The main results of pilot operations on Russkoye Field during 2010 – 2013 are given. The article presents a description of the features of well test interpretation in such complex geological and physical conditions: inability to achieve late radial flow, lengthy borehole impact, changes in the state of near-wellbore zone and horizontal borehole during studies, complex geomechanical and borehole effects, and formation of man-induced channels of primary flow. The authors propose approaches to planning, execution, and interpretation of complex studies allowing to obtain the maximum information to support further development.
