The reactive media interacts with a selected fluid component to control a flow parameter of the conduit. The apparatus also includes at least one sensor responsive to the flow parameter. The apparatus may be used for estimating a water content of a fluid flowing from a subterranean formation. The apparatus may include a flow path configured to convey fluid from the formation. The at least one sensor may be responsive to a pressure change in the flow path caused by interaction of the reactive media with water. ## Claims ### Claim 1 An apparatus for estimating a parameter of interest relating to a fluid, comprising: a conduit; a reactive media in the conduit, the reactive media interacting with a selected fluid component to control a flow parameter of the conduit; and at least one sensor responsive to the flow parameter. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the at least one sensor generates a signal representative of a water content of the fluid in the conduit. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the at least one sensor include a pressure sensor in pressure communication with the fluid in the conduit. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the conduit includes a flexing member; and wherein the at least one sensor includes a strain sensor sensing a response of the flexing member to the flow parameter. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the reactive media includes particles coated with a relative permeability modifier polymer. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the flow parameter is selected from one of: (i) pressure, (ii) flow rate, and (iii) resistance to flow. ### Claim 7 An apparatus for estimating a water content of a fluid flowing from a subterranean formation, comprising: a flow path configured to convey fluid from the formation; a reactive media in the flow path; and at least one sensor responsive to a pressure change in the flow path caused by interaction of the reactive media with water. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein the at least one sensor include a pressure sensor in pressure communication with the fluid in the flow path. ### Claim 9 (depends on 7) The apparatus of claim 7, wherein the conduit includes a flexing member responsive to the pressure change; and wherein the at least one sensor includes a strain sensor sensing a response of the flexing member to the pressure change. ### Claim 10 (depends on 7) The apparatus of claim 7, wherein the reactive media includes particles coated with a relative permeability modifier polymer. ### Claim 11 (depends on 7) The apparatus of claim 7, wherein the reactive media increases flow resistance in the flow path upon interacting with water. ### Claim 12 (depends on 7) The apparatus of claim 7, further comprising an analyzer configured to estimate a water content of the fluid in the container using information generated by the sensor. ### Claim 13 (depends on 7) The apparatus of claim 7, wherein the reactive media is a permeable media having spaces through which the flow fluid flows. ### Claim 14 A method for estimating a parameter of interest relating to a fluid, comprising: estimating at least one flow parameter associated with a fluid flowing along a reactive media in a conduit, the reactive media interacting with a selected fluid component of the fluid; and estimating the parameter of interest using the at least one estimated flow parameter. ### Claim 15 (depends on 14) The method of claim 14, further comprising generating a signal representative of a water content of the fluid in the conduit using at least one sensor. ### Claim 16 (depends on 15) The method of claim 15, wherein the at least one sensor include a pressure sensor in pressure communication with the fluid in the conduit. ### Claim 17 (depends on 15) The method of claim 15, wherein the conduit includes a flexing member; and wherein the at least one sensor includes a strain sensor sensing a response of the flexing member to the flow parameter. ### Claim 18 (depends on 14) The method of claim 14, wherein the reactive media includes particles coated with a relative permeability modifier polymer. ### Claim 19 (depends on 14) The method of claim 14, wherein the flow parameter is selected from one of: (i) pressure, (ii) flow rate, and (iii) resistance to flow. ### Claim 20 (depends on 14) The method of claim 14, further comprising conveying the fluid from a subterranean formation using the conduit.
