1. An apparatus for controlling a flow of a fluid between a wellbore tubular and a formation, comprising: a flow control device having a first opening, a second opening, and flow space forming a fluid path between the formation and the wellbore tubular formed therein, the fluid path being between the first opening and the second opening; anda flow control element positioned in the flow space, the flow control element being configured to flex radially outward from a first radial position to a second radial position in response to a change in a pressure differential along the flow space, wherein the fluid flows across the flow space when the flow control element is in the first radial position and the second radial position and wherein an increase in the pressure differential reduces a gap along the flow space, wherein the flow control element is configured to reduce a space between an inner surface of the flow control device and the flow control element as fluid flow increases in the space, and wherein the space remains after the flow control element flexes to a radially outward position, and wherein the flow control element expands radially outward in response to an increase in a pressure applied on a surface facing the flowing fluid. 2. The apparatus according to claim 1 wherein the flow space is defined at least partially by an inner surface of the flow control device, and wherein a radial flexure of the flow control element varies a space between the inner surface and the flow control element, and wherein the flow control element is configured to revert to a radially smaller shape, wherein the flow control element is configured to seat on the wellbore tubular. 3. The apparatus according to claim 1 wherein the flow control element includes a sleeve element and a movable portion projecting radially outward from the sleeve element. 4. The apparatus according to claim 3 further comprising a plurality of movable portions projecting radially outward from the sleeve element. 5. The apparatus according to claim 1, wherein the flow control element is formed at least partially of one of: (i) elastomer, (ii) polymer, and (iii) a metal. 6. The apparatus according to claim 1, further comprising a biasing element applying a biasing force to the flow control element. 7. The apparatus according to claim 6, wherein the biasing element urges the flow control element to a radially retracted shape. 8. A method for controlling a flow of a fluid between a wellbore tubular and a formation using a flow control device, the flow control device including a first opening, an second opening, and a flow space between the first and the second opening, comprising: controlling fluid flow between the formation and the wellbore tubular in a flow control device along the wellbore tubular by using a flow control element configured to flex radially outward from a first radial position to a second radial position in response to a change in a pressure differential in flow space, wherein the fluid flows along the wellbore tubular when the flow control element is in the first radial position and the second radial position, and wherein an increase in the pressure differential reduces a gap along the flow space, wherein the flow control element diametrically expands when flexing from the first radial position to the second radial position, and wherein the flow control element expands radially outward in response to an increase in a pressure applied on a surface facing the flowing fluid. 9. The method according to claim 8 further comprising seating the flow control element on the wellbore tubular, and varying a size of a flow space in the flow control device using the flow control element. 10. The method according to claim 8 wherein the flow control device includes an annular flow space; and wherein the flow control element is an annular member. 11. The method according to claim 8 wherein the flow control element is formed of an elastically deformable material. 12. The method according to claim 8 further comprising biasing the flow control element to the first radial position. 13. The method according to claim 8, wherein the flow control element is formed at least partially of one of: (i) elastomer, (ii) polymer, and (iii) a metal. 14. A system for controlling a flow of a fluid a wellbore tubular, comprising: a plurality of flow control devices positioned along the wellbore tubular, wherein each flow control device has a flow space formed therein that allows fluid flow from a first opening in communication with the formation into a second opening in communication with the wellbore tubular; anda flow control element positioned in each flow space, each flow control element having a surface facing a first opening receiving the fluid from the formation, each flow control element being configured to flex radially outward from a first radial position to a second radial position in response to an increase in a pressure applied on the surface facing the fluid flowing from the first opening, wherein the fluid flows across the flow space when the flow control element is in the first radial position and the second radial position, and wherein an increase in the pressure differential reduces a gap along the flow space. 15. The system according to claim 14 wherein each flow control element is configured to provide a predetermined drainage pattern from the formation. 16. The system according to claim 15 the predetermined drainage pattern is a substantially even drainage of fluid from at least a portion of the formation. 17. The system according to claim 14 wherein each flow control element is configured to provide a predetermined fluid injection pattern for the wellbore tubular. 18. The system according to claim 14 wherein the fluid injection pattern is a substantially even injection of fluid into at least a portion of the formation.
