Workover rigs have specific requirements for shale shaker equipment that differ from new-drill applications. Aipu Solids Control provides shale shaker solutions configured for workover operations with appropriate capacity, compact dimensions, and specialized features.


Capacity-Matched for Workover Flow Rates
Workover operations typically involve lower circulation rates than new drilling. Aipu Hunter-Mini and Hunter-MG3 models provide capacity appropriately matched to workover requirements without the unnecessary size and cost of full drilling shakers. These compact units process workover fluid volumes efficiently while occupying minimal rig space. The Hunter-Mini at 50 cubic meters per hour is particularly well-suited for smaller workover units and coiled tubing operations.
Handling Workover Solids Characteristics
Workover operations encounter different solids types than new drilling: metal debris from milling operations, degraded proppant from frac sand flowback, corrosion products and scale from production tubing, and formation fines from near-wellbore damage removal. Aipu shakers handle these diverse solids types through adjustable operating parameters and appropriate screen selection. Quick-change screens allow rapid mesh changes as solids characteristics change during the workover program.
Compact Design for Workover Rig Integration
Workover rigs have more constrained space than drilling rigs. Aipu compact models are designed for integration into workover fluid systems without extensive modification. Low-profile designs fit under limited headroom. Standardized connections simplify rig-up and rig-down during frequent workover moves. The self-contained design minimizes auxiliary equipment requirements.
Fluid Recovery for Cost-Sensitive Operations
Workover economics are typically tighter than new drilling budgets. Aipu shakers maximize fluid recovery through effective solids separation, reducing the volume of expensive completion and workover fluids lost with discarded solids. The drier cuttings discharge from Aipu high-G shakers further reduces fluid losses, directly improving workover economics.
