Title:
HYDROCARBON RECOVERY METHOD AND HYDROCARBON RECOVERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/003648
Kind Code:
A1
Abstract:
A hydrocarbon recovery method that recovers a production fluid containing hydrocarbons from a production well provided in the seabed inhabited by microorganisms that generate carbon dioxide or sulfate ions for promoting the precipitation of calcium carbonate, wherein the method has: an insertion step of inserting a composite used by microorganisms in the generation of carbon dioxide or sulfate ions into the production well; a pressure reduction step of reducing the pressure inside the production well after the composite is inserted; and a recovery step of recovering hydrocarbons with the pressure inside the production well reduced.
