HYDROGEN CAVERN PAD GAS MANAGEMENT |
| 摘要 |
A method of pad gas management in an underground storage volume including storing a first compressible fluid, determining a transient minimum operating pressure (Ptrans), measuring the pressure (Pact), removing at least a portion of the first compressible fluid, concurrently, introducing an incompressible fluid, thereby producing a transient pressure condition controlled by the flow rate of the incompressible fluid, such that Ptrans<Pact. The method may also include a length of casing, permanently cemented into the surrounding rock formations, with a final cemented casing shoe defining the practical endpoint at an approximate depth (Dcasing), determining a transient pressure gradient (Gtrans) for the underground storage volume, wherein Ptrans<Dcasing×Gtrans. The maximum removal of the first compressible fluid is controlled such that Pmin<Pact, and wherein the transient pressure condition has a duration (D) of less than 7 days, more preferably less than 5 days. |

1. A method of pad gas management in an underground storage volume, comprising:
storing a first compressible fluid in an underground storage volume, determining a transient minimum operating pressure (Ptrans) for said underground storage volume, measuring the pressure (Pact), of said underground storage volume, removing at least a portion of said first compressible fluid from said underground storage volume, concurrently, introducing an incompressible fluid into said underground storage volume, thereby producing a transient pressure condition,wherein the transient pressure condition is controlled by the flow rate of said incompressible fluid, such that Ptrans<Pact. |
