Laboratory Evaluation of Crosslinked Polymer Gels for Water Diversion
Many crosslinked gel treatments are currently available for injection profile modification in secondary oil recovery waterflood operations. The gels usually consist of a water-soluble polymer, such as polyacrylamide or polysaccharide, crosslinked with a metal ion (A13+, Cr3+, Zr4+) or organic compounds. Due to the large number of systems available and possible conditions which must be considered, a rapid testing procedure must be used to screen these systems on a timely basis.
