Abstract
A process for increasing recovery of oil from oil-bearing earth formations wherein H.sub.2 S from sour wellhead gas is oxidized to SO.sub.3 which in turn is reacted with a petroleum hydrocarbon mixture to produce a petroleum sulfonate. The petroleum sulfonate is incorporated into an oil recovery enhancing fluid and introduced through an injection well into an oil-bearing earth formation to displace oil toward a production well.
