METHOD OF REDUCING WATER INFLUX INTO GAS WELLS |
摘要 |
A method of reducing water influx into a wellbore, wherein the wellbore is i n fluid communication with a subterranean formation such as a gas producing formation or gas reservoir. The method particularly places a gelant in a desired position down the wellbore and into the formation in order to thereb y reduce the influx of water and enhance the resulting gas production. The method includes the steps of first introducing a gelant into the wellbore an d second introducing a temporarily stable foam into the wellbore in order to overdisplace the gelant from the wellbore and into the formation.
