Abstract

: There are still have a potential oil to be produced, the reduced reservoir pressure due to continuous oil production at
a high rate, and the high water cut value are the background for the polymer injection process in the BKH Layer of YDP Oil Field.
Due to a high water cut value, the study then conducted using a polymer injection method. Screening criteria for polymers
injection was conducted to see the suitability of the reservoir, and then carry out an advanced scenarios using polymers of various
concentrations to be compared, and see a cumulative incremental oil production and recovery factor. The stages including
collecting and preparing data, processing and analyzing RCAL, SCAL, and PVT data, input data to simulation model with actual
conditions. The reservoir simulation performed including initialization, history matching and PI matching, carry out polymer
injection scenarios with certain polymer concentrations, then predict and analyze the scenario results, and finally determine the
best polymer injection scenario to be applied in the BKH layer of YDP field. Based on the results of the study, it is shows that the
scenario IV-A is the best scenario for polymer injection compared to other scenarios. Scenario IV-A performed by injection of
polymer with a peripheral pattern with an additional 5 (five) injection wells, injection pressure of 1200 psi, injection rate of 300
bbl/d, polymer concentration of 0.6 lb/bbl, incremental recovery factor of 2.01%, and oil production cumulative obtained until
December 2035 is 5087 MSTB.
