Pressurizing and protecting a parent well during fracturing of a child well

摘要

A method for protecting a wellbore includes identifying a parent wellbore and a child wellbore and identifying a parent well stage along the parent wellbore that has the potential to interact with a child well stage along the child wellbore while the child well stage undergoes hydraulic fracturing. The method further includes pumping a treatment fluid downhole to the parent well stage for pressurizing the parent well stage to a pressure that is equal to or greater than the pressure in the child well stage while the child well stage undergoes hydraulic fracturing and maintaining the pressure in the parent well stage that is equal to or greater than the pressure in the child well stage while the child well stage undergoes hydraulic fracturing.
