 Fallout from the oil price war extends far beyond U.S. crude production. Americas liquefied petroleum gas LPG exports are also in the crosshairs.The global LPG trade rose 14 in 2019, to an all-time-high 109 million tons, with almost all of the seaborne volume evenly split between exports from the Middle East and U.S. Gulf. John Hadjipateras, CEO of Dorian LPG NYSE: LPG, said on his companys Feb. 5 quarterly call that it appears annual U.S. export volumes will surpass the Middle East for the first time in 2020.But the world has dramatically changed since Hadjipateras made that statement. It now appears U.S. LPG exports will fall back and Middle East exports will rise.LPG market dynamicsLPG is an associated-gas byproduct of the crude and natural gas drilling process and a byproduct of the crude-refining process. Propane and butane are the primary LPG cargoes.Just over half of LPG is used around the world for cooking and heating, with most of the remainder used as feedstock for the petrochemical industry. In the latter case, LPG competes with naphtha, which is created by refining crude oil. Asian and European petrochemical producers switch between using LPG and naphtha as a feedstock, depending on which is cheaper.LPG is transported on long-haul routes aboard vessels known as very large gas carriers VLGCs that have a capacity of around 84,000 cubic meters. The top listed VLGC owners are Dorian in the U.S. and BW LPG and Avance Gas in Norway.Shift to the Middle EastThe plunge in crude oil pricing driven by the Saudi production surge is likely to reduce U.S. LPG output.The preponderance of incremental U.S. LPG production would be from associated gas from drilling in the West Texas Permian Basin, explained Stifel analyst Ben Nolan during this weeks Virtual Investor Forum, hosted by J Mintzmyer on Value Investors Edge via Seeking Alpha.Permian Basin crude production is expected to be heavily curtailed. If the U.S. scales back crude production, we will see a reduction of associated gas coming out of there in the future, said John Lycouris, CEO of Dorian LPG subsidiary Dorian LPG USA LLC, during the Virtual Investor Forum.However, Lycouris emphasized that with the amount of crude oil thats going to be produced globally, theres going to be plenty of associated gas from the countries producing more crude countries in the Middle East and also Russia.That means there will perhaps be a shift in the next few months, with more gas coming out of the Middle East than out of the U.S. Gulf.If so, continued Lycouris, were going to have an increase in shipping demand from the Middle East and we expect that whatever utilization might be lost from the U.S., if any, would be mopped up very quickly by Middle East demand.Ton-mile effectVLGC demand is measured in ton-miles volume multiplied by distance. The shorter the voyage distance, the lower the vessel demand for the same cargo volume.The voyage between Ras Tanura, Saudi Arabia, and Chiba, Japan, is 29 shorter than from Houston to Chiba via the Panama Canal. Thus, if the volume of LPG transported by sea remains the same but more comes out of the Middle East than the U.S. Gulf, its negative for VLGC demand.Dorian LPG CFO Ted Young characterized the voyage distance for U.S. and Middle East exports as not a whole lot different and affirmed that Dorian is somewhat indifferent to where exports come from as long as the products are moving on our ships.Demand destruction ahead?The worst-case scenario for VLGC owners would be for Asian petrochemical producers to opt for naphtha over LPG as a feedstock.

For heating and cooking, youve got the hardware in your home. Thats not going to change. Theres going to continue to be demand for that.
