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

Satyana_2010_crust east

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.

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 about tectonics of Indonesia, and we want to share them with you. Enjoy our blog!

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

Maulin_2012
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 this area. Syn-rift play can be found in the western and eastern flank of JS-1 with Ngimbang Formation as the objective, whilst the post Kujung play can be emphasized on the flower structure pattern as an indication of wrench faulting. This wrench fault is responsible for tearing apart the Rancak and O.K. Formations during intra Miocene.
