(Reuters] – The U.S.’s production growth has slowed, and many countries are searching for alternative suppliers after Russia invaded Ukraine.

Already, the United States is the largest natural gas producer in the world. However, the Appalachian Region and West Texas, which are the mainstays in production, see a slowing growth rate. Companies blame a lack of pipeline infrastructure for the slower growth, even though prices have risen to near 14 year highs.

U.S. gas prices rose about 50% since the invasion of Ukraine by Moscow on February 24th. European countries have looked to the United States to export more LNG to reduce dependence on Russian fuel.

Appalachia was the main source of U.S. gasoline in 2021. It has been difficult for oil companies to create new pipes that can move gas outside of West Virginia and Ohio.

The Permian Shale is the second-largest gas supply basin in America. It fills up quickly and analysts believe production growth will slow in Texas-New Mexico next year, unless new pipelines are built soon. In 2021, the Permian accounted for 19% of U.S. natural gas.

Analysts from energy expect that benchmark gas prices in 2022 will be $4.24 per Million British Thermal Units (mmBtu), which is the highest annual average for eight years.

Russia is the largest importer of LNG to Europe. The EU’s biggest economies consume 18.3 billion cubic feet daily (bcfd). The United States can currently export approximately 9.8 Bcfd of LNG. Although many businesses are trying to improve exports they cannot expect significant new LNG export capabilities for the next at least two decades.

One billion cubic feet of gas is sufficient to provide enough energy for approximately five million homes in the United States every day.

Appalachia was the mainstay of U.S. natural gas production for a decade. It has grown by 36% annually on average between 2010 and 2019.

Construction of pipelines has been slowing, and the average output growth fell to 4% between 2020-2021. EQT Corp. (NYSE:) declared on its earnings conference that growth won’t pick up until more pipelines are built.

Bank of America analysts (NYSE:) stated that Appalachia was “close to takeaway capacity limit limits”. They also estimated that the region would see “little or no production growth” before new pipelines are put into service. After costs increased from $6.0-$6.5 million to $8.2 billion, one giant project was cancelled, the Atlantic Coast Pipeline.

Another project that has been delayed for so long Equitrans Midstream (NYSE:) Corp’s Mountain Valley Line, worth $6.2 billion and running from West Virginia to Virginia has been delayed by ongoing litigation.

ClearView Energy Partners analysts estimate that Mountain Valley will be in service by mid-2023.

Permian Shale, the largest U.S. oilfield is located in Texas. Associated gas is a mixture of oil and gas that comes from the ground.

Crude oil costs hovering around $100/barrel, so analysts predict that energy firms will drill more oil in Permian to fill existing pipelines in 2023.

Permian gas production grew an average 17% annually between 2012 and 2020, then slowed to just 8% by 2021.

In the past, some gas was burned or flared by drillers. But pressure from states and investors to be more environmentally-friendly and cut greenhouse gas emissions have forced companies to reduce flaring.

Numerous energy companies have expressed interest in installing new Permian pipelines, which could include units from Enterprise Products Partners (NYSE). Kinder Morgan (NYSE: Energy Transfer (NYSE:).
