Exploration logging

Last updated

Exploration logging is the process of wireline logging, geophysical logging, geotechnical logging or geological logging of a drill hole, its core, or its rock cuttings for petrophysics or petrology. The practice is usually used in the mining, mineral exploration or oil and natural gas sectors. [1]

Petrophysics is the study of physical and chemical rock properties and their interactions with fluids.

Petrology The branch of geology that studies the origin, composition, distribution and structure of rocks

Petrology is the branch of geology that studies rocks and the conditions under which they form. Petrology has three subdivisions: igneous, metamorphic, and sedimentary petrology. Igneous and metamorphic petrology are commonly taught together because they both contain heavy use of chemistry, chemical methods, and phase diagrams. Sedimentary petrology is, on the other hand, commonly taught together with stratigraphy because it deals with the processes that form sedimentary rock.

Mining The extraction of valuable minerals or other geological materials from the earth

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit. These deposits form a mineralized package that is of economic interest to the miner.

Note that logging in this context does not refer to logging trees.

Logging

Logging is the cutting, skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. Logging is the process of cutting trees, processing them, and moving them to a location for transport. It is the beginning of a supply chain that provides raw material for many products societies worldwide use for housing, construction, energy, and consumer paper products. Logging systems are also used to manage forests, reduce the risk of wildfires, and restore ecosystem functions.

Mining engineering engineering discipline that involves the practice, the theory, the science, the technology, and applicatIon of extracting and processing minerals from a naturally occurring environment

Mining engineering is an engineering discipline that applies science and technology to the extraction of minerals from the earth. Mining engineering is associated with many other disciplines, such as mineral processing, Exploration, Excavation, geology, and metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations – from exploration and discovery of the mineral resource, through feasibility study, mine design, development of plans, production and operations to mine closure.

Agnico Eagle Mines Limited is a Canadian-based gold producer with operations in Canada, Finland and Mexico and exploration and development activities extending to the United States. Agnico Eagle has full exposure to higher gold prices consistent with its policy of no-forward gold sales. As of 2017, it has paid a cash dividend every year since 1983.

Anthony Francis Lucas Croatian oil explorer

Anthony Francis Lucas was an American Croatian-born oil explorer. With Pattillo Higgins he organized the drilling of an oil well near Beaumont, Texas that became known as Spindletop. This led to the widespread exploitation of oil and the start of the petroleum age.

Mineral rights are property rights to exploit an area for the minerals it harbors. Mineral rights can be separate from property ownership. Mineral rights can refer to sedentary minerals that do not move below the Earth's surface or fluid minerals such as oil or natural gas. There are three major types of mineral property; unified estate, severed or split estate, and fractional ownership of minerals.

Exploration diamond drilling

Exploration diamond drilling is used in the mining industry to probe the contents of known ore deposits and potential sites. By withdrawing a small diameter core of rock from the orebody, geologists can analyse the core by chemical assay and conduct petrologic, structural and mineralogical studies of the rock.

The Oregon Department of Geology and Mineral Industries (DOGAMI) is the agency of the government of the U.S. state of Oregon responsible for collecting, maintaining and disseminating geologic information, and regulation of industries which commercially develop the state's geological resources, including Natural gas, Crude oil, and other Mineral exploration and Mining.

Pebble Mine Place in Alaska, United States

Pebble Mine is the common name of a mineral exploration project investigating a very large porphyry copper, gold, and molybdenum mineral deposit in the Bristol Bay region of Southwest Alaska, near Lake Iliamna and Lake Clark. The proposal to mine the ore deposit using large-scale operations and infrastructure is controversial. Proponents argue that the mine will create jobs, provide tax revenue to the state of Alaska, and reduce American dependence on foreign sources of raw materials. Opponents argue that the mine would adversely affect the entire Bristol Bay watershed; and that the possible consequences to fish populations, when mining effluents escape planned containments, are simply too great of a risk. Much of this debate concerns the tentative plan to impound large amounts of water, waste rock, and mine tailings behind several earthen dams at the mine site. The project is on hold after the loss of funding partners in 2013. However, the EPA dropped its opposition to the mine in June 2019.

Mining industry of the Democratic Republic of the Congo

The Mining industry of the Democratic Republic of the Congo is a significant factor in the world's production of cobalt, copper, diamond, tantalum, tin, and gold. It is the Democratic Republic of the Congo's largest source of export income. In 2009, the Democratic Republic of the Congo (DRC) had an estimated $24 trillion in untapped mineral deposits, including the world's largest reserves of coltan and significant quantities of the world's cobalt. The United States Geological Survey estimates that the DRC has 1 million tons of lithium resources.

In 2006, Cambodia's mineral resources remained, to a large extent, unexplored. Between 2003 and 2006, however, foreign investors from Australia, China, South Korea, Thailand, and the United States began to express their interest in Cambodia's potential for offshore oil and gas as well as such land-based metallic minerals as bauxite, copper, gold, and iron ore, and such industrial minerals as gemstones and limestone.

Bisie is a tin deposit in the Walikale territory of the province of North Kivu in the Democratic Republic of the Congo (DRC), although the name is also sometimes used for the nearby village of Manoire. The mine was formerly an illegal source of an estimated 15,000 tons of tin, or 4% of global production. In early 2018 artisanal mining activity has stopped, and Alphamin Resources Corp., an exploration company, based in Mauritius, is leading an exploration of the site.

The El Indio Gold Belt is a mineral-rich region spanning the border between Chile and Argentina that contains large quantities of gold, silver and copper. On both sides of the border the belt is located within the Andes. The El Indio mine within the district was the first modern mine in Chile to produce gold as its main product. In Chile the main precious metal containing mineral is enargite. The El Indio belt is bordered in the north by another gold-silver mining district known as the Frontera District. Rodalquilarite, alunite and poughite are some of the minerals present in the area. The deposits of the belt formed during the Late Miocene period.

Mining in Taiwan used to be a great industry, especially for sulfur, clay, gold and coal. Nowadays, Taiwan lacks natural resources for mining and relies on imports to meet its demand for minerals. The current mining industries in Taiwan are of small and medium size in terms of exploited minerals and the scale of mining, mainly focusing on marble and limestone for cement, stone and craft industries and sand and gravel for construction industries. Mining activities in Taiwan are regulated by the Bureau of Mines of the Ministry of Economic Affairs.
