A method for upgrading the viscoelastic properties of a heavy oil by altering its elastic modulus. An effective amount of one or more elastic modulus lowering agents are used, wherein preferred elastic modulus lowering agents include mineral and organic acids and bases, preferably strong bases, such as hydroxides of metals selected from the alkali and alkaline-earth metals.
L'invention concerne un procédé qui permet d'améliorer les propriétés viscoélastiques d'un pétrole lourd en modifiant son module d'élasticité. Selon l'invention, on utilise une quantité efficace d'au moins un agent réducteur de module d'élasticité, les agents réducteurs de module d'élasticité préférés comprenant des acides et des bases minéraux et organiques, de préférence des bases fortes, telles que des hydroxydes de métaux choisis parmi les métaux alcalins et alcalinoterreux.
