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 show the presence of active petroleum systems underneath the volcanic … Lanjutkan membaca Subvolcanic hydrocarbon prospectivity of Java

Seismic Atlas of SE Asian Basins

Hello world! I found a very interesting blog contains compilations of seismic images of geological features in Southeast Asia basins, mostly related to hydrocarbon potential in this region. Areas covered in this atlas: Indonesia, Malaysia, Brunei, Philippines, Thailand, and Vietnam. The quality of the seismic images are quite impressive. You can visit this blog that managed by two Indonesian geologist, Herman Darman and Minarwan here. Lanjutkan membaca Seismic Atlas of SE Asian Basins

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.

Neotectonics of the southern Sumatran Forearc

This article notes the structural features in the Mentawai forearc that can be interpreted as products of compression of the accretionary wedge and forearc basin sediments. Compressional phases since the Late Miocene initiated (a) the landward vergent foldthrust belt in the Mentawai Fault Zone (MFZ), (b) reactivation of seaward vergent imbricated thrusts in the retro-accretionary wedge, and (c) uplift of the accretionary wedge and some … Lanjutkan membaca Neotectonics of the southern Sumatran Forearc

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
