Reservoir Simulation
The simulation results indicate that fluid displacement efficiency varies significantly with different extraction techniques. The following observations were made:
-
Natural drive mechanisms resulted in recovery efficiencies of around 25-30%.
-
Water flooding increased recovery efficiency to approximately 45-50%.
-
Chemical injection methods further improved efficiency to 60-65%.

Discussion
The laboratory results provide valuable insights into the properties and behaviors of petroleum in different contexts. The porosity and permeability analysis helps in understanding the nature of reservoir rocks, which is critical for planning extraction operations. The reservoir simulation results highlight the importance of selecting appropriate recovery methods to maximize production efficiency.
Furthermore, the refining process results demonstrate that although distillation yields the highest amount of product, the quality is comparatively lower. Advanced refining techniques like catalytic cracking and reforming are essential to producing high-quality fuels, even though they might result in lower yields.
Conclusion
This lab report presents the findings from various petroleum engineering experiments and simulations that contribute significantly to the field. By analyzing core samples, simulating reservoir behaviors, and evaluating recovery methods, we can make informed decisions that enhance petroleum production and refining processes. Future research should focus on optimizing these methods and exploring new technologies to further improve efficiencies.
