The Mississauga Formation in Penobscot, Nova Scotia, Canada, represents a promising yet challenging frontier for oil exploration. This study employs an integrated approach combining lithological and petrophysical analyses of well logs to overcome the inherent complexities of subsurface characterization. Leveraging advanced well log data, this research aims to enhance our understanding of the Mississauga Formation's geological composition and petrophysical properties, crucial for successful oil exploration. The investigation integrates diverse well log data, including gamma-ray, resistivity, porosity, and sonic logs, to construct a comprehensive lithological model. By synergizing these datasets, the study seeks to delineate lithological variations, identify potential reservoir zones, and map geological structures within the Mississauga Formation. Petrophysical analyses further contribute to characterizing the rock's physical properties, enabling a refined assessment of reservoir quality and fluid saturation. The outcomes of this research offer valuable insights into the subsurface intricacies of the Mississauga Formation, aiding in the identification of optimal drilling locations and enhancing reservoir management strategies. Additionally, the integrated approach presented in this study serves as a crucial tool for mitigating exploration risks, optimizing resource recovery, and fostering sustainable oil exploration practices in Penobscot, Nova Scotia, Canada.
