Autonomous Inflow Control Devices - Type 2N

ResFlow™ AICD 2N is a cyclonic-flow-based autonomous inflow control device (AICD) that improves well performance by autonomously managing inflow to restrict gas and water while maintaining optimal oil production rates. Moreover, by applying higher backpressure in high-permeability or high-pressure zones, these devices promote uniform drawdown across the reservoir and minimize bypassed reserves, further increasing total recovery. This dynamic response reduces the volume of unwanted fluids handled at surface, lowers operational costs, and extends well life with fewer interventions.

Produced fluids enter the ResFlow AICD 2N through the screen assembly. Within the device, the flow path induces rotational motion that differentiates fluid phases. Oil exits with minimal pressure drop, similar to passive ICDs. In contrast, lower-viscosity gas and water experience higher rotational velocities that generate greater pressure drops, restricting production of these fluids. The higher the proportion of gas or water, the greater the restriction. This autonomous mechanism operates without external control or moving parts. The ResFlow AICD 2N device boosted production by 41% and cut emissions in Peru by reducing water production.
