Trinidad & Tobago - 2008

MCS DWECMA 2D GeoStreamer®

1,966 km of long-offset GeoStreamer® MC2D seismic data in Trinidad & Tobago deep Atlantic Area
Website Map for Survey MCS DWECMA
PGS’ TTDAA MC2D is designed as a regional grid focused on resolving deep structure and stratigraphy.
Robust Miocene to Pleistocene sedimentation derived from the Orinoco river system developed broad outer-neritic to mid-slope wedges of confined and sporadic sands that extend far into current deepwater areas.
