SELF-SOURCED RESERVOIR FLUID FOR ENHANCED OIL RECOVERY.

摘要

Disclosed techniques include a method of obtaining an enhanced oil recovery fluid from a hydrocarbon reservoir, comprising producing a hydrocarbon stream (102) from the hydrocarbon reservoir (104), separating an associated gas stream (118) from the hydrocarbon stream (102), and condensing at least a portion of the associated gas stream (118) to obtain an enriched hydrocarbon fluid (124) suitable for injecting into a liquid layer (108) of the hydrocarbon reservoir (104) to enhance recovery of hydrocarbons from the hydrocarbon reservoir.
