Evaluating the performance of designed terpolymers for polymer flooding

In this work, polymeric materials designed for enhanced oil recovery (EOR) were evaluated their intended application. Properties including viscosity, flow through porous media (resistance factor and residual resistance factor), heavy displacement (incremental recovery) assessed terpolymers of 2-acrylamido-2-methylpropane sulphonic acid (AMPS), acrylamide (AAm), acrylic (AAc). The same properties two commercially available reference (e.g., partially hydrolyzed polyacrylamides or HPAM) with similar characteristics, which allowed direct comparison between the newly that are currently on market polymer flooding incremental directly associated flooding, includes both post-polymer waterflooding stages (excluding initial injection (or secondary) recovery), demonstrates provided a higher (42% 58%) than (33% 46%). Therefore, contribution to enhanced) typical HPAM. Additionally, showed better injectivity in unconsolidated less likely cause plugging materials. using targeted design approach ultimately led excellent performance EOR applications.
