Orphan Basin - Canada - 2018

Tablelands 3D GeoStreamer

Positioned in the eastern part of Orphan Basin, the largest underexplored sub-basin of Grand Banks
Website Map for Survey Tablelands
This survey extends the footprint of 3D data north of the Long Range survey of the Grand Banks source fairway with 3D coverage of the eastern Orphan Basin.
There are potential producing reservoirs from Lower Cretaceous to Lower Tertiary above the Kimmeridgian source rock super highway. In conjunction with the Long Range survey to the south, Tablelands continues to identify play fairways north into the Orphan Basin.
Broadband imaging identifies all the necessary petroleum system elements contained in the highly underexplored Flemish Pass Basin and discoveries to the east.
