| titleOfInvention | A process for the enhanced recovery of petroleum oil |
| abstract | A process for the recovery of petroleum oil from a producing formation, the oil being withdrawn from the formation through a production string, which process comprises the steps of: # chemically characterizing ion-containing water produced by said formation and, by theoretical simulation, estimating the precipitation potential when precursor ions present in sea water are contacted with said ions-containing water such that scale would be produced in the formation and in said production string when in contact with the sea water in order to establish the optimum ratio of sea water to formation water which would yield treated water having the lowest possible content of precursor ions so as to avoid precipitation when the treated water is contacted with said ion-containing water; # preparing said treated water by mixing under agitation sea water which contains precursor ions and ion-containing formation water, so as to precipitate at least a portion of said precursor ions and filtering the resulting precipitate; # injecting said treated water into the producing formation in order to displace the petroleum oil from the producing formation; and # recovering the petroleum oil. |
