Zusammenfassung:	A method of producing and transporting crude oil, comprising extracting crude oil from a well; placing the crude oil in a pipeline to transport the crude oil away from the well, wherein at least a portion of the pipeline travels through an atmosphere having an ambient temperature less than 20 °C; and transporting the crude oil for a first time period at a low flow rate so that a precipitate forms on an inner wall of the pipeline; and transporting the crude oil for a second time period at a high flow rate so that the precipitate is cleared from the inner wall of the pipeline.
