IntroductionThis study aims to develop students' ability to meet the terms often used in the field of Geology, whether in oil, mining and other ramifications

related to Earth Sciences.

PETROLEUM: is a naturally occurring flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface.

HYDROCARBONS: is anorganic compound consisting entirely of hydrogen and carbon.

REFINERY : is a production facility composed of a group of chemical engineering unit processes and unit operations refining certain materials or converting raw material into products of value.

WIDELY: by a large number of people; to a great extent; a lot.

CRUDE: Petroleum in its unprocessed form ("crude oil"), including: Brent crude oil, Heavy crude oil, Light crude oil, Sweet crude oil.

KEROSENE: is a combustible hydrocarbon liquid. The name is derived from Greek keros (κηρός wax). The word "Kerosene" was registered as a trademark by Abraham Gesner in 1854, and for several years, only the North American Gas Light Company and the Downer Company (to which Gesner had granted the right) were allowed to call their lamp oil "Kerosene" in the United States.

FIELDS: refers to Expanses of open ground or simply places, where oil is accumulated.

SULFUR: Sulfur or sulphur British English; see spelling below) is a chemical element with symbol S and atomic number 16. It is an abundant, multivalent non-metal.

NONRENEWABLE: A non-renewable resource is a natural resource which can not be reproduced, grown, generated, or used on a scale which can sustain its consumption rate, once depleted there is no more available for future needs. Also considered non-renewable are resources that are consumed much faster than nature can create them.

DRILLED: An implement with cutting edges or a pointed end for boring holes in hard materials, usually by a rotating abrasion or repeated blows.

COAL: is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams.

WOOD: is a hard, fibrous tissue found in many trees.

SHRINKS: To become reduced in amount or value; to become or cause to become smaller in size.

PEAT: (turf) is an accumulation of partially decayed vegetation.

SWAMPS: is a wetland that is forested. Many swamps occur along large rivers, where they are critically dependent upon natural water level fluctuations.

SANK: to displace part of the volume of a supporting substance or object and become totally or partially submerged or enveloped.

LIGNITE: is often referred to as brown coal, is a soft brown fuel with characteristics that put it somewhere between coal and peat.

BETUMINOUS COAL: is a relatively soft coal containing a tarlike substance called bitumen. It is of higher quality than lignite coal but of poorer quality than anthracite. It was usually formed as a result of high pressure on lignite. Bituminous coal is an organic sedimentary rock formed by diagenetic and sub metamorphic compression of peat bog material.

ANTHRACITE: is a hard, compact variety of mineral coal that has a high luster (radiance).

ASH: The grayish-white to black powdery residue left when carbon and hydrocarbons are burned.

FLY ASH: is the fine ash the flies up the chimney into the air when the ground coal is burned.

CHIMNEY: a structure for venting hot flue gases or smoke from a boiler, stove, furnace or fireplace to the outside atmosphere. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney, effect
