Abstract

The implementation of polymer injection on a field scale needs a preliminary laboratory test to analyze the
performance and flow behavior of polymer injection in a porous media. Compared to core flooding method,
micromodel provides the visualization of oil displacement mechanism and facilitating a more detailed
process description. Understanding the effect of polymer concentration on the incremental of oil recovery
factor and its displacement mechanism are essential to know the polymer injection performance with the
intention of avoiding failures in the implementation of polymer injection at field scale. We used dry etching
technique for the fabrication of acrylic micromodel with homogenous characteristic. In this work, pre-flush
(waterflooding) is performed first before doing the polymer injection to determine the incremental oil
recovery factor and analyze the effect of polymer concentration on oil recovery factor enhancement in
homogenous porous media. They were positioned horizontally then saturated with synthetic brine and light
crude oil as the initial condition before starting the injection scenario. The experiment was conducted at
room temperature. The entire process of micromodel flooding test was monitored by camera and then for
the further analysis was done using Digital Image Analysis (DIA). According to the polymer rheology and
aqueous stability test, it can be proven that polymer is a non-newtonian fluid indicated by shear thinning
behavior and it can be observed that FP3630S polymer is a good candidate for micromodel flooding test. The
micromodel flooding result confirmed that the increasing of polymer concentration will result in higher
incremental oil recovery factor. In addition, based on the final condition of the micromodel after the polymer
injection process, there is improvement of sweep efficiency due to the front stability resulted by the
decreasing of mobility ratio between displacing fluid (polymer solution) and the oil bank.
