Energy storage gained vital resource in the highly competitive energy market. The study looked at storing liquefied petroleum gas (LPG), in depleted reservoirs that have run dry. A synthetic reservoir model was built. It featured constant porosity and an initial oil in place of 0.25858E+09 STB. Also, it had an initial gas in place of 0.32839E+12 SCF using a numerical simulator. Different scenarios were simulated to assess reservoir behavior in various circumstances. LPG injection and production scenar- ios varied widely during tests. Results showed the potential benefits of using depleted reservoirs for LPG storage. Challenges remained regarding long-term viability. The research highlighted both successes and failures in the approach taken to store LPG effectively. Further studies could explore alternative methods for energy storage. The findings indicated that utilizing depleted reservoirs for LPG could have lasting impacts on energy management strategies moving forward. The study results provided fresh perspectives on storing LPG in empty reservoirs. Also, LPG had a unique response to pressure. It became clear that mon- itoring reservoir pressure was vital for the fuel performance. Further, the established technology demonstrated potential for testing with other energy fluids. Natural gas and hydrogen were among those tested. This opened up substantial and ecologically possibilities for energy storage
