Abstract

production from old wells, both Secondary Recovery and Tertiary Recovery. The RS#28 well and NK#13 well in the GK field are wells located in the Central Sumatra Basin and have commercial oil and gas reserves to manage. The RS#28 well is a light oil type well with a high paraffin content and requires Tertiary Recovery stimulation to produce it. One of the efforts made is the stimulation of Electrical Stimulation Oil Recovery (ESOR). This stimulation utilizes Direct Current (DC) flows through production pipelines which can increase oil mobility and increase production. It is hoped that this research can analyze the economics of ESOR stimulation and can be applied to various old wells in Indonesia. Judging from the economic indicators that have been carried out on the RS#28 well and the NK#13 well, the NPV results for the RS#28 well = $ 80,762.58, IRR = 57.9%, POT = 1.78 years and PI = 1.78 and for the NK#13 well NPV value = $ 102,758.9 with IRR = 52.9%, POT = 1.69 years and PI = 1.99. Based on the ESOR economic analysis, it was found that it had been calculated for the spelling of the ESOR method on the RS#28 Well and NK#13 Well. The IRR value obtained is quite high and the Pay out Time is the fastest where the investment capital is returned within 1.78 months for the RS#28 well and 1.69 months for the NK#13 well. Whereas the Profitability Index (PI) value obtained is more than 1 which has a fairly high value, namely 1.78 for the RS#28 well and 1.99 for the NK#13 well and is declared feasible for work on the two wells. Based on the economic indicators, it is stated that the NK#13 well is more economical than the RS#28 well.
