Complexity of geological conditions within the Northern flank of the West Kuban trough, due primarily to the sharp hydraulic differentiation of the section and reveal the presence of areas, incompatible drilling conditions, places high demands on decision making rationale and the choice of well structures in the design of exploratory drilling. Adverse surface conditions that slow down the involvement of hydrocarbons in industrial development, determine the ubiquity of advanced methods of commissioning until the completion of the exploration phase. This article describes the most typical geological problems encountered during drilling within the Northern flank of the West Kuban trough, measures for their prevention, as well as some specific features of the wiring holes that are in different surface conditions and at different stages of development of hydrocarbon deposits. The conclusions drawn from the results of the work indicate that, despite the complexity of geological conditions, compliance with design decisions, laid down in the regulations, in conjunction with the timely correction of the last stage of drilling, can effectively carry out accident-free wiring wells in Chokrak deposits in the Northern flank of the West Kuban trough.
