Abstract
The present invention relates to a downhole inflow control system for controlling an inflow of fluid into a casing from outside the casing, such as from a reservoir or an intermediate casing. The downhole inflow control system comprises a casing having an axial extension and a wall having a wall thickness (t), an inflow control valve having a housing, an axial extension in an axial direction along the housing, and a spring element moving in relation to the housing, thereby controlling the inflow of fluid through the valve from an inlet of the housing to an outlet of the housing.
