PERANCANGAN DESAIN CASING PADA SUMUR IBZ-33 BERDASARKAN ANALISIS BURST, COLLAPSE, DAN AXIAL LOAD Iman, Ibnu Casing is a primary component in well construction that functions to maintain wellbore stability, isolate formations, and ensure integrity and operational safety during drilling and production activities. Proper casing design is essential to prevent mechanical failure caused by pressure and axial loads acting throughout the well’s lifecycle. This study aims to design the casing configuration for Well IBZ-33 based on the analysis of major mechanical loads, namely burst, collapse, and axial loads, while considering pore pressure and fracture gradient as the basis for determining operational pressure limits. The design process was carried out by evaluating each casing interval through differential pressure and axial load calculations, which were then compared to pipe ratings in accordance with API (American Petroleum Institute) standards. The design parameters determined include casing size, weight (ppf), and material grade to ensure that all operating loads remain within safe limits. The results indicate that the proposed casing design is capable of withstanding burst, collapse, and axial loads within acceptable safety margins, thereby maintaining the integrity of Well IBZ-33 and serving as a reference for casing design in wells with similar geological and pressure characteristics.

Analisis Kinerja Produksi dengan Penerapan Liquid Constraint Menggunakan Metode Pemodelan Lapangan Terintegrasi (IPM) Alvin, Muhammad Lapangan minyak yang telah memasuki fase produksi lanjut umumnya menghadapi penurunan tekanan reservoir, peningkatan produksi air, serta keterbatasan kapasitas fasilitas permukaan. Kondisi tersebut menyebabkan potensi produksi reservoir tidak selalu dapat direalisasikan secara optimal, sehingga diperlukan pendekatan analisis yang mampu menggambarkan interaksi antara reservoir, sumur, dan fasilitas permukaan secara terintegrasi. Integrated Production Modeling (IPM) merupakan metode yang dapat digunakan untuk mengevaluasi kinerja sistem produksi lapangan secara menyeluruh dan realistis. Penelitian ini bertujuan untuk menganalisis kinerja produksi Lapangan X pada skenario pengembangan dengan penerapan liquid constraint menggunakan pendekatan IPM. Pemodelan reservoir dilakukan menggunakan MBAL untuk mengevaluasi karakteristik reservoir dan perilaku tekanan, sedangkan pemodelan sumur dilakukan menggunakan PROSPER untuk menganalisis performa aliran sumur. Selanjutnya, seluruh model diintegrasikan ke dalam GAP untuk membangun model lapangan terintegrasi dan menyimulasikan kondisi produksi tanpa batasan serta kondisi dengan liquid constraint akibat keterbatasan kapasitas separator selama enam bulan awal produksi. Hasil simulasi menunjukkan bahwa penerapan liquid constraint menyebabkan perlunya pengaturan choke pada masing-masing sumur dan penutupan sementara pada sumur tertentu guna menjaga laju fluida total tetap berada dalam batas kapasitas fasilitas. Kondisi ini berdampak pada penurunan produksi minyak kumulatif dibandingkan dengan skenario tanpa batasan. Selain itu, hasil perhitungan recovery factor pada masing-masing reservoir menunjukkan adanya penurunan nilai akibat keterbatasan fasilitas. Hasil penelitian ini menunjukkan bahwa pendekatan IPM efektif dalam mengevaluasi kinerja produksi lapangan dan mendukung pengambilan keputusan teknis pada kondisi keterbatasan fasilitas.

OPTIMALISASI PRODUKSI MINYAK DENGAN STRATEGI REAKTIVASI SUMUR PRODUKSI DAN INJEKSI AIR PADA LAPANGAN Z Andreansyah, Muhammad This study evaluates the remaining production potential of the mature Z Field through an integrated approach using Material Balance (MBAL), Decline Curve Analysis (DCA), and injector performance evaluation. The MBAL analysis indicates that the Z Field contains an Original Oil in Place (OOIP) of 52.85 MMSTB and is characterized by a combined drive mechanism, with solution gas drive dominating the early production stage and supported by water injection drive during the later stage. Production forecasting using an economic limit of 25 BOPD yields an Estimated Ultimate Recovery (EUR) of 12.17 MMSTB for the six-well reactivation scenario, which increases to 15.90 MMSTB with the addition of three production wells, resulting in an improvement of recovery factor from 24.05% to 30.09%. Exponential DCA applied to six reactivated wells estimates an aggregate EUR of 2.72 MMSTB, corresponding to a recovery factor of approximately 5.14% of the field OOIP, and identifies wells ZELE-01, ZELA-06, and ZELA-02 as the highest-priority candidates based on remaining recoverable volumes. Injector performance analysis using Voidage Replacement Ratio, Chan Plot, and Hall Plot demonstrates that water injection contributes to reservoir pressure maintenance, although its effectiveness varies spatially and temporally, thereby supporting the combined drive interpretation and providing a realistic assessment of the opportunities and limitations of well reactivation in the Z Field.
