Abstract
The present invention relates to a colloidal composition for stimulating the operation of high water-yield, natural gas, or petroleum-producing wells, which, when mixed with the water, forms a structured high viscosity barrier to exclude the water and to reduce the water/hydrocarbon volume proportion of the production, furthermore, at the time of use, in the proximity of the wells the residual oil sorbed on the surface of the hydrocarbon reservoir and/or the residual oil trapped in the pores of the hydrocarbon reservoir becomes compressible and recoverable. The colloidal composition comprises a vegetable oil reaction product based compound. Experiments with the new composition have demonstrated that it can be successfully used in a much wider range of parameters than before to form a barrier resulting in water displacement, as well as to mobilize and recover residual oil adhering to the well area.
