Abstract

This study focuses on analyzing sand grain size distribution from Well A-140 using sieve analysis to determine the optimal gravel pack size for sand control. A series of sieves with varying mesh sizes were used to separate the sand particles, and the cumulative weight of each fraction was converted into a percentage based on the total sample weight of 54.437 grams. The results revealed a relatively uniform grain size distribution, indicated by a sorting coefficient of 2.0625, classified as "well-sorted" according to standard sedimentological criteria. The median grain diameter (D50) obtained from the grain size distribution curve was approximately 0.0098 inches. Based on this value, the recommended gravel pack size is 40/60 mesh, with a screen gauge size of 0.008 inches. These findings provide practical insights for designing an effective gravel pack to reduce sand production, enhance well integrity, and maintain stable oil and gas production performance.

Abstract

This study evaluates the feasibility of using a specific cement composition for the abandonment of a non-productive perforated zone at a depth interval of 2631–2640 ft in well MAW-11, located in the Mata Allo Field. Laboratory tests indicate that the cement formulation meets the required performance standards, with a thickening time of 5 hours and 8 minutes at 116 °F and a compressive strength of 2430 psi after 24 hours at 137 °F. Engineering calculations were conducted to determine slurry volume requirements and injection parameters under two scenarios: tight rate injectivity and high rate injectivity. The results show that both scenarios fall within acceptable operational limits. The estimated total cost for the cementing operation is IDR 166,622,550 under tight-rate conditions and IDR 171,493,750 under high-rate conditions. These findings confirm that the cementing plan is both technically feasible and economically viable.

Abstract

Oil wells with water drive propulsion, if produced then water will move towards the well hole to form a cone. Under certain conditions, water will break into the well and begin to be produced along with oil and this phenomenon is called water coning, therefore a critical flow rate calculation is carried out to determine the limit of the flow rate allowed by the well to produce without water coning. The purpose of this final project research is to determine the value of the critical flow rate in the methods used, namely the Mayer Gardner and Pirson method and also the Schols method, and the calculation of time to brekthrought with the Sobicinski and Cornelius method is carried out to determine the time needed for water to reach bottom perforation. The results of calculating the flow rate with the Mayer Gardner and Pirson method of 5.21 STB / day, then obtained time to breakthrough for 82437,02 days, and at the flow rate with the schools method of 0.23 STB / day obtained a flow rate of 4729678 days and if the well is produced at the actual rate of 86.5684 STB / day then the time to breakthrough is obtained for 418 days.

Abstract

Horizontal wells are wells that are widely used in the oil and gas industry considering their effectiveness in increasing the productivity of a well. In field V, horizontal wells are not completely horizontal (90 degrees). Due to deviations in the geological formation, the drilled wells follow the formation dip. This study aims to determine the most optimal well model from several scenarios (toe-up, horizontal, or toe-down) and identify the dominant flow regime in the well. In this study, the author models well productivity and flow regimes with several scenarios. Such as the original scenario, true horizontal (90 degrees), toe-up (95 and 100 degrees) and toe-down (80 and 85 degrees). In each scenario, several different flow patterns or flow regimes can occur such as dispersed bubble flow, plug flow, annular flow, and slug flow. After comparing the productivity of each scenario, the results show that the toe-up scenario (100 degrees) has the highest oil production rate of 9401.8 STB/day, the original scenario 8599.7 STB/day, and the toe-down scenario (80 degrees) with 8237.6 STB/day has the lowest oil production rate. Therefore, toe-up (100 degrees) is the optimal well model used for horizontal wells in the V field compared to other scenarios. The gradient matching results for all well scenarios show a bubble flow pattern along the horizontal section of the well.

Abstract

In oil and gas production, horizontal wells are increasingly used to enhance reservoir performance by placing a longer wellbore section within the reservoir. These wells often adopt specific inclinations either upward-sloping or downward-sloping terminal sections to align with formation dip and minimize issues such as liquid loading. However, undulating trajectories in horizontal wells may lead to challenges such as liquid accumulation in downward-sloping sections and gas entrapment in upward-sloping sections, potentially reducing production efficiency. This study aims to predict fluid production rates and analyze multiphase flow behavior in horizontal wells with varying wellbore inclinations using a production simulator. Four scenarios were modeled: Original, True Horizontal, Upward-Inclined End (95° and 100° inclination), and Downward-Inclined End (80° and 85° inclination). The study utilized 20 deviation survey data points from Well F-14 in Field ‘V’ to construct the well trajectory models, adhering to the simulator’s input limitations. Simulation results indicate that the upward-inclined configuration with a 100° inclination achieved the highest oil production rate (9401.8 STB/day), outperforming other scenarios in both oil and gas flow rates. The enhanced performance is attributed to gravitational assistance in fluid movement and reservoir pressure expansion. In contrast, the downward-inclined geometry yielded the lowest production due to higher liquid holdup. Gradient matching was employed to identify dominant flow patterns and slip velocities, revealing bubble flow dominance in horizontal sections and transition to slug flow in mid-well segments. These findings highlight the importance of well trajectory design in optimizing multiphase fluid flow and maximizing production in horizontal wells.

Abstract

Mengestimasikan cadangan minyak dan gas termasuk dalam kegiatan yang utama dalam merencanakan pengembangan lapangan migas. Data yang tersedia atau parameter adalah hal penting untuk memperkirakan besarnya cadangan. Pada kegiatan eksplorasi, informasi data yang ada bisa dibilang sangat sedikit atau terbatas menyebabkan keakuratan dari data yang didapatkan umumnya tidak pasti. Pendekatan secara probabilistik dapat membantu mengurangi faktor ketidakpastian. Simulasi Monte Carlo menggunakan metode dimana perhitungannya dilakukan berdasarkan ketersediaan data lapangan yang masih belum lengkap pada variabel input dan dinyatakan dengan distribusi probabilitas, agar mendapatkan hasil yang tepat dalam bentuk distribusi probabilitas. Perhitungan cadangan hidrokarbon pada lapangan “AT” menggunakan dua distribusi probabilitas yaitu distribusi konstan dan distribusi segitiga. Dengan menggunakan metode Monte Carlo, perkiraan .cadangan minyak di lapangan “AT” menghasilkan rata-rata sebesar 55,95 MMSTB dan gas 27976 MMSCF. Besarnya Most Probable pada minyak didapatkan dengan nilai 42,75 MMSTB dan Gas 21394 MMSCF, Cadangan minimum minyak yaitu 7,131 MMSTB dan gas 3565,67 MMSCF, nilai cadangan maximum minyak yaitu 135,50 MMSTB dan gas 67747,81 MMSCF.

Abstract

Sumur 1 lapangan Osprey merupakan sumur minyak dengan kondisi water cut yang mencapai lebih dari 60% yang menyebabkan pengukuran fluida menggunakan flow meter tidak akurat, sehingga untuk mengukur laju alir fluida dikembangkan machine learning model untuk memprediksi laju alir fluida pada sumur ini dengan menggunkana data set sebanyak 285 set untuk model development dan 280 set untuk model validasi. GOR berkisar antara 300 hingga 900 scf/stb, dan WC hingga 68%. Parameter yang digunakan adalah gas oil ratio (GOR), water cut (WC), flowing wellhead pressure (PU), choke size, downstream pressure (PD), dan oil flow rate (Qoil). Data diklasifikasikan menjadi critical flow dimana kumpulan data dengan kondisi aliran dengan rasio downstream pressure dan upstream pressure kurang dari 0.5. Dari hasi pengembangan dan validasi, model random forest regressor adalah model machine larning yang paling akurat dalam memprediksi laju alir pada kondisi high water cut dan critical flow reservoir dengan nilai MSE = 3.1, MAE = 1.26, RMSE = 1.76 dan R2 = 0.99 dan comparison model random forest regressor dengan empirical correlation Gillbert membuktikan bahwa model machine learning dapat lebih baik memprediksi laju alir jika dibandingkan dengan metrics empirical correlation Gillbert dengan nilai MSE = 59.31, MAE = 6.18, RMSE = 7.70 dan R2 = 0.83.

Abstract

This study will analyze the efficiency of conventional methods and Unbalanced Drilling (UBD) in addressing lost circulation in Kujung Block Z formation. Lost circulation is one of the major challenges in drilling operations that can lead to operational risks and increased costs. This study compares the effectiveness of the two methods based on operational parameters such as rate of penetration (ROP), drill bit load (WOB) and formation pressure stability. The results of this study show that the UBD method is more effective in suppressing lost circulation compared to conventional methods, especially under extremely low formation pressure conditions.

Abstract

Umumnya sumur minyak berproduksi melalui tubing, namun pada kondisi tertentu fluida juga dapat mengalir melalui annulus yang dikenal sebagai flumping, terutama pada sumur dengan Gas Liquid Ratio (GLR) yang tinggi. Kondisi ini terjadi pada sumur SBR-30 yang berproduksi menggunakan Hydraulic Pumping Unit (HPU) dan flumping. Pada bulan Oktober 2022, sumur tersebut mengalami permasalahan ketika flumping berhenti sehingga produksi menjadi bersifat intermittent. Hal ini disebabkan oleh tingginya laju alir gas yang memicu terjadinya gas lock serta menurunnya submergence pompa. Penelitian ini bertujuan untuk mengevaluasi perubahan performa produksi sumur pada kondisi flumping dan setelah flumping stop melalui analisis laju alir maksimum dan Productivity Index (PI), serta menilai kesesuaian kapasitas pompa terhadap kondisi sumur. Metode yang digunakan meliputi perhitungan Inflow Performance Relationship (IPR) menggunakan metode Vogel untuk kondisi aliran dua fasa, perhitungan PI, serta evaluasi Pump Displacement (PD) berdasarkan data produksi. Hasil penelitian menunjukkan bahwa laju alir maksimum pada kondisi flumping sebesar 163,43 Bfpd dengan nilai PI 0,58 Bfpd/psi yang termasuk kategori sedang. Setelah flumping berhenti, laju alir maksimum menurun menjadi 112,62 Bfpd dengan nilai PI 0,32 Bfpd/psi yang termasuk kategori rendah. Selain itu, kapasitas pompa hasil perhitungan sebesar 107,21 bbl/day mendekati nilai laju alir maksimum setelah flumping stop, dengan efisiensi volumetrik sebesar 56%. Kondisi ini menunjukkan bahwa kapasitas pompa sudah mulai tidak optimum, sehingga diperlukan desain ulang pompa agar kinerja produksi sumur dapat lebih optimal dan efisien.

Abstract

Oil and gas energy in Indonesia plays a vital role in driving the country's economy, particularly as a foreign exchange earner and domestic energy supplier. The hoisting system is located on the surface of the rig and works in conjunction with other drilling systems. This study aims to provide an introduction and understanding of the equipment used in hoisting systems in oil and gas drilling activities, enabling students to understand the types of equipment and their uses. This relates to the drilling equipment course, which aims to provide students with a better understanding of the context of practical learning, which is difficult to conduct in the field for direct observation. Therefore, the research method used is a literature review with a qualitative approach to narrate and describe the process of activities carried out in practical learning, starting from the equipment introduction stage, gathering technical information from literature studies, and observing the drilling equipment using sketches and instructional videos of the equipment used in the drilling hoisting system. Based on these observations, students are able to explain and understand the scope of the hoisting system in oil and gas drilling.
