Abstract

Most of the shut-in wells in the DAL structure have a high water cut
value. Strategy for reactivation of shut-in wells in the DAL structure
begins with the screening of wells and layers with well parameters such as
high water cut (WC) more than 90%, comparison of recovery factor from
cumulative production with in-place wells radius and calculation of
recovery factor based on special core analysis (SCAL) data, production
forecast, and economic analysis. Based on the screening results, the DAL-
031 well was selected as a candidate for the reactivation well, which was
closed on January 21, 2016 due to high water cut. The strategy for
reactivation of the DAL-031 well by perforating at interval 1884-1887 m
and obtained oil gain of 47.04 bopd with correlation well analysis and
forecast with exponential decline type for 8 years. Economic analysis was
carried out by analyzed economic indicators 315.42 MUSD of net present
value (NPV), 77% of internal rate of return (IRR), and 11 months and 28
days of pay out time (POT). Based on the technically and economic
analysis, it was concluded that reactivation strategy of DAL-031 shut-in
well is feasible to be applied.
