Probing the gelation of polyvinylalcohol-water-glutaraldehyde within a porous material by \+sp\1\-sp\H NMR - a preliminary investigation

To control water mobility and water profiles in injectors for enhanced oil recovery, high viscosity polymer fluids and gels have been used, but it is necessary for the pregel solution to be placed in a fracture or porous zone before gel formation. The gelation process was studied using a porous mode...

Zusammenfassung:	To control water mobility and water profiles in injectors for enhanced oil recovery, high viscosity polymer fluids and gels have been used, but it is necessary for the pregel solution to be placed in a fracture or porous zone before gel formation. The gelation process was studied using a porous model system of packed ballotini. (Abstract quotes from original text)
