Abstract (en)
An apparatus is made of a surface communication system for communicating wirelessly with a first wireless modem mounted within a section of tubing, and configured to communicate wirelessly with a second wireless modem through a tubing including the section of tubing and within a well at a distance in excess of 500 feet , comprising: a transceiver assembly adapted to be positioned on the section of tubing and in close proximity with the first wireless modem; transmitter electronics configured to provide low power signals to the transceiver assembly to cause the transceiver assembly to generate low power wireless signals into the section of tubing to be received and interpreted by the first wireless modem; and receiver electronics configured to receive and interpret high power signals from the transceiver assembly.
