Abstract
In a method and apparatus for estimating a downhole fluid parameter include a body having an elongated cavity defined by an electrically conductive inner surface, an central electrical conductor located coaxially within the cavity, wherein an annular region is defined by the cavity inner surface and an outer surface of the electrical conductor. A fluid is conveyed to the annular region. A first electrode is coupled to the central electrode, a second electrode coupled to the central electrode, and at least one intermediate electrode coupled to the central electrode between the first electrode and the second electrode. An input signal is applied to the central electrode and first and second output signals are emitted from the second electrode intermediate electrode. The output signals are used in part to estimate the fluid property of the fluid existing in the annular region.
