SYSTEM OF EXPANDING THE STORAGE CAPABILITY FOR GEOMECHANICAL ENERGY STORAGE
An expanded system and method for storing energy underground as high-pressure fluid in one or more subterranean zones and utilizing one or more wells. The wells may be connected to some or all of the subterranean zones which may be naturally occurring volumes in the rock structure, hydraulically fractured volumes in the rock structure, or hydraulically fractured an sealed volumes in the rock structure.
1 . A system for optimizing high-pressure fluid in a subterranean zone, the system comprising:
a working fluid storage mechanism to supply the fluid to the system;
a facility to pump and retain the fluid from said storage mechanism to said system;
three or more geomechanical subsystems in fluid communication with each other;
at least one of said subsystems being a subterranean zone adapted to receive and retain the fluid;
at least one of said subsystems being a wellbore; and
a fluid control device to control the fluid and optimize a system parameter.
2 . The system as defined in claim 1 wherein said device is within said facility.
3 . The system as defined in claim 1 wherein said device is within one of said subsystems.
4 . The system as defined in claim 1 wherein said storage mechanism is above a surface.
5 . The system as defined in claim 1 wherein said storage mechanism is one of said subsystems.
6 . The system as defined in claim 1 wherein said parameter is a fluid storage volume.
7 . The system as defined in claim 1 wherein said parameter is a fluid storage duration.
8 . The system as defined in claim 1 wherein said parameter is an injection rate.
9 . The system as defined in claim 1 wherein said parameter is a production rate.
10 . The system as defined in claim 1 whereon said parameter is an injection pressure.
11 . The system as defined in claim 1 wherein said parameter is a production pressure.
12 . The system as defined in claim 1 wherein said parameter is an idle pressure.
