Abstract

Asri Basin is one of Indonesia’s sedimentary basins, and it is the carbon dioxide storage target in Carbon Capture Storage (CCS) technology. A study of carbon dioxide storage containers must be carried out based on geological aspects, namely geological and rock conditions. This research aims to identify reservoir feasibility values in the Asri Basin, such as pore pressure and fracture pressure, along with other factors affecting reservoir stability, in order to minimize leakage during the carbon dioxide injection process. The identification process in this research uses quantitative and qualitative studies based on well data. Eaton's method was used to estimate the research well pore pressure and fracture pressure in the research wells. The research well is located in the crestal area of the Asri Basin and has a pore pressure with a normal pressure trend. The fracture pressure value gets smaller in the depth range of the Talang Akar Formation. There is a process of diagenesis of the clay mineral smectite into illite, which begins to be found at a depth of 3000 - 3500 ftTVDSS. The developed stress regime is a normal stress regime with the vertical stress value as the largest. The injection process in the Asri Basin can be carried out in the Talang Akar Formation with several five storage intervals at a depth of 3560 - 4130 ftTVDSS.

Abstract

This study examines the relationship between facies and stylolitization in the Upper Araej Member carbonates of onshore Abu Dhabi. Analysis of core and thin sections identified four facies: wispy-laminated skeletal wackestone (F-1), peloidal skeletal mud-dominated packstone (F-2), coated-grain skeletal grainstone (F-3), and peloidal skeletal floatstone (F-4), deposited across a shallow carbonate ramp. Stylolites were described and measured for vertical offset amplitude to assess facies dependence. Results show facies-related tendencies in stylolite amplitude and morphology. Mud-supported facies (especially floatstones and wackestones) tend to display higher variability, with floatstones reaching amplitudes of up to 20 mm, whereas grainstones may also contain isolated high-amplitude stylolites (up to 14 mm). Packstones and wackestones, by contrast, rarely exceed 10-13 mm. Boxplots highlight greater variability in mud-rich facies, whereas grainstones exhibit narrower distributions. Statistical testing (ANOVA, p = 0.109; Kruskal–Wallis, H = 3.38, p = 0.34) indicates no statistically significant differences in mean stylolite amplitude across facies, although descriptive data reveal trends in variability and extremity. Jagged stylolites occur in both mud-rich and grain-supported facies, whereas wispy seams are strongly associated with micrite-rich facies and are largely absent in grainstones. Stylolites in these carbonates may act as both vertical barriers and localized porosity enhancers. Their facies-associated occurrence emphasizes the need to integrate stylolitization into reservoir models to better predict connectivity, compartmentalization, and flow behavior in Middle Jurassic carbonates.

Abstract

The Miocene Minahaki Formation in the Banggai Basin represented a key hydrocarbon reservoir, but its pronounced heterogeneity posed a challenge for field development. This study aimed to characterize the formation's carbonate facies and reconstruct its depositional environment in the “DM” field to establish a predictive model for reservoir distribution. The research employed an integrated subsurface analysis of core, cuttings, and wireline log data from seven wells. Four principal lithofacies (Bioclastic Coralline Floatstone, Dolomitic Algae Bioclastic Packstone, Argillaceous Dolomitic Foraminifers Bioclastic Wackestone, and Bioclastic Wackestone) were identified and subsequently grouped into two distinct facies associations: a high-energy Reef Margin Complex (FA-1) and a lower-energy Fore-Reef Slope (FA-2). Spatial correlation of these associations revealed a clear proximal-to-distal environmental gradient from west to east. The depositional architecture of the Minahaki Formation in the study area was interpreted as a rimmed carbonate platform. This model accounts for the observed reservoir heterogeneity, concluding that higher-quality reservoir bodies, characterized by moldic, vuggy, and intercrystalline porosity, are concentrated within the single reefal buildup that defines the western margin of the field. This finding provides a direct, geology-based predictive tool for optimizing future drilling activities and serves as a useful analogue for similar carbonate systems elsewhere.

Abstract

Karakteristik batubara dari dua wilayah prospek batubara di Sumatera dievaluasi dengan menggunakan metode kimia dan petrografi batubara. Penelitian terfokus pada evaluasi peringkat (tingkat pembatubaraan di daerah penelitian), tipe (komposisi material organik dan lingkungan pengendapan batubara) serta grade (kandungan material inorganik yang bisa berpengaruh terhadap proses utilisasi) batubara. Lapangan X memiliki lapisan batubara yang merupakan bagian dari Formasi Muaraenim dan Kasai Cekungan Sumatera Selatan sedangkan batubara pada lapangan Y merupakan bagian dari Formasi Petani Cekungan Sumatera Tengah. Sebanyak enam conto batubara dari lapangan X dan 8 conto dari lapangan Y digunakan dalam penelitian ini. Hasil penelitian menunjukkan bahwa kedua lapangan memiliki batubara dengan karakteristik yang berbeda. Walaupun batubara di kedua daerah termasuk dalam kategori lignit, nilai rata-rata reflektansi huminit batubara Lapangan Y sedikit lebih tinggi dari lapangan X. Hal ini mengindikasikan bahwa batubara lapangan Y mengalami pengaruh peningkatan termperatur dan pembebanan yang lebih tinggi dari lapangan X. Berdasarkan hasil analisis komposisi maseral, batubara lapangan X dapat dibedakan ke dalam 3 fasies: fasies 1 (huminit >90%, kandungan inertinit dan liptinit <10%), fasies II (huminit 80% s.d. 90%, inertinite 10% s.d. 15%, dan liptinit 10%) serta fasies III (huminit 75% s.d. 85%, inertinit 15% s.d. 20% dan liptinit <10%). Sementara batubara lapangan Y lebih homogen dan dapat digolongkan ke dalam satu fasies (huminit >90% dan liptinit serta inertinite <10%). Hasil plot Gelification index (GI) dan Tissue preservation index (TPI) menunjukkan bahwa batubara lapangan X diendapkan pada lingkungan limnic-marsh hingga limno telmatic sedangkan batubara lapangan Y pada lingkungan limnic hingga telmatic marsh. Banyaknya konkresi pirit pada batubara lapangan Y mengindikasikan bahwa batubara tersebut mendapat pengaruh laut yang lebih besar daripada batubara lapangan X Batubara di kedua lapangan dapat dianggap sebagai batubara grade tinggi atau batubara bersih karena memiliki kandungan sulfur (<10%) dan abu yang relatif rendah (<10%). Hanya satu conto (SJ2) yang memiliki kadar abu tinggi (>50%) menunjukkan bahwa conto tersebut bukan batubara. Sebagai kesimpulan, perbedaan karakteristik batubara lapangan X dan Y mendukung teori bahwa batubara dengan sejarah pengendapan yang berbeda akan menghasilkan karakteristik yang berbeda.

Abstract

Coal quality is one of the key factors in determining the effectiveness of processing and utilization. Coal quality assessment involves analyzing physical and chemical aspects to determine its characteristics. Coal quality is also influenced by geological conditions at the mining site, which affect the quality and amount of carbon in the coal. To ensure consistency, it is necessary to implement coal quality control based on physical and chemical parameters from the mining process in the pit to storage in the stockpile. Analysis of the effect of total moisture and ash on the calorific value of coal is the purpose of this study. The method used is a ROM (Run of Mine) coal sample located at the stockpile location. The relationship between Total Moisture and the calorific value of coal shows a negative linear correlation where the influence value for a 1% increase in Total Moisture is -71.343 kcal/kg and so is between Ash and the calorific value of coal 1% increase in Ash is -82.588 kcal/kg, which shows a negative linear correlation. Total Moisture increases by 1%, reducing the calorific value of coal by 71 kcal/kg, and increasing Ash content by 1% reduces the calorific value of coal by 83 kcal/kg.

Abstract

The Nanggulan Formation in Kulon Progo, Yogyakarta, Indonesia, is rich in ichnofossils as observed in a cross-section of the Watupuru River. This research aims to explore the relationship between ichnogenera, their behaviours and patterns during the deposition of the Nanggulan Formation in the Middle to Upper Eocene period. The study involved analyzing measured sections along the Watupuru River, paleocurrent measurements, and palynology. Seventeen ichnogenera were identified and linked to seven depositional facies within the Nanggulan Formation, i.e. Nummulites bank, prodelta, strand plain, delta front, delta plain, sandflat, and fluvial sand, categorized into autochthonous and allochthonous rock units. Allochthonous rocks, like tempestite and turbidite, were discovered within the autochthonous Nanggulan Formation with ichnogenera present in both types of rocks. Ichnofossils associated with the prodelta facies in autochthonous rocks included into Bergaueria, Siphonichnus, Phycodes, Trypanites, Treptichnus, Teredolites, Chondrites, and Thalassinoides, tend to indicate a muddy suspension environment. In contrast, the delta plain facies (FDP) indicating a calm oxidizing environment with ichnogenera contents like Teredolithes, Bergaueria, Scoyenia, Aulichnitus, Helminthopsis, Chondrites, Gastrochaelites, Ophiomorpha, and Siphonichnus were recognized. Factors influencing ichnofossil diversity include lighting, behaviour or adaptation to the environment, sedimentation rate, current control, and burrow infilling. The diversity of ichnofossils in allochthonous tempestite layers was influenced by post-catastrophic storm events. Barren ichnogenera at the base of tempestite layers indicated early storm surges, while the upper layers contained diverse ichnogenera such as Gastrochaelites, Psilonichnus, Bergaueria, and Planolites in the delta front facies (FDF). Tempestite layers in the sandflat facies (FSF) containing ichnogenera such as Thalassinoides, Bergaueria, Rhizocoralleum, Planolites, Cylindrichnus, and Siphonichnus, tend to show a favorable environment for organism post-storm.

Abstract

The composition of storm deposit layers (tempestites) is described as a normal sedimentary deposit or fining upward-deposit, divided into 3 units: the lower part, the middle part, and the upper part. The lower part is characterized by coarse clastics, the middle part known as T2 consists of a combination of hummocky and swalley layers containing finer clastics with good sorting. The upper part shows deposition of layering in increasingly calm current conditions with fine clastics: clay. The T2 interval is often considered a characteristic of turbidite deposit models due to gravity flow. However, on the other hand, the nature of storm-induced currents (hummocky-swalley) is more varied due to the role of 3 controlling currents: oscillatory currents, bottom currents, and combined currents. This study will investigate the characteristics of storm interval T2 (tempestites) in the Nanggulan Formation. The method applied is to generate stratigraphic sections for 3 sections (Kali Clumprit, Watupuru, and Songgo), age correlation and of paleocurrents analysis. Storm deposits are found in the Middle Eocene-aged Nanggulan Formation, showing a polymodal direction with opposing and branching within T2 interval. This pattern reflects two opposing directions: bottom currents and storm oscillatory currents. On the other hand, a combination current emerges, branching off from the main current pattern. The T2 Watupuru layer consists of overlapping hummocky layers that extend in a northwestward direction, indicating an ancient coastal or land area.

Abstract

ABSTRAK Kawasan panas bumi Gunung Ungaran, Jawa Tengah, menampilkan berbagai manifestasi hidrotermal seperti mata air panas Gedongsongo, Nglimut, dan Diwak yang memiliki potensi tinggi untuk pemanfaatan langsung (direct use). Penelitian ini mengkaji karakteristik geokimia air panas bumi serta potensinya sebagai media terapi kesehatan masyarakat berbasis geoheritage. Analisis lapangan dan laboratorium menunjukkan bahwa air panas Ungaran tergolong tipe Na–HCO₃ dengan kandungan dominan SiO₂, Ca²⁺, Mg²⁺, dan HCO₃⁻, pH netral hingga sedikit basa, serta suhu berkisar 38–45°C. Komposisi tersebut berperan penting dalam proses regenerasi kulit, relaksasi otot, dan peningkatan sirkulasi darah, sehingga mendukung fungsi terapeutik alami. Selain temuan ilmiah, penelitian ini juga menyoroti keberadaan situs Candi Derekan sebagai bukti arkeogeologis pemanfaatan air panas sejak masa kerajaan kuno, yang memperkuat nilai geoheritage dan geo-culture kawasan Gunung Ungaran. Dengan demikian, sistem panas bumi Ungaran tidak hanya signifikan sebagai sumber energi, tetapi juga sebagai aset geoheritage berorientasi kesehatan masyarakat, yang merepresentasikan integrasi antara geosains, budaya, dan kesejahteraan komunitas lokal. Pemanfaatan berbasis masyarakat ini berpotensi dikembangkan menjadi geowisata kesehatan berkelanjutan, sekaligus memperkuat upaya konservasi sumber daya panas bumi sebagai bagian dari warisan geologi nasional.
