The number of shale shaker units needed on a drilling rig depends on the maximum mud circulation rate, the capacity of individual shakers, and whether operational redundancy is required. Aipu provides shakers sized to meet any rig configuration from single units to multi-shaker tandems.
Sizing: Capacity Determines Count
Start with the rig maximum circulation rate and add a 25 to 50 percent safety margin. Divide this total required capacity by the capacity of the shaker model being considered to determine the minimum number needed. For a rig circulating 180 cubic meters per hour with 50 percent margin, the required capacity is 270 cubic meters per hour. Using Aipu Hunter-MG5 shakers at 180 cubic meters per hour each, two units would be needed. Using Hunter-MG4D double-deck shakers at 280 cubic meters per hour, a single unit could suffice.
Redundancy Considerations
Many drilling contractors specify at least two shakers even when one could handle the flow rate, providing operational redundancy. If one shaker requires maintenance or screen changes, the other continues operating at reduced throughput, preventing a complete shutdown of solids control. This redundancy is particularly important in high-cost operating environments such as offshore drilling, where any downtime is extremely expensive. Aipu tandem configurations provide integrated multi-shaker solutions with common feed manifolds and coordinated controls.
Typical Configurations by Rig Size
Small workover and water well rigs typically use one mini or small shaker. Medium land rigs commonly operate two to three shakers. Large land rigs and offshore installations may operate four or more shakers configured in parallel or tandem arrangements. Aipu comprehensive product range from 50 to 420 cubic meters per hour and tandem configuration options support all of these rig sizes with properly matched equipment.
