Describe the role of gathering lines and trunk lines in pipeline operations.
(72) VerifiedGathering lines are smaller pipelines that go from an active well to a major trunk line. The trunk lines go to an oil or gas field but do not go to individual wells. Gathering lines are relatively small in diameter. They usually do not exceed 8 inches in diameter. In contrast trunk lines are usually 30-50 inches in diameter.Gathering lines are frequently laid on the surface of the ground to ensure ease of relocation when a well or field runs dry.Trunk lines,on the other hand,are usually seen as permanent and are laid underground.
The term trunk line is often used in conjunction with oil movements and can refer to crude oil trunk lines or oil product lines.Oil trunk lines move oil to tank farms or refineries in distant locations,whereas oil product lines move the gasoline,jet fuel,and home heating oil from refineries to market areas.Technically,any long-distance movement via a large-diameter,permanent pipeline implies a trunk-line movement.Therefore,when coal,natural gas,or chemicals move via pipelines,that movement is classified as trunk-line movement.
Which of the following is not a commodity that water and rail competes to move?
