Taranaki Basin
The Taranaki Basin is an onshore-offshore Cretaceous rift basin on the West Coast of New Zealand. Development of rifting was the result of extensional stresses during the breakup of Gondwanaland. The basin later underwent fore-arc and intra-arc basin development, due to the subduction of the Pacific Plate under the Australian Plate at the Hikurangi Subduction System. The basin covers approximately 100,000 km2 of which the majority is offshore. The basin contains mostly marine sediment, with significant terrestrial sediment from the Late Cretaceous to the Eocene. The majority of New Zealand's oil and gas production occurs within the basin, with over 400 wells and approximately 20 oil and gas fields being drilled. Overview The Taranaki Basin lies on the West coast of the North Island of New Zealand in the Taranaki Region, and is approximately 400 km west of the current Pacific-Australian plate boundary. It covers approximately 100,000 km2 and contains up to 9 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Ear ...

Zealandia (continent)
Zealandia (pronounced ), also known as ( Māori) or Tasmantis, is an almost entirely submerged mass of continental crust that subsided after breaking away from Gondwanaland 83–79 million years ago.Gurnis, M., Hall, C.E., and Lavier, L.L., 2004, Evolving force balance during incipient subduction: Geochemistry, Geophysics, Geosystems, v. 5, Q07001, https://doi.org/10.01029/02003GC000681 It has been described variously as a submerged continent, a continental fragment (or microcontinent), and a continent. The name and concept for Zealandia was proposed by Bruce Luyendyk in 1995, and satellite imagery shows it to be almost the size of Australia. A 2021 study suggests Zealandia is 1 billion years old, about twice as old as geologists previously thought. By approximately 23 million years ago the landmass may have been completely submerged. Today, most of the landmass (94%) remains submerged beneath the Pacific Ocean. New Zealand is the largest part of Zealandia that is above s ...

Geology Of Taranaki
The Taranaki Region of New Zealand is built upon the Median Batholith in the West, and Greywacke Rocks in the East. However, no rocks older than Miocene times are visible at the surface. The dominant feature of the Taranaki Region is the andesitic stratovolcano of Mount Taranaki, which is only about 130,000 years old. The dissected hill country to the East of the Taranaki Peninsula, and West of the Central Volcanic Plateau ( Ruapehu and Tongariro) is composed of soft Miocene to Pleistocene sandstone and mudstone. The coastal lowlands around Wanganui to the South have well-developed Quaternary marine terraces, and coastal sand dunes. The Taranaki Basin is the only area in New Zealand with significant known oil and gas deposits, many of them offshore. Basement rocks Basement rocks do not outcrop in the Taranaki Region due to the thick sedimentary and volcanic cover. However, the basement rocks have been inferred through exploration drilling, geophysical surveys and extrapolation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kapuni
Kapuni is an onshore natural gas-condensate field located in the Taranaki Basin, a ~100,000 km2 partially-inverted rift basin on the Taranaki Peninsula in the North Island, New Zealand. Discovered in 1959 and brought into production in 1970, Kapuni remained New Zealand's only producing gas-condensate field until the offshore Maui gas field began production in 1979. Geology Geologic history During the Lower Cretaceous (~150–100 Ma) Rangitata Orogeny, an accretionary wedge accumulated and was uplifted on the margin of Gondwana in present-day New Zealand. The resulting topography was eroded throughout the Cretaceous. After the Rangitata Orogeny, seafloor spreading commenced during the Middle Cretaceous. This resulted in the formation of the Tasman Sea as New Zealand separated from Australia. Normal faults, including the Manaia Fault, formed as the Taranaki Basin developed during seafloor spreading. Rifting continued until the Eocene (~56 Ma), when the Taranaki Basin u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maui Gas Field
The Maui natural gas field is the largest gas, natural gas condensate and oil field in New Zealand, producing nearly three-quarters of the country's hydrocarbons, as well as providing energy for electricity generation. It is located in the Tasman Sea, 35 km off the coast of Taranaki and to the southwest of New Plymouth. It covers an area of 157 square kilometres and is located in 110 metres of water. The gas field was discovered in 1969 by a joint venture of Royal Dutch/Shell, British Petroleum and Todd Petroleum. It was considered a "giant" field at the time of discovery. Government investment led to a government organisation later called Petrocorp taking a 50% interest. This was later bought out by Fletcher Challenge Energy. By the end of the Maui gas contract in 2009, the Maui Mining Companies were made up of Shell (83.75%), OMV New Zealand (10%), and Todd Energy (6.25%). OMV New Zealand owns and operates the Maui gas field having acquired the 83.75% share from Shell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barrel Of Oil Equivalent
The barrel of oil equivalent (BOE) is a unit of energy based on the approximate energy released by burning one barrel (, or ) of crude oil. The BOE is used by oil and gas companies in their financial statements as a way of combining oil and natural gas reserves and production into a single measure, although this energy equivalence does not take into account the lower financial value of energy in the form of gas. The U.S. Internal Revenue Service defines a BOE as equal to 5.8 million BTU. (, about Higher_heating_value">HHV.html" ;"title="Higher_heating_value.html" ;"title="/nowiki>Higher heating value">HHV">Higher_heating_value.html" ;"title="/nowiki>Higher heating value">HHV/nowiki>, or about .) The value is necessarily approximate as various grades of oil and gas have slightly different heating values. If one considers the lower heating value instead of the higher heating value, the value for one BOE would be approximately 5.4 GJ (see tonne of oil equivalent). Typically or ...
