Abstract
A method detects at least one phase of multiphase borehole fluids within a borehole. The method has a step of providing coiled tubing connected to a top end of a bottom hole assembly having a sensor configured to detect a property associated with the multiphase borehole fluids. Further, the method has a step of positioning the sensor adjacent to a first phase of the multiphase borehole fluids by rotating the bottom hole assembly or a portion of the bottom hole assembly. Moreover, the method has the steps of detecting a first measurement with the sensor as the sensor rotates and determining a fractional amount of at least one phase of the multiphase borehole fluids.
