Abstract

In producing oil and gas, Indonesia has two valid contract schemes, namely PSC Cost Recovery and PSC Gross Split. The IYP field is a field that has great potential in producing petroleum, with 25 workover and 2 infill wells. The scheme released to compare with the PSC Cost Recovery scheme is the Gross Split PSC scheme. The previous scheme was considered to be ineffective and still detrimental to the government. So the government issued Ministerial Regulation No. 52 of 2017 which is the result of a revision of Permen no. 8 of 2017. Gross Split PSC Scheme, the contractor bears all operational costs for the development of oil and gas fields. The economic research on the IYP field aims to compare the Cost Recovery PSC scheme with the Gross Split PSC.

Abstract

Metode Production Sharing Contract (PSC) telah dikenal di berbagai negara, termasuk Indonesia. Sistem PSC muncul sebagai respons terhadap kebutuhan agar pemerintah tidak hanya bersikap pasif tetapi juga memiliki peran yang lebih aktif dalam mengawasi operasional migas. Prinsip utama dalam skema PSC Gross Split adalah pembagian hasil produksi antara kontraktor dan pemerintah, di mana pemerintah tidak menanggung pengembalian biaya operasional dan tidak mempertimbangkan penggantian biaya Cost Recovery. Pendekatan ini juga bertujuan untuk mengurangi potensi konflik antara berbagai pihak. Penelitian ini bertujuan untuk membandingkan dua sistem kontrak berdasarkan indikator keekonomian serta analisis sensitivitas yang memengaruhi kedua sistem kontrak di lapangan CA. Penelitian ini dibatasi oleh data skenario pengembangan yang digunakan, yaitu skenario I. Skenario ini merupakan data base case yang mencakup data sumur produksi dengan tambahan satu kegiatan work over berdasarkan POD 2022. Analisis keekonomian di lapangan CA dilakukan menggunakan data yang diperoleh, diikuti evaluasi terhadap skenario yang ada, dengan memperhatikan harga minyak berdasarkan simulasi Monte Carlo dan referensi harga minyak terkini atau ICP. Hasil perhitungan dengan metode Gross Split menunjukkan bahwa nilai NPV kontraktor adalah 191,138 juta USD, dengan IRR sebesar 48,28%. Periode pengembalian investasi (POT) dengan metode Gross Split adalah 2 tahun, sementara tingkat pengembalian minimum yang dapat diterima (MARR) tercatat sebesar 25,84%.

Abstract

Cikarawang Village, Dramaga, Bogor is a village with a large potential for water resources. However, the water in this village has high levels of Mg2+ and Mn2+. High levels of Mg2+ and Mn2+ can cause eye and nose irritation, as well as influenza symptoms. To reduce the levels of Mg2+ and Mn2+ in water, this study used the adsorption method using activated carbon and bentonite. The results of the study showed that the levels of Mg2+ and Mn2+ in water can be significantly reduced using the adsorption method. In sample 1, the level of Mg2+ decreased from 14.64% to 11.64% after adsorption for 30 minutes. In sample 2, the level of Mg2+ dropped to 0% after adsorption for 30 minutes. In sample 3, the level of Mg2+ decreased from 9.60% to 5.76% after adsorption for 30 minutes. In general, the longer the contact time between the sample and the adsorbent, the greater the decrease in the levels of Mg2+ and Mn2+. However, for sample 2, the level of Mg2+ dropped to 0% after adsorption for 30 minutes. This indicates that sample 2 has a very high level of Mg2+ that can be adsorbed perfectly by bentonite in a short time. This study concluded that the adsorption method using activated carbon and bentonite is an effective method for reducing the levels of Mg2+ and Mn2+ in water.

Abstract

Hilangnya sirkulasi lumpur pemboran merupakan salah satu permasalahan penting yang sering terjadi dalam proses pemboran minyak dan gas bumi, di mana sebagian atau seluruh lumpur masuk ke dalam formasi bawah permukaan dan tidak kembali ke permukaan. Masalah ini dapat menyebabkan gangguan operasional, serta membahayakan stabilitas lubang bor. Penelitian ini bertujuan untuk menganalisis kasus kehilangan sirkulasi lumpur yang terjadi pada sumur SP di Lapangan Y pada kedalaman 1088 ft TVD. Metode yang digunakan meliputi analisis tekanan formasi, tekanan hidrostatik, tekanan rekah, tekanan formasi, serta evaluasi Equivalent Circulating Density. Hasil analisis menunjukkan bahwa tekanan sirkulasi yang terjadi melebihi tekanan rekah formasi, dengan nilai tekanan sirkulasi dasar lubang sebesar 577,691 psi, tekanan hidrostatik 497,87 psi, tekanan formasi 520,50 psi, dan tekanan rekah 568,02 psi. Kondisi ini menyebabkan terbentuknya rekahan buatan yang menjadi jalur hilangnya lumpur. Permasalahan ini dikategorikan sebagai partial lost dan berhasil ditanggulangi dengan aplikasi material penyumbat pada zona kehilangan menggunakan Lost Circulation Material. Penanganan yang tepat memungkinkan kegiatan pemboran dapat kembali dilanjutkan secara aman dan efisien.   Loss of drilling mud circulation is one of the important problems that often occurs in the oil and gas drilling process, where part or all of the mud enters the subsurface formation and does not return to the surface. This problem can cause operational disruption, as well as jeopardize borehole stability. This study aims to analyze the case of mud circulation loss that occurs in the SP well in Y Field at a depth of 1088 ft TVD. The methods used include analysis of formation pressure, hydrostatic pressure, fracturing pressure, formation pressure, and evaluation of Equivalent Circulating Density. The analysis results show that the circulation pressure exceeds the formation fracture pressure, with a hole bottom circulation pressure value of 577.691 psi, hydrostatic pressure of 497.87 psi, formation pressure of 520.50 psi, and fracture pressure of 568.02 psi. These conditions led to the formation of artificial fractures that became the pathway for mud loss. This problem was categorized as partial loss and was successfully addressed by the application of plugging material in the loss zone using Lost Circulation Material. Proper handling allowed drilling activities to resume safely and efficiently.

Abstract

Indonesia has a large amount of liquid waste originating from the tofu industry. Currently, the treatment of tofu industrial wastewater is carried out using both anaerobic and aerobic methods, but both methods still have several weaknesses. In this study, the tofu industrial wastewater was utilized as a culture medium for Spirulina sp. to provide economic value from wastewater that can be used as bioethanol, pharmaceuticals, and food products rich in omega 3, chlorophyll, carotenoids. Aim: The growth of Spirulina sp. is closely related to the availability of macro and micronutrients as nutrients and the influence of environmental conditions, so this study was aimed to see the best variation of the addition of urea and NaHCO3 as additional nutrients to maximize growth and cell density of Spirulina sp. with tofu industrial wastewater media. Methodology and Results: This study was done by culvitating Spirulina sp in the growth media, measuring the Optical Density (OD), and analyzing quantitatively and using ANOVA on IBM SPSS Statistics version 20. The study indicated that adding urea and NaHCO3 to Spirulina sp. had no effect on cell density and growth rate. Treatment with addition of urea 0.36 g/500 ml without additional of NaHCO3 had the highest growth rate, 0.00852/day, and the highest cell density value on Spirulina sp. growth. Conclusion, significance, and impact study: The tofu liquid waste can be used as a new alternative used as fertilizer because in the liquid tofu waste, it provides the nutrients needed by Spirulina sp.

Abstract

The world of oil cannot be separated from drilling operations in extracting hydrocarbons from below the earth's surface. Drilling mud or drilling fluid is essential to the drilling process. Cibinong Oil and Gas Vocational School is a vocational school that has two study programs, namely, Oil and Gas Drilling Engineering and Oil and Gas Production Engineering. The laboratory assistants at the Oil and Gas Vocational School have limitations in explaining in detail about drilling fluids. Therefore, activity is necessary to increase insight and knowledge of drilling fluids, especially in supporting practical activities. The method used in this activity is the dissemination of knowledge about drilling mud accompanied by the practice of making a simple drilling mud mixture. Making drilling mud is carried out by comparing KCl polymer mud and polyamine as a shale inhibitor. This comparison is seen from the results of the physical properties of the mud produced, namely mud weight, funnel viscosity, plastic viscosity, yield point, 10-second gel strength, 10-minute gel strength, filtration rate, mud cake, and pH (acidity level). With this introductory activity, knowledge about drilling fluids for laboratory assistants and chemistry teachers as participants in PkM activities has increased. This increase in knowledge can benefit students who will continue their education at the undergraduate level in earth sciences at universities.

Abstract

Drilling mud plays a vital role in maintaining wellbore stability, carrying cuttings, and controlling formation pressure during drilling operations. Typically, Carboxy Methyl Cellulose (CMC) is used to enhance mud viscosity and reduce filtration loss, but its synthetic nature makes it relatively expensive. This study investigates rice husk and sawdust as natural, cost-effective alternatives to CMC. Various compositions were evaluated using the Box-Behnken design in Response Surface Methodology (RSM) to optimize the mud formulation. Results indicate that a combination of 6 g rice husk and 6 g sawdust provides the best performance in improving rheological properties such as yield point and gel strength, while significantly reducing filtration loss. Gradual addition of caustic soda (NaOH) effectively increases mud pH to the ideal range (9–11), enhancing chemical stability. RSM successfully modeled the statistical relationship among variables and facilitated identification of the optimal formulation.

Abstract

Water-based drilling fluids commonly exhibit rheological degradation under high-temperature, high-pressure (HTHP) conditions, resulting in significant reductions in viscosity, yield point (YP), and gel strength (GS). Previous studies relying on conventional additives such as PAC, CMC, KOH, and NaOH have not fully resolved this issue, particularly in maintaining rheological stability at elevated temperatures. This study addresses this gap by introducing an alkaline polymer as a multifunctional additive intended to replace several conventional components while enhancing thermal resistance. Response Surface Methodology (RSM) with a Box–Behnken design was used to evaluate the combined effects of Carboxymethyl Cellulose (CMC) and alkaline polymer at three temperature levels: 80°F, 150°F, and 250°F. Experimental results show that at 150°F, the optimized formulation consists of 3.5 g CMC and 3.6 g alkaline polymer, yielding a viscosity of 17.64 cP, plastic viscosity of 12.46 cP, and a YP of 7.72 lb/100 ft², representing a substantial improvement compared to the baseline formulations, where YP values decreased significantly with temperature. The optimized mud also demonstrated improved gel strength and consistent filtrate control relative to non-optimized systems. The novelty of this study lies in the use of an alkaline polymer as a single multifunctional substitute for multiple drilling-fluid additives, combined with a multi-temperature RSM optimization framework. The findings provide a simplified, thermally stable drilling-fluid formulation suitable for HTHP environments.
