Watercut sensor using reactive media

摘要

An apparatus for estimating a parameter of interest includes a conduit and a reactive media in the conduit. 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.

1. A method for estimating a parameter of interest relating to a fluid, comprising:
positioning a flexing member along a conduit; positioning a reactive media in the conduit, the reactive media interacting with a selected fluid component to control a flow parameter of the conduit; and estimating the flow parameter using at least one sensor, the flow parameter being affected by interaction of the reactive media with the selected fluid component, wherein the at least one sensor includes a strain sensor sensing a response of the flexing member to the flow parameter.
