Abstract:In this review article, a novel kind of chemical flooding systems, colloidal dispersion gels (CDGs), is introduced. The advantages and differences of CDG treatments from polymer flood and polymer gel profile modification are pointed out. The composition (various kinds of crosslinkers for polyacrylamides), structure and methods of evaluation of CDGs are discribed in comparison with that of common, bulk polymer gels. The results of 29 pilot tests published in literature are presented briefly.
Keywords:Colloidal Dispersion Gel  Indepth Drive Fluid Diversion  Crosslinked Polymers  Crosslinkers  Polyacrylamides  Enhanced Oil Revovery  Review
