  • Undiscovered Petroleum Resources of Indonesia by John Kingston
    UNITED STATES DEPARTMENT OF THE INTERIOR GEOLOGICAL SURVEY Undiscovered Petroleum Resources of Indonesia by John Kingston Open-File Report 88-379 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards and stratigraphic nomenclature 1988 ASSESSMENT OF RECOVERABLE ENERGY RESOURCES The World Energy Resources Program of the U.S. Geological Survey (USGS) Intends to develop reliable and credible estimates of undiscovered recoverable petroleum resources throughout the world. Initial program efforts have focused on the major producing areas of the world to gain a broad geological understanding of the characteristics of petroleum occurrence for purposes of resource assessment, as well as for analysis of production potential. Investigations of production potential are carried out In cooperation with other U.S. Government agencies; specifically, the studies of the main free world exporting nations, of which this study Is a part, are carried out In cooperation with the Foreign Energy Supply Assessment Program of the Department of Energy. The estimates represent the views of a U.S. Geological Survey study team and should not be regarded as an official position of the U.S. Government. The program seeks to Investigate resource potential at the basin level, primarily through analogy with other petroleum regions, and does not necessarily require, therefore, current exploration Information that Is commonly held proprietary. In conducting the geological Investigations, we Intend to build a support base of publicly available data and regional geologic synthesis against which to measure the progress of exploration and thereby validate the assessment. Most of these Investigations will lead directly to quantitative resource assessments; resource assessment, like exploration, to be effective, must be an ongoing process taking advantage of changing Ideas and data availability the results produced being progress reports reflecting on a state of knowledge at a point In time.

The aromatic hydrocarbon fractions of Available online 5 November 2008 all coal samples were dominated by cadalene in the lower boiling point range and picene derivatives in the higher boiling point range of the gas chromatograms. Cadalene can be attributed to the contribution of Dipterocarpaceae and various hydrated picenes to the contribution of additional angiosperms to the coal forming vegetation. The picenes originate from alpha- and beta-amyrin.

  • NOTES This Article Intrinsically Interesting and Topical, with Talking
    NOTES This article intrinsically interesting and topical, with talking about one Indonesian archaeological issues that are important to the present, which is the root of the nation's diversity. The author tries to explore the diversity that since the beginning of the Holocene in Northern Sumatra in the regional context. However, there are some points that need attention or improvement revision, namely: 1. References: the author needs to update the bibliographycal references by citing the current publications regarding Neolithic of Indonesia and SEAsia in general. Since the third millennium quite a lot of new insights about past human migration in the scope of the Indonesia-East Asia. The missing actual references deviate the interpretation or statements, and on the other hand the obtained field data are forced to be applied in the old opinion. See for instance: Austronesian neolithic sites are claimed > 4000 BP in the western regions (Aceh), while the oldest date so far is ca. 4000 BP in Sulawesi, the first Austronesian arrival in Indonesian island from Taiwan-Philippines. 2. Understanding the regional Neolithic: It should be noted, at least there are two routes of neolithic migration to Indonesia. The one was by the Austro-asiatic speaking people from mainland Southeast Asia, and the other one was from Taiwan by the Austronesian-speaking people. The first one which is more plausible related to the sites studied is not mentioned by the author. In fact, viewing the old date of Takengon neolithic sites studied and the presence of the cultural markers of mainland Neolithic, the sites studied are probably related to that migration.
