Abstract
A method of managing flow in a first producing well section when hydraulic fracturing a second well section includes reperforating the first producing well section to create a new set of perforations, pressurizing the formation through the new set of perforations, and pressurizing the formation through the second well section with a second amount of hydraulic fracturing liquid while the formation is still pressurized from the first producing well section.

A method of managing flow in a first producing well section when hydraulic fracturing a second well section, comprising:
- reperforating the first producing well section to create a new set of perforations;
- pressurizing the formation through the new set of perforations;
- pressurizing the formation through the second well section with a second amount of hydraulic fracturing liquid while the formation is still pressurized from the first producing well section.
A method of managing flow in a first producing well section when hydraulic fracturing an adjacent, second well section, comprising:
- closing off a first set of perforations in a first producing well section that was previously used to pressurize the formation through hydraulic fracturing where the first producing well section is adjacent to a second well section that has not been previously used to pressurize the formation;
- reperforating the first producing well section to create a second set of perforations in the first producing well section;
- pressurizing the formation through the second set of perforation in the first producing well section with first volume of hydraulic fracturing liquid;
- pressurizing the formation through the second well section with a second volume of hydraulic fracturing liquid while the formation is still pressurized from the first producing well section.
