Hot Oil Treatment
Definition - What does Hot Oil Treatment mean?
Hot Oil Treatment is the process of heating heavy and viscous crude oil with the help of hot oilers. Heavy crude oil has an API gravity of less than 22 degrees, is highly viscous and has a 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.
Petropedia explains Hot Oil Treatment
Hot oil treatment is made possible by the use of hot oilers. Hot oilers are generally truck mounted or skid mounted units whose primary purpose is to heat heavy crude oil or any treatment fluid. They are helpful in routine removal of wax deposits from the upper wellbore sections of a well 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. The heat energy given to the heavy crude oil helps in the removal of wax or paraffin, i.e., making it soft and removing the stickiness or reducing the viscosity and allowing crude oil to move quickly through the well tubing & pipelines.
