Unlocking Subsurface Insights: Advanced Seismic Denoising with DAM-TV
Seismic data processing is paramount for geological exploration, yet noise frequently compromises data quality, obscuring critical features. Traditional denoising methods struggle with complex directional events and preserving curvilinear structures. Our innovative Directional Adaptive Mode Total Variation (DAM-TV) method directly addresses these challenges, delivering superior noise attenuation while maintaining structural integrity.

Overcoming Seismic Noise Complexities
Seismic data acquisition is frequently compromised by noise, which can obscure critical geological features and diminish the accuracy of subsequent interpretations. High-quality noise-free data are essential for advanced inversions. Traditional Total Variation (TV) methods, while preserving edges, often suffer from the 'staircase effect' and struggle with oscillatory noise or weak features. Directional TV (DTV) is limited when multiple dominant directions are present in complex curvilinear events, making it challenging to balance noise removal and structural preservation.
Directional Adaptive Mode Total Variation (DAM-TV)
DAM-TV introduces a novel approach by decomposing 2D seismic data into k distinct modes. Each mode uk is processed with a Directional Total Variation (DTV) regularization tuned to its dominant direction θk. The model is formulated via convex optimization, incorporating spatially varying directional modes. An Augmented Lagrangian method iteratively optimizes modes and directional fields. Crucially, a Canny edge detector guides the evaluation, ensuring adaptive DTV smoothing preserves broken curve edges and structural integrity.
Enhanced Fidelity & Multi-Directional Adaptability
The core innovation of DAM-TV lies in its ability to adaptively handle multiple dominant directions and preserve the curvilinear nature of complex seismic events. By optimizing directional TV per mode and utilizing gradient optimization, DAM-TV achieves higher SNR and superior edge preservation. This prevents the 'staircase effect' and effectively reconstructs complex geometric features like crossing faults and curved events, which other methods often blur or distort. The result is a robust method balancing noise suppression with critical geological feature preservation.

Enterprise Process Flow
Real-World Performance on Complex Seismic Data
Applying DAM-TV to real seismic data with weak events and multiple directional orientations demonstrated its superior ability to retain subtle reflections, such as faint horizontal layers, and complex curvilinear structures. The method effectively removed noise without oversmoothing, which is critical for accurate geological interpretation. Canny edge detector analysis highlighted DAM-TV's robust edge preservation, reconstructing geometric shapes with high fidelity and achieving an edge map closest to the ideal noise-free version compared to wavelet, DTV, and SGMD.
Balancing Quality with Computational Efficiency
While DAM-TV (average runtime 147s) is more computationally intensive than methods like wavelet (25s) or DTV (90s), this cost is justified by significant advantages in denoising quality for complex multi-directional structures. The ADMM framework, while iterative, ensures robust optimization. This trade-off between reconstruction quality and runtime is a key consideration for time-sensitive enterprise applications.
