USE OF THERMAL ENERGY OF THE FORMATION

Abstract

The physicochemical principles of selection implemented in ICH compositions have been further developed in the development of physicochemical reservoir stimulation methods, in which the thermal energy of the reservoir or injected coolant is used for the in-situ generation of alkaline buffer systems, CO2, and for the formation of freely and cohesively dispersed systems (inorganic gels and sols) that enhance oil displacement and formation coverage by flooding. The scientific basis for these methods is the results of studies on the kinetics of hydrolysis and gelation in the aluminum salt, urea, surfactant, water, and rock system.
