Gas deposit water cut – natural geo-technological intra-formational process of reservoir water influx into the gas-saturated part of the deposit from the adjacent reservoir water-drive system.

Deposit water cut process is characterized by a series of effects having significant impact on the efficiency of the designed development plans and on the volume of recoverable gas reserves. Reservoir water influx into the deposit has both negative and positive consequences. Negative consequences are associated with decrease of the recoverable gas reserves and with complications of wells operation (leading as far as shutdown). Positive consequences are associated with slowing down the rate of reservoir pressure drop in the gas part of the deposit due to incoming reservoir water. This makes it easier to supply gas into the pipeline.
