It has been widely accepted since the 1980s that Seram crude oils belong to one family that originated from the Triassic carbonate source rock. Even though these oils share similar nature and origin, they exhibit wide physio-chemical composition variations in Seram Basin. Moreover, this variation is also noted within a similar oil field. Hydrocarbo...

The Eocene interval of Central Sumatra Basin, the Kelesa Formation, has been well-known as prolific source rock within the basin. Most of the studies within the interval were focused on the source rock geochemistry. However, Kelesa Formation shale also provides good paleo-environmental records during the early rifting in Central Sumatra, in which t...

Seram Basin is a petroliferous basin in Eastern Indonesia with a complex geological setting. The crude oils in Seram Basin have been known to be originated from Triassic marine carbonate source rock that is composed by type II organic matter. However, carbonate rock could be divided into several organofacies that will expel crude oil with a distinc...
Conference Paper
Biomarker analyses can provide information about the source of organic matter, depositional environment, and maturity of source rock that is very useful for basin evaluation and understanding the petroleum system. In this paper, the study focuses on biomarker characterization of the Kelesa Formation that is situated in the Central Sumatra Basin, on...

This study was conducted in Kuang area, South Sumatra Basin, where three oil fields: Air Serdang, Mandala, and Kuang are situated. The Kuang area is surrounded by five sub basins (Cintamani, Jantung, Tanjung Miring, Meraksa, and Lematang). Talangakar Formation has been known as a source rock in the area, however the characteristics of the formation...

A common fallacy in evaluating shale gas potential in a basin is treating similar to those produced in the United States. In fact, each basin has unique characteristics that influence shale facies type and depositional. The Lower Baong shale is responsible for source rock in the sandstone reservoirs in the oil and gas fields in the North Sumatra Ba...

The most common fallacy in evaluating shale gas potential in a basin is treated similar to those produced in the United States. In fact, each basin has unique characteristics that influence shale facies type and depositional. Lower Baong shale is responsible for source rock filled up sandstones reservoir in the oil and gas field in the North Sumatr...

The Arafura Sea is situated in the eastern region of Indonesia. This region is tectonically unique since it has been formed by complicated interaction between three converging plates: the Eurasian and the Indo-Australian (continental) and the Pacific (oceanic). The tectonic around the area has been started during the early breakdown phase of the Au...
Article
Hydrocarbons (liquid and gas) seeps have been detected both onshore and offshore in the South Makassar Basin. The source rocks of the hydrocarbons has not been established yet. The most likely source rocks in the basin are the Paleogene (Eocene and Oligocene) sediments and, to some extent, the Neogene (Miocene) sediments. During this study, sedimen...

Petroleum System and Hydrocarbon Prospectivity of the Simenggaris Block and Its Surrounding Areas, Tarakan Basin, East Kalimantan, Indonesia: A New Approach by Using Sequence Stratigraphy. EXTENDED ABSTRACT Hydrocarbon exploration in the Tarakan Basin (Figure 1) has been started since more than fifty years ago. The discovery of Bunyu and Tarakan fi...
Conference Paper
Full-text available
Hydrocarbon exploration in the Tarakan Basin indicates that, in general, the eastern part (e.g. Tarakan and Bunyu fields) is more promising than the western area. In order to find more potential area(s), particularly in the western part, a new approach based on an integration study between stratigraphic framework and geochemistry has been conducted...
Article
Sediments and crude oils have been analysed using GC-MS techniques and shown to contain two homologous series of hopanes, namely 30-nor-17α(H)-hopanes and 25,30-bisnor-17α(H)-hopanes, as well as the common 17α(H)-hopanes.Homologues (C28 to C34) of the 30-nor-17α(H)-hopane series have been identified in crude oils associated with carbonate source ro...
Article
A suite of samples consisting of twenty-two crude oils and eight sedimentary rocks has been analysed for biological marker compounds by GC-MS. The sedimentary rocks are rich in carbonate minerals and the crude oils were reported to have been derived from carbonate source rocks. These samples are from a variety of geographical origins, geological ag...

We have measured the ratio 20S/(20S + 20R), the relative abundances of the 24-ethylcholestane diastereomers, in nine pairs of closely adjacent samples of coals and shales which represent a range of geological ages and different sedimentary basins. Within some sample pairs, the values were similar, in others they were very different. The differences...

Shale from Lahat and Talang Akar Formations were widely accepted by many geoscientists in Indonesia as general source rocks in Palembang sub-Basin which is part of South Sumatra Basin. The oil from Sopa Field was considered as hydrocarbon accumulation that had been migrated from local and regional deeps around Sopa Field, where Lahat and Talang Aka...
