摘要： A communications path between a surface control system (142) and downhole equipment includes a network of wirelessly interconnected communication devices (114) that are located along a conduit (108). When the communications path fails or cannot be established during performance of a downhole operation, a mobile master communication tool (150) that is in communication with the surface system (142) can be deployed within the wireless range of one of the devices (114) to provide an alternative communication path between the surface system and the downhole equipment.

摘要： A modem is described having an acoustic transceiver assembly, transceiver electronics including transmitter and receiver electronics coupled to the transceiver assembly, at least one processing unit coupled to the transceiver electronics, a non-transitory processor readable medium coupled to the at least one processing unit, and a power supply supplying power to the transceiver assembly and the transceiver electronics. The non-transitory processor readable medium stores unique identifiers, a set of communications parameters, and processor executable instructions which enables the receiver electronics to receive a first communications message; enables the transmitter electronics to transmit a test message with the set of communications parameters to a predetermined modem; enables the receiver electronics to receive an acknowledgement message with the set of communications parameters from the predetermined modem; and enables the transmitter electronics to transmit a second communications.

摘要： A system disclosed herein is for determining position of a distal end of a tubular string in a wellbore formed in a subsurface formation. The system includes casing lining the wellbore, with the casing carrying a plurality of radioactive sources. A tubular string is disposed in the wellbore and carries a radiation sensor along a length thereof. A processor is associated with the radiation sensor, and is configured to measure intensity of radiation received from the plurality of radioactive sources, and determine the position of the distal end of the tubular string by correlating a formation or wellbore fluid property that varies as a function of position within the wellbore and the measured intensity of the radiation received from the plurality of radioactive sources.
