Floway Tesla Autonomous ICD
A Novel Passive Autonomous Inflow Control Device 
(We are actively looking for local agents in key markets like ME, LA, Africa, Australia etc., please contact us if you are interested!)

Floway is proud to introduce a new generation Inflow Control Device (ICD) – the Tesla AICD.  

As shown in the figures below, horizontal wells are often subject to uneven production profiles.

Figure 1 - Homogenous reservoir's uneven production due to friction pressure loss in the tubing

Figure 2 - Heterogenous reservoir's uneven production due to permeability differences

To combat these problems, passive Inflow Control Devices (ICD) were created and have been used successfully around the world at improving recovery and delaying the onset of water or gas breakthrough.


Passive ICD’s are limited in that production rates for the unwanted fluid tend to be higher than that for oil.  This is true regardless of passive ICD type, especially as oil viscosity (cP) increases.


The Tesla AICD is a significant improvement over ICD designs. In addition to providing the typical passive ICD benefits, Floway’s patented design delivers the functionality to decrease flow rate for water production.   Floway’s innovative Tesla AICD is similar to,  most other Autonomous Inflow Control Devices, and in the mean time is reliable and cost effective (one piece carbide with no moving part)  for a range of oil viscosities.

The working principles are:

·  Flow restriction is based on fluid impingement

·  Lower cP fluid changes direction based on inertia

·  Higher cP fluid uses centrifugal force to change directions

·  Changing direction creates more impingement for water than oil due to inertia

·  Impingement creates the pressure drop which reduces flow

Figure 4- Flow rate comparison between Tesla AICD and nozzle ICD. As shown in the Figure, the curves are scaled to produce same amount of water for easy comparison of oil rates at various viscosities. While producing the same amount of water, Tesla AICD can produce significantly more oil than nozzle at the same condition (viscosity and pressure) . 

Tesla AICD features:

·  No moving parts

·  Up to six (6) devices per joint

·  Larger flow path than conventional designs

·  Produce and inject through the same device without modification



Benefits include:

·  Life of the well reliability

·  Reduced plugging risk

·  Higher oil flow potential than passive ICDs

·  Higher ultimate recovery

·  Less water handling at surface 

With designs guided by advanced fluid dynamics theory the tool dramatically reduces fluid velocity before entering production tubing.  Thus, unlike conventional nozzle-type ICDs, there is virtually zero erosion risk from jetting on the tubing.
