Abstract

The Binuang area and its surroundings are genetically structural landforms which characterized by cuesta ridge line with curve lineaments pattern on northeast-southwest direction. Geomorphological approach were carried out to determine structural geometry of geological surface using qualitative and quantitative approach on multiple map analysis of remote sensing data. The result of quantitative analysis on elevation data are used to classify heights, slope shape and steepness, lineaments, drainage, and slope aspect. Optical images were classified to determine lithological pattern and boundaries through analysis of band ratios, decorrelation stretch, principal component, and spatial enhancement. The research area are classified into eight class of structural landforms, depicting deformations that occured in western flank of Meratus Mountains. The surface pattern indicates the influence of compressional stress, shown by fold belt with longitudinal characteristic and fault-bounded anticlines on northeast-southwest axis. The formation of main structure pattern on research area was compared with that on strike-slip fault analog model. The resulting correlation factor, R=0.932, shows that both of them are highly correlated. In conclusion, surface structure can possibly form another variation of thrusted mountain belt, such as thrust-dominated restraining bends.Keywords: landsat, SRTM, morphostructure, morphometry, rhomboidal pattern, Meratus.

Abstract

The fluvial to deltaic sediments of the onshore petroleum prolific of the Mahakam Delta in the East Kutai Sub-basin constrain organic rich sediments particularly within the Balikpapan Formation. This formation has been recognized as a source rocks of the conventional oil and gas production in the Kutai Basin. However, the geochemical studies to understand the origin of organic matter and paleo-environmental condition of this formation are still limited. A 390 selected samples of organic rich sediments from the Balikpapan Formation were analyzed by using organic petrographic and geochemical analyses. These analyses were used to define the sedimentary organic matter and moreover the paleo-environment conditions during deposition and their implication to the source rocks and hydrocarbon potential. The organic rich shales and mudstones of this sediment have high total organic content (TOC) values in range of 0.05% – 15.63% and coals are ranging from 2.25% to 57.11%. They are and mainly dominated by vitrinite maceral, with minor liptinite and inertinite. The minerals mostly consist of clay minerals, with minor pyrite and oxide minerals (quartz and carbonates). Rock Eval Pyrolisis analysis results show low hydrogen index (HI) values (4 to 248.52mgHC/g TOC) and predominance of vitrinite maceral reveal prevalence of terrestrially derived type III organic matter and their potential to generate gas. The max temperature values which is ranging from 411 to 435°C and Ro ranges 0.7% - 0.64% implies a low to moderate thermal maturation levels for an active source rocks. The organic matter accumulation is mainly associated with black shales and coals in the delta plain environment, derived from terrigenous organic matter.Keyword: Depositional environment, source rocks, Balikpapan  Formation, Kutai Basin.

Abstract

The Middle Baong Sand Formation has long been ascribed to the Malay Peninsula. However, this contradicts the results of chronostratigraphic correlation and rare earth element (REE) analysis, which indicate another source from the south. This research was conducted in North Sumatra, especially in Pertamina's onshore and offshore work areas. The comparison area is located in Kutacane-Karo and the Malay Peninsula. The objective of the study is to understand the provenance of the Middle Baong Sand Formation in North Sumatra. Data from four wells and 32 outcrops are used to evaluate the provenance and distribution of Middle Baong Sand in the study area. Besides that, secondary data from three outcrops are also used to support the analysis. The methods used in this study are chronostratigraphic correlation and REE analysis. The results showed that the provenance of the Middle Baong Sand onshore is estimated to originate from southwest Sumatra, contrary to general assumptions. Validation was carried out by comparing Malay Peninsula data with Kutacane research data and wells using REE analysis. The analysis results showed that the Middle Baong Sand Formation in the onshore area has a different provenance from the Middle Baong Sand Formation in the offshore area, which contradicts other research conducted so far. Based on this study, it is concluded that the paleogeography of the North Sumatra basin undergoes deepening symmetrically in the central basin since 10.46 million years ago (Mya).

Abstract

The Mahakam Delta is a strategic industrial area in East Kalimantan, Indonesia, in which oil and gas industries reduce ambient air quality and generate excessive noise. This research aimed to analyze the ambient air and noise pollution attributed to oil and gas production activities in the delta. Relevant parameters at five sampling points (UA-02 to UA-06) were measured and further analyzed in the laboratory, including total suspended particulate (TSP), SO2, Pb CO, NO2, O3, temperature, humidity, wind direction, wind speed, and noise. Indonesia’s air pollutant standard index (locally abbreviated as ISPU) with four parameters (CO, NO2, SO2, and O3) was used to determine the ambient air quality, and provisions written in the Decree of the Minister of Environment No. 50 Kep-48/MENLH/11/1996 were consulted for the noise quality assessment.  Results showed ISPU values in the range of 0–50 at the five sampling points, suggesting good ambient air quality and compliance with Government Regulation No. 22 of 2021. In addition, it was revealed that the noise parameter was lower than the upper threshold set in the Ministerial Decree, namely 65 dB. Nevertheless, monitoring air and noise quality at the main pollutant sources should be regulated through policies and implemented to protect the public from exposure to potential pollutants.

Abstract

The study was conducted in the South Sumatra Basin using geochemical data consisting of three exploration wells to determine geochemical characteristics such as richness, quality, maturity, and the depositional environment of the source rock. Additionally, the study delved into the one-dimensional burial history of the study area. Subsequent phases of the research involved the analysis of three crude oil samples and three rock extract samples. This analytical process encompassed the utilization of gas chromatography (GC) and gas chromatography - mass spectrometry (GC-MS) data. By scrutinizing the biomarker parameters extracted through GC and GC-MS, the research sought to discern the specific characteristics of the depositional environment for each sample and establish a correlation between the source rock and the crude oil. Based on source rock evaluation, the three source rock wells are potential source rock. Based on biomarker analysis, TAN-1 and TAN-2 have an oxic terrestrial/fluvio-deltaic characteristics with a dominantly higher plant contributions. Samples RA-12, RA-17, and RA-61 have a suboxic – anoxic fluvio-deltaic characteristics with contributions of dominantly marine algae. The oil samples taken from these wells have a negative correlation with the source rock samples. Maturity analysis of the TAN-1, TAN-2, and TAN-3 wells is still in its immature phase based on one-dimensional burial history modeling.

Abstract

Tephrostratigraphy is a study used in determining pyroclastics layers,especially those in Ash/Tephrograin-sized, that can be used as a correlational tool to find out the order of sedimentation from one volcanic eruption. Leles Sub-Basinal, Garut, is composed mainly by Quartenary Sediment on the toppest layer and Tertiary Sediment on the bottom (Sunardi,2014). These thing of Garut Basin located in a plateau which is surrounded by volcanic plateau and dominated by lake sediment, and geographically located at low latitudes (Sunardi,2016). Based on the existence of Leles Sub-Basinal which is located on active volcanic complex, followed by its pyroclatics sediments, it is very ideal for this area to be the object of Tephrostratigraphy  Study. Moreover, earlier study was never been done before thoroughly at LelesSub-Basinal area.Based on mineralogical study, the tephroof Leles Sub-Basinal divided to Crystal Tuf, Lithic Tuf,and Vitric Tuf (Schmidt,1981). The commonly found minerals are quartz, plagioclase, pyroxen, feldspar, and opaque.The emersion of other minerals, suchasolivin, amphibole, and biotite are not visible in general. Based on the presentastion of that main minerals, it was concluded that the tephrolocated in Leles Sub-Basinal came fromandesitic and basaltic magma types. While from granulometric analysis, tephro from Leles Sub-Basinal was grouped in coarse ash and fine ash with well sorting and fall deposits mechanism of sedimentation. This tephrocontains many heavy minerals with bulk density variated around 2850-2900 kg/m3, which consists of apatite, biotite, and hornblende. Those heavy minerals are commonly found in ash falls lithology (Gale & Hoare, 2011). Stratigraphically, there were two period so feruption happening at Leles Sub-Basinal area, with unidentified volcanic vents due to lack of data. It is also concluded that the supported station in the south has stratigraphical  relationship with keystation. Keywords: Tephro, Tephrostratigraphy, Tuf, Leles Sub-Basinal.

Abstract

Ophiolite outcrops offers a unique opportunity to learn directly oceanic lithosphere, as ophiolite represents one of the few outcrops of rock that body can not be reached. Ophiolite is interpreted in the context of plate tectonics, as part of the oceanic lithosphere thrust into the continent during the first phase of orogenesa. Many geologists believe that the definition of ophiolite according to Penrose Field Conference in 1972, which is a typical sequence of rocks composed of, starting from the bottom: the complex ultramafic, gabbro complex, complex sheeted mafic dikes, complex mafic-volcanic and sedimentary pelagos. Ophiolite sequence may be incomplete, torn or termetamorfisme. Group ophiolite in area Ciletuh is an assemblage of mafic rocks (basalt, gabbro and ultramafic (peridotite, serpentinite), which is closely associated with the sedimentary-volcanic and metamorphic rocks. Generally ofiolitnya a sequence ophiolite very incomplete, and the mechanism of the transferor-tempatannya (emplacement ) can be equated with ophiolite "Cordilleran", which is rather a ophiolite (ocean floor, which did not contain fragments of the continent) above the subduction complex.
