1. An apparatus for controlling a flow of a fluid between a production string and a formation, comprising:
- a base pipe associated with the production string, the production string having a flow bore aligned with a longitudinal axis of the production string;
a particulate control device wrapped around and contacting an unperforated portion of the base pipe, the fluid flowing substantially axially through the particulate control device in a direction aligned with the flow bore of the production string, the particulate control device reducing an amount and size of particles in the fluid; and
a flow control device axially adjacent to the particulate control device, the flow control device including a retrievable flow restriction element in fluid communication with the particulate control device, the retrievable flow restriction element being positioned in a pocket radially offset from the flow bore and configured to control a flow parameter of the fluid flowing between the particulate control device and the flow bore of the production string, wherein the flow restriction element is configured to be retrieved through the flow bore of the production string.

Abstract
An apparatus and associated method for controlling a flow of a fluid between a wellbore tubular and a formation may utilize a particulate control device positioned external to the wellbore tubular and a flow control device having a retrievable flow restriction element that controls a flow parameter of a fluid flowing between the particulate control device and a bore of the wellbore tubular. The flow control device may be re-configured in the wellbore and/or be used to inject a fluid into the formation.

7. A method of controlling a flow of a fluid between a production string and a formation, comprising:
-
positioning the production string in a wellbore intersecting the formation, the production string having a flow bore aligned with a longitudinal axis of the production string, the production string further comprising a flow control device and a particulate control device, the flow control device being axially adjacent to the particulate control device, the particulate control device wrapped around and contacting an unperforated portion of a base pipe of the production string; positioning a flow restriction element in the flow control device in a pocket radially offset from the flow bore of the production string, wherein the flow restriction element is retrievable through the flow bore of the production string; adjusting a flow characteristic of the flow control device positioned in the wellbore using a running tool conveyed into the wellbore; conveying a fluid into the wellbore via the production string; and injecting the fluid into the particulate control device using the flow restriction element, the fluid entering the particulate control device in an axial direction. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. A method for controlling a flow of a fluid between a production string and a formation, the production string having a flow bore aligned with a longitudinal axis of the production string, the method comprising:
-
injecting a first fluid into the formation using a flow control device positioned in the wellbore, the flow control device having a flow restriction element positioned in a pocket radially offset from the flow bore of the production string and axially adjacent to a particulate control device wrapped around and contacting an unperforated portion of a base pipe of the production string, the first fluid entering the particulate control device in a direction aligned with the flow bore; adjusting at least one flow characteristic of the flow control device positioned in the wellbore using a setting device conveyed into the well; and injecting a second fluid into the formation using the flow control device. - View Dependent Claims (17, 18, 19, 20)
