Wavelet Analysis was used to study fracturing pressure data from different formations to improve future stimulation practices. The technique breaks down the pressure signals into different components to analyze them individually. By examining the detail coefficients, researchers were able to detect changes in pressure related to proppant injection and screen-out events. This method can help in early detection of potential issues during fracturing treatments. Comparing the results with the Moving Reference Point technique showed that Wavelet Analysis provides a more accurate estimate of fracture propagation characteristics. This study demonstrates the effectiveness of using Wavelet Analysis as a diagnostic tool in analyzing fracturing pressure data.
