high levels of oil production for a longer period. The duration of
the stage - 5-7 years, with the larger oil viscosity, the shorter
duration of the second stage.
The third stage (stage falling production oil) is
characterized by intense slowdown rate development, progression
to the product water content of 80-85%. Because water content is
reduced through disconnection well stock wells, almost all the
amount of well transferred to a mechanized method of operation.
The main task of this stage - slow down the fall in oil production.
The main objectives are to reduce the production of
formation of water through insulation work. The duration depends
on the stage of preliminary stages and durations of 5-10 years or
more.
The fourth stage (final stage of development) is
characterized by slow rate development. Amount of water in oil is
high and slowly increases decreases operating well stock. During
this stage carry large amount of repair work. The duration of the
fourth stage of 15-20 years and more.
Formation pressure P f - the pressure at which oil and
gas are found in the reservoir.
Amount of wells n - the total amount of injection and
production wells that are designed to carry out the development
process. The number of wells divided into primary and backup.
Gas-oil factor (gas-oil ratio) G - the ratio of the
extracted gas to the amount of oil produced
