(34) OIL EFFECTS ON THE DEHYDRATION OF SUPER ABSORBENT POLYMERS

This research was conducted to solve problems of Super Absorbent Polymers (SAPs) dehydration in oil field applications.  Two polymer sizes were used separately and mixed with various brines.  After allowing the polymers to fully swell, oil was added to the mixture and the effects of Brine was observed.  Initial readings of oil effects on swelling was taken.  The samples were allowed to hear to 100 degrees Celsius and the effects were recorded. Oil increases the hydration of SAP's for both types of polymers.  Also, for both sizes of polymers, high temperatures caused polymers to float.  The heat lessened density of the polymers.  Particle size was a factor in the behavior of the polymers.  These results can identify which particle size to use according to the brine concentrations, temperatures, and the reservoir fluid properties.  Knowing how oil effects the SAP's helps oil companies to create a formula for each circumstance.
