Abstract

The assessment of geothermal well production capability plays a crucial role in optimizing geothermal energy generation systems. This study focuses on evaluating the performance of two geothermal wells, ZM-42 and ZM-31, located in the AAP Field, by developing output curves through wellbore simulation techniques. The analysis utilizes field production test results, well casing configuration data, and PTS (Pressure, Temperature, and Spinner) survey data to generate key parameters such as wellhead pressure, fluid flow rate, fluid temperature, enthalpy, and vapor fraction (dryness). These parameters are essential for understanding the thermal and flow characteristics of each well. Wellbore simulations were conducted using specialized software to replicate the flow behaviour of geothermal fluids within the well system. The output curves produced provide a graphical representation of the relationship between wellhead pressure and mass flow rate under various operating conditions. Validation of the simulation was done by comparing the generated curves with actual field measurements. The results show that well ZM-31 demonstrates a higher production capability compared to ZM-42. ZM-31 recorded a flow rate of 96.61 kg/s and an enthalpy of 1134.5 kJ/kg, with a vapor fraction of 0.14. In contrast, ZM-42 exhibited a lower flow rate of 85.60 kg/s, enthalpy of 1027.7 kJ/kg, and a vapor fraction of 0.11. These differences indicate superior separation efficiency and thermal performance in ZM-31. Furthermore, ZM-31’s production is dominated by a single feed zone, while ZM-42 relies on multiple contributing zones. In conclusion, based on output curve analysis and well simulation results, ZM-31 is recommended as the primary production well for further optimization in the AAP geothermal field, contributing to more efficient and reliable energy output.

Abstract

Lapangan NM merupakan salah satu lapangan minyak tua yang mengalami penurunan tekanan reservoir, sehingga diperlukan sistem pengangkatan buatan seperti Electric Submersible Pump (ESP) untuk mempertahankan produksi. Penelitian ini bertujuan mengevaluasi dan mengoptimalkan kinerja ESP di Sumur A melalui analisis efisiensi lifting dan efisiensi reservoir. Hasil awal menunjukkan efisiensi lifting hanya sebesar 30,46% dan efisiensi reservoir 61%, yang keduanya berada di bawah ambang batas minimal 70%. Optimasi dilakukan dengan mengganti tipe pompa dari TD-460 menjadi TD-150, menghasilkan peningkatan efisiensi lifting menjadi 70,58% dan efisiensi reservoir menjadi 76,9%. Studi ini menekankan pentingnya pemilihan jenis pompa yang tepat dan pemantauan berkala untuk meningkatkan kinerja produksi pada sumur-sumur tua.   NM Field is a mature oil field experiencing reservoir pressure decline, requiring artificial lift systems such as Electric Submersible Pumps (ESP) to maintain production.

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

The waste diapers, the second largest waste source after plastic, pose environmental challenges due to their slow degradation of 25-50 years. Reprocessing diaper waste, including utilizing Super Absorbent Polymer (SAP), is crucial. SAP's high absorption capacity aids in research for separating crude oil from water, particularly relevant for Indonesian oil wells with aging infrastructure. Emulsions in crude oil, stabilized by natural chemicals, require demulsification to prevent production issues, underscoring the importance of efficient water-oil separation methods. The research experimentally compares oil-in-water emulsion separation using SAP with and without SAP. The study utilizes waste-based ingredients like used diapers, and tests involve centrifuge processes at varying temperatures. SAP's osmotic properties enable high water absorption, impacting demulsification efficiency. This study investigates the impact of temperature on emulsion separation between water and crude oil. Testing at 26°C and 40°C reveals accelerated separation at higher temperatures due to reduced crude oil viscosity. Waste-containing tubes demonstrate better separation, with SAP absorbing water, enhancing separation efficiency. Increasing centrifuge speed and temperature improve oil-water separation, showcasing SAP's effectiveness in waste management processes. Research findings on crude oil-water separation using diaper waste conclude that demulsification is faster at 40°C due to decreased viscosity; with SAP waste, volumes of water are more efficient at 40°C; SAP's hydrophilic nature traps water in the gel network; SAP enhances separation effectiveness compared to non-SAP methods in saline solutions.

Abstract

This community service program titled "Socialization and Training on the Utilization of Solar Energy as an Environmentally Friendly Electricity Source in Karang Taruna, Gambir District" aimed to address the critical issues faced by the community due to their heavy reliance on unstable and costly fossil energy from PLN (the state-owned electricity company). The program also targeted the low understanding and practical skills related to solar energy and the underutilization of solar energy potential in urban settings. The implementation comprised two core components: socialization of solar energy and climate change impacts, and hands-on training on mini solar panel systems. Using interactive lectures, demonstrations, direct practices, and discussions, the program was conducted on March 16, 2025, involving 31 participants mainly from Karang Taruna members. A significant improvement in participants’ comprehension was observed, with average pre-test scores rising from 45 to 82, indicating an 82.22% increase. Furthermore, participant satisfaction reached 90.32%, alongside a 70.96% enhancement in practical ability to operate mini solar panel setups. Key outputs included teaching materials, posters, and scientific articles, collectively contributing toward enhanced community energy independence, reduced electricity costs, and promotion of clean energy adoption in urban areas.
