Abstract

DOI: 10.17014/ijog.v7i2.139The research was carried out on the sediments of the Batuasih Formation cropping out at Batuasih Village, Cibatu River, Padaarang Sukabumi. Data obtained from field observation, as well as foraminifera and sedimentology analyses conducted in the laboratory, were used to interpret its depositional environment. The investigation was focused on planktonic and benthic foraminiferal assemblages for depositional environment interpretation that might not be used by previous researchers. The Batuasih Formation is composed of black shaly claystone, where the lower part is rich in clay ball, and limestone intercalations in the upper part of the formation. In Cibatu Section, no clay balls is recognized in the lower part, but intercalations of limestone still occur. However, a contrast difference is found in Padaarang section, where green claystone interbeds with fine-grained sandstone. The Batuasih Formation conformably overlies the Walat Formation containing conglomerate. Foraminifera fossil found in the Batuasih Formation consists of bad preserved black benthic and planktonic foraminifera, more abundant towards the lower part of formation. Based on foraminifera assemblage comprising genus Uvigerina, Cibicides, Elphidium, Operculina, Bulimina, Bolivina, Eponides, and Neoconorbina, supported by sedimentology data, the Batuasih Formation was deposited in a shallow to deep marine environtment, during Early Oligocene (P19) time. Upwards to be the Rajamandala Formation, the depositional environment tends to be shallower gradually.

Abstract

DOI: 10.17014/ijog.v6i1.112An understanding of deepwater turbidite sediments is very important mainly dealing with the determination of a reservoir geometry. The problem arising in the turbidite sediment geometry is very complex and varied, and its existence depends on how, when, and type of its environment. In Central Java, the broad turbidite sediment distribution of the Halang Formation is needed to be observed its facies association. This paper will discuss the turbidite facies of Halang Formation in the Ajibarang area. The method used to analyze the turbidite facies is by measuring stratigraphic sections and observing the lithofacies characteristics to reconstruct its depositional environment. The Halang Formation outcrop in the Ajibarang area is dominantly composed of alternating sandstone and claystone or marl. Based on the observation, the turbidite facies of Halang Formation, in the Ajibarang area, was deposited on a submarine fan system at the middle fan of suprafan lobes. Compiling with the previous studies, the source of the Halang Formation is indicated to be derived from the south southwest.

Abstract

http://dx.doi.org/10.17014/ijog.vol4no3.20092The purpose of the study carried out on the claystone of Batuasih Formation in Sukabumi area is to find out the hidrocarbon potential and its characteristics. The Batuasih Formation, overlying conform- ably the Walat Formation, consists  of claystone, dark gray, shaly, brittle, containing clay ball, calcite veins, with carbonate intercalations. The geochemical analysis conducted on twelve samples shows the TOC values vary between 0.49 – 1.14 % and Tmax of 431 – 434o C. Four samples are categorized to be immature, while the rests are mature. HI values of the Batuasih Formation varying from 77-191 mg HC/ TOC indicate that the samples are of C and CD organic facies. Based on those analyses, the source rock is favourably potential to generate a small quantity of hydrocarbon and gas. The hydrocarbon source rock potential level in the investigation area shows a poor to fair organic richness, and its kerogen is included into types II and III. The source rock quality based on the Hydrogen Index (HI) value tends to be a gas prone.

Abstract

Rock unit crops out surrounding the Cipluk oil field is part of the Kerek Formation according to the regional geological map, however, the stratigraphy, depositional environment and relative age of the rock unit is not clearly recognised. Detailed stratigraphic and micropaleontological studies have been done in the rock unit surrounding the Cipluk of  oil field. The results show that the rock outcrops in the study area are composed by a repetition of marl intercalated by sandstones,identified as turbiditic facies part of a channel portion of supra fan lobe to outer fan that deposited in an upper bathyal. Based on planktonic foraminifera content, the relative age of rockunit is Pliocene to Late Pleistocene. According to the litological characteristics and relative age data, the rock unit in studied area seems to be not part of the Kerek Formation, but it belongs to part of the Kalibeng Formation. The result of this study is very important for updating the surface geological data in which will be very useful to understand the new petroleum system in this area. Keywords: Kerek Formation, Cipluk oil field, turbidite, Kalibeng Formation

Abstract

The Campurdarat Formation is one of the carbonate rocks exposed in the Tulungagung areas and its surrounding, East Java. Detail investigation for studying facies and sedimentation of this limestone has been conducted. The investigation include field investigation and laboratory method, consisting of petrography and micropaleontology. The result of petrographic analysis showed that the carbonate rocks in the area investigation can be divided into four types of facies such as packstone, floatstone, rudstone and boundstone. Packstone facies was deposited from the backreef – lagoon environment, floatstone facies in backreef and coral zones environments, rudstone facies in the reef zone environment and boundstone facies formed starting from the reef front - reef crest. The Campurdarat carbonate rocks are interpreted to represent a barrier – reef of Early Miocene age.Key words : Campurdarat Formation , facies, carbonate, environment, sedimentation, reef, Tulungagung
