The US as a natural gas exporter

The US as a natural gas exporter

The EIA has said that it expects the US to be a net natural gas exporter by 2017. After 2017, natural gas trade is driven largely by the availability of natural gas resources and by world energy prices. Increased availability of domestic gas or higher world energy prices each increase the gap between the cost of US natural gas and world prices that encourages exports of LNG, and, to a lesser extent, greater exports by pipeline to Mexico.


The Annual Energy Outlook 2015 examines alternate cases with higher and lower world oil price assumptions, which serve as a proxy for broader world energy prices given oil indexed contracts, as well as with higher assumed US oil and natural gas resources. The assumptions significantly affect projected growth in annual net LNG export after 2017. Net LNG exports make up most of the natural gas exports in most cases. By 2040, LNG exports range from 0.2 trillion ft3 in the low oil price scenario to 10.3 trillion ft3 in the high oil and gas resources scenario. In comparison, 2040 natural gas net exports by pipeline range from 1.1 trillion ft3 in the high oil price scenario to 2.9 trillion ft3 in the high oil and gas resource scenario.


Most of the growth in US net natural gas exports occurs before 2030, as increased domestic natural gas supply satisfies new demand international and domestically. Increased shale gas production accounts for three quarters of the increase in total dry gas production. More than half of the increase in shale gas production comes from the Haynesville and Marcellus formations.

Natural gas exports are highest in the high oil and gas resources case, which assumes both higher resources and improvements in technology to bring those resources to market. In this case, both net LNG and net pipeline exports in 2040 are higher than in any other AEO2015 case, because higher production capability lowers the cost of US natural gas compared with prices in the world market. In the high oil price and low oil price cases, projected LNG exports vary in response to the price of oil linked international LNG contracts. Contract prices are higher in the high oil price case, making US LNG exports more competitive, while the opposite occurs in the low oil price case. However, the relationship between international LNG prices and world oil prices is assumed to weaken later in the projection period, with the most decoupling of oil and natural gas prices occurring in the high oil price case.

Mexico and Canada

US pipeline exports of natural gas, most flowing to Mexico, increase in all the AEO2015 cases because increases in Mexico’s production are not expected to keep pace with its growing natural gas demand. On the import side, pipeline imports from Canada, which accounted for 97% of total US gross total imports of natural gas in 2013, continue as the source of nearly all US gross natural gas imports through 2040, except in the low oil price case, where there is significantly greater growth in gross imports of relatively less expensive international LNG.
