Sand control technology to boost well life

Cascade3 is a valve-and-screen solution. High density of flow control valves are mounted within conventional sand screens to allow high water injection rates while increasing sand control reliability and maintaining injectivity over time.

According to Tendeka, the product eliminates the failure mechanisms associated with water injection wells, providing operators with improved injectivity, recovery, and well life.

While water injection programmes can optimise oil recovery by 20 per cent, crossflow, backflow and water hammer can lead to fines building up inside the sand screen completion and impaired injectivity.

Cascade3 is compatible with gravel packs and stand-alone screens, and prevents backflow while allowing unrestricted injection. In addition to boosting production, CascadeĀ³ reduces the need for interventions and re-drills, lowering long-term operational costs.
