Oil production decline in Russia can be explained by deterioration of its oil reserves. That is why the country pays much attention to development issues of high-viscosity oil fields of the Middle and Lower Carboniferous sediments. In this regard, using new chemical agents with combined effects and study of their impact mechanism has become of scientific and practical significance. This paper presents a laboratory physical simulation experiment to study reservoir performance after steam and chemical agent injectio...

At present, scale control through chemical inhibition is the preferred method in oil recovery though the principle of chemical agent action is still considered complex and not fully understood. An important issue that needs to be addressed is associated with compatibility of techniques and their impact on the reservoir and borehole zone. Scale control solutions remove deposits effectively and inhibit their formation, reducing costs associated with scale cleanup and disposal, while helping increase production and p...
