Key words: switching time to injection mode, regular patterns, technical and economic model.

The objective of the present work is to develop a methodology for determining of switching time to injection mode, which maximizes the economic effect in terms of cumulative discount production. The methodology is based on the techno-economic model of oil reservoirs development by regular patterns of vertical wells or vertical wells with fractures including the effect of switching wells to injection and allows to define optimal switching time for the given parameters of the well pattern, the filtration properties of the reservoir and the discount rate.
