Abstract

Our oil and gas exploration must be able to understand the concept of the petroleum system. Source rock is one of the most important parameters in the petroleum system that functions as a hydrocarbon producer or source rock, even placing the bedrock as the number one priority that must be present in the petroleum system (Magoon and Dow, 1994). This study aims to determine the potential of parent rocks in the Upper Talang Akar Formation in the research area to produce hydrocarbons. The research method was carried out using surface samples, geochemical analysis of Total Organic Carbon, Rock-Eval Pyrolysis and Vitrinite Reflektance. Based on the results of geochemical analysis research that has been carried out on the source rock of the Upper Talang Akar Formation, the characteristics of the potential of the source rock in producing hydrocarbons have a rich organic material range (1.38 – 4.06), based on TOC data, the sample of the source rock of the Upper Talang Akar Formation has quite good potential. Analysis of organic material types in the study area's source rock samples yielded kerogen types II and III that have the potential to produce oil and gas hydrocarbons. The maturity level analysis is based on Tmax data of the Upper Talang Akar Formation source rock has an immature maturity level and based on Ro data, the upper Talang Akar of the source rock has an immature maturity level. Therefore, it can be concluded that the shale source rock of the Upper Talang Akar Formation in the research area has the potential to produce good to very good hydrocarbons and produce oil and natural gas in the immature phase.

Abstract

Sumur “X” terletak di lapangan Jawa Tengah merupakan sumur mature yang diproduksi dengan Sucker Rod Pump dengan laju alir sebesar 120 Bpd. Tujuan penelitian ini adalah untuk meningkatkan produksi sumur dengan melakukan optimasi pada sucker rod pump serta menurunkan intensitas emisi karbon yang dihasilkan. Metode yang digunakan meliputi, membuat kurva inflow performance relationship dengan metode vogel, evaluasi sucker rod pump, optimasi dan efisiensi sucker rod pump.  Hasil penelitian ini adalah sumur “X” masih berpotensi ditingkatkan nilai produksinya hingga 457,35 bpd dengan laju alir optimum sebesar 365,88 bpd. Evaluasi terhadap kinerja sucker rod pump yang terpasang saat ini menunjukkan performa yang tidak efisien, ditandai dengan nilai efisiensi volumetrik sebesar 41%, rendahnya efisiensi ini berdampak pada tingginya konsumsi energi spesifik, dengan intensitas emisi karbon mencapai 455,72 gCO2/barrel. Jika dilihat dari kemampuan sumur yang berpotensi, maka optimasi dan efisiensi dilakukan untuk mendapatkan pompa yang ideal. Hasil konfigurasi operasi terbaik dicapai pada kombinasi SL = 64 inci dan N = 11 SPM. Parameter ini terbukti aman karena beban dan torsi yang dihasilkan masih berada di bawah batas maksimum spesifikasi pumping unit terpasang. Selain itu, skenario ini mampu meningkatkan efisiensi volumetris secara signifikan dari 41% menjadi 95%. Dari sisi lingkungan, meskipun total emisi harian meningkat seiring dengan kenaikan volume produksi, namun intensitas emisi turun drastis dari 455,72 gCO2/barrel menjadi 205,60 gCO2/barrel. Hal ini membuktikan bahwa optimasi parameter operasi berhasil membuat sistem pengangkatan fluida menjadi jauh lebih efisien dan hemat energi per unit produk yang dihasilkan.

Abstract

Abstrak: Penelitian ini mengusulkan kerangka kerja eksplorasi hidroenergi regional yang mengintegrasikan analisis gradien energi berdasarkan DEM, estimasi debit andalan melalui Flow Duration Curve (FDC) yang diturunkan dari neraca air spasial berbasis produk satelit, yaitu Global Precipitation Measurement Integrated Multi-satellite Retrievals for GPM dan Model Operasional Simplified Surface Energy Balance (GPM IMERG dan SSEBop), serta evaluasi geologi-geomorfologi untuk mengindentifikasi segmen sungai yang optimal bagi pengembangan PLTA/PLTM run-off-river. Metode multi-kriteria (GIS_MCE) yang diusulkan menyatukan indikator teknis dan tekno-ekonomi awal (design discharge, net head, LCoE, NPV, IRR) dengan bobot yang mencerminkan prioritas investor. Studi kasus di area Semende , Sumatera Selatan, menunjukkan bahwa kombinasi gradien energi tinggi dan litologi lunak atau akses buruk menunjukkan biaya konstruksi dan Levelized Cost of Energy (LCoE) yang tidak kompetitif. Kerangka ini dapat menjadi alat screening valid untuk memfokuskan survei lapangan dan menurunkan biaya pre-feasibility.  Abstract: This study proposes a regional hydroenergy exploration framework that integrates energy gradient analysis based on DEM, reliable discharge estimates derived from Flow Duration Curves (FDC) using satellite-based spatial water balances Global Precipitation Measurement Integrated Multi-satellite Retrievals for GPM and Model Operational Simplified Surface Energy Balance (GPM IMERG and SSEBop), and geological-geomorphological evaluation to identify river segments optimal for run-off-river hydroelectric power plant (HPP) development.  The proposed multi-criteria method (GIS-MCE) combines initial technical and techno-economic indicators (design discharge, net head, LCoE, NPV, IRR) with weights that reflect investor priorities. A case study in the Semende Area, South Sumtaera, shows that the combination of a high energy gradient and competent volcanic lithology yields the highest feasibility score, whereas locations with soft lithology or poor access exhibit uncompetitive construction costs and Levelized Cost of Energy (LCoE). This framework can be a valid screening tool to focus field surveys and reduce pre-feasibility costs.

Abstract

Reservoir TGB is a sandstone reservoir that began production in December 2019 and, as of November 2024, has been developed by two producing wells with a cumulative oil production of approximately 374 MSTB. Along with the increasing production activities and the need for field development planning, an evaluation of hydrocarbon reserves is required to assess the reservoir’s future production potential. This study aims to determine the Original Oil in Place (OOIP), identify the reservoir drive mechanism, and estimate the Estimated Ultimate Recovery (EUR) and remaining reserves of Reservoir TGB using the material balance method. The material balance analysis was conducted using oil, gas, and water production data, reservoir pressure data, and fluid property (PVT) data. History matching was performed using MBAL software to achieve consistency between the reservoir model and actual production behavior. Furthermore, the reservoir drive mechanism was evaluated through energy plot analysis and reservoir performance assessment. Decline curve analysis was subsequently carried out using OFM software to estimate the productive life and ultimate recovery potential of the reservoir. The results indicate that the OOIP of Reservoir TGB is approximately 3,000 MSTB. The evaluation of the drive mechanism shows that the reservoir is dominated by a water drive system. Based on the decline curve analysis, the EUR is estimated at 613.7 MSTB, with remaining reserves of 239.08 MSTB and a recovery factor of approximately 20.46%. These results indicate that a significant portion of hydrocarbons remains unrecovered. Therefore, further field development through the addition of production wells is recommended to improve oil recovery and optimize the utilization of the remaining reserves in Reservoir TGB.

Abstract

Run-of-river hydropower development has increasingly attracted attention as part of Indonesia's renewable energy transition. However, many projects encounter challenges due to insuffisient integration of sustainability aspects, particurlarly Environmental, Social, and Governance (ESG) considerations. Geohazard risks such as landslides, flash floods, and tectonic activity, along with environmental impacts including erosion, sedimentation, and land cover change, are often overlooked during the early planning stages. This research aims to develop a GIS-based ESG risk assement framework using a Multi Criteria Evaluation (MEC) approach. The variables considered include geohazard factors (slope, lithology, rainfall, active faults) environmental factors (land cover change, erosion potential, habitat conditions), and socio-economic factors (proximity to settlements, inftasructure, and land use patterns). The datasets used include Digital Elevation Model (DEM), geological maps, sattelite imagery, demographic and infrastructure data. The expected results are an ESG risk index and spatial risk maps that can prioritize sustainable sites for run-of-river hydropower development. This approach is anticipated to help developers, consutants, and policymakers identify projects that are not only technically and financially viable but also geohazard-reslient, environentally sound, and socially acceptable.

Abstract

Electrofacies clustering is fundamental to reservoir characterization but is often hindered by the subjectivity and inefficiency of conventional manual interpretation, particularly in heterogeneous fields. This study presents a robust, data-driven workflow for automating electrofacies identification using unsupervised machine learning, applied to Gamma Ray (GR) logs from 66 wells across 16 reservoir intervals in the NVS Field, Central Sumatra Basin. The methodology systematically evaluates the impact of feature representation by comparing Statistical, Convolutional Neural Network (CNN), and Long Short-Term Memory (LSTM) extraction techniques coupled with K-Means, BIRCH, and Gaussian Mixture Model (GMM) clustering algorithms. Performance assessment using Silhouette scores and the Davies-Bouldin Index demonstrates that LSTM-based features consistently yield superior clustering results by capturing critical sequential log-shape dependencies essential for resolving vertical heterogeneity. While algorithmic efficacy was found to be context-dependent—with GMM favoring transitional facies and K-Means excelling in high-contrast zones—the integration of the optimal models successfully reconstructed geological patterns without prior labeling. External validation against reference facies maps confirmed that the unsupervised clusters exhibit strong spatial coherence, accurately delineating the Northwest-Southeast (NW-SE) depositional trend of Tidal Bar Axis and Margin zones. Furthermore, the model demonstrated high geological sensitivity by successfully identifying localized features such as Isolated Sand Bars. These findings verify the geological plausibility of the proposed workflow and underscore the necessity of sequence-aware feature extraction, offering a reproducible and objective framework for reservoir modeling in data-limited environments.

Abstract

The cement squeeze operation is an important remediation method for repairing casing leaks and restoring zonal isolation in problematic wells. This study aims to evaluate the performance of cement slurry used in cement squeeze operations under High Temperature High Pressure (HTHP) conditions through rheological, thickening time, and compressive strength tests. The slurry formulation utilized API Class G cement enriched with 35% BWOC silica flour (SCSR-75), with the addition of antifoam (SAL-01L), dispersant (SCD-01L), fluid loss additive (SFL-01L), gas block additive (SBA-01L), and high-temperature retarders (SRD-01L and SRD-05L) to maintain stability during pumping and setting. Rheological testing indicated that the slurry exhibited stable flow behavior, with acceptable plastic viscosity for both the lead and tail slurries, demonstrating good pumpability without loss of stability. Thickening time tests showed a setting time of 6–7 hours at 216 °F, which remains within a safe operational window for pumping. Meanwhile, compressive strength testing revealed an increase in compressive strength from 500 psi to 1,638 psi within 24 hours at 260 °F. These results confirm that the combination of lead and tail slurry systems with the selected additive configuration delivers optimal cement performance in HTHP environments.
