Great South Basin - Canterbury Screening Report

Canterbury Great South Basin Screening thumb

GNS Science offer petroleum prospectivity screening reports for several basins in New Zealand. This report presents the geological setting and exploration history of the Canterbury and Great South basins, including an integrated assessment of new regional-scale seismic mapping with results from wells and regional geology. This 90 page report reviews the active petroleum systems in these two basins. Common risk segment maps are presented and petroleum prospectivity is assessed using multi-1D generation and ray-path migration basin models.

Included with the report is a GIS project that compiles all the available map data from the petroleum prospectivity evaluation of the Canterbury and Great South basins

To learn more about the reports, GIS maps and purchasing information please download the flyer below.

Great South Basin Regional Review

US$25,000;DVD

Great South Basin

This digital compilation presents the results of five years’ work by GNS specialists. All available data are synthesised into a basin-prospectivity study covering petroleum systems evaluation, well-failure analysis, oil- and source-rock analyses and a quantitative assessment of hydrocarbon generation.

Great South Basin: Well correlations and biostratigraphy

P. Schioler, 2008

NZ$ 25,000; DVD and hardcopy

Great South Basin Well correlations and Biostratigraphy

Review of the lithostratigraphy, biostratigraphy and paleoenvironmental setting of the Upper Cretaceous to Palaeogene succession. Revised correlations across the basin impact significantly on exploration potential.

This report reviews the lithostratigraphy, biostratigraphy and paleoenvironmental setting of the sediments of the Upper Cretaceous to Palaeogene, and presents new well correlation panels across the basin.

New interpretations include:

The top of the Hoiho Formation, which contains significant coaly source rocks, has been reinterpreted at new depths.
The age of the Kawau Sandstone Formation has been revised, and the formation may represent two discrete sandstone bodies.
The Wickliffe Formation has been informally subdivided into four units based on petrophysical log characteristics and biostratigraphy.
The Tartan Formation is shown to be equivalent to the Waipawa Black Shale Formation in the East Coast Basin. The Formation has been newly identified in wells, and the effect of erosion on the formation's distribution has been defined.
A new sandstone unit has been defined.

New Zealand Stratlink - Interactive Basin Chronostratigraphic Transects.

Boyes, A. F., et al. 2012

FREE in the New Zealand Petroleum Basin Explorer (PBE)

A digitally remastered, full colour version of the Folio 1: Cretaceous to recent Sedimentary Patterns in New Zealand. Each transect is provided as an individual PDF document, with built-in interactive links. The original chronostratigraphy in each basin has been updated to the New Zealand Geological Timescale 2010/1 with the use of Time Scale Creator software.

Within each transect there are also internal clickable links to measured sections, selected well summary sheets (displaying lithological and stratigraphic information with links to well header data), and brief formation descriptions (with external links to the New Zealand Stratigraphic lexicon).
