Application of Seismic Noise Interferometry to Extract High-Resolution P-Wave Reflectivity from Hydraulic Fracturing Data
Abstract
This study demonstrates the successful application of passive seismic interferometry, specifically through the autocorrelation function, to extract high-resolution P-wave reflections from seismic data acquired during hydraulic fracturing. This application demonstrates the efficacy of extracting high-resolution P-wave reflectivity using hydraulic fracturing-induced seismic noise, a previously underexplored source for exploration-scale imaging. Stacking these reflections allows the construction of seismic sections at zero offsets. Typically, this technique uses data based on environmental noise and earthquakes. However, this study used measurements obtained during hydraulic fracturing in the Potiguar Basin of Northeast Brazil. We applied a processing sequence that included the Gaussian Smoother Filter to generate a smoothed amplitude spectrum and to extract the best body-wave component of Green’s function. We whitened the spectrum to remove any unwanted effects from the sources. The resulting seismic sections were compared with seismic lines acquired near the study area and interpreted in light of the available geological information. The seismic images were constructed in 2D and projected into 3D, with reflectors exhibiting high resolution and lateral continuity. Deeper reflectors align well with available geological and geophysical data; however, validation of the shallowest boundaries remains limited by the absence of high-resolution reference data in this area.
