Beyond Surface Imaging: Acoustic Deep Shear Wave Imaging Bridges the Gap for Accurate Fracture Detection and Mapping

Abstract

Abstract Accurate fracture detection and mapping is essential for optimizing hydrocarbon production and avoiding early water breakthrough through fractures. However, conventional surface seismic methods and borehole shallow resistivity imaging have limitations in detecting deep fractures, which can lead to inaccurate reservoir characterization. This paper presents the application of Acoustic Deep Shear Wave Imaging (DSWI) for bridging the gap between the surface seismic and borehole shallow resistivity imaging data for accurate fracture detection and mapping, to avoid early water breakthrough through these fractures. DSWI is a new imaging technology that uses shear waves to image the subsurface. Shear waves are sensitive to fractures and can provide detailed information on their orientation, size, and distribution. By combining the DSWI data with the surface seismic and borehole shallow resistivity imaging data, a more accurate image of the subsurface can be obtained, allowing for more accurate fracture detection and mapping. The accurate detection and mapping of fractures can help avoid early water breakthrough through the fractures. By identifying the high permeability pathways, these fractures can be avoided and isolated, allowing for more effective reservoir management and optimization of hydrocarbon production. The application of DSWI has several advantages over traditional imaging methods. DSWI can provide a more accurate image of the subsurface, allowing for more accurate fracture detection and mapping. In addition, DSWI can image deeper fractures that are not visible with conventional imaging methods. In conclusion, the application of DSWI is a powerful tool for accurate fracture detection and mapping in the subsurface. By bridging the gap between the surface seismic and borehole shallow resistivity imaging data, a more accurate image of the subsurface can be obtained, allowing for more effective reservoir management and optimization of hydrocarbon production. The accurate detection and mapping of fractures can help avoid early water breakthrough through the fractures, and improve the overall productivity of the reservoir.
