  • BOREHOLE TEMPERATURE MONITORING
    Publication number: 20250052553
    Abstract: The disclosure provides a detonator which includes an oscillator, and a memory unit in which is stored a first measurement which is based on the frequency of oscillation of the oscillator at a first temperature and a second measurement which is based on the frequency of oscillation of the oscillator at a second temperature. The disclosure further extends to a method of monitoring a temperature in a borehole which includes the steps of using the first and second frequency measurements and the first and second temperatures to establish a frequency versus temperature relationship for the oscillator, placing the oscillator into the borehole, obtaining a third measurement of the frequency of oscillation of the oscillator while it is in the borehole, and using said frequency versus temperature relationship and the third frequency measurement to determine the temperature of the oscillator at the time the third frequency measurement was obtained.
