Analisa Perancanaan Lumpur Pemboran Menggunakan HPEBM pada Sumur "E" Lapangan "P"

The “E” well to be drilled is a development in the “P” field located North Sumatra Basin. During drilling operation using HPWBM, HPWBM used overcome shale instability. This water-based mud because it cheaper and more economical than oil-based mud. However, this needs added with other chemicals has weakness controlling formation. system design for uses offset method, which data from nearby wells comparison. Well divided into two intervals. Hole interval 12 1/4" 9 5/8" casing 24 m 290 depth HPWBM. Then proceed 8 1/2" hole intervals 7" 530 same problem will face pressure at of 500 m, thus increasing density ppg 14 prevent kick.
