In its recently released Annual Energy Outlook 2015 (AEO2015), EIA expects the United States 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 U.S. natural gas and world prices that encourages exports of liquefied natural gas (LNG), and, to a lesser extent, greater exports by pipeline to Mexico.
The AEO2015 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 U.S. oil and natural gas resources. These assumptions significantly affect projected growth in annual net LNG exports 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 cubic feet (Tcf) in the Low Oil Price case to 10.3 Tcf in the High Oil and Gas Resource case. For comparison, 2040 natural gas net exports by pipeline range from 1.1 Tcf in the High Oil Price case to 2.9 Tcf in the High Oil and Gas Resource case.
Most of the growth in U.S. net natural gas exports occurs before 2030, as increased domestic natural gas supply satisfies new demand both internationally (with the development of LNG export capacity and growing demand for pipeline exports) and domestically (particularly in the industrial and electric power sectors). 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.
