The assessment of the state of the "Deposit - underlying water basin" system, the amount and influence of gases dissolved in the bottom water on the Deposit, the forecast of the direction of exchange processes and water introduction processes that will occur when the pressure in the deposits decreases during field development is very relevant. A serious problem in the development of gas condensate or oil fields is the presence of associated water in the produced reservoir commercial products. A constant increase in the amount of produced water during the operation of productive wells in oil and gas condensate fields is caused by the arrival of a mixture of condensation water (VGF) in various combinations with bottom water that penetrates the bottom of the well from underlying or overlying deposits in the presence of leaky wells. The introduction of reservoir waters into deposits is possible through local fractured zones and faults. The presence of such zones and tectonic disturbances is recognized by most researchers, as well as proven by well drilling data and seismic studies. Wells are flooded very quickly if they are laid in the immediate vicinity of faults.

Key words: Deposit, gas, water, fault, flooding, pressure
