Taranaki Basin - New Zealand - 2016

Nikau 3D GeoStreamer®

True broadband data acquired in the Taranaki Basin.
Website Map for Survey Nikau GeoStreamer MC3D
After building the first regional contiguous 3D seismic coverage in the Taranaki Basin, PGS have acquired new long offset GeoStreamer® MC3D data to provide superior seismic imaging and linking interpretation to the regional seismic coverage offered by Taranaki MegaSurvey.
Hydrocarbons are sourced from possible Jurassic to Miocene rocks with reservoir sands identified in the Upper Cretaceous to Pliocene sequences. Both structural and stratigraphic traps are pursued with the majority of exploration focused on structural highs.
True broadband Dual sensor 3D seismic data with pre-stack AVO/AVA fidelity.
