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

Well “HE-04” in Field “S” is a hydrocarbon production well located in a reservoir with relatively low permeability, measured at 10.80 mD. This low permeability results in a low productivity index (PI). To enhance well productivity, hydraulic fracturing was performed to create conductivity between the reservoir and the wellbore, with the objective of increasing the PI. Hydraulic fracturing involves injecting fluid at high pressure to create fractures in the formation, followed by the placement of proppant to keep the fractures open. However, post-fracturing results indicated that the dimensionless fracture conductivity (FCD), which represents the fracture conductivity, remained low. Therefore, evaluation and optimization of the fracture geometry are necessary to achieve optimal conductivity and improve PI. This study evaluates the PI using the Prats method and optimizes the fracture geometry by redesigning the initial fracture using the Unified Fracture Design (UFD) method within the Perkins-Kern-Nordgren (PKN) geometry model. The process begins with an evaluation of the actual PI, followed by redesigning the fracture geometry to determine the maximum fracture dimensions. This maximum geometry is then optimized using the UFD method to obtain the most effective geometry. The optimization results show that the maximum fracture volume that can be generated is 685.51 m³, with a resulting FCD value of 8.37. The fold of increase (FOI) reached 8.54, an improvement of 5.43 compared to the actual FOI. This indicates that the optimized PI increased by 8.54 times from its initial value. Thus, the optimized fracture geometry design proves to be effective in enhancing the productivity of well “HE-04”.

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

Peramalan kebutuhan HCl di PT. ABC sangat penting untuk menjaga kelangsungan unit operasional demineralisasi. Penelitian ini menganalisis data historis penggunaan HCl dari bulan April 2023 hingga November 2023, dengan menerapkan metode moving average untuk periode 2, 3, 4, dan 5. Analisis ini bertujuan untuk menentukan metode peramalan yang paling akurat dalam memprediksi kebutuhan HCl untuk bulan Desember 2023. Hasil Analisis menunjukkan bahwa metode moving average 4 periode memberikan nilai rata-rata deviasi absolut (MAD) terkecil sebesar 11.6875 dan rata-rata persentase kesalahan absolut (MAPE) sebesar 6%. Hal ini menunjukkan bahwa metode tersebut mampu memberikan prediksi yang lebih tepat dibandingkan dengan periode lainnya. Meskipun moving average 2 periode dan 4 periode menghasilkan nilai peramalan yang sama, perbedaan nilai MAD dan MAPE menunjukkan bahwa penggunaan periode yang lebih panjang dapat mengurangi penyiaran dalam peramalan. Temuan ini memberikan kontribusi penting bagi PT. ABC dalam mengoptimalkan penyediaan HCl dan meningkatkan efisiensi operasional. Rekomendasi untuk penelitian lebih lanjut meliputi penggunaan data historis yang lebih representatif, serta penyesuaian model peramalan sesuai dengan perubahan kondisi pasar dan faktor eksternal yang mempengaruhi proses produksi.

Abstract

Program "Tegur Jika Saya Tidak Aman (TEMAN)” bertujuan untuk meningkatkan keselamatan kerja dengan mendorong budaya saling menegur di antara pekerja ketika menghadapi potensi bahaya. Penelitian ini mengevaluasi implementasi program TEMAN di suatu perusahaan dan mengidentifikasi kendala-kendala yang dihadapi melalui metode USG (Urgency, Seriousness, Growth). Hasil evaluasi menunjukkan bahwa 87,5% pekerja telah mengimplementasikan program, namun terdapat enam kendala utama yang ditemukan termasuk pimpinan yang belum menjadi teladan, preferensi pekerja untuk tidak menerapkan program, serta sosialisasi yang kurang efektif. Ketidakmauan menerima teguran, rasa sungkan dalam menegur, dan kekhawatiran akan menyinggung rekan kerja juga menjadi masalah yang signifikan. Untuk mendapatkan pemahaman lebih mendalam, tiga kendala prioritas dianalisis menggunakan fishbone diagram yang mengidentifikasi faktor penyebab dari aspek manusia, metode, dan proses. Dalam aspek manusia, kurangnya kesadaran pimpinan dan pekerja menjadi sorotan utama. Dari sisi metode, sosialisasi yang kurang efektif diperhatikan, dan pada aspek proses, pelaksanaan program yang tidak teratur berkontribusi pada masalah ini. Berdasarkan hasil analisis, solusi yang diusulkan mencakup peningkatan sosialisasi kepada pimpinan agar dapat berfungsi sebagai teladan bagi pekerja, pemberian penghargaan kepada pekerja yang aktif menerapkan program, serta peningkatan variasi dan efektivitas dalam metode sosialisasi. Implementasi solusi ini diharapkan dapat meningkatkan keberhasilan program TEMAN dan menjaga budaya keselamatan kerja, serta mempertahankan zero LTI (lost time injury) di lingkungan kerja.

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

Proses pemboran minyak menghadapi risiko kick—masuknya fluida formasi ke kolom bor—yang berpotensi memicu blowout. Sistem Blowout Preventer (BOP) mengandalkan adaptor flange 13- 5/8” berkapasitas 5.000 psi dan 10.000 psi sebagai antarmuka penahan tekanan. Penelitian ini menganalisis desain flange melalui evaluasi ketebalan minimum, area kritis, dan validasi material. Metode analitis berbasis standar American Petroleum Institute (API) menghitung tekanan desain (67.500 psi) dan kekuatan material (84.324 psi), menghasilkan margin keamanan 25%. Simulasi ketebalan minimum flange 13-5/8” menunjukkan ketebalan desain teoritis 0.529” (dipengaruhi tekanan internal dan tegangan izin material), sedangkan ketebalan aktual 0.419” tetap memenuhi safety factor. Analisis area kritis pada flange 5.000 psi mengidentifikasi konsentrasi tegangan di dua lokasi: 2.58” (daerah transisi geometri) dan 1.20” (sekitar bolt hole), yang direkomendasikan untuk dioptimalkan melalui fillet radius. Studi membuktikan desain flange memenuhi integritas struktural untuk kedua level tekanan, dengan ketebalan aktual lebih rendah akibat pendekatan konservatif persamaan Barlow. Hasil ini memvalidasi efisiensi material dan geometri komponen tekanan tinggi, mengurangi risiko kegagalan katastropik selama operasi pemboran. Implikasi praktisnya mencakup penguatan desain berbasis simulasi tegangan dan optimasi lokal pada area rentan, menjamin keandalan sistem BOP dalam skenario tekanan ekstrem.
