Abstract
The water cut of a fluid used or produced in conjunction with wellbore operations may be measured or otherwise estimated using an ion selective fiber sensor. For example, a method may include flowing a fluid comprising an aqueous phase and an oleaginous phase through a sensor; contacting an ion selective fiber positioned in the sensor with the fluid, wherein the ion selective fiber has an intrinsic time constant (τ) associated with an intrinsic color change of the ion selective fiber in response to contact with the aqueous phase; measuring a color change of the ion selective fiber in response to contact with the fluid as a function of time; deriving an effective time constant (τ) for the color change of the ion selective fiber in response to contact with the fluid; and calculating a water cut (Y) in the fluid based on
