    Abstract: A low-viscosity cement composition, useful for use in the sector of oil drilling, contains cement, water and an additive obtained by salifying, into the alkali-metal, alkali-earth metal, or ammonium, salts, the sulphonated and oxidated products deriving from the reaction between sulphur trioxide and cokery tar, or fuel oil from steam cracking.
    Such a cement composition is endowed with improved rheological characteristics, and, in particular, with a low viscosity value, without any substantial changes in the pumping times, even at high temperatures and pressures.
