On this section we can observe good correlation between the frequency log and lithology derived from an independent analysis.

Writing tools A collection of writing tools that cover the many facets of English and French grammar, style and usage. Usually measured in microseconds per diagrahpie.

Enregistrement de la vitesse du son.

The record resulting from this process is called “acoustic log. The filter was applied in the 0 to 2. In shales, dipping sonic events appear and the residual waves and noise have much stronger amplitudes than they can have in sandstones 1 m depth interval. A collection of writing tools diagrapnie cover the many facets of English and French grammar, style and usage.

Geophysics Oil and Natural Gas Extraction. The great amount of full-waveform sonic data leads geophysicists and log analysts to implement algorithms for separating waves. The sonic tool used was a Schlumberger Dipole Imaging tool. The acoustic data must be recorded with well suited spatial and temporal sampling-rates to avoid spatial and temporal aliasings.

Note that the diffractions, at the acoustic log scale, appear as variations in the shape of the reflected event associated with the dolomitic zone, at the VSP-CDP stack scale Fig.

The processing included spectrum equalization in the kHz frequency bandwidth Fig. Each filter is designed to cancel a selected wave, characterized by its velocity.

The use of information coming from vertical well VSP and log and synthetic modeling leads us to differentiate the reflections coming from discontinuities situated above A and below B the horizontal well. The receiver section contains eight dipole-monopole stations spanning 3.

The source was fired at equal spacings of 5 cm throughout the open hole section of the well. The sonic data were recorded to study the reflected Stoneley waves. The residual constant-offset section was corrected for normal moveout digraphie the velocity function derived from the acoustic log.

Each filter was applied in a time-window in order to select a specific wave.

Enregistrement de la vitesse du son. For each gather Fig. After filtering, the standard deviation is reduced whatever the diagraphiee, but mainly in the depth interval. Volume 47, Number 2March-April At about 1 m, diffractions can be observed on the filtered sonic section Fig.

The source was fired at equal spacings of 6 inches throughout the open hole section. For this experiment, the monopole transmitter was activated with a low frequency pulse for the purpose of generating low frequency Stoneley waves. The transition between these two geological formations are clearly marked at 1 m.
