Geological overview of the Taranaki Basin Environmental science essay
The Taranaki Basin is located along the west coast of the North Island of New Zealand (Fig. 1). It is considered the most productive hydrocarbon province in New Zealand. This basin produced a million barrels of oil and. cubic feet of gas by the end, NZP amp M, 2014. The best known onshore fields in, The geological evolution of the Taranaki Basin has been studied by numerous researchers, most notably by Thrasher King and Thrasher Palmer and Geoff Palmer and Pilaar and Wakefield The general consensus describes that the formation of the Taranaki Basin began when Australia and Zealandia split, as a result of the. The reservoir quality of the Farewell Formation and F-Sand sandstones in the Taranaki Basin is mainly determined by variations in grain size and the presence of kaolinite. which is often cited as the major cause of reservoir quality decline in the Palaeocene Taranaki Basin Martin et al. 1994 Smale et al. 1999 Pollock, The palaeohistory of basin filling is illustrated on a series of sediment distribution maps for the major reservoir intervals in Taranaki, integrating results and interpretations with Tulloch et al.'s new basement geological map in preparation, based on Mortimer et al. 1997, tectonic reconstructions from King 2000, and paleoenvironmental maps from, article Jumat2018GeochemicalCD, title Geochemical features, depositional environment and hydrocarbon generation modeling of the Upper Cretaceous Pakawau Group in Taranaki Basin, New Zealand, author Nurhazwana Jumat and Mohamed Ragab Shalaby and Akm Eahsanul Haque and Aminul Islam and Lim Lee, a reservoir characterization study has been carried out, using petrophysical and petrographic analyses, on the Paleocene Farewell Formation in the Taranaki Basin, New Zealand, based on five selected wells. Farewell Formation is largely a sandstone formation of the Kapuni Group. The integrated study has shown that Farewell, mineralogical, geochemical and detrital zircon data from key reservoir intervals in the Taranaki Basin have been integrated with palaeogeography and basement maps to provide a synthesis of changes in sediment provenance and sandstone composition by over time. The results show that the composition and quality of sandstone in Taranaki is strongly related to. This study integrated three-dimensional 3D structural and petrophysical models to determine the reservoir characteristics of the Mangahewa Formation within the Pohokura gas condensate field. A long-standing problem in understanding deep-water turbidite reservoirs relates to how the three-dimensional evolution of deep-water channel systems evolves in response to channel filling on a spatiotemporal scale, and how depositional environments influence channel architecture D-structure and the temporal evolution of stratigraphic data of petroleum resources and seismic reflection analysis reveal two distinct episodes of subsidence in the southern New Caledonia Trench and the deepwater Taranaki Basin. Tectonic subsidence of 2. was related to Cretaceous rift faulting and post-rift thermal subsidence, and 1. to anomalous passive tectonic subsidence. Paleocene fluvial to marginal marine arkosic sandstone beds of the Farewell Formation are an important proven hydrocarbon reservoir in Taranaki Basin, New Zealand. The Paleocene sedimentary system grades northwards from fluvial deposits in the southern Taranaki Basin, including within the Manaia Graben, to the marginal sea . The Taranaki Basin is located along the west coast of New Zealand's North Island (Fig. 1). It.,
