Following two years of research and development, Tendeka has introduced its Cascade3, which is designed to eliminate the failure mechanisms associated with water injection wells. The technology is set to provide operators with improved injectivity, recovery and well life.
In conventional reservoirs, a significant portion of oil production is driven by water injection into unconsolidated reservoirs. Water injection wells, with sustained high rate and high ultimate volumes, are critical for the economic success of many subsea and deep water developments around the world: the Gulf of Mexico, West Africa, North Sea and South East Asia, to name a few.
Water injection programmes 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 compatible with both gravel packs and stand-alone screens, and prevents any backflow whilst allowing unrestricted injection. In addition to boosting production, the technology reduces the need for interventions and re-drills, significantly lowering long-term operational costs.
Gary Smart, CEO of Tendeka, 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, delivering real value to our client.”
