4.1.4 Requirements for injected water
Industrial implementation of secondary extraction
methods and techniques to maintain reservoir pressure by
waterflooding in the oil reservoir is closely associated with finding
appropriate sources of supply. Consumption of water during
3
flooding is 1.5-2 m of water per 1 ton of oil produced. However,
3
under pattern flooding depleted reservoirs need 10-15 m of water
per 1 ton of oil produced. Therefore, the question is, to have a
source of water supply. At the same time as the issue is not only
the quantity but also the quality of water.
Under flooding oil deposits could be used the following
sources of water:
