A technique facilitates the inflow of desired fluids into a downhole well completion while restricting the inflow of undesirable fluids. The technique utilizes at least one autonomous inflow control device which is placed along a well completion to control inflow of fluid from an exterior to an interior of the well completion. The autonomous inflow control device utilizes a plurality of shiftable elements which automatically shift in their relative positions based on the density of fluid in the autonomous inflow control device. This automatic shifting causes the alignment or misalignment of flow openings so as to allow free flow of a desired fluid through the autonomous inflow control device and into the interior of the completion while automatically restricting flow of an undesirable fluid.

Autonomous inflow control device system and method

A screen assembly includes a base pipe, plurality of joints including a filter layer disposed around the base pipe, a drainage layer between the filter layer and the base pipe, and a drainage layer connector positioned between adjacent joints. The base pipe include base pipe connectors aligned with the drainage layer connectors. A flow path exists from an outer annulus between an open hole and the filter layer of the joints, into the filter layer and the drainage layer, across the drainage layer in a downhole direction, across an annulus between the drainage layer connector and the base pipe, into a portion of the drainage layer corresponding to a bottom-most joint, and into an interior of the base pipe via an open flow area at the bottom-most joint for returning to surface.

Gravel packing with base pipe having limited open flow area

A tool includes a mandrel and at least one gate. The mandrel includes a bore, and the mandrel is able to connect in-line with at least one sand control device of a bottom hole assembly such that the mandrel is coaxial with the at least one sand control device. The mandrel also includes a flow path configuration, such as, at least one flow path connecting the at least one sand control device to the bore, at least one flow path connecting the bore to at least two sand control devices, and at least one flow path connecting the bore to the at least one sand control device and to another device of the bottom hole assembly. The at least one gate has an initial position, and the at least one gate is configured to move from the initial position into a different position to control fluid flow.

A technique facilitates the production of well fluid. According to an embodiment, an inflow assembly may be deployed downhole with, for example, completion equipment used in the production of well fluid. The inflow assembly comprises a first inflow control device and a second inflow control device disposed in series along a flow path routed between an exterior and an interior of the inflow assembly. As well fluid flows into an interior of the inflow assembly along the flow path, the first inflow control device and the second inflow control device perform different tasks with respect to controlling fluid flow. The different tasks may be selected to, for example, facilitate production of well fluid while protecting the completion equipment.

Inflow control system

A technique facilitates improved control over inflowing fluids with respect to, for example, a screen assembly or screen assemblies of a tubing string deployed in a wellbore. The improved control may be provided by at least one inflow control device comprising a housing defining a chamber having a first end and a second end through which fluid may flow. Additionally, the inflow control device comprises at least one inlet passage disposed at the first end and having a contour which provides a desired effect on the inflowing fluid according to the type of fluid, e.g. according to the viscosity of the fluid. The contour may comprise an expanding cross-sectional area, e.g. a cone or other expanding shape. In some embodiments, the entrance of the inlet passage may have a rounded edge to, for example, create an initially decreasing and then increasing cross-sectional area along the inlet passage.
