Subvolcanic hydrocarbon prospectivity of Java

Numerous oil and gas seeps occur on Java Island concealing prospective basin sediments. However, most of this island is covered by volcanic products of Paleogene to Recent times. The volcaniclastic sediments buried the source rocks, burying the source rocks to depths of oil and gas windows. Oil and gas seeps in volcanic areas of Java […]

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 […]

Inverted intra arc transtensional deepwater basin in West – Central Java border: New interpretation of basin evolution and its implication to the petroleum system

This article, which has been presented AAPG Annual Conference and Exhibition, New Orleans, Louisiana, April 2010 explains about tectonics of a Tertiary deepwater intra‐arc basin that experienced inversion by thrust faults. Oil seeps along this area may indicate distribution of source rock. The expelled and migrated hydrocarbon could reach in to potential traps and accumulated in […]

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 […]

Discovery of outcrop-scale fine-grained sediment waves in the lower Halang Formation, an upper Miocene submarine-fan succession in West Java

This article is about the first discovery of outcrop-scale, fine-grained sediment waves in the left-side muddy overbank deposits relative to the down-current direction of the adjacent channel deposits in the lower Halang Formation turbidite system in a late Miocene back-arc basin, West Java. The present outcrop-scale examples can fill the gap in dimension and formative […]
