摘要： Acoustic anisotropy of downhole formations is determined using statistical analysis. During operation of a downhole system, acoustic slowness measurements are acquired around a borehole extending along a formation. Statistical analysis is performed on the acquired slowness measurements, whereby the maximum and minimum slownesses of the formation are determined.

摘要： An acoustic tool, system, and method for performing down-hole measurements. An encoded pulse sequence is transmitted from an acoustic tool. First reflections are received from the encoded pulse sequences. The first reflections from the encoded pulse sequence are identified from a number of reflections of the encoded pulse sequence. Measurements are performed utilizing the first reflections of the encoded pulse sequence. Other systems and methods are presented.

摘要： A method and system of performing quality control for a downhole tool. An acoustic source is employed to generate a Stoneley wave, and acoustic receivers generate signals indicative of the Stoneley wave. A reference value is calculated from the signals to assess the quality of the receivers. The reference value may be for a selected receiver or a selected receiver ring. The reference value is compared to a threshold deviation to determine if the reference value is outside the threshold deviation. If the reference value is outside of the threshold deviation, the deviation for one of the selected receiver or the selected receiver ring is corrected.
