In the article the design of cluster drilling of one hypothetical offshore oil field is considered. Based on the development project for this field, 91 wells are required to be drilled. According to the adopted coordinate system, the coordinates of the faces of all wells were measured with a ruler in the structural map, and the parameters of the wellbore profiles were also determined as the vertical depths of the faces of the wells, their deviations from the vertical, and others. Based on these parameters, the total lengths of the boreholes of all wells and the total costs of their full construction were calculated. The rational coordinates of the stationary platforms, the total area of the work sites, as well as the total costs for their construction at sea, were also calculated; in each variant, optimal flyover schemes were chosen, their total lengths, as well as total costs, were calculated. Based on all the data obtained, the total costs for cluster drilling of all wells were determined, as well as the costs for the construction of all hydraulic structures. Among all the accepted 8 options, only one II option turned out to be the most rational, requiring minimal investment.
