North Madura 3D GeoStreamer

Revolutionize your understanding of the North Madura Platform and its associated grabens

State-of-the-art recording and imaging techniques reveal 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. They exploit a full spectrum of low-to-high frequencies to provide clearer images and more reliable data for AVO/AVA analysis.
