  • Hydrocarbon recovery method and hydrocarbon recovery system
    Patent number: 10914151
    Abstract: A hydrocarbon recovery method for recovering a production fluid containing hydrocarbons from a production well provided in the seabed in which microorganisms that produce carbon dioxide or sulfate ions for promoting a deposition of calcium carbonate exist, the method includes: an injecting process of injecting, into the production well, a composition used for producing carbon dioxide or sulfate ions by the microorganisms; a decompressing process of decompressing an inside of the production well after the composition is injected; and a recovering process of recovering the hydrocarbons in a state in which the inside of the production well is decompressed.

  • INFORMATION PROCESSING DEVICE AND COMPUTER READABLE MEDIUM
    Publication number: 20200050783
    Abstract: A table determination unit performs a table determination process, when an access request occurs, of determining presence/absence of access authority by referring to an authority table. A code determination unit performs a code determination process, when the access request occurs, of determining presence/absence of the access authority by executing a determination code to determine presence/absence of the access authority. An access control unit allows access in a case where it is determined by the table determination process that the access authority is present and it is determined by the code determination process that the access authority is present.
