  • Mitigation of HS in steam injection technology using amines of natural origin
    Patent number: 9074122
    Abstract: A method for mitigation of H2S during a steam injection hydrocarbon producing process includes the steps of injecting steam and an additive comprising soluble molasses condensate (SMC) and amines of natural origin into a steam injection well; and producing hydrocarbons from a hydrocarbon producing well in subterranean fluid communication with the steam injection well, wherein the additive reduces H2S content in the hydrocarbon produced from the hydrocarbon producing well.
    Type: Grant
