Abstract

Indonesia merupakan negara dengan potensi panas bumi yang besar, dengan posisi negara yang terletak di cincin vulkanik menjadi Indonesia sebagai negara yang memiliki banyak tempat sumber panas bumi. Sumber panas bumi merupakan energi terbarukan yang dapat dikelola menjadi energi listrik, akan tetapi dalam proses produksinya masih banyak tantangan dan kendala dalam pengembangan energi panas bumi ini. Pada pengembangannya dibutuhkan metode yang efektif dalam menangani masalah yang ada dan mengoptimalkan produksi energi panas bumi. Penelitian ini ditujukan untuk membahas dan mereview salah satu metode peningkatan produksi energi panas bumi yaitu metode enhanced geothermal system (EGS). Metode stimulasi EGS dapat mengatasi beberapa kendala seperti permeabilitas kecil dan dapat memproduksi energi panas bumi pada hot dry rock (HDR). Pada EGS diterapkan fracking untuk memperbesar permeabilitas, hydroshearing juga dapat diterapkan pada EGS. Penelitian ini dilakukan dengan metode studi literatur dan mengumpulkan data dari beberapa artikel penelitian terdahulu yang berhubungan dengan EGS. Berdasarkan studi literatur, metode EGS sudah banyak diterapkan di beberapa negara di dunia. Indonesia juga sudah mulai melakukan penelitian mengenai penerapan metode EGS ini yang dilakukan di lapangan Kamojang dan Dieng. Keywords: Enhanced Geothermal System, EGS, Fracking, Hydroshearing

Abstract

Development of supercritical geothermal technology is a complex and challenging process that requires significant investment in research, technology development, and collaboration. However, the potential benefits of this technology include low carbon footprint, high efficiency, and the potential to provide reliable electricity, making it an important focus area for the future of clean energy production. This study is qualitative and uses literature study methods involving data collection and analysis from various literature sources, including scientific journals, books, and reports. The literature study was conducted by searching and collecting several relevant and accurate sources such as scientific journals, books, and official publications on the topic. Data collection was carried out by analyzing the content of each available source. The supercritical geothermal well drilling method can generate electricity of 3-5 MW per well. Several successful energy development projects include exploration well drilling in Mexico, Italy, Iceland, USA, Kenya, and Japan. Supercritical energy development technology is also continuously being developed, such as closed-loop and CO2 utilization.

Abstract

Well X started production on February 9th, 2012 with oil production of 217 BOPD and peak production on March 1th, 2012 with oil production of 2756 BOPD. As production progresses, the reservoir pressure will decrease resulting in a decrease in the production rate. Well X was shut-in on March 7th, 2023 with oil production of 197 BOPD and watercut reaching 91.27%. The location of this study is administratively located in Campurejo Village, Bojonegoro District, Bojonegoro Regency. Analysis of well potential and well forecasting are carried out by the Wiggins method. This method was chosen because the X well has a three-phase fluid and a high water cut. The calculation results show a maximum flow rate of 4111.52 BFPD and an optimum flow rate of 2466.91 BFPD. After calculating the optimum flow rate, and to avoid water cloning, it is recommended that wells be produced with a production flow rate of 2412.54 BFPD at a well base flow pressure (Pwf) of 1368 Psi.

Abstract

The research focuses on evaluating the production performance of three oil wells-Well F55A MB, Well Hovea 13 ST1, and Well Pedirka-1-using Inflow Performance Relationship (IPR) and Vertical Lift Performance (VLP) analysis to determine optimal artificial lift methods for each case. The study explores critical production parameters such as reservoir pressure, temperature, and gas-to-oil ratio (GOR) while employing decision tree methodologies to select suitable artificial lift systems. For Well Hovea 13 ST1 and Well Pedirka-1, gas lift installations significantly enhanced oil recovery rates by optimizing injection pressures and valve placements, achieving production gains of 694 and 300 barrels per day, respectively. In contrast, Well F55A MB, characterized by high water cut and lower reservoir temperatures, was deemed unsuitable for artificial lift based on the decision tree analysis, with a stable production of 2832 stb/d. This work highlights the importance of tailored artificial lift strategies for maximizing oil recovery and improving well performance in diverse reservoir conditions.

Abstract

Indonesia tercatat sebagai salah satu negara penyumbang emisi gas CO₂ terbesar di dunia dengan total emisi mencapai 1,3 Gt di mana 50,6% berasal dari sektor industri migas. Oleh karena itu, Pemerintah Indonesia berkomitmen untuk menurunkan emisi GRK sebesar 29%. Penelitian ini bertujuan untuk mengurangi emisi GRK dengan menerapkan sistem carbon pricing pada perhitungan keekonomian dan penggunaan metode injeksi gas CO2 pada reservoir X. Selain itu, metode injeksi CO2 diharapkan nantinya dapat mengoptimalkan produksi minyak pada reservoir. Injeksi CO₂ di reservoir X dan penerapan sistem carbon pricing menggunakan skema Production Sharing Contract (PSC) Gross Split dirancang dengan data asumsi yang memiliki karakteristik minyak ringan (°API 35) dan batuan sandstone dengan kedalaman 10.000 ft. Pada awal produksi, reservoir X mengalami penurunan yang signifikan akibat aquifer support yang lemah, sehingga diterapkan Enhanced Oil Recovery (EOR) dengan injeksi CO₂ secara miscible dan immiscible. Penelitian ini menggunakan 3 skenario yang nantinya disimulasikan dan dibandingkan hasil perolehan terbaik. Skenario 3 merupakan skenario terbaik dengan menginjeksikan 1 sumur produksi dan 2 sumur injeksi yang menunjukkan peningkatan kumulatif produksi minyak lebih besar dari simulasi basecase, diperoleh nilai sebesar 7,6 MMBBL dengan recovery factor sebesar 55% dan penurunan water cut hingga 91%. Selain itu, hasil perhitungan keekonomian dengan menerapkan sistem carbon pricing menghasilkan NPV sebesar 786.678,21 USD, IRR sebesar 11%, dan Pay Out Time (POT) selama 7,4 bulan yang mengindikasikan kelayakan ekonomi proyek bagi kontraktor. Penelitian ini memberikan triple-win solution dengan meningkatkan produksi minyak, mendukung target nasional pengurangan emisi karbon, dan memberikan keuntungan ekonomi.
