Abstract

North Papua Basin is a fore arc basin located in northern coastal of Papua Island. This basin filled by Middle-Upper Miocene turbidite sediment and overlied by Upper Miocene – Quarternary clastic sediment. Upper Miocene – Quaternary clastic sediments (Mamberamo Formation) composed by interbedding conglomerate, sandstone and shale as molasses deposit. A detailed stratigraphic study was performed to identify facies and its association of the Mamberamo Formation to that give a new perspective on the characteristics and development of facies succession of Lower Mamberamo Formation. Result  shows that the Lower Mamberamo Formation consists of three facies: A) cross bedding sandstone (subtidal), B) heterolothic silty shale (intra-tidal), C) carbonaceous shale (supra-tidal) deposited on Late Miocen to Plio-Pleistocene during centra range orogeny (syn-orogeny) as molasses deposits.Keywords: Fore arc basin, North Papua Basin, Mamberamo Formation, molasse deposits.

Abstract

Cisadane Watershed is one of the most rapidly growing areas and infrastructure development, and has developed as a residential, industrial, administrative centers and other economic activities. The purpose of this paper is to use remote sensing satellite imageries to identify the morphotectonic characteristics of the Cisadane watershed both qualitatively and quantitatively. Processing stereomodel, stereoplotting and stereocompilation on TerraSAR-X Digital Surface Model (DSM) and SPOT 6 imageries, produced the  Digital Terrain Model (DTM) image, which has not been affected by land cover. Fusion of the DTM  and Landsat 8 RGB 567+8 images  is used to interpret the distribution of lithology, geomorphological units, and lineaments, which are an indication of geological structures. The morphotectonic characteristics of sub-watersheds qualitatively was carried out a bifurcation ratio calculation (Rb) which indicates tectonic deformation. Based on the analysis of satellite images both qualitatively and quantitatively, the morphotectonic characteristics of the upstream, middle and downstream Cisadane Watershed have been deformed.Keywords : satellite images, morphotectonic, DSM, DTM, Cisadane Watershed.

Abstract

DOI:10.17014/ijog.9.2.219-228This paper focuses on the characteristics and distribution of shallow reservoir carbonate in an underground gas storage. This study was done on Parigi carbonate as a significant reservoir carbonate in West Java Basin. The carbonate is abundant, and it occurs at shallow depths 800 to 1000 m below sea level. This formation broadly spreads out in onshore and offshore West Java areas as platform and build-up carbonates. The development of buildup carbonates is mostly in a low relief offshore. They well-developed onshore where the build-up exhibits coral reef frameworks, high relief, reaching over 450 m in thickness. The carbonate outcrop in Palimanan, western Cirebon which has been studied is grouped into four types of lithofacies. The preservation condition of this carbonate reservoir is important, for the storage capacity can inject a big gas volume. The porosity and permeability parameters are the most influential factor in reservoir evaluation. The parameters for gas storage in this field are within the range of the existing field parameters in Europe and America.

Abstract

DOI:10.17014/ijog.9.3.291-302The methodology of facies analysis may include statistical examination to establish a local facies model. Without such examination, it is very difficult to predict the facies succession and to interpret the changes in depositional conditions from thick or complex stratigraphic sections. Based on the survey of sedimentary geologic literature in Indonesia, it is suggested that the aforementioned statistical method has relatively seldom been used in Indonesia. Such a situation may reflect a gap in information on the methodology and, accordingly, it seems imperative that there should be a re-exposition of the method. This paper presents a concise exposition of the combination of the embedded Markov Chain and binomial probability as one of the most successful statistical methods which are used in facies analysis. The results of previous studies of The Citalang Formation are used as a case study to illustrate its applications to the real geologic world.

Abstract

The research location is in the PPSDM Geominerba field campus. The campus is located in Padalarang, West Java that is surrounded by the open-pit mining of limestone and marble. This limestone was formed in Oligo-Miocene of Rajamandala Formation. The research objective was to determine the condition of the slopes around the campus based on geomechanical characteristics. Based on field observations, the slope angle in the area is dominated by steep slopes. The rock hardness level is dominated by hard rock with a hardness ranging from 50-100 MPa. Rock Mass Rating shows that the area is dominated by good rocks. While the Slope Mass Rating calculation show that the maximum slope angle is between 52-75°. Level of deformation and intensive weathering process will reduce the strength of the rock in the future. Several rock fall occurrences on this research area support this assumption. Yet, some local open pit mining area activity near the toe hill of the area need to be concerned regarding the effect of the local rock fall occurrences.

Abstract

Ponelo Island is located in the northern part of Sulawesi, which is still an enigma regarding the genesis of the volcanic rocks found on this island. Therefore, the objective of this study is to understand the petrogenesis and tectonic implication of these volcanic rocks. Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) to obtain trace and rare earth elements is the method of this study. The volcanic rocks found on Ponelo Island consist of basalt and basaltic andesite rocks with a calc-alkaline affinity. The transition data suggested a highly fractionated cause of low transition element (Ni=17-38 ppm; Cr=13-47) compared to primary magma concentration, anomalies negative of Ba, Sr, and Ti of spider diagrams, and negative anomaly of Eu (Eu/Eu*=0.88-0.99). Relationship between low concentration between Ce/Y (0.74-0.76) and La/Yb vs Sm/Yb ratio indicated ~5% spinel-lherzolite mantle source partial melting. On the other hand, incompatible element ratios, such as Ba/Nb (39.03-45.28), Ba/Th (75.52-82.67), Rb/Nb (3.93-6.22), K/Nb (1772.22-2703.45), Ba/La=13.67-14.57, Th/La (0.17-0.18), La/Nb (2.91-3.16), depleted Nb/U (6-6.74), and also lack of xenolith or enclaves indicate cryptic crustal contamination.  The slab-derived fluid indicated by ratios of Rb/Y (0/019-0/05), Nb/Y (0.10-0.11), Th/Yb (0.52-0.61), and Ba/La ratio (13.29-14.57). Ponelo volcanic rocks shows typical calc-alkaline island arc tectonic setting particularly with enrichment in ion lithophile element (LILE) and light rare earth elements (LREE) along with depletion in high field strenght elements (HFSE) and heavy rare earth elemets (HREE), as shown by spider diagrams.

Abstract

The presence of gas seepage born in Tanjungapi precisely in the southwestern part of the basin.This remission is supposed to be formed from main rocks of Mesozoic aged. The condition ofAmpana Basin formation cannot be separated from the effect of the relatively northeast-southeastsinistral strike-slip-fault. Based on the 43 outcrop, the main deformation product was identified asan extensional/hybrid joint with a relatively west-east fault line structure on average shear strain(η) = 58o (+) to (η) = 60o (+) and in form of the relatively northwest-southeast strike-slip-faultstructure line with the range of shear strains value between (η) = 45o (+) to (η) = 54o (+). Thekinematics movement of relatively vertical main stress gives a subsidence impact on the surfaceof Mesozoic-Paleogenic aged rock. The sedimentation process of Neogene-aged clastic, from theBongka Formation, Kingtom Formation, and Lonsio Formation ran fast and make the lowerMesozoic-Paleogene-aged rock being burdened by the upper younger rocks. The tectonicdevelopment in Ampana Basin is recorded in Lonsio Formation, Bongka Formation, and limestonein the form of structural indication and deformation showing the period of Central Miocene toHolocene tectonic with the relatively west-east direction of the main regional stress.

Abstract

AbstractThis paper emphasis the use of geological information gathered from surface mapping and subsurface data, the method that used was mainly utilizing statistical information and deterministic model interpreted. Comparison model was built to calculate the deviation between realization, the calculation was furthered can be used as a uncertainty to make a better decision to choose the best realization. Geostatistics is a branch of statistics focusing on spatial or spatiotemporal datasets. In geology, geostatistical is used for numerical calculation of subsurface approach with several data such as geophysical or geological observation. Geostatistics modelling have several parameters setup to obtain best approach model. The parameters namely lithological boundary, geological structure and random seed number. Process for modelling used 23 drilling data with various lithological type. Two type geostatistical method is applied for the data that is Indicator Kriging (IK) and Sequential Indicator Simulation (SIS) with grid size 1000x1000 and 2000x1500. Distribution of lithology begin without parameters. Resulted shown that the model not appropriate with geological surface data and mismatch lithology position. To obtained better model, several geological information is included before geostatistical calculation. From regional geology surface data is obtained geological formation within lithological information. Then, geological structure describes the geology fault and formation boundary.Keywords: Geostatistics, subsurface, enhanced model, variance, random seed number

Abstract

AbstractLinking geological analysis with petrophysical characterization in complex carbonate reservoir is a chalangging task. Many previous researcher has proofed that depositional facies in carbonate reservoir has very little advantages in reservoir quality due to overprinted with diagenetic facies. The difficulties in characterized the carbonate may rise because one does not include some genetic, geometrical and petrophysical character of the pore space, both geometry and distribution. The aim of this study is to evaluate the reservoir rock typing in carbonate reservoir by comparing rock-fabric descriptions analyzed in thin section with laboratory measurements of porosity, permeability, capillarity, and Archie m values. Methodology employed for this study involved the examination of thin sections and the integration of routine analysis data following lucia’s pore classification scheme. The first step in characterized the petrophysical class is the determination of interparticle porosity by substracting the separate vug porosity from total porosity. The separate vug porosity is estimated in petrographic analysis in 325 thin section samples. Than estimating the value for un cored interval by determining the relationships between total porosity, separate vug porosity and sonic interval transit time. The petrographic analysis to estimating the separate vug porosity is a qualitative way, and so the value is not quantitative, but the trend is still implies the value so the relationships between porosity and sonic log can be quantified. Calibration of pore types to acoustic log response is accomplished by making a detailed log of porosity types described from thin sections and constructing Z-plots of total porosity and transit time from logs and separate-vug porosity from thin sections . The “m” value (lithology exponent or cementation factor) is different from the other terms in the Archie equation in that it is related to rock fabrics, specifically to vuggy porosity. Reservoir characterization by using this scheme has proofed that geological analysis made in detailed thin section can be a helpfull tool since the validation in tested and produced interval shows a verry good relationships. Keywords : Reservoir Characterization, Baturaja Fm., Carbonate, Petrophysics.
