چکیده:

Nowadays, polymer gels are widely used to prevent unwanted water production from oil reservoirs. In this paper, Cr(III)-acetate/ polyacrylamide copolymer gel behavior was evaluated in the Ahwaz-Asmari oil reservoir conditions considering reservoir temperature and water formation. Afterwards, an experimental study was performed to assess the polymer gel performance to reduce water permeability by coreflood experiments. The results showed that quality of water formation can have significant influence on the gel polymer properties especially presence of divalent cations in formation water decreased gelation time. Also, based on coreflood results average water permeability was about 1 mD for the treated core after gel treatment.
