compensation. There are factors of current and accumulated
compensation.
A factor of current compensation - is the ratio of injected
water to flowrates liquids that are selected, reduced to formation
conditions per unit of time (year, month, day and etc.)

where Q inj - volume flowrate injected water under standard
conditions; b w – volume formation factor for the injected water
(b w1,01); Q oil - volume flowrate for the oil under standard
conditions; boil – volume formation factor for the oil; Q w - volume
flowrate selected water under standard conditions; b w‟ - volume
formation factor for the selected water, which is different from the
volume formation factor for fresh water; Q los – loss of water that
escapes the contour; k - factor for the loss of water in the periodic
work injection wells, under breaks in water lines and other
technological reasons. This ratio is assumed to be k = 1,1-1,15.
A factor of current compensation shows how forcing
compensated selection at any given time. According to the current
values of the coefficient, compensation can make the following
conclusions. If m cur < 1 injection behind the selection and expect
the average formation pressure should drop. If m cur > 1 injection
exceeds the selection and the formation pressure should rise. When
m cur = 1 should have been the stabilization of the current formation
pressure at the current level, no matter what it was in early
development.
A factor of accumulated compensation is the ratio of
injected water to flowrates liquids that are taken to the
consolidated formation conditions during the whole period of
injecting
