  • Patent number: 11169032
    Abstract: Memory gauge and method for processing recorded raw data acquired with a memory gauge in a well. The method includes selecting a first calibration table (C1), of the memory gauge, that has a highest calibration value for the measured parameter; performing a first analysis of the recorded raw data using the first calibration table (C1) to determine a highest measured value of the measured parameter; comparing the highest measured value of the measured parameter with highest calibration values of the plural calibration tables of the memory gauge; and when a highest calibration value of a second calibration table is closer to the highest measured value of the measured parameter than the highest calibration value of the first calibration table, selecting the second calibration table (C2); and performing a second analysis of the recorded raw data using the second calibration table (C2) to generate measured values of the measured parameter.

  • Patent number: 9670772
    Abstract: The present invention concerns a method and a well string element for transmitting data in a well. The well string element (20c) includes an elongated body (80) that defines a through channel (110) and also includes a side pocket (92) that is open to ambient (91); and an acoustic modem (60) provided in the pocket (92) and configured to emit acoustic waves. The acoustic modem (60) is configured to receive electrical signals from one or more sensors (50, 52), transform the electrical signals into the acoustic waves and emit the acoustic waves into a wall (112) of the elongated body (80) when receiving an acoustic wake-up call from a device (70) outside the drill string element (20c).
