The recovery of residual oil via nanosystem appliance
V.M. ShamilovThe increase of efficiency of reservoir stimulation is observed as it was conducted via nanosystem in water injection process made in the result of carried out experimental studies and field-test surveys. The physical-chemical processes taking place in the border of phase division lead to the increase of oil recovery factor in the result of using metallic nanoparticles composition (Cu 50–70 nm) and surface-active agent sulphanol. The appliance of this technology in many oil fields of Azerbaijan, specifically in the horizons, where water injection is actual, lead to the rise in oil production for 21 % in the well under stimulation and to the decrease of water in produced liquid for 13 %.
