Objetivo This contract has as objective the development of techniques specific to reservoirs containing highly viscous oils or bitumens. On the industrial scale, it is intented to evaluate the potential of recovery methods combining injection of organic solvents and conventional thermal methods, and injection of hot fluids in-situ combustion.Major heavy oil resources remain unexploited owing to the inherent limitations to thermal recovery methods that are usually applied to them.The work concerned a range of 7 heavy crudes from a variety of origins and with densities of from 0.96 to 1.01.The selection of the various organic solvents was made in vivo in the light of their influence on the precipitation of the alsphaltenes present in the heavy crudes and the drop in viscosity related at one on the same time to the dilution of the crude by the solvent and the action of the temperature.From the standpoint of the in vivo measurements, a number of tests combining injection of solvent and in-situ combustion or injection of steam displayed significant effects.
