Indonesian Southern Margin 2D

Long-offset coverage of the Indonesian Southern Margin with cross border tie to Australia
Website Map for Survey Indonesia Southern Margin MC2D
The survey forms part of the greater PGS 2D long offset coverage of approximately 42 000 line km with continuous lines from Carnarvon in the SW through Browse/West Timor to Banda Arc/Timor Accretionary Prism in the NE.
The Seringapatam Basin is believed to comprise distal Early-Middle Jurassic shallow marine sandstones equivalent to Plover Formation, deep marine sandstones of Oxfordian age and potential Cretaceous sands and carbonates.
The survey was acquired with an 8km streamer and recorded to 12 secs.
