(1) Crude oil wells - Raw natural gas that comes from crude oil wells is called associated gas. This gas can exist separate from the crude oil in the underground formation, or dissolved in the crude oil. (2) Dry gas wells - These wells typically produce only raw natural gas that does not contain any hydrocarbon liquids.

Asphalt oxidation is a complex controlled exothermic reaction process involving the reaction and rearrangement of asphalt molecules in the presence of oxygen at elevated temperatures (such as in a blow still or rooftop). The process includes dehydrogenation, aromatization, oxygen uptake, and a loss of volatile material.

 · There are a few different ways to mix asphalt, the most popular of which are hot and cold. Hot-mix asphalt is made by heating aggregates to decrease the viscosity of the binding agents and make the whole more fluid, then drying it to remove any remaining moisture. It is mixed hot at 200-350 degrees Fahrenheit.
