Sensitivity Study of The Effect Polymer Flooding Parameters to Improve Oil Recovery Using X-Gradient Boosting Algorithm

Implementation of waterflooding sometimes cannot increase oil recovery effectively and requires additional methods to recovery. Polymer flooding is a common chemical EOR method that has been implemented in the last few decades provides good effectiveness increasing can reduce amount injection fluid injected into reservoir. Seeing success polymer recovery, it necessary know parameters influence so be evaluated taken consideration creating new scheme with flooding. The tested this study include Injection Rate, Time, Pressure, Adsorption, Inaccessible Pore Volume, Residual Resistance Factor. This research uses X-Gardient Boosting Algorithm look at most influential performance on value importance level each parameter are time 0.452632, rate 0.430075, pressure 0.064662, Adsorption 0.025564, RRF 0.021053, IPV 0.006014 produce accurate predictive modeling using x-gradient boosting where 3 variations comparison ratio training testing data obtained 0.7 : 0.3 an R2 train 0.9886 test 0.9645, 0.8 0.2 0.9891 0.9579, 0.9: 0.1 0.9890 0.9660.
