A method for monitoring a fracturing operation in a target well comprising extending a seismic sensor in a tubing string to a first position in an well offset from the target well. A coolant fluid is circulated through the tubing string for a predetermined time. The tubing string is retracted to a second uphole position such that the cooled seismic sensor is exposed in the offset wellbore. A seismic signal emitted during the fracturing operation of the target well is sensed in the offset well.

Methods for cooling measuring devices in high temperature wells

A seismic acquisition system comprising a remote-controlled buoy for conducting seismic acquisition operations. The buoy comprises an operating system for operating a seismic wave production device on the buoy, a placement system, a communications system, and dynamic position locating system. The seismic acquisition system also comprises a remote control system for controlling the buoy systems. The seismic acquisition system also comprises receivers for receiving the seismic wave and generating a data signal indicative of the received seismic wave. The seismic acquisition system operates by controlling the placement system with the remote control system to position the buoy and then controlling the operating system with the remote control system to produce a seismic wave from the seismic wave production device. The receivers then receive the seismic wave and generate a data signal indicative of the seismic wave. The time of producing the seismic wave as well as the position of the buoy at the time of production are then analyzed with the data signal by a data processor.
