Abstract
A cavern pressure control method includes storing compressible and possibly incompressible fluids in an underground storage volume, removing a portion or introducing additional incompressible fluid into the underground storage volume, possibly removing a portion or introducing additional compressible fluid into the underground storage volume, thereby producing a net pressure increase rate (Pinc) within the underground storage volume, wherein Pinc is maintained at less than a predetermined maximum increase value (PImax).
Claims9
A method of pressure management in an underground storage volume, comprising:
- storing a compressible fluid in an underground storage volume,
- storing an incompressible fluid in said underground storage volume,
- and introducing additional compressible fluid into said underground storage volume, thereby producing a net pressure increase rate (Pinc) within said underground storage volume,
- wherein Pinc is maintained at less than a predetermined maximum increase value (PImax), wherein PImax is 100 psi/hr, wherein said compressible fluid is hydrogen.
