Abstract
Improving the efficiency of hydrocarbon recovery from the subsurface largely depends on the development systems, technologies and quality of the productive strata opening. One of the methods for intensification of production and completeness of oil recovery is underbalanced drilling-in using horizontal and horizontal-branch wells. For these conditions the choice of flushing solution and regulation of its structural and rheological properties at a given level is fundamental.
