Demand for equipment used in midstream oil and gas applications in the U.S. is projected to decline to $10.5 billion in 2019 as low oil and gas prices limit production growth and U.S. midstream infrastructure becomes better adapted to the recent shifts in energy production.

That trend and others are presented in “Midstream Oil & Gas Equipment,” a new study published March 21 by Freedonia Group, a Cleveland-based industry research firm.

While demand will be significantly lower in 2016, the market for midstream equipment is expected to return to healthy levels of demand by 2019. Spending on equipment for use in crude-by-rail and gas processing plants will both fall from elevated 2014 levels, but pipeline construction and LNG activity will continue to support a high level of demand, the report concluded.

Significant declines in equipment demand are forecast in 2016, driven by a dramatic fall in well completions after the collapse of oil prices since mid-2014. A recovery in drilling and completion activity is expected by 2019, however, with the upstream sector benefiting from improved cost efficiency, an eventual price recovery, and the presence of new export opportunities for both crude oil and LNG.

In turn, better conditions in the upstream market will promote demand for equipment used in new gathering and transmission pipelines, storage facilities, and other types of midstream infrastructure, Freedonia added.

The largest product category in midstream oil and gas equipment will remain line pipe, where demand is expected to almost fully recover by 2019 despite a sharp decline in 2015 and 2016. Although demand for these products will not recover to the elevated levels seen in 2014, equipment associated with natural gas infrastructure—including gas treating and processing equipment and compressors used in pipelines—will continue to be strong by historical standards.

The rapid growth of natural gas production in the Marcellus and Utica plays of the Appalachian Basin has required high levels of new gas processing and pipeline infrastructure to meet changing gas transportation dynamics. By 2019, the need for more construction there will begin to ebb, the report said.

Although the prospects for LNG export facilities are clouded by short-term price uncertainty, market fundamentals will drive the eventual construction of a number of facilities in coming years. These facilities, each of which will be a major investment, will boost the overall market for a range of equipment, including compressors, valves, and pumps. Additionally, several new projects will require construction of LNG storage tanks, which can make up a large part of total project cost due to their size and heavy engineering requirements.

Crude-by-rail has become a major component of U.S. midstream infrastructure over the past few years, resulting in a very high level of orders for new tank cars, Freedonia found. Additionally, new Department of Transportation regulations require that most tank cars in service be replaced or retrofitted with additional safety equipment over the next few years. Together, these factors will result in continued spending in this segment of the market.

However, growth in pipeline capacity connecting areas such as the Bakken play in the upper Midwest and producing areas in the Rocky Mountains with refineries in other parts of the country will reduce the need for crude transportation by rail through 2019, it added.

The study includes details on these and other findings. The study presents historic demand data from 2004, 2009 and 2014, plus forecasts for 2019 and 2024, by product, application and U.S. region. The study also assesses key market environment factors, analyzes the industry structure, evaluates company market share and profiles 37 industry players.
