Comparative Study of Biopolymer Flooding: A Core Flooding and Numerical Reservoir Simulator Validation Analysis

Polymers increase the macroscopic efficiency of flooding process and crude oil recovery. The viscosity 3 polymers xanthan, guar, Arabic gums is measured in lab experimented with as EOR options. Xanthan guar gum are weight percentages 0.1, 0.2, 0.4, 0.5, 1, while 5, 10, 15 percentages. experiments showed that had lowest at 15% wt. significantly higher viscosities than corresponding At same 0.5%, recorded a 63%, 53%, 46% recovery, respectively. Due to limitations surrounding core such human error, equipment failure, measurement recoveries, it necessary validate results obtained other methods reservoir simulation. A model built (using Eclipse) incorporated polymer functions from experiments. Peak recovery 9.96%, 9.95%, 9.90% was for gum, respectively, percentage 0.5% weight. Also, increasing wt% injected increases Results also indicate trend recoveries during follows observed simulation production increased all cases considered.
