Abstract

The "CN" field is a long term closed (LTC) oil and gas field where the well production does not always run well, causing problems such as increasing produced water. The well will be reopened if the value of the well is considered economical (well reactivation). Therefore, it is estimated that the field still has remaining oil reserves. In this study, the candidate wells for reactivation were determined using the Decline curve analysis (DCA) method. Prior to reactivation, this study looks at the economic value of the well, this study uses economic calculations with the revenue cost Ratio (R/C Ratio). From the decline curve analysis forecasting, the wells that are candidates for reactivation are all candidate wells in the CN field. The well with the most profitable remaining reserves in the future is the CN6 well with a value of EUR 1578 MSTB. From an economic aspect, the CN6 well is feasible to run with a value of R/C = 19, which if the R/C value> 1 then the business or activity is feasible.
