Isochore_P00_P10
This grid depicts the interpreted vertical thickness (isochore) in metres between the P00 and P10 seismic horizons mapped within the Northwest Province of the Atlas of Petroleum Prospectivity (namely the Taranaki, Deepwater Taranaki, and Reinga-Northland basins). This isochore interval encompasses rocks of c. 66-56 Ma age (Paleocene). For more information about the seismic horizon naming scheme used in this project please refer to: Strogen, D.P.; King, P.R. 2014. A new Zealandia-wide seismic horizon naming scheme. Lower Hutt, NZ: GNS Science. GNS Science report 2014/34. 20 p. The TWT and depth grids, from which this grid was derived, were generated in Paradigm 2015 SeisEarth software using an adaptive fitting algorithm and a grid resolution of 1 km x 1 km. Faults have not been incorporated into the regional-scale gridding of the TWT or depth maps in this project. The TWT and depth grids were then exported from SeisEarth (Zmap format), checked for internal consistency in Zetaware (Trinity 4.61), edited as needed to account for gridding errors and then exported as ArcView Ascii grids. Given the considerable variability in the spacing and density of 2D seismic data over the entire NWP area the "smoothness" of the depth maps varies accordingly. In the central Taranaki Basin, where seismic line spacing may be 5 km or less, the 1 km x 1 km grid resolution captures the geological complexity well. However, in areas of the NWP such as the Deepwater Taranaki Basin to the west and Reinga Basin in the north, seismic line spacing may be in the order of 15 to 30 km. In such areas the underlying geological complexity is only captured where seismic interpretation exists along the available 2D seismic lines.

We acknowledge the many members of the APP and 4D Taranaki project teams, past and present, for their interpretations, comments, and inputs into developing these data. Previous GNS Science TWT mapping of the NWP has been incorporated into these data. This includes interpretation and reports by: Uruski et al. (2002, 2004, 2008); Stagpoole et al. (2009); Bland et al. (2014); GNS Science and NIWA (2014); and Bull et al. (2015). GNS Science thanks Paradigm Ltd, for use of seismic interpretation software (SeisEarth), and geological modelling software (SKUA-GOCAD), and Zetaware.com for use of Trinity software for grid QC. GNS Science also thanks the many companies that over many years have provided seismic data for use in research programmes such as APP, and also to the open-file petroleum data system administered by New Zealand Petroleum and Minerals. <br/><br/>This work programme is funded by the New Zealand Government, through the Ministry of Business, Innovation and Employment's (MBIE) Energy and Minerals targeted research fund. Contract C05X1406 to GNS Science. This work is also supported by the Petroleum Basins Research (PBR) and EEZ programmes via Direct Crown Funding from the New Zealand Government (MBIE). Compilation of these data was led by Dr Hannu Seebeck ( h.seebeck@gns.cri.nz ; seismic mapping) and Mr Paul Viskovic ( p.viskovic@gns.cri.nz ; gridding and depth conversion).
