The study aims to establish both quantitative and qualitative correlations between these parameters to predict the water cut that may occur following remedial cementing operations. Through comprehensive data analysis and plotting, the study identifies significant correlations, offering valuable insights for improving predictive accuracy and decision-making in cementing processes. The findings provide a result for better understanding the impact of Chan’s plot parameters on the Bond Index, thereby enhancing the efficiency of cementing process in similar field operations. Keywords: Chan’s Plot, Bond Index, Correlation Sari Studi ini menyajikan analisis hubungan antara parameter Pemodelan Chan, khususnya Rasio Air Minyak dan Derivatif Rasio Air Minyak (WOR'), dan indeks keterikatan semen dalam proses penyemenan di Lapangan X. Studi ini bertujuan untuk menetapkan korelasi kuantitatif dan kualitatif antara parameter-parameter tersebut untuk memprediksi produksi air yang mungkin terjadi setelah operasi penyemenan perbaikan. Melalui analisis data yang komprehensif dan plotting, studi ini mengidentifikasi korelasi yang signifikan, memberikan wawasan yang berharga untuk meningkatkan akurasi prediksi dan pengambilan keputusan dalam proses penyemenan. Temuan ini memberikan hasil untuk lebih memahami dampak dari parameter Pemodelan Chan terhadap indeks keterikatan semen, sehingga meningkatkan efisiensi proses penyemenan pada operasi lapangan yang serupa. Kata Kunci: Plot Chan, Indeks Keterikatan Semen, Korelasi 1 Student of Petroleum Engineering Study Program, Institut Teknologi Bandung, Class of 2024 2 Thesis Adviser in Petroleum Engineering Study Program, Institut Teknologi Bandung.
