The paper presents the results of analysis of technical efficiency and economic performance of sidetrack drilling deep into the reservoir under conditions of late stages of development of productive areas of the Romashkinskoye field to target terrigenous Pashian and Bobrikovian-Radaevskian reservoirs. The interest to this problem is associated with gradual decrease in technical and economic efficiency of such operations and search for performance improvement opportunities.

Various factors that would affect efficiency of the technologies under consideration were investigated. These included geological and physical as well as geological and field conditions of particular production zones and deposits of the Romashkinskoye field. These studies enabled determination of optimal criteria for drilling target selection based on reservoir properties as well as optimize sidetracking strategies with account of specific geological and physical, and geological and field conditions.

Key words:

well intervention, sidetracking, horizontal lateral, successful, unsuccessful, breakeven point, correlation index, azimuth, deviation
