Study on The Rheological Properties of Partially Hydrolysed Polyacrylamide Solution at Elevated Temperatnre

The main purpose of using polymer in enhanced oil recovery is to increase the viscosity of
water. In this aspect, maintaining the viscosity of aqueous polymer solution in harsh
environment conditions like high temperature and high pressure is a challenge. Thus, it is
important to investigate the rheological behaviour of the polymer under such condition. In this
study, partially hydrolysed polyacrylamide (PHPAM) solution was chose as the case study.
PHPAM solution was experimented under elevated temperature range from so·c to 100 ·cat
atmospheric pressure. PHP AM solution in the range of 500 ppm for master solution and I 0
ppm 50 ppm for diluted solution were covered. Brookfield cap 2000+ viscometer is employed
for operating, measuring and analysing this experimental investigation. The results obtained
are expected to provide better understanding on the flow behaviour of HP AM at elevated
temperature.
