West Timor 3D GeoStreamer

Unlocks the petroleum potential of the deep plays in West Timor with advanced imaging technology
Website Map for Survey West Timor MC3D
This MC3D survey offers a broader understanding of the area with better imaging of the deepest targets under the accretionary prism. Builds on proven fields with extension on both sides of the border.
The working petroleum system in the region is demonstrated by the abundance of oil and gas seeps. This high-quality seismic dataset offers unprecedented resolution from overburden to target level, including the deeper section.
Detailed GeoStreamer data from shallow to deep, acquired with good spatial sampling using a triple-source configuration with high-density cross-line recording. Advanced imaging techniques exploit low-to-high frequencies, providing clearer images and more reliable data for AVO/AVA analysis.
