Can raw crude oil be transported on us inland water ways to refineries?
yes it can
Water and food substances or nutrients are transported throughout the plant through the vascular bundle formed from the cambium. Xylem transports water from the roots to the leaves. The water it transports is needed by the plant in photosynthesis. After photosynthesis, sugar and other nutrients are produced and they are transported throughout the plant by the phloem.

You probably mean the "specific gravity" of crude oil. The answer is yes. For example: crude oil with a specific gravity of less than 1.0 and is therefore lighter than water and will float on its surface. "Extra heavy crude oil" has a specific gravity greater than 1.0 and sinks to the bottom of water.
