Thesis Overview

The research project titled "Seismic Imaging and Characterization of Subsurface Fractures in Unconventional Reservoirs" aims to address the significant challenge of accurately identifying and characterizing subsurface fractures in unconventional reservoirs using seismic imaging techniques. Unconventional reservoirs, such as shale formations, have become increasingly important sources of hydrocarbons, but their complex geological structures, including natural fractures, pose challenges for effective exploration and production. The research will begin with a comprehensive review of the existing literature on seismic imaging and fracture characterization in unconventional reservoirs. This review will provide a solid foundation for understanding the current state-of-the-art techniques, challenges, and gaps in knowledge in this field. The methodology chapter will outline the specific seismic imaging techniques and data acquisition methods to be utilized in the research. This will include details on the seismic survey design, processing workflows, and interpretation methodologies tailored to the identification and characterization of subsurface fractures. The core of the research will be the analysis and discussion of the findings from the seismic imaging data. Advanced seismic attributes and analysis techniques will be applied to detect and characterize subsurface fractures, providing insights into their orientation, density, and connectivity within the reservoir. The results will be compared with existing geological models and well data to validate the effectiveness of the seismic imaging approach. The significance of the study lies in its potential to improve the understanding of subsurface fractures in unconventional reservoirs, leading to more accurate reservoir characterization and enhanced hydrocarbon recovery strategies. By utilizing advanced seismic imaging technologies, the research aims to contribute to the development of more efficient and sustainable exploration and production practices in unconventional reservoirs. In conclusion, the research project on "Seismic Imaging and Characterization of Subsurface Fractures in Unconventional Reservoirs" seeks to advance the knowledge and capabilities in seismic imaging for fracture characterization, with a specific focus on unconventional reservoirs. The findings and insights generated from this study have the potential to benefit the oil and gas industry by enabling better reservoir management decisions and improving overall production efficiency in challenging subsurface environments.
