La diagraphie sonique a maintenant de multiples applications pour: In the common-shot gather, the refracted arrivals and borehole modes have linear moveout across the offset range, while the reflected events have hyperbolic moveout.

Geophysics Oil and Natural Gas Extraction. Usually measured in microseconds per foot.

A method that measures the time required for sound impulses to travel through a given length of rock. After filtering, the residual sonic section shows the refracted modes and the leaky modes Fig. The vertical well was drilled to establish a vertical soniqje cross-section of the quarry and to identify the acoustic impedance variation boundaries.

We describe different processing sequences applied to a set of field examples.

Translation of “diagraphie sonique” in English

First used for seismic-velocity information, it is now used chiefly for estimating porosity and lithology by the empirical Wyllie time-average equation. The signal to noise ratio is enhanced by spectral matrix filtering. Each filter is designed to cancel a selected wave, characterized by its velocity. A record of the measurement of porosity done by comparing depth to the time it takes for a sonic impulse to travel through a given length of formation.

The sonic tool used was a Schlumberger Dipole Imaging tool. The borehole Stoneley waves are trapped modes that can be reflected when the direct borehole Stoneley wave encounters permeable fractures Hornby, Johnson, Winkler and Plumb, or a major change in diagralhie Hornby, This sonic section mainly contains upgoing reflected Stoneley waves.

First used for seismic-velocity information, it is now used chiefly for estimating porosity and lithology by the soniique Wyllie time-average equation. Figs 10 to 13 show the sonic fullwaveform sections after constant offset gather processing. Volume 47, Number 2March-April In sandstones, the interface modes have strong amplitudes and a low frequency content.

After filtering, the residual sonic section contains the noise and the other waves.

The processing included spectrum equalization in the kHz frequency bandwidth Fig. For this experiment, the monopole transmitter was activated with a low frequency pulse for the purpose of generating low frequency Stoneley waves.

It was used to enhance the interface modes Fig. IFP Energies nouvelles, Vol.

The full waveforms taken at each receiver were recorded on magnetic tape. The value of the Stoneley frequency is directly related to shaliness.
