Inflow and Injection Control Devices

Balance flow across 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.

North Caspian Extended-Reach Wells Completed Without Washpipe, Saving 2 days and USD 2 Million per Well

An operator developing an oil field with openhole extended-reach wells used ResFlow CV ICD to allow cleanup and displacement of oil-base mud without the use of washpipe. Read case study


Improve hydrocarbon recovery

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.

During injection, fluid flows through the ResInject injection ICD before entering the reservoir. Low-permeability zones receive more fluid than they would in conventional completions because the lower fluid velocity results in lower backpressure, again improving sweep and hydrocarbon recovery.

ResFlow CV ICD eliminates need to run washpipe

The ResFlow CV check-valve ICD is an inflow control device that eliminates the need to deploy washpipe for well cleanup (fluid displacement) and for setting openhole hydraulically set packers. The check-valve assembly, which includes a ceramic nozzle, a ceramic or aluminum ball, and an aluminum plate, is used instead of the standard ResFlow ICD nozzle assembly within the ICD housing. The check-valve assembly prevents fluid loss through the nozzles during washdown and then controls the flow of hydrocarbons during production, in the same way as a conventional ResFlow ICD.
