The installation of permanent wellhead equipment for the production of oil and gas.

An engine used to increase the pressure of natural gas so that it will flow more easily through a pipeline. A compressor normally uses positive displacement to compress the gas to higher pressures so that the gas can flow into pipelines and other facilities.

Concentrate is a fine powder-like product between ore and metal where much of the waste mineral has been eliminated, leaving a higher concentration of the required mineral than in the original ore. 

Hydrocarbons which are in the gaseous state under reservoir conditions and which become liquid when temperature or pressure is reduced.Its presence as a liquid phase depends on temperature and pressure conditions in the reservoir allowing condensation of liquid from vapour. Gas produced in association with condensate is called wet gas.

Continuous casting is the process in which molten steel is poured into a water-cooled copper mould allowing it to gradually solidify as it moves down the mould. Once the steel solidifies it becomes known as a steel billet, bloom, or slab. The process has become the preferred method for making semi-finished steel because of much better yield, productivity and cost performance. 

Copper is a chemical element with the symbol Cu and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.  Copper is a major component in EVs used in electric motors, batteries, inverters, wiring and in charging stations. 

Corex is the reduction process for production of hot metal from iron ore using coal. It is a coal-based smelting process that yields hot metal or pig iron. The process gasifies non-coking coal in a smelting reactor, which also produces liquid iron. The gasified coal is fed into a shaft furnace, where it removes oxygen from iron ore lumps, pellets, or sinter; the reduced iron is then fed to the smelting reactor.

Coring describes the process of taking rock samples from a well by means of a special tool called a core barrel. The core barrel itself may be thought of as a special storage chamber for holding the rock core. The core catcher serves to grip the bottom of the core and, as tension is applied to the drillstring, the rock under the core breaks away from the undrilled formation below it.

Critical minerals are metals and non-metals that are considered vital for the economic well-being of the world's major and emerging economies, yet whose supply may be at risk due to geological scarcity, geopolitical issues, trade policy or other factors. Among these important minerals are metals and semi-metals used in the manufacture of mobile phones, flat screen monitors, wind turbines, electric cars, solar panels, and many other high-tech applications.

This is a general term for unrefined petroleum or liquid petroleum

Crude steel is iron that has been decarburized to remove part of the carbon in the molten metal but that has not yet been refined into a definite steel grade.

A standard unit used to measure the quantity of gas (at atmospheric pressure); 1 cubic foot = 0.0283 cubic meters.

Rock chips cut from the formation by the drill bit, and brought to the surface with the mud. Used by geologists to obtain formation data.

Cut-To-Length in the process where sections of flat-rolled steel is cut into a particular or desired length or shape. Such product that is cut to length is normally shipped flat-stacked.

Combined water and power is similar to CHP, but in this instance the waste heat is used toproduce potable water.
