ABSTRACT:
Particular hydrocarbon composition constituted by saturated species, alkylbenzenes and polyaromatics, useful for dissolving asphaltenic residues present in oil wells. Such useful hydrocarbon blends for dissolving asphaltenic residues present in oil wells, are characterized in that said blends are essentially constituted by a composition selected from those which, on a ternary chart, in which the vertex (A) represents 100% of polyaromatics with z<-6, the vertex (B) represents 100% of saturated species, and the vertex (C) represents 100% of alkylbenzenes with z=-6, are comprised between:
