Crustal Structures of the Eastern Sundaland’s Rifts, Central Indonesia: Geophysical Constraints and Petroleum Implications

Halo! This is a note about a paper presented in International Geosciences Conference and Exposition in Bali almost 3 years ago. This paper highlights the origin of crustal structures of Eastern Sundaland. Based on evaluation of available seismic, gravity, and magnetic data, the author proposed tectonic interpretation of the areas and the implications for petroleum accumulation.

Tectonics, Stratigraphy and Geochemistry of the Makassar Straits: Recent Updates from Exploring Offshore West Sulawesi, Opportunities and Risks

This is a review paper on the tectonics, stratigraphy  and geochemistry of West Sulawesi Offshore, Indonesia. This paper is presented at the 36th IPA meeting. The increase of exploration activity in West Sulawesi Offshore has enhanced our understanding but, it cannot instantly build a thorough knowledge of the petroleum geology of the area. There have been surprising results, both positive and negative, that were unexpected … Lanjutkan membaca Tectonics, Stratigraphy and Geochemistry of the Makassar Straits: Recent Updates from Exploring Offshore West Sulawesi, Opportunities and Risks

Welcome to our blog

Hi all! Welcome to our blog, Tektonesiana. The name of Tektonesiana is derived from the word tectonics and Indonesia. Tektonesiana represents our ‘passion’ on tectonics of Indonesia. We, Indonesian geologists who share the same interest, use this blog to post articles that represent our works. These articles have been presented in scientific meetings. Some of them also have been published in journals. We have many questions … Lanjutkan membaca Welcome to our blog

Central Java, Indonesia – a “Terra Incognita” in Petroleum Exploration: New Considerations on the Tectonic Evolution and Petroleum Implications

This is a title of an article that has been presented at the IPA Annual Convention and Exhibition 2007. This article reviews the tectonics of Central Java Indonesia. This area shows a conspicuous re-entrant or indentation of its coastline compared to those of the western and eastern parts of Java Island. This indentation is considered to express wrench segmentation of two major Paleogene strike-slip faults … Lanjutkan membaca Central Java, Indonesia – a “Terra Incognita” in Petroleum Exploration: New Considerations on the Tectonic Evolution and Petroleum Implications

Structural Style and Evolution of the Sumatran Forearc Basins

The interesting point of this article, which has been presented at INDONESIAN PETROLEUM ASSOCIATION 35th Annual Convention and Exhibition May 2011 is that the deep seismic reflection data acquired by Western Geco and CGGVeritas have provide new information for understanding the evolution Sumatran forearc basins.

Structural Reactivation and its Implication on Exploration Play: Case Study of JS-1 Ridge

This work has been presented at INDONESIAN PETROLEUM ASSOCIATION, Thirty-Sixth Annual Convention & Exhibition, May 2012. The authors of this article explained paleotectonic evaluation of the WMO area, and suggests another potential play other than Kujung Formation. Seismic interpretation with some attributes and also ant-track method are applied to strengthen the exploration concept. Another play that is quite interesting should be added to exploration in … Lanjutkan membaca Structural Reactivation and its Implication on Exploration Play: Case Study of JS-1 Ridge

Structural evolution of backthrusting in the Mentawai Fault Zone, offshore Sumatran forearc

This article presents the interpretation of newly acquired high-quality industry-standard deep seismic reflection and swath bathymetry data to provide insight into the structural style and evolution of the Mentawai Fault Zone (MFZ). The structural style, lateral distribution and kinematics of the fault zone has been discussed related the development of forearc high thrusts and accretionary wedge mechanics. The implication of this fault zone to the … Lanjutkan membaca Structural evolution of backthrusting in the Mentawai Fault Zone, offshore Sumatran forearc
