Apparatus and method for providing communication between a probe and a sensor

A method for communicating a sensor located within a tubing string with a probe concentrically disposed within the tubing string, said tubing string containing a drilling fluid, wherein said tubing string containing an internal diameter portion and said probe having an outer periphery, the method comprising:

• providing the sensor within the tubing string, the tubular string being a conductive material;
• generating a reading from the sensor;
• transmitting the reading to a first modem means;
• modulating the reading onto a carrier wave to produce a modulated signal;
• directing the modulated signal to a tubing string antenna coil winding, said tubing string coil winding disposed about the inner diameter portion located within the tubing string;
• generating an electromagnetic signal with the tubing string antenna coil winding in response to the reading from said sensor;
• receiving the electromagnetic signal with a probe antenna coil winding that is disposed about the outer periphery of said probe;
• demodulating the electromagnetic signal within a second modem means in the probe to the reading;
• transmitting the reading to a probe electronics module located within the probe.

A wireless system for communicating a sensor with a probe in a well bore, said well bore having a drilling fluid disposed therein comprising:

• a conductive metal housing concentrically positioned within said well bore, said housing containing the sensor and having an internal diameter portion therein, and wherein the probe is slidably disposed within said internal diameter portion;
• a first processor means, disposed within said housing, for receiving a reading generated by the sensor and generating an output reading;
• a first modem means, electrically connected with said first processor means, for modulating the output reading;
• a housing antenna coil, electrically connected with said first modem means, for generating a modulated electromagnetic wave, said housing antenna coil disposed about said internal diameter portion;
• a probe antenna coil, disposed about an outer periphery of said probe, for receiving the modulated electromagnetic wave so that a gap is formed between said sensor antenna coil winding and said probe antenna coil winding forming a passage for the drilling fluid and for the transmission of the modulated electromagnetic wave;
• a second modem means, electrically connected with said probe antenna, for demodulating said modulated electromagnetic wave to the output reading;
• a second processor means, electrically connected with said second modem means and positioned within said probe, for processing and recording the output reading into a digital record;
• and wherein an operating frequency range of said housing antenna coil and said probe antenna coil is between 10,000 Hertz and 100,000 Hertz.
