Abstract

Penelitian ini berfokus pada pengelolaan persediaan material filter 5M di PT. XYZ yang mengalami penumpukan di gudang akibat pengadaan yang tidak terencana dengan baik. Tujuan penelitian adalah untuk meramalkan kebutuhan material menggunakan metode moving average guna mengoptimalkan pengadaan dan mengurangi kelebihan stok. Data historis pemakaian filter 5M dari tahun 2016 hingga 2023 dianalisis dengan dua periode pergerakan, yaitu 3 tahun dan 2 tahun. Hasil analisis menunjukkan bahwa pergerakan 2 tahun lebih akurat dengan nilai MAD sebesar 292, MSE 113426, dan MAPE 37%. Berdasarkan peramalan tersebut, kebutuhan filter 5M pada tahun 2024 diperkirakan sebanyak 1.095 unit. Pengujian tingkat error menunjukkan bahwa metode pergerakan 2 tahun lebih optimal dibandingkan pergerakan 3 tahun. Untuk meningkatkan akurasi di masa depan, disarankan perusahaan mengkombinasikan metode peramalan lain dan memperpanjang periode analisis. Dengan penerapan metode forecasting yang tepat, perusahaan dapat menghindari penumpukan material di gudang dan meningkatkan efisiensi pengelolaan persediaan.

Abstract

Faktor emisi metana (CH₄) dari pabrik kelapa sawit (POM) di Indonesia merupakan salah satu penyebab utama peningkatan gas rumah kaca yang berkontribusi terhadap perubahan iklim. Untuk mengatasi permasalahan ini, penelitian ini menerapkan machine learning berbasis data satelit guna mendeteksi dan menganalisis pola emisi metana secara otomatis dan efisien. Data yang digunakan diperoleh dari GHGSat, Sentinel-5P TROPOMI, PRISMA, EnMAP, dan EMIT, yang menyediakan informasi spasial dan temporal mengenai distribusi metana di atmosfer. Data ini diproses menggunakan Google Colab, dengan tahapan pembersihan, normalisasi, transformasi variabel, dan seleksi fitur sebelum dilatih menggunakan beberapa model machine learning, yaitu Logistic Regression, XGBoost, Gradient Boosting, Decision Tree, dan K-Nearest Neighbors (KNN). Hasil evaluasi menunjukkan bahwa XGBoost memiliki performa terbaik, dengan akurasi 73.53% dan F1-score 52.28% untuk wilayah dengan emisi tinggi, diikuti oleh Decision Tree dengan akurasi 73.44% dan recall 54.90%. Model lainnya, seperti Logistic Regression dan KNN, menunjukkan hasil kurang optimal dengan recall rendah, yang menyebabkan banyak sumber emisi tidak terdeteksi. Dengan metode ini, deteksi emisi metana dapat dilakukan lebih cepat, akurat, dan dalam skala luas, sehingga mendukung strategi mitigasi perubahan iklim serta keberlanjutan industri kelapa sawit di Indonesia.

Abstract

Sumur WY-31 merupakan sumur hidrokarbon baru yang telah berproduksi selama 97 jam. Oleh karena itu, perlu dilakukan uji sumur pada sumur WY-31 untuk mengetahui karakteristik dan kemampuan produksinya. Pada penelitian ini, dilakukan uji sumur menggunakan pressure build-up (PBU) test dengan metode analisis Pressure Derivative. Tahap pertama melibatkan PBU Test dengan produksi selama beberapa waktu, kemudian sumur ditutup. Hal ini bertujuan untuk mengamati respons tekanan dasar sumur terhadap gangguan. Data yang diperoleh berupa tekanan dan laju alir dasar sumur dianalisis untuk menentukan karakteristik dan parameter produktivitas reservoir, seperti permeabilitas, skin factor, flow efficiency, radius investigasi, boundary reservoir, dan productivity index (PI). Hasil analisis menunjukkan nilai tekanan ekstrapolasi (P*) sebesar 891 psia, permeabilitas 718 mD, skin -1.87, ΔPskin -25 psia, radius investigasi 389.76 ft², productivity index ideal 3.59 bbl/d.psi, productivity index aktual 5.4 bbl/d.psi, flow efficiency 1.4, serta laju alir maksimal 353.27 BOPD yang dihitung menggunakan persamaan Standing. Berdasarkan fitting pada kurva Pressure Derivative, reservoir sumur WY-31 bersifat homogen dengan boundary model parallel fault. Nilai skin negatif mengindikasikan perbaikan formasi di sekitar sumur, serta adanya kenaikan tekanan selama produksi. Kenaikan tekanan ini menyebabkan PI aktual lebih besar daripada PI ideal. Dengan demikian, produksi di masa depan diperkirakan lebih tinggi dari yang diharapkan.

Abstract

Pipe sticking is an event where the drilling pipe is stuck or a fracture occurs. Usually what causes the pipe to be stuck or pinched is the viscosity in the mud is greater, causing the drill string movement to be hampered, it can also be caused by differential pressure or the fall of a foreign object into the drill hole. In this final project, a study will be carried out on the "AB" well because the drilling of this well experienced a pipe sticking problem. In writing this final project, 2 scenarios will be carried out, namely the calculation of Spotting Fluid using diesel and reducing the weight of the mud with the aim of reducing hydrostatic pressure. The pinch point has been found at a depth of 8083.99 ft. then for the handling, the weight of the mud is reduced in order to reduce the value of the hydrostatic pressure. In the bouyancy factor parameter, a value of 0.832 is obtained, then the density value of the drilling fluid is obtained in the table which is 82.29 lbs/ft3 Or 1318.159 kg/m3. And the total volume of the well obtained results of 284,557 bbl or 45,241 m3. In the spotting fluid method when the pipe sticking point has not been found, the diesel volume value is 41.25 bbl. In the mud weight reduction method when the pipe sticking point has been found, the mud weight reduction value is9.212 ppg. And obtained a differential pressure value of 63.255 psia. So that thebalance well and the pipe can be released.

Abstract

The “YDK-01” well has alkaline Formation Water with a pH value of 8,3. Therefore, Scale can form in the productive zone so that over time, Scale will continue to settle and be difficult to solved. From several Acidizing methods, Matrix Acidizing is the most recommended because in the wells examined there are indications of a positive Skin value (Formation Damage). Matrix Acidizing is a Reservoir stimulation method used to overcome Formation Damage in the wells caused by Scale. In this research, it is done using manual calculations using (Stiff & Davis), (Skillman, McDonald & Stiff) and Inflow Performance Relationship Wiggins equations, which aims to evaluate the problem of Scale. Changes in well production rates can be seen from a comparison of several parameters before and after Acidizing such as: Inflow Performance Relationship curve, Permeability value, Productivity Index value, and Skin. In the “YDK-01” well, there was an increase in the Qomax value of 47.16 bopd. The Productivity Index value of oil which was previously 0.129 bopd/psia, has changed to 0.198 bopd/psia. Permeability value has increased by 12 md and Skin value has decreased by 28.54. Parameters above prove that the Matrix Acidizing method works well in overcome scale on the well.

Abstract

This study aims to evaluate the performance of the C-3-08A separator used in a hydrocracking unit within an industrial processing facility, in support of increased production targets. The primary focus is to calculate and analyze the Area Ratio (Rm), which represents the ratio of the separator's length to its inlet diameter, ensuring efficiency in the fluid separation process at a flow rate of 13,435 BFPD. The method applied involves manual calculations to determine the Rm value and propose improvements to the separator design based on parameters such as length and flow rate. Analysis results show that the initial Rm value of 2.527 does not meet the standard requirement, which stipulates an Rm range between 3 and 5. Recalculation suggests that extending the separator length to 36 ft yields an Rm of 3.015, meeting the standard. Additionally, reducing the flow rate to 8,000 BFPD while maintaining a separator length of 30.183 ft and diameter of 10.045 ft produces an Rm of 3.004, also within acceptable limits. In conclusion, recalculating and adjusting the separator design parameters can enhance fluid separation efficiency and support increased production outcomes.

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.
