Balance flow across the entire completion interval
ResFlow inflow control devices (ICDs) and ResInject injection ICDs help maintain uniform inflow and injection rates, respectively, across the entire length of the interval in openhole completions, even in the presence of permeability variations and thief zones.
Combined with the strength and accuracy of Schlumberger screens, they give you an intelligently integrated flow management system that regulates itself without the need for downhole telemetry.
Produced fluid enters the production tubing through the ICD. In high-permeability or high-pressure zones, the higher fluid velocity causes the ResFlow ICD to exert higher backpressure than in less productive zones. Consequently low-productivity zones are stimulated to produce more than in conventional screen completions, minimizing the risk of bypassing reserves and increasing hydrocarbon recovery.
Moreover, the ICD dramatically reduces water and gas rates when these breakthrough phases have higher mobility than the oil.
ResFlow ICDs and ResInject injection ICDs help maintain uniform inflow and injection rates, respectively, in openhole completions. Both ICDs are made of a LineSlot premium direct-wire-wrapped screen wrapped on unperforated basepipe with a housing located at the upper end of the screen.
For the ResFlow ICD, fluids enter the screen, flow between the screen jacket and basepipe into the housing, and then flow through the nozzles into the production screen.
For the ResInject injection ICD, fluids enter the housing, flow through the nozzles into the screen section between the screen jacket and basepipe, and then flow into the reservoir.
