    摘要: A thermoelectric generator for producing electric power from heat in fluids produced from a subsurface wellbore includes a conduit for moving therethrough fluids produced from the Earth's subsurface and at least one thermoelectric module affixed to an exterior of the conduit. The at least one thermoelectric module includes a collimating heat transfer device in contact with the conduit on a first side and in contact with a first side of a thermoelectric generator thermocouple on a second side. A second side of the thermocouple is in contact with a contact surface of a heat sink. The heat sink is exposed to ambient atmosphere at the Earth's surface to conduct heat away from the thermocouple.

    摘要: A wireless casing collar locator includes a pipe coupling detector configured to be conveyed through a wellbore. A detection device is associated with the pipe coupling detector. The detection device generates an output indicative of detection of a pipe coupling in response to the output of the pipe coupling detector. The locator includes an acoustic transmitter functionally associated with the detection device. The transmitter is configured to apply an acoustic impulse to a conveyance device used to move the locator along the wellbore in response to communication to the transmitter of the output of the detection device. A surface receiver and processing unit used to convert acoustic energy into electrical energy for processing in real time to determine the location of the pipe detector in wellbores.
