Well bottom hole status system

Claim 1

A well bottom hole status indicator system for detecting fluid reservoir pressure and temperature at the bottom of the well bore having tubing extending from the well head to the well bottom hole fluid reservoir and comprising bottom hole instrumentation means removably installed in the well bore in the proximity of the bottom of the well tubing, said bottom hole instrumentation means comprising sensing means for sensing fluid reservoir pressure and temperature, data conversion means operably connected to the sensor means to produce data corresponding to the output of the sensing means, electromagnetic transmitting means operably connected to said data conversion for transmitting data to the well head, said transmitting means comprising a microwave transmitter having a microwave antenna operably connected thereto, said antenna being disposed within the well tubing, power supply means disposed within the bottom hole instrumentation means and operably connected to the sensing means, the data conversion means and the transmitting means; data receiving and processing means disposed at the well head for receiving and processing data from said instrumentation means; and wave guide means interposed between the bottom hole instrumentation means and the data receiving and processing means for guiding the transmitted data to the well head data receiving and processing means, said wave guide means being the tubing itself, the frequency of the microwave transmitter being tuned to an optimum frequency for transmission through the fluid in the tubing and along the inside wall of the tubing, and wherein the data receiver and processing means comprises the microwave receiver having a receiving antenna operably connected thereto, said antenna being disposed inside the tubing at the well head.
