Abstract Tight gas reservoirs have become popular targets in petroleum exploration recent years, due largely to the increasing market demand for and also technology advances used extraction. Reservoir quality is typically poor deep-burial diagenesis, resulting significant compaction, cementation, illitization. However, analysis of tight using integrated techniques can improve our understanding about controls on reservoir quality, these results potentially be help predict at other sites. The...
Seasonal underground hydrogen storage (UHS) in porous media provides an as yet untested method for storing surplus renewable energy and balancing our demands. This study investigates the technical suitability UHS depleted hydrocarbon fields one deep aquifer site Taranaki Basin, Aotearoa New Zealand. Prospective sites are assessed using a decision tree approach, providing "fast-track" identifying potential sites, matrix approach ranking optimal sites. Based on expert elicitation, most...
Abstract Eight latest Eocene to earliest Miocene stratigraphic surfaces have been identified in petroleum well data from the Taranaki Basin, New Zealand. These define seven regional sedimentary packages, of variable thickness and lithofacies, forming a mixed siliciclastic–carbonate system. The evolving tectonic setting, particularly initial development Australian–Pacific convergent margin, controlled geographic, facies variability. This signal overprinted transgressive trend that culminated...
Clay- and lithic-rich sandstones are difficult to characterize through uncored well sections in terms of their grain size, porosity, mineralogy, all which required for assessing reservoir quality production performance. This paper presents results from a study one such interval shows how combination different techniques can be used better understand rock properties complex reservoirs, thereby helping reduce uncertainty. In this study, mean data laser grain-size analysis comparable...
Abstract An outcrop section of late Miocene deep‐water sediments the Mount Messenger Formation in Taranaki, New Zealand, displays distinctive physical sedimentary features that allow differentiation basin floor and slope fan depositional units. Sandstone grain‐size characteristics have been examined this study to differentiate these two types deposits. Outcrop data indicate sandstones are relatively sand rich comparison silt‐rich sandstones. Both show better sorting with increasing grain...
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 it can used for injection of waste fluids, produced water, storage natural compressed air, supercritical CO 2 . Use subsurface overlap in space, pressure changes at one site remotely influence use other sites. Resource vary time, such the depleted oil or gas fields storage. Before allocation is therefore useful to...
Summary Time-lapse seismic signatures can be used to quantify fluid saturation and pressure changes in a reservoir. This is why surveys are often acquired over fields where carbon dioxide injected for underground storage, or enhance oil recovery. In either scenario, the injection of CO2 acidifies water, which may dissolve and/or precipitate minerals. Understanding impact on rock frame from field time-lapse remains an outstanding challenge. Here, we study effects carbonate-CO2-water reactions...
Abstract A geochemical and biostratigraphic approach has been applied to investigate the spatial stratigraphic variability of Palaeogene sandstones from key wells in Taranaki Basin, New Zealand. Chronostratigraphic control is predominantly based on miospore zonation, while differences composition Paleocene Eocene are supported by evidence. Stratigraphic changes manifested a significant decrease Na 2 O across Zealand PM3b/MH1 early zonal boundary, at approximately 53.5 Ma. The change...
The Murchison and Maruia basins are situated on the Australian Plate adjacent Alpine Fault, an ideal place to study Cenozoic Australian–Pacific plate boundary evolution. Sandstone provenance was investigated using petrographic detrital zircon U–Pb geochronologic methods primarily varies geographically. Secondary up-section variation tracks spatiotemporal changes in basement exhumation. Eocene–middle Miocene western Basin sandstone is arkosic, derived locally from Devonian–mid-Cretaceous...
Detailed petrographic analysis has been undertaken on Jurassic to earliest Cretaceous Murihiku rocks from Southland and South Auckland locations. They comprise lithic (primarily volcanic) feldspathic (plagioclase-rich) sandstones that generally contain little detrital quartz, classify as feldsarenites, lithic-feldsarenites, litharenites litharenites. The oldest (Early Jurassic) are the most quartz-rich. Sandstones become more up-section, with very high volcanic contents occurring within...
ABSTRACT 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 K-S has formed from alteration earlier-formed Ch-Sm sandstones, whereby biotite have been altered to form kaolinite siderite, plagioclase reacted quartz. These zones can be difficult discriminate downhole bulk-rock geochemistry, which is largely due...
