Abstract: Determining one or more of a fluid composition, a cement state, or a cement quality of a material located downhole a borehole by using a capacitive sensor or an inductive sensor. The sensors can be located on a pipe positioned downhole or within a swell packer. More than one sensor can be used, for example, as a set of sensor systems. The sensors can be of different sizes, utilize different frequencies, or be spaced unevenly to analyze different shaped areas and depths from the sensors. More than one set of sensors can be employed, such as axially or circumferentially spaced along the pipe or swell packer. The relative dielectric permittivity of the various downhole material can be used to determine when pumped cement has displaced the borehole fluid and when the cement has cured. The process can determine if a micro annulus or crack exists in the cement.
