• Gravity and magnetic data

• New data released in 2012 (Deepwater Taranaki)

• Vintage data (tiff­ format) converted to segy

• New Zealand released petroleum wells

• DSDP wells

Offshore Taranaki Seismic Sequence Stratigraphy

Bland, K.J. & Strogen, D. P., 2012

FREE in the New Zealand Petroleum Basin Explorer (PBE)

This product presents sequence stratigraphic, and some seismic facies and structural interpretation on five composite seismic lines, using precursor regional-scale seismic horizon mapping undertaken by GNS Science. The seismic transects have been interpreted to illustrate the depositional and structural architecture of Taranaki Basin. Three NW–SE-trending “dip-lines” depict the sub-sea geology beneath the modern continental shelf and slope. Tying these dip-lines together are two broadly SW–NE-trending “strike-lines”, which roughly parallel the modern coastline.

All transects have been presented in three ways within a single Adobe PDF. Firstly, an un-interpreted panel is shown to provide a frame of reference for the following interpretations. The second panel depicts the interpreted distribution of a series of regionally extensive seismic horizons and the strata that they encapsulate. The third panel provides a generalised interpretation of sequence boundaries, channels, and packages of turbidites/basin-floor fans, mass transport deposits (MTDs) and progradational wedges. On some profiles volcanic edifices have been highlighted.

New Zealand Petrophysical Atlas, Taranaki

Lawrence, M.J.F., et al. 2012.

FREE in the New Zealand Petroleum Basin Explorer (PBE)

The work scope comprised wireline log evaluation of a number of exploration wells over petroleum basins in NZ to develop a consistent framework for assessing petrophysical parameters and rock properties of New Zealand reservoir and seal rock intervals. Work is focused on deriving standardised practices for the New Zealand setting which are detailed in the Methodology document.

Eleven Taranaki wells are included in this product, each containing well summary data, summary plots and standardised set of log curves and associated ASCII data.

CONOP (Constrained Optimisation) Correlation of the Taranaki Basin

Crampton, J., et al. 2012

FREE in the New Zealand Petroleum Basin Explorer (PBE)

This report presents the results of a quantitative stratigraphic analysis of 20 hydrocarbon exploration and appraisal wells distributed through the offshore Taranaki Basin. The analysis uses the method of constrained optimization (CONOP) to find the optimal order and spacing - the composite section - of an initial dataset comprising 1376 vetted and quality-checked biostratigraphic events (from 2829 paleontological samples), 18 seismic horizons, and 30 lithostratigraphic unit tops. The composite section has been age-calibrated using 50 approximately dated biostratigraphic events. It is used to derive high-resolution age-depth plots for each well and refined correlations between wells. The composite section, comprising 905 events, the projected positions of all events in all wells, and their modelled ages, are presented in digital form as a tool that can be used to answer specific questions relating to well correlation and dating.

Strogen. D., (compiler) 2011

GNS Science Data Series Number 005a,b
NZ$200 CD; ARC Reader (CD) format

As part of the facies characterisation objective of the 4D Taranaki (4DT) Project, a regional reassessment of the paleogeographic evolution of the Taranaki Basin and surrounding areas has produced a set of 31 maps spanning the Late Cretaceous to present day, which expand on those from previous studies and incorporates significant new data. These maps capture the most important aspects of the tectonic and sedimentary evolution of the Taranaki Basin, and form the basis for ongoing detailed paleofacies mapping and basin modelling studies.

FREE in the New Zealand Petroleum Basin Explorer (PBE)

Geochemical database

Five new geochemical databases covering the fingerprinting of oils, gases, gas condensates, oil shows and source rock extracts from the Taranaki and other New Zealand Basins, with an assessment of quality, maturity and genetic groupings. Each Database comprises a compilation of the results of a brad suite of analyses acquired under consistent analytical conditions.

Middle to Late Eocene Stratigraphy, Taranaki Basin, New Zealand

A catalogue integrating biostratigraphy, sedimentology, geochemistry & log data over the NW-SE trending Mangahewa Formation fairway
Higgs, K. et al. 2009.
FREE in the New Zealand Petroleum Basin Explorer (PBE)

Middle to Late Eocene

Most of the currently producing petroleum reserves in the Taranaki Basin are contained within a broadly NE-SW trending fairway of Paleocene- to Eocene-aged sandstones. This study is focused on better understanding the evolving depositional environment for the Middle to Late Eocene succession within the Taranaki Basin. Phase 1 of the study was completed in August 2006, which examined trends along a NW-SE oriented transect line (8 wells) cutting perpendicular to the interpreted paleoshoreline. Phase 2 was completed in 2010, the region investigated was extended to the north and south, with a total of 35 wells included in the study (27 new wells plus the 8 wells from phase 1).

The catalogue provides an interdisciplinary illustrative guide to the Mangahewa Formation. However, it is focused on developing a better stratigraphic and depositional model. An attempt has been made to correlate the Middle to Late Eocene deposits by integrating biostratigraphic ages and coal sulphur data (where available) with paleoenvironments from miospores, dinoflagellates and foraminifera, a sedimentological study of available cores, and wireline logs.
