Abstract

The Willow Project is located on Alaska's north slope, within the National Petroleum Reserve, which is held by the United States federal government. Based on the topics being discussed, a strong desire was developed, particularly among Yos Sudarso Metro High School students, to learn about the causes for oil drilling, as well as the impacts and benefits of drilling from diverse perspectives. Concerning the community service that according to Willow Project theme, the lecturers as the facilitators of this community service assisted students who wanted to find a solution to the Willow Project issue, where they hoped that there would be several points regarding the impact and benefits of academia in the energy sector, particularly petroleum engineering. As a result of socialization regarding the Willow Project drilling, impacts and benefits have been imparted in the Community Service activities, which are separated into environmental impacts, climate impacts, and social impacts. Following an overview of the impact of the Willow Project drilling, the benefits of the drilling are explained, including job creation and economic benefits, energy independence, and tax revenue. The crux of the impacts and benefits given is that it is still envisaged that fossil energy would be used to increase jobs in the nearby community and globally. Aside from that, it is desired that the development of renewable energy, the reduction of drilling in conservation areas, and the preservation of environmental integrity would continue.

Abstract

Peningkatan emisi karbon dari sumber bahan bakar fosil telah mendorong pemerintah Indonesia untuk berkomitmen mengurangi emisi gas karbon dioksida (CO2) yang berasal dari penggunaan bahan bakar fosil, sebagai bagian dari upaya mitigasi perubahan iklim. Mengetahui kapasitas CO2 yang dapat tersimpan dalam reservoir, mengetahui penentuan sumur yang layak untuk dilakukan CO2 storage, mengetahui mekanisme CO2 terhadap perangkap solubilitas didalam reservoir. Dalam penelitian ini diawali dengan pengumpulan data berupa data reservoir data fluida reservoir dan data grid, setelah itu melakukan input data dan juga pemodelan reservoir menggunakan aplikasi T-Navigator setelah itu melakukan matching data dan juga menganalisa injeksi CO2 storage yang terperangkap. Hasil output yang didapat ada produksi tanpa adanya injeksi itu sebesar 15.20 Bscf, produksi yang terdapat injeksi 16.13 Bscf, dan CO2 yang terperangkap. Setelah itu terdapat 3 case yang didapat dikedalaman yang berbeda case 1 dikedalaman 4000 ft terperangkap total sebesar 2.1 MMTCO2 kemudian case 2 dikedalaman 4500 ft terperangkap total sebesar 1.63 MMTCO2 dan yang terakhir case 3 dikedalaman 5200 ft terperangkap total sebesar 0.95 MMTCO2. Terdapat tiga skenario untuk yang paling bagus untuk storage ialah pada case yang pertama dikedalaman 4000 ft karena memiliki paling banyak gas yang terperangkap sebesar 2.1 MMTCO2 dari pada kedua case yang lainnya. Pada reservoir migas yang sudah mengalami penurunan, maka dapat menyimpan CO2 karena masuk dalam salah satu kriteria yang dapat menyimpan CO2. Pengaruh CO2 yang terperangkap di reservoir itu terdapat dua hal, ada yang terperangkap oleh struktural trapping dan ada yang terlarut oleh air di reservoir tersebut.

Abstract

Deliverability tests are used to evaluate a well's production capability by estimating the Absolute Open Flow Potential (AOFP) and maximum flow rate. The three main methods applied are the Flow-after-flow Test, Isochronal Test, and Modified Isochronal Test. For the YA-01 gas well, the Flow-after-flow Test was used, which involves steps such as data compilation, plotting, calculation of the inverse slope (n), and determination of the AOFP and maximum flow rate (Qmax). Software analysis results indicated an inverse slope (n) of 1.19226, a C value of 0.000000418 MSCFD/psia², an AOFP of 12,930 MSCFD, and a Qgmax of 3,879 MSCFD. For verification, a manual analysis using the Rawlins-Schellhardt and Horner methods with a pseudo-pressure approach was conducted, yielding an AOFP value of 12,850 MSCFD. The combination of software and manual results provides a comprehensive and accurate understanding of the well conditions, supporting production optimization decisions and evaluating the effectiveness of the acidizing process.

Abstract

Indonesia's oil and gas sector has traditionally employed Production Sharing Contracts (PSCs) to regulate the sharing of revenues between the government and contractors. Two key PSC models are used: PSC Cost Recovery and PSC Gross Split. The PSC Cost Recovery model allows contractors to recover their exploration and production costs before profits are shared, providing financial protection but reducing long-term profitability. Conversely, the PSC Gross Split model, introduced in 2017, offers a simpler revenue-sharing mechanism, eliminating cost recovery and directly splitting gross revenue between the government and contractors. This study analyzes the financial implications of both models using economic simulations, focusing on key indicators like net cash flow, net present value (NPV), pay-out time, and discounted cash flow (DCF) rate of return. Results show that the Gross Split model generates significantly higher gross revenue ($420.908 million) than Cost Recovery ($46.362 million), but at the cost of greater financial risks for contractors due to higher upfront investments and operating costs. The Gross Split model also provides higher long-term returns, with a net cash flow of $67.138 million compared to $8.252 million in Cost Recovery. However, the pay-out time is longer, and the DCF rate of return is slightly lower (29.95% vs. 31.8%). Ultimately, PSC Gross Split is more suited for contractors with higher risk tolerance and capital resources, while PSC Cost Recovery may be preferable for smaller contractors seeking to minimize financial risks. Both models offer distinct advantages depending on the contractor’s financial capacity and risk appetite.

Abstract

One physical characteristic that is helpful in comprehending the physical and chemical characteristics of a solution is the density of the polymer solution. Its primary function is to ascertain the polymer's concentration in solution. The density value can be used to estimate the polymer concentration in solution. The study of the flow and viscosity of polymer solutions also makes use of the interaction between the polymer and solvent. This study aims to establish a relationship between the density of porang and xanthan gum solutions and the percentage of porang, polymer content, and salinity. Machine learning models, like the Adaptive Neuro Fuzzy Inference System (ANFIS) and Artificial Neural Network (ANN), are used for modeling. The creation of these machine learning models used 471 digitized data of density curves of porang solution, xanthan gum solution, and porang-xanthan gum mixture solution. The training, validation, and testing processes of the ANN and ANFIS models provided average correlation coefficients of 0.99955 and 0.99999, respectively. Comparison between the estimates of the ANN and ANFIS models and the measurement results of 27 porang and xanthan gum solutions provided accurate results with correlation coefficients of 0.99893 and 0.99996, respectively.

Abstract

City gas network socialization is a community service that aims to make community understand the development of the city gas distribution sector in Indonesia and provide information to the community about liquified petroleum gas (LPG) substitute. A gas network for households means distributing gas through pipes to households. The limited availability of household gas in DKI Jakarta made this socialization theme raised. The location chosen is the Tanjung Gedong area, Tomang-sub district, Grogol Petamburan district, West Jakarta, which in this case, the area is a densely populated area, especially family settlements. The participants who took part in this community service were housewives. The method used is to provide socialization about the city gas network developed by the government for household gas purposes, the socialization is carried out online with the zoom facility and some others offline in the community while still using the existing health protocol. The result of this community service activity is that the community can recognize and understand the existence of a gas network whose infrastructure development is being developed by the government through PT Perusahaan Gas Negara (PGN) Tbk. This community service makes the community aware of the flow of the city gas network development program.

Abstract

Penelitian ini bertujuan untuk mengevaluasi perubahan saturasi dalam reservoir dan mengidentifikasi fenomena di sekitar lubang sumur yang mempengaruhi saturasi pada sumur BT-1, menggunakan metode pulsed neutron capture (PNC) sigma. Dengan memanfaatkan data yang diperoleh, penelitian ini bertujuan untuk memberikan informasi yang lebih komprehensif dan akurat tentang kondisi reservoir, untuk mendukung pengelolaan reservoir minyak dan gas bumi yang lebih efektif. Metode yang digunakan melibatkan analisis petrofisika dengan memasukkan data log GR, Rt, Rxo, NPHI, dan RHOB ke dalam software Interactive Petrophysics (IP). Setelah identifikasi litologi batuan dengan crossplot RHOB dan NPHI, dilakukan interpretasi kuantitatif untuk menentukan volume shale, porositas efektif, dan saturasi air (Sxo dan Sw) sebelum casing sumur ditutup. Estimasi perubahan saturasi selama produksi sumur menggunakan data dari sigma. Analisis ini dilakukan dengan menggunakan software IP. Sumur BT-1 memiliki empat zona perforasi dengan interval masing-masing dari kedalaman 11613 ft hingga 12325 ft. Hasil basic log analysis menunjukkan nilai rata-rata Volume clay 4,5%, porositas efektif 15,1%, Sxo 56,7%, dan Sw 5,8%. Evaluasi menunjukkan peningkatan saturasi selama periode penutupan sumur, terutama di interval 11811 ft hingga 12087 ft, disebabkan oleh aliran air yang besar yang mempengaruhi proses produksi minyak. Kesimpulan menunjukkan peningkatan saturasi disebabkan oleh fenomena eksternal, bukan dari dalam reservoir, seperti yang ditunjukkan oleh Water Flow Log (WFL), dengan minyak yang berhasil diproduksi tanpa terjadi bypassed oil

Abstract

Penelitian ini menggunakan metode material balance dengan software IPM-MBAL untuk mengestimasi cadangan minyak di Lapangan Z secara akurat dan tepat. Penelitian bertujuan menghitung Original Oil in Place (OOIP), mengidentifikasi mekanisme penggerak reservoir, serta menentukan Remaining Reserves (RR), Estimated Ultimate Recovery (EUR), dan Recovery Factor (RF). Langkah ini penting mengingat meningkatnya kebutuhan energi dan menurunnya produksi dari sumur tua. Metode material balance dilakukan dengan menganalisis data tekanan reservoir, produksi kumulatif minyak dan air, serta parameter PVT dari 19 sumur aktif. Analisis menggunakan software IPM-MBAL melalui proses PVT matching untuk mendapatkan parameter fluida akurat dan history matching untuk mengestimasi OOIP serta mekanisme penggerak reservoir. Maka hasil penelitian menunjukkan nilai OOIP sebesar 47,9 MMSTB, dengan deviasi kurang dari 5% dibandingkan estimasi volumetrik sebelumnya sebesar 45,7 MMSTB. Mekanisme penggerak utama yang teridentifikasi adalah water drive, berdasarkan analisis energi reservoir dan metode Ganesh Thakur. Selain itu, Recovery Factor (RF) tercatat sebesar 42%, dan Remaining Reserves (RR) dihitung mencapai 1,38 MMSTB. Kesimpulannya yaitu metode material balance berbasis IPM-MBAL memberikan hasil estimasi yang akurat. Penelitian ini berkontribusi pada pengelolaan reservoir yang lebih efektif serta pengambilan keputusan strategis dalam pengembangan lapangan. Pemahaman yang lebih baik tentang cadangan minyak dan mekanisme penggerak reservoir mendukung efisiensi pengelolaan sumber daya hidrokarbon secara berkelanjutan.
