Thesis Overview

The project titled "Analysis of Seismic Wave Attenuation and Velocity Anisotropy in Fractured Reservoirs using Shear-wave Splitting Techniques" aims to investigate and understand the behavior of seismic waves in fractured reservoirs through the application of shear-wave splitting techniques. Fractured reservoirs are complex geological formations that pose challenges in oil and gas exploration and production due to their heterogeneous nature. By analyzing seismic wave attenuation and velocity anisotropy, this study seeks to provide valuable insights into the subsurface characteristics of fractured reservoirs, which can enhance reservoir characterization and improve hydrocarbon recovery strategies. Seismic wave attenuation refers to the loss of energy as seismic waves propagate through subsurface formations, and it is influenced by various factors such as fluid content, rock properties, and fracture density. By studying the attenuation of seismic waves in fractured reservoirs, this research aims to quantify the impact of fractures on wave propagation and assess their contribution to reservoir heterogeneity. Velocity anisotropy, on the other hand, refers to the directional dependence of seismic wave velocity within a medium. In fractured reservoirs, the presence of fractures can introduce anisotropic behavior, leading to variations in wave velocity along different directions. By utilizing shear-wave splitting techniques, which involve analyzing the splitting of shear waves into fast and slow components upon encountering fractures, this study aims to characterize the orientation and density of fractures within the reservoir. The research methodology will involve the acquisition of seismic data from fractured reservoirs, processing and analyzing the data to extract attenuation and anisotropy information, and interpreting the results to gain insights into the subsurface structure. Advanced seismic imaging and inversion techniques will be employed to enhance the resolution and accuracy of the obtained results. The significance of this research lies in its potential to improve the understanding of fractured reservoirs and provide valuable information for reservoir management and field development planning. By accurately characterizing the seismic properties of fractured reservoirs, operators can optimize drilling and production strategies, mitigate risks associated with reservoir uncertainties, and maximize hydrocarbon recovery. In conclusion, the project "Analysis of Seismic Wave Attenuation and Velocity Anisotropy in Fractured Reservoirs using Shear-wave Splitting Techniques" addresses a critical aspect of geophysical exploration and reservoir characterization. Through the application of advanced seismic techniques and analysis methods, this study aims to contribute to the body of knowledge on fractured reservoirs and provide practical insights for the oil and gas industry.
