The condensate blockage phenomenon is one of the known problems in the condensate gas reservoirs which, by increasing production from one Condensate gas reservoir occurs due to the pressure drop near the well-bore. This phenomenon leads to a reduction in gas production and a drop in the pressure required for production. From Effective solutions to unblock the condensate blockage in gas condensate reservoirs, modification of reservoir rock wettability from liquid-wet to gas-wet. In the tests related to wettability alteration of the reservoir rock, first before the chemical coating of the reservoir rock, the contact angle for the three systems of water-air, oil-air and condensate-air measured Which resulted in 0°, 15° and 0°, respectively. Then the contact angle test in the presence of concentrations 0.3% and 0.8% volumes of (3-Aminopropyl)triethoxysilane (APTES) and 500 ppm and 2000 ppm of Modified Nano-silica was performed. Depending on the contact angle test performed for both surface modifiers, APTES and modified Nano-silica, the best performance for the water-air system was related to a concentration of 500 ppm of modified Nano-silica with Change 127° in contact angle. For the oil-air system, the improvement in the angle of contact in the presence of all concentrations is negligible, which can be neglected. Also for the condensate-air system is also nothing any improvement in the angle of contact. Today, natural gas, which is a clean and inexpensive fuel, is known as a source of energy supply. For reservoirs that have low to moderate natural gas content and the gas transmission distance is not high, hydration of natural gas is a suitable method for gas transfer. In the experiments related to hydrate formation, the effect of additives that play a role in improving the storage of gas during the process of carbon dioxide hydrate formation has been investigated. In this experiment, the effect of three concentrations of 0.3%,0.5% and 1% volumes of APTES and five concentrations of 0.05%, 0.1%, 0.15%, 0.2% and 0.25% by weight of modified Nano-
