EVALUASI CASING SETTING DEPTH BERDASARKAN
VALIDASI KICK TOLERANCE MENGGUNAKAN DRILLER’S

Sumur “AB-09” merupakan sumur eksplorasi yang terletak di Cekungan Jawa
Timur Utara yang menghadapi banyak permasalahan selama pengeboran berupa
tingginya frekuensi kick, khususnya saat memasuki zona gas, serta kejadian loss
circulation pada beberapa kedalaman. Permasalahan tersebut menyebabkan
peningkatan waktu pengeboran hingga 122 hari, jauh dari target awal pengeboran
yaitu 64 hari, serta meningkatkan risiko keselamatan operasi. Oleh karena itu,
diperlukan evaluasi terhadap penentuan casing setting depth dan berat lumpur
dengan validasi kick tolerance untuk memastikan ketahanan desain casing serta
efektivitas berat lumpur dalam mengendalikan tekanan formasi.
Penelitian menggunakan pendekatan kuantitatif dengan analisis numerik berbasis
studi kasus, yang dimulai dari pengumpulan data, penentuan casing setting depth
dan berat lumpur serta korelasi dengan data pore pressure-fracture gradient
(PPFG) dan litologi, perhitungan panjang dan volume influx pada mata bor serta
casing shoe, penentuan kick tolerance, serta mengevaluasi casing setting depth dan
berat lumpur.
Hasil penelitian menunjukkan bahwa diperlukan perubahan pada kedalaman casing
9-5/8” menjadi 5512 ftTVD dan berat lumpur pada trayek 12-1/4” menjadi 9,92
ppg serta trayek 8-1/2” menjadi 13,77 ppg. Melalui analisis hasil kick tolerance,
berat lumpur, dan kedalaman casing terdangkal, evaluasi ini menunjukkan
pentingnya validasi kick tolerance pada Sumur “AB-09” dalam perencanaan casing
setting depth untuk meningkatkan keamanan operasi dan efisiensi biaya
pengeboran dengan meminimalkan potensi kick dan tetap memenuhi standar kick
tolerance.
Kata kunci: casing setting depth, Driller’s method, kick, kick tolerance, well control

ABSTRACT
CASING SETTING DEPTH EVALUATION BASED ON KICK
TOLERANCE VALIDATION USING DRILLER’S METHOD ON
WELL “AB-09” “EL” FIELD

Well “AB-09” is an exploration well located in the North East Java Basin, which
encountered numerous challenges during drilling, including a high frequency of
kicks, particularly when entering the gas zone, and several occurrences of loss
circulation at various depths. These issues led to an increase in drilling time to 122
days, far beyond the initial target of 64 days, and also raised safety risks during
operations. Therefore, an evaluation of the casing setting depth and mud weight
with kick tolerance validation is required to ensure the integrity of the casing design
and the effectiveness of the mud weight in controlling formation pressure.
The study employs a quantitative approach with numerical analysis based on a case
study, beginning with data collection, determination of casing setting depth and
mud weight along with correlation to pore pressure–fracture gradient (PPFG) and
lithology data, calculation of influx length and volume at the bit and casing shoe,
determination of kick tolerance, as well as evaluation of casing setting depth and
mud weight.
The results indicate the need to revise the 9-5/8” casing depth to 5512 ftTVD, with
mud weights adjusted to 9.92 ppg for the 12-1/4” section and 13.77 ppg for the 8
1/2” section. Through the analysis of kick tolerance, mud weight, and shallowest
casing depth, this evaluation highlights the importance of kick tolerance validation
in casing setting depth planning for Well “AB-09” to enhance operational safety
and drilling cost efficiency by minimizing kick potential while still meeting kick
tolerance standards.
