The article is devoted to perspective direction of carbonate reservoir acid treatment by non-polymeric self-diverting acid compositions. Non-polymeric self-diverting acid compositions on the basis of the viscoelastic surfactants  and the specially designed acid composition are offered. These acid compositions provide a uniform stimulation of all areas of the reservoir, the creation of high-conducting dominant wormhole maximum length and do not cause colmatation of bottom-hole formation zone.
