Abstract

Abstract. The EIO field is an oil field where is categorized as low priority and mature. Based on 2018 reserve report, EIO
field has produced 48% of its original oil in place, with a remaining reserve of 2.074 MSTB. Based on remaining reserve,
there is still potency to optimize the ultimate recovery of this field. ESOR is a new kind of enhanced oil recovery method
which uses electricity directed to reservoir using existing two wells each as an anode and a cathode. The implementations
of ESOR, there are three ways of how this method can improve oil recovery from reservoir, they are electrokinesis effect,
Joule heating, and cold cracking. Based on production decline curve analysis on observation well after ESOR
implementation, it is known that all observation well experience decrease on monthly decline rate (De). Monthly De of E�20 well decreases from 14% to 7.73% which results on additional recovery of 7.1 Mbbl. E-21 well from 39.82 % to
6.47% with additional recovery of 2.22 Mbbl. E-22 from 3.36% to 1.80% with additional recovery of 32 Mbbl. The
analysis of the proximity of wells to changes in the decline rate and changes in API found that the farther the observation
wells are from electrically charged wells, the smaller the changes in the decline rate of wells that occur. Likewise with
changes in API gravity which is directly proportional to the ability of the electric field charge formed of the electric
current from the anode well to the cathode well, the farther the location of the well from the electric field, the smaller the
change in API gravity that occurs.
