中文 (征集中)


A transaction that results in the transportation of gas in a direction opposite of the aggregate physical flow of gas in the pipeline. This is typically achieved when the transporting pipeline redelivers gas at a point(s) upstream from the point(s) of receipt. A back haul condition will exist as long as the aggregate backhaul transactions total less than the aggregate forward haul transactions. A back haul transaction can result in a delivery by non-delivery or cut back (reduction) of physical flow at a delivery point. For refined oil products, a backhaul is simply the delivery of one product by tank truck, barge, or rail and the use of the vessel to transport back (back haul) another product
