.... The hot oil treatments are usually done on a scheduled basis that is frequently determined by the treatments ineffectiveness. We hot oil the casing then we hot oil the flow line then we hot oil the tank bottom then we pump it down another well. Hot oiling has all of the following problems: It can...
