Abstract
A method of protecting a first well from stimulation fluid of a second well includes shutting in the first well; starting injection of natural gas into the first well to increase a pressure of the first well; treating the second well using a stimulation fluid after starting natural gas injection; and stopping injection of natural gas.
Claims22
A method of protecting a first well from stimulation fluid of a second well, comprising:
- shutting in the first well;
- starting injection of natural gas into the first well to increase a pressure of the first well;
- treating the second well using a stimulation fluid after starting natural gas injection;
- and
- stopping injection of natural gas.
A method of protecting a producing well from stimulation fluid of a treatment well, comprising:
- injecting natural gas into the producing well to increase a pressure of the producing well and fractures in communication with perforations of the producing well;
- and
- fracturing the treatment well after injecting natural gas.
A method of protecting a producing well from stimulation fluid of a treatment well, comprising:
- producing hydrocarbon from the producing well;
- shutting in production of the producing well;
- injecting natural gas into the producing well after shutting in the producing well, thereby increasing a pressure of the producing well;
- and
- fracturing the treatment well after injecting natural gas.
