Taranaki Basin - New Zealand - 2016
Taranaki MegaSurvey
PGS MegaSurveys provide an excellent opportunity to evaluate prospectivity on a regional basis.
We have built the first regional contiguous 3D seismic coverage in the Taranaki Basin. The Taranaki Basin is the only producing petroleum basin in New Zealand and the charge model is still poorly understood in part due to the lack of regional seismic coverage.
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.
Inversion and uplift in the Late Miocene complicates the charge model.
The MegaSurvey contains 11 360 sq. km of 3D seismic data matched and merged with 5 140 km of 2D data converted into depth from a seismic horizon constrained velocity model covering the New Zealand Taranaki Basin.
