North Sumatra - Andaman Sea - Indonesia - 2018

North Sumatra 3D GeoStreamer®

PGS is covering the Andaman basin with MC3D GeoStreamer
Website Map for Survey North Sumatra MC3D
This survey targets the central and western margin of the North Sumatra Basin, expanding understanding beyond existing discoveries and shelfal-related wells along the southern and eastern margin of the basin.
The current plays are Miocene carbonates, Miocene / Pliocene clastics and deeper Oligocene syn-rift, with a deeper, untested, syn-rift play and kitchen extension.
PGS GeoStreamer technology will provide resolution of structure at all depths, from overburden to target structures and basement, to provide a better understanding of the rift section and structural definition, and unlock the basement together with the kitchen distribution.
