ABSTRACT:
The amplitude variation of an acoustic wave propagated within drilling mud mixed with a mineral-deposit fluid is measured and compared with the amplitude of a reference wave obtained from the drilling mud alone. The method and the device are primarily applied to the detection of an inflow of oil or gas during a well-drilling operation.
