Studi ini mengevaluasi efektivitas metode hesitate cementing untuk memitigasi risiko formation breakdown pada Sumur BIL07 yang memiliki pressure window kritis (tekanan reservoir 1650 psi vs fracture pressure 2200 psi). Menggunakan model numerik berbasis Python yang mengintegrasikan reologi Bingham Plastic dan persamaan leak-off Carter, lima skenario injeksi disimulasikan dan divalidasi terhadap profil tekanan injeksi dinamis aktual (RMSE 28,5 psi). Hasil simulasi menunjukkan bahwa Skenario C (Hesitate Low Rate: 5 menit ON / 3 menit OFF) berhasil mengubah status operasi dari High Risk menjadi Safe/Optimal, dengan menurunkan tekanan injeksi maksimum dari 2133 psi menjadi 1857 psi. Strategi ini memperluas safety margin secara drastis dari 67 psi menjadi 343 psi (naik 512%) dan meningkatkan efisiensi penempatan slurry dari 75% menjadi 88%. Meskipun durasi operasi bertambah 3,9 menit, studi ini menyimpulkan bahwa mekanisme disipasi tekanan transien selama fase diam (OFF) sangat krusial untuk menjamin integritas sumur tanpa mengorbankan kualitas penyemenan.
