overly dry cuttings, which can indicate excessive G-force or improper screen selection. The audit should also quantify the amount of liquid retained on the discharged cuttings, as this directly impacts drilling fluid losses and environmental disposal costs.

Implementing Corrective Actions

Based on the audit findings, implement corrective measures. This may involve changing to a finer or coarser screen mesh, adjusting the shaker’s deck angle, or recalibrating the vibration motors. Proper feed and distribution of the drilling fluid onto the screen is also vital; ensure the flow is centered and not eroding a single spot on the screen. Regular audits create a feedback loop for continuous improvement in your solids control system.
