Article
Paleocene sandstones in the Kupe Field of Taranaki Basin, New Zealand, are subdivided into two diagenetic zones, an upper kaolinite–siderite (K-S) zone and a lower chlorite–smectite (Ch-Sm) zone. Petrographic observations show that the K-S zone has formed from diagenetic alteration of earlier-formed Ch-Sm sandstones, whereby biotite and chlorite–sm...
Article
Cretaceous sandstones of the Canterbury/Great South basins of New Zealand have locally undergone advanced diagenetic alteration, and this is likely to have had a significant impact on sand quality. However, data and samples are very scarce and little is known about the rock properties of these potential reservoirs. In this study we assess the degre...
Article
A geochemical and biostratigraphic approach has been applied to investigate the spatial and stratigraphic variability of Palaeogene sandstones from key wells in Taranaki Basin, New Zealand. Chronostratigraphic control is predominantly based on miospore zonation, while differences in the composition of Paleocene and Eocene sandstones are supported b...
Article
Eight latest Eocene to earliest Miocene stratigraphic surfaces have been identified in petroleum well data from the Taranaki Basin, New Zealand. These surfaces define seven regional sedimentary packages, of variable thickness and lithofacies, forming a mixed siliciclastic–carbonate system. The evolving tectonic setting, particularly the initial dev...
Article
A paucity of well data in frontier basins presents serious challenges for reservoir characterisation studies around the world. In this paper, we provide the first regional study addressing reservoir distribution, composition and quality in the frontier Canterbury Basin (CB) and Great South Basin (GSB) of New Zealand, and show how the results can be...
Article
Detailed petrographic analysis has been undertaken on Jurassic to earliest Cretaceous Murihiku rocks from Southland and South Auckland locations. They comprise lithic (primarily volcanic) and feldspathic (plagioclase-rich) sandstones that generally contain little detrital quartz, and classify as feldsarenites, lithic-feldsarenites, feldspathic lith...
Article
Mineralogical, geochemical and detrital zircon data from key reservoir intervals in Taranaki Basin are integrated with paleogeography and basement maps to provide a synthesis of changes in sediment provenance and sandstone composition through time. Results show that sandstone composition and quality in Taranaki is strongly related to sediment prove...
Article
Subsurface resources include oil, gas, coal, groundwater, saline aquifer minerals, and heat (for geothermal use). Pore space itself should also be considered as a resource as it can be used for injection of waste fluids, produced water, storage of natural gas, compressed air, and supercritical CO2. Use of subsurface resources can overlap in space,...
Article
The Kaimiro Formation is an early to middle Eocene, NE-SW trending reservoir fairway in Taranaki Basin, and comprises a range of coastal plain through to shallow marine facies. A time of regional transgression is observed across the Paleocene–Eocene transition, which is linked to a general global warming trend and to regional thermal relaxation-rel...

Screening of New Zealand's sedimentary basins indicates several gigatonnes of carbon dioxide storage capacity might be available. However, carbon dioxide storage is currently untested in New Zealand, and it is likely that most theoretical storage capacity will be discounted once detailed assessments are made.

Article
Clay-and lithic-rich sandstones are difficult to characterize through uncored well sections in terms of their grain size, porosity, and mineralogy, all of which are required for assessing reservoir quality and production performance. This paper presents results from a study through one such interval and shows how a combination of different techniqu...

The Pretty Hill Formation of the Otway Basin (Australia) has been studied as a natural analogue for geological storage of anthropogenic CO2 in order to examine the effects that CO2 concentration and reservoir heterogeneity have on CO2-related reactions. New petrographic data are presented, which validate the use of Hylogger™ as a tool to investigat...
Article
The Kapuni Field is the largest onshore petroleum field in New Zealand and produces CO2-rich, gas (c. 40–45 mol% CO2). Diagenesis within the reservoir is dominated by CO2-related reactions that have resulted in localised precipitation of kaolin (abundant), quartz, calcite, dolomite, and siderite, along with localised generation of secondary porosit...
Article
Many Cretaceous–Cenozoic coaly source rocks in Australasian and southeast Asian basins were deposited in coastal plain environments, yet the effect of early diagenetic marine influence on their oil potential is not well understood. An integrated organic geochemical and petrographic study of humic coals from the Eocene Mangahewa Formation (Taranaki...
Article
Full-text available
Middle to Upper Eocene strata in Taranaki Basin, New Zealand, consist of terrestrial, marginal marine, shallow marine and offshore sediments deposited in a series of transgressive and regressive cycles within a passive margin setting. Coastal plain facies are largely confined to eastern and southern sides of the basin and marine mudstones to wester...
Article
Late Cretaceous coals and coaly source rocks are the main source of hydrocarbons in the Taranaki Basin, yet to date there have not been any hydrocarbon discoveries within Cretaceous strata, and sandstone distribution and reservoir quality for this interval have been poorly understood. The Late Cretaceous sediments were deposited in several sub-basi...
Data
A core-based study of petrology and poroperm. This interactive illustrative guide and database provides a comprehensive summary of reservoir properties and quality, both geographically and stratigraphically, throughout the onshore and offshore areas of the Taranaki Basin. Reservoir degradation through burial, compaction and cementation is reviewed...

Preface. The Gorgon Project has the potential to be a very important project indeed, not only economically but also in terms of its application of new technology applied to decrease CO2 emissions at a scale that is unmatched anywhere else in the world. For this reason it is vital that we have a thorough due diligence process to evaluate the technic...

Article
Tight gas reservoirs have become popular targets in petroleum exploration in recent years, due largely to the increasing market demand for gas and also to technology advances used in extraction. Reservoir quality is typically poor due to deep-burial diagenesis, resulting in significant compaction, cementation, and illitization. However, analysis of...

An outcrop section of late Miocene deep‐water sediments of the Mount Messenger Formation in Taranaki, New Zealand, displays distinctive physical sedimentary features that allow differentiation of basin floor and slope fan depositional units. Sandstone grain‐size characteristics have been examined in this study to differentiate these two types of de...

The stratigraphy of the East Coast region comprises an Eocene mud blanket that might locally impede hydrocarbon flow between the Cretaceous-Paleocene source rocks and Neogene reservoir rocks. This study assesses reservoir potential of sandstones below the mud blanket, close to the source rocks. Also, as the margin lies on a Neogene transpressional...
Article
Oligocene sandstones of the Magazine Point Formation are exposed on the southernmost margin of the Taranaki Basin, at Nelson. The exposures provide some useful points of comparison and contrast for interpreting depositional elements of the producing Tariki Sandstone in peninsular Taranaki. The Magazine Point Formation is stratigraphically younger (...

Project
This project aims to support CO2 storage projects in Australian sedimentary basins through investigation of the controls on the formation of authigenic carbonates in low salinity, siliciclastic aquifers of the Great Artesian Basin (GAB) and other onshore sedimentary basins as natural analogues of mineralisation trapping in carbon geosequestration. We have also investigated high-CO2 coal seams that occur in many sedimentary basins including the Bowen-Gunnedah-Sydney Basin System in eastern Australia and provide natural analogues of the processes likely to occur as a result of CO2 injection and storage in coal systems. Our natural analogue studies in the Bowen and Gunnedah basins indicate that CO2 has been stored in coal and sandstone formations since the Mesozoic through a combination of adsorption and mineral carbonation reactions.
