| 20110114309 | SENSOR FOR DETERMINING DOWNHOLE PARAMETERS AND METHODS FOR USING SAME - A system and method for determining a downhole parameter is provided. The system has a sensor positionable on a downhole tool. The sensor comprises insulation positionable on a pad of the downhole tool, and return(s) positionable in the insulation, the return(s) adapted to exchange a current with a power source, the return(s) defining a fluid zone. The sensor comprises a mud button positionable within the fluid zone and in the insulation a distance from the return(s), the mud button exchanging current with the return(s). The mud button and the fluid zone are positioned a distance from the formation such that a majority of the current passing between the return(s) and the mud button passes through the downhole fluid whereby the current exchanged with the mud button generates a measurement of the downhole fluid. | 05-19-2011 |
