Enhanced oil recovery by changing wettability using nanoparticles

In this paper, to s tudy the impact of nanoparticles and to inves tigate various factors such as time, temperature and concentration of nanoparticles in order to change Reservoir rock wettability is discussed. For this purpose, the contact angle of oil droplets near oil rock water as an indicator for the change of reservoir rock wettability was determined at different time and place intervals. By comparing the results, the contact angle can be seen. Water and oil saturated rocks with petroleum wettability after exposure to silicon nanofluids relative to alumina, they mos tly change to hydrophilic wettability. In these experiments, after centering the nanoparticles and modifying their surface using bonding of nanofluids are prepared and carbonate rock is placed in the nanofluid and the wettability of the rock changes by measuring the angle. The contact of oil droplets with rock is inves tigated in its presence. The results showed that these nanoparticles have the ability to change the wettability of carbonate rock from they are oil-friendly to hydrophilic and can be used to increase oil extraction.
