| Summary: | Oil and gas production from reservoirs is a crucial aspect in meeting global energy demands. However, aging
reservoirs tend to experience production decline due to natural depletion. To mitigate these negative impacts and
maximize the economic benefits from wells, effective reservoir management is essential. One modern approach
used is reservoir zone shifting to enhance well performance.
This study focuses on the KX09-ST Gas well, which has been producing gas from the ZX-2 and ZX-3 zones. Despite
experiencing production decline, a plan is being devised to shift production back to the UGX zone, which
previously yielded successful oil production. The purpose of this study is to determine the best case to get timing
of the zone shifting that results in the highest net gain by performing production forecast based on water cut
sensitivity.
The analysis is carried out through forecasting production profiles for the newly shifted zone well, comparing net
gains across various sensitivity scenarios of water cut and timing. The results of this study obtained three
scenarios for the zone shifting timing based on the water cut, then it was suggested to run a production logging
tool to ensure the water cut in the new targeted zone. |
