Abstract
Summary
in order to increase production from tight reservoirs with heavy oil we recommend deep selective thermochemical stimulation of reservoir. we use mini hydro-fracturing equipment; a tube with a membrane which tears during 25 atm pressure to create a mechanical shock to break formation and then injection of binary mixture in new created fractures. the products of decomposition of binary mixture are nitrogen, oxygen, steam and heat. these production will open new fracture and increase formation temperature and help to increase oil production by improving permeability and oil mobility.
