Coniferous Trees: The largest and most widely distributed order of gymnosperms, containing about 49 genera with approximately 570 species most of which are evergreen trees. Typically, conifers show a pyramidal growth pattern and bear simple leaves, often needles or scales. Conifers are also commercially important as a source of timber for the papermaking, building, and furniture industries. They are generally faster growing and develop a less dense wood than other trees. They are also known as softwood trees or Coniferales.
Conservation: The planning and management of resources so as to secure their wise use and continuity of supply while maintaining and enhancing their quality, value, and diversity.
Cuttings: Chips and small fragments of rock cut by a drill bit and brought to the surface by the flow of drilling mud.
Deciduous Trees: In the Northern Hemisphere these trees grow in forests often referred to as "Deciduous Summer Forests" and typically have a 5-6 month growing season that may range from between 150 to 200 days. These trees, also called hardwoods, are characterized by green leaves that shed when the weather gets cool, like in autumn. Several trees make up a deciduous forest including broadleaf deciduous hardwood trees such as oak, hickory, maple, ash, beech and others. They are important to the forestry industry and are used to make many familiar products such as furniture and boxes.
Density: The heaviness of crude oil, indicating the proportion of large, carbon-rich molecules, generally measured in kilograms per cubic metre, or degrees on the American Petroleum Institute (API) gravity scale. In Western Canada oil up to 900 kilograms per cubic metre is considered light to medium crudeoil above this density is deemed as heavy oil or bitumen.

Flaring: Flaring is the burning of natural gas that cannot be processed or sold. Flaring disposes of gas, and it releases emissions into the atmosphere. Today it is an important safety measure at natural gas facilities.
Geophysics: The science that deals with the relations between the physical features of the Earth and forces that produce them. Geophysics includes the study of seismology and magnetism.
Gusher: A well that comes in with such great pressure that the oil or gas blows out of the wellhead like a geyser. Gushers are rare today because of improved drilling technology, especially the use of drilling mud to control downhole pressure.
Hay: Dry fodder for animals made from plants.
Hay Rack: Farm wagons that have been adapted with a large basket deck to haul hay.
Hot Water Process: A method for separating bitumen from oil sand using hot water and caustic soda, developed by Karl Clark of the Alberta Research Council.
Hydrocarbons: A large class of liquid, solid or gaseous organic compounds, containing only carbon and hydrogen, that are the basis of almost all petroleum products.
In-situ: In its original place; in position; in-situ recovery refers to various methods used to recover deeply buried bitumen deposits, including steam injection, solvent injection and firefloods.
Kelly: The first and sturdiest joint of the drill string in conventional rotary drilling rigs. A thick-walled, hollow steel forging with four flat sides that fits into a square hole in the rotary table.
Landman: A member of the exploration team whose primary duties are formulating and carrying out exploration strategies and managing an oil company's relations with its landowners and partners, including securing and administering oil and gas leases and other agreements.
Lease: An agreement between two or more parties where the owner of the land grants another party the right to drill and produce petroleum substances in exchange for payment.
Light Crude Oil: Liquid petroleum that has a low density and flows freely at room temperature.
Limestone: Calcium carbonate-rich sedimentary rocks in which oil or gas reservoirs are often found.
Luvisolic Soil: Luvisolic soils develop on a wide variety of parent materials underneath mixed deciduous-coniferous forests. They cover 52 percent of the province and are generally found in imperfectly drained to moderately well-drained sites. Most luvisols tend to be less productive for agricultural purposes because of their lower organic content and shorter growing season.
Medium Crude Oil: Liquid petroleum with a density between that of light and heavy crude oil.
Mineral Rights: The rights to explore for and produce the resources below the surface.
Mower: A machine designed to cut grasses and other forage crops to be cured for hay.
Non-Renewable Resource: Natural resources that cannot be regenerated in a human life span.
Oil Sands: A deposit of sand saturated with bitumen.
Overshot Stacker: This is a large fork mounted on two long arms. The fork swings up until the hay falls backwards off the fork on to the top of the stack.
Paleontologist: A person trained in paleontology - the study of plant and animal life in past geological time through the study of fossil plants and animals, their relationship to present-day plants and animals and their environments.
Palynologist: A paleontologist who specializes in fossil pollens and spores.
Petroleum: A naturally occurring mixture composed predominantly of hydrocarbons in the gaseous, liquid or solid phase.
Pinnacle Reef: A conical formation, higher than it is wide, usually composed of limestone, in which hydrocarbons might be trapped.
Pool: A natural underground reservoir containing an accumulation of petroleum.
Porosity: The volume of spaces within rock that might contain oil and gas (like the amount of water a sponge can hold); the open or void space within rock.
