Structural tensor-based active contour method for 3D carving of fractured-cavity reservoirs
Siyao Li, Xuri Huang, Shuhang Tang · 2024
The fractured-cavity reservoirs within the dolomite formations of the Tarim Basin are highly advantageous. These fractured-cavity systems provide favorable space for the accumulation and migration of oil and gas. Carving these reservoirs contributes significantly to improving geological understanding and enhancing reservoir identification in the region. The structural tensor analysis based on post-stack seismic data can effectively identify the boundary features of fractured-cavity bodies. The 3D active contour segmentation method takes into account the spatial distribution relationship between points in the seismic attribute data, allowing for the effective delineation of the boundaries of fractured-cavity reservoirs. Combining these two methods allows for precise carving of fractured-cavity reservoirs, providing clear distribution and quantifying storage space, thereby enhancing the efficiency of geological interpretation work.
