Abstract

The North Sumatra Basin (NSB) is located on the western part of Sundaland and covers approximately 60,000 km2 of onshore and offshore regions. With over 100 years of production, North Sumatra Basin is one of Indonesia’s most prolific sedimentary basins. As stated by Meckel (2012), 25 trillion cubic feet (TCF) of discovered gas reserves (equal to 4.5 billion barrels of oil equivalent, BBOE) and approximately 1.5 BBOE of oil and condensate reserves confirmed this basin as the third largest hydrocarbon-producing basin in Indonesia, after Central Sumatra and Kutei Basins, respectively.The first hydrocarbon discovery was Telaga Said Field in 1885. Since then, remarkable findings (e.g. Rantau, Arun, NSO A, Lhok Sukon A, etc) contributed to the considerable amount of oil and gas reserves. From 1985 onwards, drilling activity in the North Sumatra Basin was stagnant due to volatile geopolitical and geological condition in Aceh. A variety of underexplored plays still remain in the basin, especially from Paleogene and pre-Tertiary age.

Abstract

Palaeogeographic maps covering the southern and eastern sectors of the Banda forearc (Savu to the Kei islands, also including Timor and the Tanimbar islands) and adjacent parts of the northwest Australian continental margin are presented for the Early Permian, Middle-Late Permian, Early-Middle Triassic, Late Triassic, and Early, Middle and Late Jurassic. A series of palaeotectonic reconstructions from the Devonian to the mid-Tertiary show an interpretation of the sequential phases of rifting that dismembered northeastern Gondwanaland through this period. Three major phases of rifting are documented for the core region of the future Banda forearc, commencing in the Early Permian, Late Triassic and Middle/Late Jurassic. Each rift event is characterised palaeogeographically by high facies diversity, which is a consequence of strong differential vertical crustal movements at that time. The three rift phases are separated by two quieter tectonic intervals characterised palaeogeographically by low facies diversity (widespread development of marine shales) during phases of post-rift thermal subsidence.

Abstract

Sejak terbentuknya perhimpunan Ahli Geologi di Indonesia yaitu Ikatan Ahli Geologi Indonesia (IAGI) tahun 1960, maka semua ahli Indonesia yang tercakup dalam disiplin geologi telah berhimpun di dalamnya, meski sebenarnya dalam perhimpunan tersebut terdapat berbagai bidang keahlian khusus. Dalam perkembangan selanjutnya, pada tahun 1976 telah terbentuk pula sebuah perhimpunan yang menyatukan para ahli geologi yang bekerja dalam bidang geofisika ataupun bidang-bidang yang bukan geologi yang terkait seperti fisika dan lain-lain, dalam wadah Himpunan Ahli Geofisika Indonesia (HAGI). Dengan demikian, hanya dalam beberapa himpunan sajalah para ahli geologi dan geofisika berhimpun dan bersatu. Padahal, dalam disiplin geologi terdapat berbagai spesialisasi, termasuk sedimentologi.

Abstract

Jozef Zwierzycki was a Polish-German geologist with a very eventful life. This included a long and remarkably productive career with the Dienst van het Mijnwezen (Bureau of Mines/ Geological Survey of the Netherlands Indies) from 1914-1938, first as a field geologist and eventually as Head of the Geological Survey Department. This was followed by an eventful late career back in Poland during and after World War II.Zwierzycki left a legacy of about 50 scientific publications and a series of maps on the geology of the Netherlands Indies. In addition to his publications, he also authored many unpublished reports on surveys on gold, tin, petroleum and coal deposits in various parts of Indonesia.Jozef Zwierzycki was born on 12 March 1888 in Krobi (Kroben), which is now in western Poland, but until 1918 was under Prussian (German) control. He went to elementary school in Krobi and completed high school in Gnesen. From 1908 he studied natural sciences and geology in Leipzig, Munich and Berlin. He obtained a doctorate in geology in October 1913 from the Alexander von Humboldt University in Berlin, with a thesis on ammonites from the 1911-1913 Tendaguru Expedition to Tanganyika, East Africa. This was followed by study at the Bergakademie (Mining Academy) of Berlin, where he graduated as a mining engineer in early 1914.

Abstract

The Baram Delta, located in the NW Borneo, has long been recognized as prolific oil producing province in this region. The stratigraphic history of the Baram Delta has recently become a topic of many studies. The present day Baram Delta depositional processes have been widely used as an analogue to interpret the  ancient depositional framework of sedimentary successions in this area. As an aid to the reconstruction of the modern depositional model of the Baram system, this research project is initiated with two main goals.The primary objective of this research is to describe the distribution pattern and acoustic character of the Late Quaternary fluvial-deltaic-estuarine deposits preserved on the western Brunei Shelf. The approach adopted involves the use of high-resolution (Minigun, 2.5 kHz) seismic reflection data to map stratigraphic boundaries and to characterize seismic facies units bounded by these surfaces. Correlation of seismic horizons, mapping of faults and seismic units, and the generation of isochron and paleogeographic maps help to interpret the depositional processes and shelf evolution through the last eustatic cycle.The secondary objective of this research includes the study and evaluation of the evolution of the paleo-Baram coastline during the last highstand, with respect to the present rate of sediment discharge from the Baram River. The result so derived may assist us to better understand the depositional environment of the most recent Baram Delta sequences.

Abstract

A steep seamount with 320-350m of relief was recently discovered in about 2050m deep water of the South Makassar Straits. It was informally named Snorkel by ExxonMobil interpreters, but remains unnamed. Drop core samples collected from different levels of the buildup by ExxonMobil in 2008 show the Snorkel feature to be an Oligocene pinnacle reef, which drowned in latest Oligocene time.The carbonate buildup is covered in a thin coating of ferro-manganese cement, representing over 20 Million years of exposure and non-deposition in a deep water environment.The Snorkel feature is one of the many carbonate buildups that formed on Sundaland and around its margins after a Middle-Late Eocene regional rifting/subsidence event (e.g. 'Berai Limestone' of East Kalimantan), but until now is the only known example of an Oligocene reefal buildup that was never buried under younger sediments.

Abstract

Several major discoveries in the eastern part of Indonesia (e.g. Tangguh and Abadi) have increased more petroleum exploration interest in the area. These sizeable discoveries encountered gas in the Jurassic sandstone, which is a key reservoir target in the Northwest Shelf of Australia. The Mesozoic sandstone provenance is located in the Australian Continental Plate or also known as the Sahul Shelf. Thousands of wells were drilled in the Sahul Shelf and the stratigraphy in this area is well understood. The extension of the Mesozoic sandstone towards Indonesian territory, with much less well information, is one of the keys of success for petroleum exploration. Refinement of the stratigraphy of the eastern part of Indonesia is crucial to understand the extension.To refine the stratigraphy of Eastern Indonesia, especially for the Mesozoic interval, dinoflagellates play a significant role. Several types of this marine biota have been used by Australian stratigraphers as markers. In the case where stratigraphic tie to Northwest Shelf Australia discoveries, key wells or standard chronostratigraphy, dinoflagellate understanding is critical.Dinoflagellate markers are used to mark several subdivisions of Plover Sandstone. Norvick (2001) used W. indotata and D. caddaensis Maximum Flooding Surfaces to subdivide the reservoir target into upper, middle and lower Plover Formation. These surfaces are named after dinoflagellates. More markers were identified to mark the source rock and seal in the petroleum system. To have a detail correlation from Indonesia to the NW Shelf, understanding of dinoflagellates is crucial.

Abstract

Karimun-kundur islands are located in Riau archipelago as a part of a tin belt which extends from Myanmar in the north through Malaysia, Singkep, Bangka, and Belitung island in the southern end. The Karimun-kundur islands are also a part of granite island chain that emerged within the tin belt. The dating from the granite indicates Upper Triassic age and since then a lot of tectonic activities have taken place creating large variation of structural features which then influence the deposition of Quaternary tin deposit. The tectonism was intensively occurred in Pre-Tertiary time which was predominated by compression due to subduction processes. This structuring later control the younger structures within the study area.In Western Kundur (Lalang island area), there are some small granite islands that act as the sedimentary source rock. Structural reconstruction of the pattern of these islands show plausible structural orientation which is also aligned with the bathymetry. The water depth tends to be deeper in the northern portion which indicates that the Lalang island area was previously a paleo high in the past.Geophysical surveys had been undertaken within the study area, such as seismic reflection and magnetic. The seismic data quality was not satisfactory due to shallow surface condition, whereas the magnetic survey provided a better outcome. The most plausible interpretation of the magnetic dataset revealed that the basement was formed by granitoid and metasediments.

Abstract

The Lesser Sunda Islands or "Nusa Tenggara‟ as they are known in Indonesia, are a group of islands located to the immediate east of Java and to the north of Western Australia. Major islands in the group include Bali, Lombok, Sumbawa, Flores, Sumba and Timor. Most of the islands, except for Sumba and Timor, contain active volcanoes and are volcanic in origin. The volcanic islands are aligned in a W to E direction, forming the magmatic arc that constitutes the East Sunda-Banda Arc. Sumba and Timor are located to the south of the volcanic chain and they form the southern part of Banda Arc.The East Sunda Arc includes Bali, Lombok and Sumbawa. Flores, which is the next island located to the east of Sumbawa, is the beginning of the Banda Arc. The Banda Arc itself is subdivided into the volcanic inner Banda Arc that includes Flores, Alor, Wetar, and other smaller volcanic islands to the northeast of Wetar; and the non-volcanic outer Banda Arc that includes islands such as Sumba, Timor, Babar, Tanimbar and Kai. The boundary between the East Sunda and Banda Arcs coincides with a change in present-day relationship of Australia-Eurasia plates, from an oceanic subduction type to continental collision type. In the inner Banda Arc, no active volcanic activities currently exist in the Alor, Lirang and Wetar islands.This article summarizes the tectonic models of the Lesser Sunda Islands, particularly of the area between Java and the Timor islands. The summary is based on various publications of several key researchers, who have used their own findings and also those of other authors to propose their interpretation. The objective of this article is to review current understanding and interpretation of crust composition, tectonic models and arc volcanism of the region.
