North Madura 3D GeoStreamer

Revolutionize your understanding of the North Madura Platform and its associated grabens
Website Map for Survey North Madura Geostreamer MC3D
State-of-the-art recording and imaging techniques available in Indonesia for the first time offer new insights, revealing the proven and under-explored Ngimbang clastics, the distribution and geometry of grabens, basement definition, and imaging of high dips on faults that can act as seals.
There are numerous untested leads in Kujung Limestone. The deeper Ngimbang play is prevalent in the survey area, and there is also a potential basement play. The key to success is understanding the petroleum system.
GeoStreamer acquisition and imaging techniques, including SWIM, record more detailed broadband data from shallow to deep. These exploit a full spectrum of low-to-high frequencies to provide clearer images and more reliable data for AVO/AVA analysis.
