Abstract

Cumulative fluid production during 2009 - 2021 in the Betung Field, which is the research location and is located in the Jambi sub-basin-South Sumatra Basin (Barber et al., 2005), amounted to 277,923.52 MBbl. The relationship between porosity and permeability can be said in general that if the porosity is greater, the permeability will be greater, but in reality it will be found that certain layers will have large porosity but small permeability, such as in layers containing clay or shale. Mineralogical composition plays an important role, especially with regard to clays, involving several compositions including illite, smectite, kaolinite and chlorite. The presence of quartz and feldspar increases permeability, while clay minerals and calcite tend to have the opposite effect (Jose M. Carcione et al., 2019). The analysis carried out included XRD analysis to determine the mineral composition of the reservoir sandstone of the Airbenakat formation, rock quality analysis (porosity and permeability), well log analysis and then the overall analysis results were linked to production data. Based on XRD analysis, petrophysical analysis of wells 209 and 217 in the Betung field, Airbenakat formation, Jambi sub-basin, South Sumatra basin, the results of XRD and petrophysical analysis show the presence of clay content consisting of Kaolinite, Illite, Smectite and Chlorite which has an influence on reservoir quality, especially permeability, where the greater the clay content, the more obstructed fluid flow is.

Abstract

Sebagai negara yang berkembang pesat, Indonesia memiliki salah satu kebutuhan energi terbesar di dunia. Pada tahun 2021, Dewan Energi Nasional melaporkan konsumsi energi Indonesia pada tahun 2020 sebesar 118,3 MTOE, yang diproyeksikan meningkat menjadi 481,1 MTOE pada tahun 2050. Namun, hal ini diikuti dengan dampak Gas Rumah Kaca (GRK) yang semakin parah. Dampak bahaya emisi GRK telah meningkatkan urgensi pengurangan emisi dan dekarbonisasi. Bersama 197 negara, Indonesia berkomitmen membatasi kenaikan suhu hingga kurang dari 1,5°C dengan mengurangi emisi GRK. Pemerintah telah menyiapkan strategi yang diperlukan untuk mencapai net zero emission (NZE) pada 2050, dimana Carbon Capture Storage and Utilization (CCUS) akan memiliki peran yang vital. Volume penangkapan dan penyimpanan melalui CCUS akan tumbuh selama lima tahun ke depan, dari level sekarang sekitar 40 Mt CO2 per tahun menjadi 2,4 Gt CO2 pada tahun 2050. Namun, aplikasi CCUS dalam skala besar selama beberapa dekade terakhir masih dalam tahap adopsi awal yang rentan terhadap kegagalan. Selain itu, karena variasi ekonomi, politik, dan budaya, berbagai rintangan dalam proyek CCUS perlu dievaluasi dari satu tempat ke tempat lainnya. Pada paper ini, akan dilakukan studi kelayakan awal penerapan CCUS pada lapangan X di Indonesia berdasarkan tinjauan dari geosains, strategi pengembangan lapangan baik secara teknis maupun sosial, beserta analisis ekonomi proyek. Selain itu, akan dibangun project roadmap yang komprehensif dengan melakukan analisis framework, simulasi, beserta studi literatur untuk memastikan hasil penelitian yang dilakukan valid. Dengan studi yang terstruktur ini, diharapkan bahwa kelayakan prospek penerapan CCUS di Indonesia dapat dievaluasi secara keseluruhan.

Abstract

Proses pirolisis metana yang menghasilkan hidrogen tanpa melepaskan emisi CO2, sangat menjanjikan karena juga memproduksi hasil samping berupa karbon yang bermutu tinggi. Penggunaan logam cair sebagai media reaksi mampu memperbaiki proses konversi dan mengatasi masalah pengerakan pada reaktor kolom gelembung. Untuk mengetahui pengaruh suhu dan laju aliran gas terhadap konversi metana di dalam reaktor, dilakukan studi eksperimental di laboratorium. Hasil penelitian menunjukkan bahwa konversi gas metana meningkat ketika temperatur reaktor dan laju aliran gas menurun. Proses konversi gas metana tertinggi didapatkan pada suhu reaksi 1000°C dan laju aliran gas 50 ml/menit, yaitu sebesar 54,46%.

Abstract

Sistem hidrolika lumpur pemboran mempunyai peran yang sangat penting dalam opersi pemboran. Perencanaan dan pengontrolan yang baik dapat mempercepat operasi pemboran dan secara keseluruhan dapat menghemat biaya selama operasi pemboran. Peranan utama dalam sistem hidrolika lumpur pemboran yaitu untuk membersihkan lubang bor dengan mengangkat serbuk bor (cutting) sampai permukaan melalui annulus. Jika serbuk bor (cutting) yang mengendap tidak segera diangkat dapat menyebabkan beberapa masalah pemboran antara lain penggerusan serbuk bor berulang kali oleh pahat (regriding), tersangkutnya serbuk bor di sela-sela gigi pahat (bit balling), bahkan bisa memnyebabkan pipa terjepit (pipe sticking), dan juga hidrolika pahat yang tidak optimum dapat menjadi salah satu penyebab turunnya laju penembusan (ROP). Metode yang digunakan pada sumur “A” lapangan “M” yaitu menggunakan metode BHI (Bit Hydraulic Impact) dikarenakan sumur berarah. Prinsip dasar pada metode ini, menganggap bahwa semakin besar tumbukannya (tumbukan sesaat) yang diterima batuan formasu dari lumpur yang dipancarkan dari bit, maka semakin besar pula efek pembersihannya, sehingga metode ini berusaha untuk mengoptimalkan impact pada bit.            Evaluasi perhitungan hidrolika pada pahat yaitu Hal pertama yang dianalisa adalah BHI/HP pada optimasi hidrolika pada bit agar kita tahu apakah nilainya sudah optimal atau belum, nilai BHI/HPs optimum jika BHI/HPs > 48% kemudian menghitung nilai Ca yang optimum jika Ca < 5%, Ft yang optimum jika Ft ≥ 90% dan PBI yang optimum jika PBI ≥ 1.Kata Kunci: Hidrolika Pemboran, BHI, Pengangkatan Cutting.

Abstract

Plan an optimal geothermal well drilling scheme, the identification of suitable drilling parameters must be well known.Several important parameters in a drilling operation include rotary speed (N), weight on bit (WOB), true vertical depth (TVD), foamflowrate (FF), and rate of penetration (ROP). Information regarding these parameters can be obtained from drilling geothermal wells.Drilling parameter correlations are then obtained based on this information. The application of an adaptive neuro-fuzzy inferencesystem (ANFIS) is necessary considering that the relationship between parameters is very complicated and non-linear. On the other hand, the relationship between parameters is not easy to know. In this study, the ANFIS model is developed to propose ROP. Data wasobtained from four wells in a geothermal field in South Sumatra. Three ANFIS models were generated. Each model includes different input parameters. rotational speed (N) and weight on drill bit (WOB) and true vertical depth (TVD) are recommended for estimation of rate of penetration (ROP). Adding the foam flow (FF) input rate parameter can improve the accuracy in three out of four cases. Based on the calculation results of the ANFIS-1, ANFIS-2, and ANFIS-3 models, the average relative absolute deviation (MARE) values were 16.42%, 6.99%, 4.14%, respectively, while the correlation coefficient (R) was respectively - respectively 0.716, 0.909, and 0.937

Abstract

Geothermal is one of the renewable energies that is intensively developed during the energy transition. Indonesia is a country with the second largest geothermal potential in the world with a geothermal potential of 23,765.5 Mwe. The M.M.S.C.F field is classified as a volcanic geothermal system with liquid dominated developed with binary cycle technology. The use of conventional working fluid in binary cycle has low energy efficiency. Geothermal nanofluids particles consist of 2 or more nano-sized particles (1-100 nm), these particles are suspended and dissolved in the base fluid which can improve thermal conductivity and accelerate heat transfer in the heat exchanger. However, this technology has disadvantages including large Capital Expenditure (CAPEX) costs. This research applies CuO - Al2O3 to increase energy efficiency in heat exchangers directly proportional to the increase in thermal conductivity. The method used in this research is quantitative analysis by comparing economic indicators when using a conventional binary cycle system with a hybrid nanoparticle fluids binary cycle system in the M.M.S.C.F field heat exchanger and qualitative analysis based on previous literature studies. This technology has the advantage of increasing the heat transfer rate due to the increase in thermal conductivity value, the hybrid nanoparticle fluids thermal conductivity value is 0.79 W/m˚C when compared to the base fluid of 0.56 W/m˚C which has an increase of 23%. Based on the calculation of economic indicators, the payout time (POT) value as well as PI, IRR, and NPV of this technology are more positive than the conventional binary cycle. The effects of this research will be useful for the industry to improve the efficiency of the binary cycle.

Abstract

In drilling activities, wellbores inevitably experience deviation, commonly referred to as a crooked hole. If the deviation is significant, the loading on the drill string becomes one of the reasons why drilling does not go as planned and may even fail. The purpose of the research is to determine whether there is a deviation in the drilling path between the planned trajectory and the actual trajectory in well 'A-A' in the CPG field. By evaluating the drilling path deviation, it can be determined whether the load experienced by the drill string exceeds the predefined limits. The Minimum of Curvature method has the advantage of having minimal deviation and inclination, making it accurate with the plan. Therefore, this method is used to calculate the drilling path. Using the parameters of Measured Depth, Inclination, and Azimuth, the method will calculate the Radius Factor, Grid North, Grid East, Vertical Depth, and Vertical Section. The planned and actual data will then be compared to identify any deviation. Drill string load calculations will be performed if a deviation is found using the H. Rabia and Bill Mitchel equations to calculate Weight on Bit, Drag, Tension, Margin of Overpull, Torsion, and Buckling Load. The deviation results, such as at the Kick Off Point (KOP), show that in the plan, it is located at a depth of 1,378.02 Ft MD and 0.75 Ft Vsec, while in actual practice, it is at a depth of 1,275.65 Ft MD and -0.79 Ft Vsec. In Trajectory #1 for Surface Casing in the plan, it is at a depth of 2,067.03 Ft MD and 89.21 Ft Vsec, while in actual practice, it is at a depth of 1,963.68 Ft MD and 80.42 Ft Vsec. In Trajectory #2, the plan is at a depth of 3,724.52 Ft MD and 402.38 Ft Vsec, while in actual practice, it is at 3,695.72 Ft MD and 385.71 Ft Vsec.

Abstract

The Barito Basin in South Kalimantan, Indonesia, is a hydrocarbon-producing basin where the Eocene Tanjung Formation serves as both the primary source rock and reservoir. Despite historical discoveries, recent exploration has faced challenges in identifying high-quality reservoir rocks. This study evaluates the reservoir potential of the Lower Tanjung Formation in the Martapura area using fieldwork and laboratory analyses, focusing on porosity, permeability, and texture and depositional geometry. The formation comprises thick shale with minor sandstone and coal layers, interpreted to be deposited in an estuarine environment. Sandstone layers, 0.2–12 m thick, are limited in lateral extent, forming a narrow "shoestring" geometry. Porosity measurements range from 19.0% to 33.1% (good to very good), with an average of 24%, while permeability varies from 1.5 mD to 105 mD (tight to very good), averaging 29.7 mD. However, primary porosity of the sandstone (3.6–7.2%) is poor, with secondary porosity (3.6–14.8%) dominating, driven by near-surface weathering during uplift. Our study suggests that some sandstone layers exhibit good potential, but the overall reservoir quality is limited due to poor primary porosity and restricted depositional geometry.

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.
