Paper Number: SPE-165191-MS
... system is discussed that provides high differential pressure for the fluid flow by forming a low-permeability filter cake on the formation face or bridging the perforation tunnel, or by plugging pore throats, which helps divert fluid to other zones. The system consists of degradable polymer particulates...

... experimentally evaluate breaker requirements to achieve a target uncrosslinked filtercake viscosity. Experiments were conducted to determine kinetics of polymer degradation by simple hydrolysis at temperature and degradation by sodium chlorite and sodium persulfate breakers. Temperatures ranged from 85 to 280°F...

... concentration (1–2% v/v) and an iron complex activator. By coreflooding tests the effectiveness of this breaker to remove the external filtercake and the polymers, which entered the formation, was identified. Experimental results showed that this type of oxidants can degrade the polymers contained in the...
