Abstract

Formasi Baong Sub Cekungan Aru Cekungan Sumatra Utara. Pada tengah-tengah formasi terdapat lensa lensa batupasir halus serpihan. Formasi ini dinamakan Besitang River Sand dan Sembilan Sand, yang keduanya merupakan reservoir yang produktif dengan berumur Miosen Tengah hingga Atas. Bagian bawah formasi ini merupakan batuan sumber hidrokarbon yang bermigrasi akibat adanya struktur diapir. Penekanan batuan sedimen yang jenuh akan air kemudian menekan hidrokarbon dan terperangkap pada lapangan batupasir yang terdapat di tengah-tengah formasi. Tujuan dari penelitian ini untuk mengetahui kondisi geologi pada cekungan daerah penelitian, distribusi fasies dan pemodelan fasies. Dengan menggunakan metode bawah permukaan, yaitu metode mengumpulkan dan menganalisis data sekunder bawah permukaan. Penentuan fasies dilakukan dengan analisis elektrofasies, data log sumur, dan data seismik. Hasil akhir berupa kondisi geologi, persebaran fasies dan pemodelan fasies.

Abstract

Field X is one of the oil and gas production fields in the Jambi Sub-Basin. This study analyzes subsurface pore pressure using drilling and logging data. Subsurface zones generally have normal and abnormal zones. Abnormal zones are also called overpressure. Determining overpressure is important in the field of drilling hazards such as determining the weight of drilling mud. Determining overpressure is done to anticipate loss or kick. Accurate and appropriate analysis in determining overpressure makes well drilling operations in the oil and gas industry more efficient, safe and effective. In this study, there are three wells in field X with values of pore pressure of the BGS-1 well ranging from 338.6-3541 psi measured from 238 m SSTVD to a depth of 2489.91 m SSTVD. The value of the pore pressure of the BGS-2 well ranges from 403.8-3459 psi measured from 283.9 m to a depth of 1921 m SSTVD and the value of the pore pressure of the BGS-8 well ranges from 853-3455 psi measured from 600 m to a depth of 1783 m SSTVD. The overpressure mechanism in Field X occurs due to the loading mechanism or disequilibrium compaction. This is in accordance with the geological conditions of the Gumai formation which is in the transgression phase dominated by clay lithology causing an increase in pore pressure due to the inability of fluids to exit the rock during compaction.

Abstract

PT Baturona Adimulya operates an open pit mining system. Field conditions indicate variations in coal quality that influence the overall quality of the coal. This study aims to analyze the relationship between the coal depositional environment and the distribution of total sulfur content, as well as to assess the effect of calorific value on moisture content, ash content, and total sulfur. The study uses petrographic (maceral), ultimate and proximate analysis, as well as interpretation based on the Tissue Preservation Index (TPI) and Gelification Index (GI) methods. The results show that seams S and T are dominated by vitrinite macerals consisting of Telocolinite (Tc)

Abstract

IN THE 4.0 ERA, ALMOST EVERY ACTİVİTY RELATED TO THE EARTH REQUİRES İNTEGRATED AND SUSTAİNABLE GEOLOGİCAL DATA AND CONCEPTS. These activities include exploration and exploitation of geological resources. Earth Engineering students are led to be able to understand all types of rocks as the basis of earth science. Rock outcrops are clear and can be seen in real terms in the field. Therefore, the condition is quite far from campus, causing an effective learning media for prospective Bachelor of Earth Engineering students to recognize rocks. With the establishment of this Karang-Earth Park, it can be the right solution for this problem. The existence of this geopark miniature will later be taken from the rock outcrops in the Merangin-Jambi UNESCO Global Geopark Territory. This area was chosen for display rocks, because it is very complete of all types of rocks that are unique in terms of the age of the rocks, which were 323 Ma Carbon to Quaternary age.

Abstract

Geological mapping and structural lineament extraction in active volcanic terrains with rugged topography face major constraints due to dense vegetation cover and limited terrestrial accessibility. This study aims to evaluate and compare the spectral and spatial performance of multispectral remote sensing data for geological exploration through two main aspects comparative evaluation of the Normalized Difference Vegetation Index (NDVI) between Landsat 8 OLI (30 m) and Sentinel-2A (10 m), and application of Shortwave Infrared (SWIR) band composites of Landsat 8 OLI (Bands 5, 6, and 7) for automated structural lineament extraction. The methodology encompasses Top of Atmosphere (TOA) radiometric correction, NDVI transformation, RGB 5-6-7 composite processing, and automated lineament detection using the LINE algorithm in PCI Geomatica validated against DEM Hillshade. Results indicate that Sentinel-2A (10 m) excels in delineating micro-vegetation density and reducing mixed pixel effects in steep terrains. Conversely, Landsat 8 OLI is significantly superior and more efficient for regional geological exploration owing to its seamless single-scene coverage homogeneity and the heightened sensitivity of its SWIR channels (Bands 6 and 7) toward lithological texture variations beneath vegetation cover. The RGB 5-6-7 combination clearly highlights surface roughness contrasts (rough on structural hills and fine on alluvial plains) and successfully identifies 1,248 lineament segments with a dominant West–East (W – E) trend. This structural trend represents regional faulting and fracturing controlling the hydrothermal and hydrogeological systems of Mount Lawu.

Abstract

Hot springs are among the most common geothermal surface manifestations, typically emerging through fractures formed by tectonic processes. The subsurface structures associated with the Grao Sakti hot spring manifestation in Jangkat, Merangin Regency, were identified using GGMplus gravity data by analyzing rock density contrasts through cross-sectional interpretations of the First Horizontal Derivative and Second Vertical Derivative of the gravity anomaly data. The Complete Bouguer Anomaly map reveals several gravity anomalies ranging from 73.8 to 174.6 mGal, which are interpreted as the Masurai, Hulunilu, and Sumbing volcanic complexes, Dikit Fault Segment has promoted the development of a fault-bend basin within the study area and the Barisan Mountain Range. Structural interpretation based on the FHD and SVD maps indicates the gravity derivative results indicate that the Grao Sakti manifestation is associated with a subsurface structure interpreted as a normal fault. This interpretation is consistent with regional geological evidence, and previous studies conducted along the Grao Sakti hot spring profile that normal fault is interpreted to have developed as a consequence of the formation under a transtensional tectonic regime movement of the Dikit Fault Segment, a major segment of the Sumatran Fault System, which trends in a northwest–southeast direction.
