Subsurface Structure and Isopach Maps

Structural Cross Sections and Basin Physiography

Paleogeography and Prospectivity MapsThis suite of maps includes two-way time and depthconverted structure maps of four significant geologicalhorizons and isopach maps of intervening intervals coveringthe entire basin and are available as digital shape files.

This set contains 11 structural cross sections through theTaranaki Basin. The cross sections are derived from thestructure maps and are annotated with eight time-stratigraphic horizons tied from key wells. Four crosssections are palinspastically reconstructed allowing forpaleobathymetry and original sediment thickness, to depictbasin structure at the following times: end Cretaceous, endEocene, end Miocene. Also included is a sheet of smallscale maps illustrating basin morphology at different periodsin its evolution. The main structural elements in these mapsare cross referenced to the cross sections.

This set of maps presents the source and reservoir rockdistribution, and exploration potential of the majorchronostratigraphic intervals within the Taranaki Basin.Each map is supplemented with text, tables and figures,including example seismic reflection profiles and wirelinelogs, and key source rock and reservoir rock statistics. Thereare three sections.

ProductThe atlas is based on the examination and evaluation of a regional grid of seismic reflection data calibrated with biostratigraphic,well-log and lithological data from over 60 exploration wells distributed throughout the basin. The atlas comprises 50 1.1 x 0.8 mpaper sheets, featuring maps and cross sections at 1:500 000. Each sheet incorporates public information on one or moreparameters of the Taranaki petroleum system such as structure, source or reservoir.
