Abstract |
|
|
| In recent times, numerous oil and gas wells have experienced diverse failures ranging from downhole plug malfunctions to compromised well bore integrity, resulting in damage to aquifers, loss of assets, and posing significant economic and environmental hazards. The inclusion of the nano-silica into oil and gas well cement emerges as a promising solution, demonstrating a positive influence on enhancing mechanical properties such as compressive strength and durability. This research will provide a comparative analysis of cement slurry (15.8 ppg) performance, examining scenarios with and without the addition of nano-silica under downhole reservoir conditions. The experimental results reveal a substantial improvement in cement mechanical properties. when 3% by weight of cement (BWOC) nano-silica is introduced, however any percentage below 3 % had a negative impact on the cement sample compressive strength. Notably, this enhancement is attributed to accelerated cement hydration, ultimately leading to increased compressive strength and improved overall performance.
