The DAR Technology
First Universal Inflow Control Solution (UICS)
Density Activated Recovery (DAR) by Innowell Solutions is a new generation inflow control technology based on simple and robust mechanical principles, that resolves the challenges associated with current inflow control technologies and provides truly game-changing capabilities:
The DAR technology therefore represents a new generation inflow control technology: the Universal Inflow Control Solution (UICS).
In many high-productivity fields, oil recovery has been radically improved through downhole inflow control, initially through passive fixed-geometry Inflow Control Devices (ICDs) and later through Autonomous ICDs (AICDs), which discriminate between wanted and unwanted fluids. There are however limitations with existing technologies:
If the limitations of existing technologies were addressed, higher deployment rate of downhole inflow control could be achieved, especially for maximum reservoir contact wells, which typically penetrate several formation layers with large variations in reservoir properties.
The goal for the development of the DAR Technology was to enable inflow control without limitations. This way, inflow control as a very successful IOR technology could become available to substantially more fields and wells, regardless of fluids and reservoir conditions.
Innowell’s DAR Technology imposes negligible pressure drop and works independently of fluid viscosities, pressure conditions, local inflow rates and reservoir properties. Negative consequences of geological uncertainty are thereby eliminated, and sustained high oil production can be combined with an insurance against loss of revenues caused by early breakthrough of water and/or gas.
