Abstract

In the main Accumulation of the Bavlinskoye oil field, twelve wells have been producing from the Pashiyan reservoirs since 1954, each with cumulative oil production over 1 mln tonnes. Several factors facilitated successful operation of the wells: favorable geological setting while drilling, timely water shutoff and EOR operations, waterflooding control and change of fluid flows, displacement of injection front into the periphery to divide the reservoir into water-oil and oil zones and to create a closed waterflooding system and an additional spot waterflooding for targeted stimulation of low-producing intervals.

Key words:

siltstone, sandstone, producing rows of wells, oil production, watercut, waterflooding control, cyclic waterflooding, bottomhole flushing, spot waterflooding
