Abstract

Polymer injection is one method of chemical enhanced oil recovery,
which increase oil recovery by improving mobility when viscous
fingering occurred in waterflooding operation. The result of polymer
injection is better sweep efficiency, which is presented by more even
distribution of the injected fluid. However, in common laboratory
evaluation for polymer injection testing, it was no visual observation
that presents directly for the fluid distribution. This experimental
study was carried out to visually observe the polymer injection
mechanism to displace oil by micromodel as porous media. The
micromodel used in this study is transparent acrylic material which
was etched by laser engraving technology to create grains that
resemble reservoir rocks. The micromodel was saturated by brine
water and light oil respectively as initial reservoir fluids. Then, the
water was injected as waterflooding operation to displace oil in a
micromodel. Hydrolyzed Polyacrylamide (HPAM) polymer with
various concentrations were injected into the micromodel as the last
scenario. Through this experiment,the movement and distribution of
fluids in chemical enhanced oil recovery especially polymer injection
was able to be recorded for further analysis. Observation for each
scenario was done by Digital Image Analysis (DIA). The micromodel
flooding results showed that the higher concentration of polymer
would give higher oil recovery. The front stability and good
distribution of polymer will result in better sweep efficiency, then
higher oil recovery will be achieved. This experiment gives result
visually how polymer enhance oil recovery. This experiment is
expected to be leading innovation for Enhanced Oil Recovery (EOR)
laboratory studies inIndonesia
