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 und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oil And Gas Industry In New Zealand
The oil and gas industry in New Zealand explores and develops oil and gas fields, and produces and distributes petroleum products and natural gas. In 2022, New Zealand's net self-sufficiency in oil (production divided by consumption) was 12%, i.e. the country imported much more crude and refined oil than it exported. All crude oil extracted in New Zealand was (and is) exported as the Marsden Point refinery was not suited to processing it. In 2018, 60 petajoules of crude were produced in New Zealand, 380 PJ of petroleum products imported (most of it crude), and 283 PJ consumed. The difference is exported or used for international travel (aviation fuel and similar). Oil and gas are produced from 21 petroleum licenses / permits, all in the Taranaki basin. The most important fields are Kapuni, Maui gas field, Maui, Pohokura field, Pohokura and Kupe field, Kupe. Exploration for oil and gas reserves includes the Great South Basin and offshore areas near Canterbury and Gisborne. New Ze ...

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 Trough, 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 600 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 contain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Todd Corporation
The Todd Corporation Limited is a privately held conglomerate based in New Zealand, owned and controlled by the Todd family and headquartered in Wellington, New Zealand. The corporation is currently led by board chair, Nick Olson, and group chief executive officer, Evan Davies. The corporation employs 800 individuals at 10 locations in New Zealand, Australia, and Canada including seven on the executive team. The board of directors has seven members. History The history of Todd Corporation is understood to have begun in 1885 when Scottish immigrant Charles Todd founded and opened a fellmongery and wool scouring business (according to Todd Energy) in the small Central Otago town of Heriot. By 1929, it had evolved into a car sales and maintenance business run by his son and namesake Charles Todd after the company began importing motor vehicles. This automotive business would define the Todd family business until well into the 1980s. Charles Todd was credited with bringing the ...

Taranaki
Taranaki is a regions of New Zealand, region in the west of New Zealand's North Island. It is named after its main geographical feature, the stratovolcano Mount Taranaki, Taranaki Maunga, formerly known as Mount Egmont. The main centre is the city of New Plymouth. The New Plymouth District is one of three in the region and is home to more than 65 per cent of the population of Taranaki. The Stratford District includes the main centres of Stratford, New Zealand, Stratford, Midhirst, Toko and Whangamōmona, Whangamomona. The South Taranaki District includes Hāwera, Manaia, Taranaki, Manaia, Eltham, New Zealand, Eltham, and Ōpunake. Since 2005, Taranaki has used the promotional brand "Like no other". Geography Taranaki is on the west coast of the North Island, surrounding the volcanic peak of Mount Taranaki. The region covers an area of 7258 km2. Its large bays north-west and south-west of Cape Egmont are North Taranaki Bight and South Taranaki Bight. Mount Taranaki is t ...

Energy In New Zealand
Despite abundant natural resources and a relatively small population, New Zealand is a net importer of energy, in the form of petroleum products. The ratio of non-renewable and renewable energy sources was fairly consistent from 1975 to 2008, with about 70 per cent of primary energy supply coming from hydrocarbon fuels. This ratio decreased to about 60 per cent in 2018. The proportion of non-renewable energy varies annually, depending on water flows into hydro-electricity lakes and demand for energy. In 2018, approximately 60% of primary energy was from non-renewable hydrocarbon fuels and 40% was from renewable sources. In 2007 energy consumption per capita was 120 gigajoules. Per capita energy consumption had increased 8 per cent since 1998. New Zealand uses more energy per capita than 17 of 30 OECD countries. New Zealand is one of 13 OECD countries that does not operate nuclear power stations. From 1994 to 2018, the energy intensity of the economy per unit of GDP declined b ...

Gas Reinjection
Gas reinjection is the reinjection of natural gas into an underground reservoir, typically one already containing both natural gas and crude oil, in order to increase the pressure within the reservoir and thus induce the flow of crude oil or else sequester gas that cannot be exported. This is not to be confused with gas lift, where gas is injected into the annulus of the well rather than the reservoir. After the crude has been pumped out, the natural gas is once again recovered. Since many of the wells found around the world contain heavy crude, this process increases their production. The basic difference between light crude and heavy crude is its viscosity and pumpability—the lighter the crude the easier it is to pump. Recovery of hydrocarbons in a well is generally limited to 50% (heavy crudes) and 75–80% (light crudes). Recycling of natural gas or other inert gases causes the pressure to rise in the well, thus causing more gas molecules to dissolve in the oil loweri ...

Hydraulic Fracturing
Fracking (also known as hydraulic fracturing, fracing, hydrofracturing, or hydrofracking) is a well stimulation technique involving the fracturing of Formation (geology), formations in bedrock by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other hydraulic fracturing proppants, proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures open. Fracking, using either hydraulic pressure or acid, is the most common method for well stimulation. Well stimulation techniques help create pathways for oil, gas or water to flow more easily, ultimately increasing the overall production of the well. Both methods of fracking are classe ...

Natural Gas Liquids
Natural-gas condensate, also called natural gas liquids, is a low-density mixture of hydrocarbon liquids that are present as gaseous components in the raw natural gas produced from many natural gas fields. Some gas species within the raw natural gas will condense to a liquid state if the temperature is reduced to below the hydrocarbon dew point temperature at a set pressure. The natural gas condensate is also called condensate, or gas condensate, or sometimes natural gasoline because it contains hydrocarbons within the gasoline boiling range, and is also referred to by the shortened name condy by many workers on gas installations. Raw natural gas used to create condensate may come from any type of gas well such as: * Crude oil wells: Natural gas that comes from crude oil wells is typically called ''associated gas''. This gas could exist as a separate gas cap above the crude oil in the underground reservoir or could be dissolved in the crude oil, ultimately coming out of solut ...

Royal Dutch Shell
Shell plc is a British multinational oil and gas company, headquartered in London, England. Shell is a public limited company with a primary listing on the London Stock Exchange (LSE) and secondary listings on Euronext Amsterdam and the New York Stock Exchange. A core component of Big Oil, Shell is the second largest investor-owned oil and gas company in the world by revenue (after ExxonMobil), and among the world's largest companies out of any industry. Measured by both its own emissions, and the emissions of all the fossil fuels it sells, Shell was the ninth-largest corporate producer of greenhouse gas emissions in the period 1988–2015. Shell was formed in April 1907 through the merger of Royal Dutch Petroleum Company of the Netherlands and The "Shell" Transport and Trading Company of the United Kingdom. The combined company rapidly became the leading competitor of the American Standard Oil and by 1920 Shell was the largest producer of oil in the world. Shell first ente ...

Fault (geology)
In geology, a fault is a Fracture (geology), planar fracture or discontinuity in a volume of Rock (geology), rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust (geology), crust result from the action of Plate tectonics, plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction, subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the Plane (geometry), plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geological maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone ...

Stratigraphic Column Of Kapuni Reservoirs
Stratigraphy is a branch of geology concerned with the study of rock layers (strata) and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks. Stratigraphy has three related subfields: lithostratigraphy (lithologic stratigraphy), biostratigraphy (biologic stratigraphy), and chronostratigraphy (stratigraphy by age). Historical development Catholic priest Nicholas Steno established the theoretical basis for stratigraphy when he introduced the law of superposition, the principle of original horizontality and the principle of lateral continuity in a 1669 work on the fossilization of organic remains in layers of sediment. The first practical large-scale application of stratigraphy was by William Smith in the 1790s and early 19th century. Known as the "Father of English geology", Smith recognized the significance of strata or rock layering and the importance of fossil markers for correlating strata; he created the first geological map ...
