Abstract

The results of preliminary polymer flood laboratory study, including the matched coreflood simulation model results were shown to decide about analytical procedure for more detailed polymer flood study. The coreflood model is confirmed as feasible by comparing the recovery after waterflood period and after the polymer flood period. Sensitivity analysis of fluid compressibilities, parameters that affect polymer solution rheology, relative permeability and polymer adsorption index was perfumed both in laboratory and by simulation model. The results shown how different parameters affect recovery and additional recovery from polymer flood versus time. This method helped to speed up the assessment of critical parameters which should be measured and analyzed in more detailed study.
