Résumé :
The Java Island is an active volcanic arc that experiences several volcanism episodes, which gradually changes from South to North from the Late Oligocene to Pleistocene, following the subduction of the Australian plates underneath the Eurasian plates. During the Eocene, the southern and northern part of Java was connected as one passive margin system with the sediment supply mainly comes from Sundaland in the north. The compressional tectonics creates a flexural margin and a deep depression in the central axis of Java Island and acts as an ultimate deep-sea depocenter in the Neogene period. In contrast to the neighboring Northwest and Northeast Java Basins in the Northern edges of Java Island, the basin configuration in the East-West trending depression in median ranges of Java (from Bogor to Kendeng Troughs) are visually undetected by seismic due to the immense Quaternary volcanic eruption covers.Five focused window areas are selected for this study. A total of 1,893 Km sections, 584 rock samples, 1569 gravity and magnetic data, and 29 geochemical samples (rocks, oil, and gas samples) were acquired during the study. Geological fieldwork was focused on the stratigraphic unit composition and the observable features of deformation products from the outcrops. Due to the Paleogene deposit exposure scarcity in the Central-East Java area, the rock samples were also collected from the mud volcano ejected materials in the Sangiran Dome.The distinct subsurface configuration differences between Bogor and Kendeng Troughs are mainly in the tectonic basement involvement and the effect of the shortening on the formerly rift basin. Both Bogor and Kendeng Troughs are active petroleum systems that generate type II /III Kerogen typical of reduction zone organic material derived from transition to the shallow marine environment. The result suggests that these basins are secular from the neighboring basins with a native petroleum system specific to the palaeogeographical condition during the Paleogene to Neogene periods where the North Java systems (e.g., Northwest and Northeast Java Basin) was characterized by oxidized terrigenous type III Kerogen.

Résumé :
The Citarum River is an important river in West Java, which empties into the Java Sea carrying large suspended sediment concentrations. The purpose of this study is to examine the interaction of current patterns and distribution of total suspended solids (TSS) in the Northwest and Southeast Monsoons using hydrodynamic Modelling. The flow model and TSS used were 2-dimensional models with the OpenFlows FLOOD software. The ocean tide model results were validated using the Root Mean Square Error (RMSE) method with a value of 0.10. The current velocity in the West and East monsoons ranges from 0.07 - 0.35 m/s. Currents flow north and northeast during high-tide conditions and move south and southwest during low-tide conditions in both seasons. The movement of TSS was influenced by the current patterns. The highest concentration of TSS is in the Northwest Monsoon at low tide, which was in the range of 560–575 mg/L. The lowest TSS concentration was in the Southeast Monsoon during high tide conditions, ranging from 80 to 120 mg/L. The high concentration of TSS in the Northwest Monsoon was influenced by higher rainfall, with an average in January and only 23.2 mm/day while in the Southeast Monsoon it is only 7.8 mm/day.

Résumé :
A detailed analysis is performed of amplitude variation with angle (AVA) observations in six common‐midpoint gathers with reflection points that are over and beside carbonate reefs in the Parigi Formation in the northwest Java basin. Both empirical analysis and full‐wavefield modeling of the AVA data suggest that the presence of gas affects AVA by reducing the bulk density of the reservoir, decreasing of the overburden [Formula: see text] ratio and by local attenuation caused by gas sieving through the overlying sediments. The slopes of AVA curves for reflections from the top of the Parigi are negative for brine saturation and strongly positive for gas saturation.

Résumé :
DOI: 10.17014/ijog.v6i1.111Guntur Volcano in West Java is one of the most active volcanoes in Indonesia. The last eruption took place in 1847 and the volcanic activity has been dormant since then, however its seismicity is active. During the period of July to October 2009, the hypocenter distribution of VT earthquakes is mostly located at western flank of the volcano, beneath Guntur - Gandapura craters at the depth of less than 5 km. The depth pattern shows deeper to the northwest. The VT earthquakes deeper than 5 km were not found in this period. The focal mechanism of VT earthquakes are oblique normal fault, strike-slip fault and oblique reverse fault types. The mechanism of those earthquakes is not uniquely determined probably due to complicated structures at Guntur volcano complex area, which is aligned in NW-SE direction. T-axis of the oblique normal fault is trending in northwest - southeast direction similar to the structures found in the summit area of Gunung Guntur Volcano. Similarly, one of the strike-slip fault nodal line and P-axis of oblique reverse fault are also trending in northwest - southeast. Ploting of the earthquake source parameters (seismic moment, corner frequency, and stress drop) made to hypocenter distance shows no significant difference on those parameters between earthquakes at close and far distances to Kabuyutan station. It is probably due to the hypocenters are not concentrated in one zone. Meanwhile, the relationship between seismic moment (Mo) and seismic source radius (r) shows that for earthquakes with moment of smaller than 1018 dyne cm, the radius of the hypocenter is constant which is namely 60 m.

Résumé :
A detailed analysis and interpretation is performed of a 2‐D seismic line over a sequence of thin reservoirs in the upper Cibulakan formation in the Northwest Java Basin. Most well sites in this area are selected to be structures near fault zones as faults are assumed to be the main hydrocarbon migration paths. Amplitude variation with offset analysis is little used because of contamination by thin‐layer tuning effects. Attribute analysis, impedance inversion, and full‐wavefield modeling suggest that gas reservoirs are detectable even when they are less than their tuning thickness, as they correspond to acoustic impedance anomalies and low instantaneous frequency. The presence of hydrocarbons can also be detected by anomalous behavior in crossplots of acoustic impedance versus density and P‐wave velocity; sandstone reservoirs show low velocity and low impedance. Two‐dimensional P‐velocity and density distributions resulting from impedance inversion produce synthetic elastic common‐source gathers that display reflection behaviors that are qualitatively similar to the corresponding field data.

Résumé :
Java Island is an active volcanic arc that resides in the southwestern - southern boundary of Sundaland edges. The volcanic arc consists of several volcanism episodes, with a relatively younging trend northward (Late Oligocene to Pleistocene), following the Indo-Australian plates inward migration. In contrast to the prolific neighboring Northwest and Northeast Java Basins in the Northern edges of Java Island; the basin reconstruction and development in the East-West trending depression in median ranges of Java (from Bogor to Kendeng Troughs) are overlooked and lays bare the challenge to the seismic imaging due to the structural complexity of the overthrusted Neogene unit as well as immense Quaternary volcanic eruption covers. On the other hand, oil and gas seepages around the northern and central parts of the Island confirmed the active petroleum generation. Five focused window areas are selected for this study. A total of 1,893 Km sections, 584 rock samples, 1569 gravity, and magnetic data, and 29 geochemical samples (rocks, oil, and gas samples) were acquired during the study.

The result suggests that these basins are secular from the neighboring basins, The Northwest and Northeast Java Basins, characterized by oxidized terrigenous type III Kerogen. The contrasting subsurface configuration between Bogor and Kendeng Troughs mainly concerns the fold-thrust belt basement involvement and the tectonic shortening effect on the formerly rift basin.

Résumé :
The Northwest Java Basin is a mature oil and gas basin that has been explored and developed for more than 50 years. Almost all of the conventional plays have been explored and produced. Therefore, discovering new play concepts that potentially have significant resources are very challenging. A comparison of the Sunda, Ardjuna and Jatibarang Sub-Basins that are within the Offshore Northwest Java Basin was carried out based on the original plays of each sub-basin. The results led to the new play analogue for one sub-basin to another. The workflow for the study is as follows: data integration, basin statistics, basin modelling, basin comparison, play inventory, current original play type, play analogue and then play-based map. There are two potential new plays in the offshore Northwest Java Basin namely: (1) Eocene Carbonate Play and (2) Fractured Basement Play. The opportunities of these new plays at the new structure need to be further explored and accelerated to achieve the development phase, apart from the ‘old’ plays. The evaluation study of the Sunda Sub-Basin (including the Yani Sub-Basin and North Seribu Trough), Ardjuna Sub-Basin and Jatibarang Sub-Basin has revealed new exploration plays which are the Cretaceous Fractured Basement play, Eocene Carbonate play, Pre-Rift Volcanoclastic play, Early Oligocene Alluvial Fan and Lacustrine Sandstone plays, Late Oligocene Deltaic Sandstone play, and Miocene Shaly Sandstone play.

Résumé :
Abstract B-Field is located in Northwest Java and holds potential hydrocarbon in its low-quality marine sandstone reservoir, BR-34A and BR-34B zones. Each zone has a permeability range between 5 and 12 mD and can only produce approximately 20 to 50 BFPD without stimulation, making the well a non-economic producer. In 2020, two infill development wells, A-08 and K-08, were drilled targeting these zones. Both wells were planned to be completed with hydraulic fracturing stimulation to boost the production. The first well, A-08 was completed earlier than K-08, but the production result from the well was unsatisfactory. The pressure evaluation analysis indicated high near-wellbore pressure of more than 1,000 psi. There were no reliable mechanical properties data in the well, which led to a conservative final hydraulic fracture design to avoid fracture growth into the nearby watered-out zone, BR-35. Therefore, only 30,000 lbm of proppant were pumped, resulting in minimal proppant concentration in the pay interval for this reservoir of 360 lbm/ft even though the optimum amount of proppant for this type of reservoir is 1,000 lbm/ft. Limited proppant ramping concentration of only 6 PPA was also affecting proppant width around the wellbore, especially in this low Young's modulus reservoir. Because of this conservative design approach, the minimum target parameter from conductivity, dimensionless fracture conductivity, proppant concentration, does not meet optimum fracture half-length and skin. Eventually, the well could only produce 100 BFPD. A first application in the field of a comprehensive study of geomechanics using a sonic dipole log was performed to create a 1D mechanical earth model (MEM) on the second well, K-08, to validate the risk of breaking into the nearby water zone. In addition, this study was critical to confirm static rock properties and to revise the stress profile considering reservoir pressure change. As a result, it confirmed that the zones have enough competent shale barrier to hold the proppant volume according to the recommended design and that the zone has low Young's modulus (0.4 to 0.7 million psi) as well as lower stress compared to the preliminary estimation. A new technical approach then considered these additional facts to determine that a smaller proppant size with a larger amount of proppant would be optimal for maintaining width integrity and reducing the embedment effect. By using pressure evaluation software on the second well, better permeability and with less near-wellbore friction pressure were achieved. Later, a pressure match simulation analysis with optimum pad volume, larger volume of proppant, and higher proppant concentration resulted in a contained fracture in the zone of interest that did not break through the barrier into the watered-out BR-35 zone. Hence, the second well (K-08) has improved production performance with the well able to deliver over 500 BFPD.
