Definition - What does Hot Oil mean?
Hot Oil is heavy crude oil which has high viscosity and high sulfur content. In order to increase the mobility of heavy crude oil, it is heated to a certain temperature so that it can easily move through pipelines without sticking. This heated heavy crude oil is also known as hot oil.
Petropedia explains Hot Oil
Heavy crude oil is heated and converted into hot oil with the help of hot oilers. These are generally truck mounted or skid mounted units whose primary purpose is to heat heavy crude oil or any treatment fluid. Hot oilers are very much helpful in routinely removal of wax deposits from the upper wellbore sections of wells in cold climates where low wellhead temperatures increase the susceptibility of heavy crude oil and wax precipitation. A hot oil unit is designed to clear these blockages by circulating the heated fluid into piping, tubing, casing or tanks. High-pressure units remove paraffin from well tubing & pipelines.
