Abstract

The study aims to identify solutions to declining oil production and frequent failures of the electrical submersible pump (ESP) and its cable in D-04 well caused by CO2 gas channelling, as well as to evaluate the effectiveness of remedial cementing in addressing these issues. An integrated analysis was conducted through the implementation of Cement Bond Log (CBL) and Variable Density Log (VDL) to identify the problematic zones. The results were used to determine the necessity of re-cementing and zone-specific reformulation. In addition, well performance evaluation after cement bond improvement was evaluated by comparing production performance before and after remedial cementing. The analysis identified three zones requiring remedial cementing, located at intervals of 1040-1041 mMD, 1045-1048 mMD, and 1055-1057 mMD. The remedial cementing process was carried out in three stages: the first stage to seal the productive zone, the second stage to improve bonding in the CO2 gas channelling zone, and the third stage to improve bonding in the water channelling zone. Based on CBL and VDL logs as well as well performance before and after remedial cementing, the results indicate that the overall bonding improvement in cement bonding successfully isolated gas and water zones, and had a positive impact on production performance, as evidenced by an increase in oil production cumulative from 1370 bbl to 1452 bbl.
