Can you guess the second most-traded product in the world? You probably have a good idea if you work in the oil and gas industry. It is refined petroleum—which includes gasoline for our cars and other oils. Oil and gas is a $2 trillion industry that spans terms. The objective of this glossary is to provide our clients with a useful reference guide to the language of commodity trading and risk management. Additionally, this glossary may be a valuable resource for educating key stakeholders within the oil and gas, utilities and mining industries, including employees, customers, shareholders and Natural gas. A naturally occurring combination of hydrocarbon gasses that is expansible and highly compressible. One of the main constituents of natural gasses is methane, but it also includes lesser quantities of propane, ethane, pentane, and butane. Helium, carbon dioxide, hydrogen sulphide, and nitrogen may also be present in big proportions. Brine: Another word for salt water. Borehole: The hole drilled by the drilling bit. Cap rocks: Rocks geologists look for that trap the oil and gas so they cannot rise to the surface over time. Casing: Pipe cemented to the wall of the drilled well to seal off the water supply and to keep the hole from collapsing. Gas Well: A well completed for the production of natural gas from one or more gas zones or reservoirs. Such wells contain no completions for the production of crude oil. Gas wells are defined by EIA using a gas/oil ratio (GOR) of 6000 cf/bbl: Wells with a GOR greater than 6000 are labeled gas wells while a GOR of 6000 or less are labeled oil wells API Gravity. Industry scale expressing the gravity or density of liquid petroleum products. The measuring scale is calibrated in terms of degrees API; it may be calculated in terms of the following formula: Degrees API = 141.5/ sp.gr.60°F/60°F -131.5. The higher the API gravity, the lighter the compound. Abbreviation for barrels of oil per day. boulder. A rounded rock fragment greater than 256 mm in diameter. BS&W. Acronym for basic sediment and water. Br. Abbreviation for bromine. bubble point pressure. The pressure at which the first bubbles of gas appear from the liquid phase. Ca. Abbreviation for calcium. calcareous. Containing calcium Casing: A steel pipe that's placed in an oil or gas well after drilling is completed to prevent the well hole from caving in. Casing also prevents fluids from moving from one formation (like groundwater) to another and helps in well control. Drill Rig: The machinery that's used to drill oil and gas wells. Associated gas is recovered from an oil well through two-phase (gas and oil) or threephase (gas, oil and water) separation by using the - densi
