ABSTRACT:
The invention relates to a composition for use in the extraction of oil and to a method of extracting oil using the composition. The composition comprises components A, B and C in which: A is a first solid hydrophobic material which is in-soluble in an organic solvent selected from light fractions of petroleum, distillate, kerosene, acetone, gasoil, hexane, benzene and condensate; B is a second hydrophobic material which is either soluble in or can be emulsified with an organic solvent selected from light fractions of petroleum, distillate kerosene, acetone, gasoil, hexane, benzene and condensate; and C is a retention improving material comprising a mineral material. A solvent, D, is added before the composition is used to treat an oil well. In oil well systems in which water or surfactant is pumped into the stratum through an injection well under pressure so that petroleum is forced from the rock stratum into the bottom hole zone of an extraction well, the composition is added to the extraction well.
