Key words: monitoring, stream lines, allocation factor, injection efficiency, injection to withdrawal ratio.
This article reveals experience of applying stream line analysis for monitoring the development of the Vankorskoye oil-gas-condensate field. Regular stream line model updating is an indispensable condition for efficient applying of stream line analysis. Stream line analysis provides important quantitative information about water injection distribution, which is used for injection efficiency and allocation factors calculation. Then this data is exploited in calculating wells operating practices and planning reservoir pressure maintaining program.
