Five petroleum product pipelines were completed in the United States in 2024

---

In 2024, pipeline companies completed five pipeline projects to transport petroleum liquids in the United States, according to our recently updated Liquids Pipeline Projects Database. The five projects consisted of three hydrocarbon gas liquid (HGL) pipelines and two petroleum product pipelines.

The completed projects are:

• Texas Western Products system
  Enterprise Products Partners’ Texas Western Products system is a conversion and reversal of a 60,000-barrel-per-day (b/d) pipeline that transports refined products (gasoline and diesel) from the Texas Gulf Coast to markets in the Mid-continent and Rocky Mountain regions. The system serves four key destinations: Gaines County, Texas; Jal, New Mexico; Albuquerque, New Mexico; and Grand County, Utah. It was completed in the fourth quarter of 2024.
• Houston to El Paso refined petroleum products pipeline
  ONEOK’s Houston to El Paso refined petroleum products pipeline system is a 30,000-b/d expansion along its existing route between Odessa and Crane, Texas. The new 30-mile, 16-inch pipeline increases the total capacity to approximately 100,000 b/d from Gulf Coast and Mid-Continent refineries to El Paso. It was completed in the first quarter of 2024.
• Daytona NGL Pipeline
  Targa Resource’s Daytona NGL Pipeline is a 400,000-b/d pipeline that transports Y-grade natural gas liquids (NGLs) from the Permian Basin to North Texas, where it connects with Targa’s Grand Prix NGL Pipeline. From there, NGLs move to Targa’s fractionation and storage complex in Mont Belvieu, Texas. The pipeline is approximately 400 miles in length with a 30-inch diameter and was completed in the fourth quarter of 2024.
• Seminole Red Pipeline
  Enterprise Products Partners’ Seminole Red Pipeline is a conversion of a 280,000-b/d crude oil pipeline back to an HGL pipeline while the company builds the Bahia Pipeline, another HGL pipeline project that will also service the Permian Basin. The pipeline transports Y-grade NGLs approximately 440 miles from the Permian Basin in West Texas to Enterprise’s fractionation and storage facilities in Mont Belvieu, Texas. The Seminole Red Pipeline was originally an HGL pipeline before it was converted to a crude oil pipeline in 2019. The conversion back to HGL service was completed in the first quarter of 2024.
• West Texas NGL Loop
  The West Texas NGL Loop developed by ONEOK is a 40,000-b/d expansion that increased the total pipeline capacity to 515,000 b/d. The looping expansion involved installing additional pipeline segments in parallel to the existing line, which extends along the West Texas NGL Pipeline route from the Permian Basin to multiple fractionation and storage facilities in Mont Belvieu, Texas. The company completed the project in the fourth quarter of 2024 and plans to add pump stations by mid-2025 to further expand capacity to 740,000 b/d.

Our Liquids Pipeline Projects Database contains information about projects at various stages of construction. In addition to these completed projects, we estimate there are nine announced pipeline projects and eight projects under construction in the United States. We estimate 17 projects have been permanently canceled since 2020.

Our Liquids Pipeline Projects Database compiles information on more than 270 future, ongoing, and past liquids pipeline projects in the United States. These pipelines carry crude oil, HGLs, and petroleum products—which include gasoline, diesel, jet fuel, and other refinery products. This database includes projects that date back to 2010. Our database contains project types, start dates, capacity, mileage, geographic information, and project status. We track expanded, reversed, converted, and new pipeline projects.

Some projects are connected to each other, with some pipelines doubling as segments of other longer lines that may carry the same fuels to their final destination. As a result, adding together the capacity of all projects would result in overestimating or double counting some pipeline capacity.

The Liquids Pipeline Projects Database complements our Natural Gas Pipeline Projects tracker. We update our Liquids Pipeline Projects Database based on the best available information from pipeline company websites, trade press reports, and government documents, such as U.S. Department of State permits for border crossings. We update the database twice each year. The data reflect reported plans and do not reflect our assumptions on the likelihood or timing of project completion.
