ResFlow check-valve ICD

ResFlow check-valve ICDs enhance production by balancing in ow along the entire wellbore, promoting uniform reservoir depletion and maximizing recovery. In addition, they eliminate the need for washpipe during completion installation, simplifying operations and reducing opex—particularly valuable in offshore and extended-reach applications. Absence of washpipe also enables deploying longer bottomhole assemblies for increased reservoir access.

The check-valve design prevents fluid loss during completion installation, maintaining hydraulic integrity. Once production starts, the ICDs help minimize early water or gas breakthrough by ensuring even drawdown across varying reservoir permeabilities, contributing to extended well life and improved sweep efficiency.

Thus, integrating fluid-loss control directly into the ICD simplifies openhole completion designs while delivering more efficient well cleanup, improved production management, and long-term reservoir performance.

• Carbonate and sandstone reservoirs
• Extended-reach completions
• Horizontal and highly deviated wells
• Multizone openhole completions with hydraulic-set packers
• Stand-alone screen completions
