Abstract: 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.

Abstract: An apparatus includes an inflow control device that is disposed in a well and is adapted to receive a flow. The inflow control device includes a chamber, an outlet and at least one inlet. The chamber has a first end, a second end, and a cross-section of the chamber decreases along a length of the chamber. The outlet is disposed at the second end of chamber. The inlet has a cross-sectional dimension and is adapted to, in response to the received flow, inject a flow into the chamber near the first end of the chamber such that a fluid flow is produced inside the chamber that rotates and translates in a direction along the length of the chamber toward the outlet.

Abstract: Systems and methods for monitoring a position of a service tool in a wellbore are provided. The service tool can have a sensor assembly coupled thereto and be positioned within the wellbore. The service tool can be moved within the wellbore. The distance travelled by the service tool in the wellbore can be measured with the sensor assembly. The position of the service tool in the wellbore can be determined by comparing the distance travelled to a stationary reference point.

Abstract: An apparatus that is usable with a well includes a housing and a body. The housing includes an inlet and an outlet, and a fluid flow is communicated between the inlet and outlet. The body disposed inside the housing to form a fluid restriction for the fluid flow. The body includes an opening therethrough to divert a first portion of the fluid flow into a first fluid flow path; and a first surface to at least partially define the first fluid flow path. The body is adapted to move to control fluid communication through the first flow path based at least in part on at least one fluid property of the flow

Abstract: 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.

Abstract: A technique facilitates regulation of flow through a flow control device to improve a well operation, such as a production operation. The technique utilizes a flow control device which has a valve positioned in a housing for movement between flow positions. The different flow positions allow different levels of flow through a primary flow port. At least one flow regulation element, e.g. a Venturi based flow regulation element, is used in a control line in communication with the valve to establish a differential pressure acting on the valve. The differential pressure is a function of fluid properties and is used to autonomously actuate the flow control device to an improved flow position.
