Abstract
A method and a system for pressurizing a reservoir volume including fluid in a formation with a parent well extending through the formation includes storing liquefied natural gas (LNG) at an on-site location of the parent well, de-liquefying the LNG to form natural gas at the on-site location, and injecting the natural gas into the parent well to pressurize the reservoir volume through the parent well.
Claims18
A method for pressurizing a reservoir volume including fluid in a formation with a parent well extending through the formation, the method comprising:
- storing liquefied natural gas (LNG) at an on-site location of the parent well;
- de-liquefying the LNG to form natural gas at the on-site location;
- injecting the natural gas into the parent well to pressurize the reservoir volume through the parent well;
- drilling a child well after pressurizing the reservoir volume through the parent well;
- wherein injecting the natural gas into the parent well to pressurize the reservoir volume decreases asymmetric fracturing towards the parent well during stimulation of reservoir volume through the child well.
A system for pressurizing a reservoir volume including a fluid in a formation with a parent well extending through the formation, the system comprising:
- a source of liquefied natural gas (LNG) located at an on-site location of the parent well, wherein the on-site location of the parent well is near a site of a child well to be drilled through the reservoir volume;
- a cryogenic system located at the on-site location and comprising a pumping unit and a heating unit configured to de-liquefy the LNG to form natural gas;
- and
- injection equipment connected and in communication with the parent well and configured to inject the natural gas into the parent well to pressurize the reservoir volume through the parent well before drilling and stimulation of the child well.
