In this scenario, Detail Logs would be crucial for accurately characterizing the reservoir and understanding its potential. Here's how they could benefit the analysis:

• **Fault Interpretation:** Detail Logs provide a magnified view of the formation, allowing for precise mapping of the complex fault network. This detailed information helps to accurately delineate fault blocks, identify potential zones of hydrocarbon entrapment, and understand the overall structural complexity of the reservoir.
• **Thin Bed Identification:** Standard logs might struggle to differentiate thin sandstone layers from surrounding shale. Detail Logs, with their larger scale depth, can accurately delineate the boundaries of these thin beds, helping to identify potential reservoir zones and understand their distribution within the fault blocks.
• **Porosity and Permeability Analysis:** Detail Logs, particularly those measuring properties like sonic and density, can provide more accurate data on porosity and permeability within the thin sandstone layers. This information is critical for assessing the quality of the reservoir and its potential for hydrocarbon production.
• **Drilling Optimization:** Detailed log data can help guide the placement of wells within the fault blocks, optimizing drilling strategies to maximize hydrocarbon recovery from the thin sandstone layers. They also aid in identifying the optimal well trajectory to avoid faults and ensure effective reservoir drainage.

By using Detail Logs, you can overcome the limitations of standard logs and gain a more accurate and detailed understanding of the complex reservoir structure and thin bed formations. This allows for better evaluation of the reservoir's potential and informed decision-making regarding exploration and production strategies.
