Sand control system adapted for water injector wells
Downhole engineering specialist Tendeka has introduced the Cascade3 sand control technique.
This is said to eliminate failure mechanisms associated with water injection wells, leading to improved injectivity, recovery, and well life.
Water injection wells, with sustained high rate and high ultimate volumes, are critical to many subsea and deepwater developments, Tendeka points out, and can boost oil recovery by 20%, due to a more effective sweep of the reservoir.
However, they also present challenges such as crossflow, backflow, and water hammer which lead to fines building up inside the sand screen completion and impaired injectivity.
Cascade3 is designed to be compatible with gravel packs and stand-alone screens, and prevents any backflow while allowing unrestricted injection.
The system is said to boost production and lessen the need for interventions and re-drills, thereby lowering long-term operational costs.
COO Gary Smart said: “Cascade3 was developed with a major Gulf of Mexico operator to increase the longevity of their subsea water injection wells. By doing this, less wells are required to be drilled to maintain production...”
