Cleaner fossil fuel from two major shale plays

Boardwalk/Gulf Crossing Pipeline Company / Louisiana, Oklahoma, Texas


According to a 2012 report by KPMG, “Over the past few years, advancements in drilling technology have opened up huge shale gas reserves in the United States.” Shale gas is expected to account for 45% of US natural gas supplies in 2035, up from 20% in 2010.

Barnett and Woodford are among six major US shale plays listed by KPMG. “In 2009,” the report says, “the Barnett shale play was the most prolific play, accounting for almost 62% of the total shale gas production.”

The Gulf Crossing Pipeline Company, a subsidiary of Boardwalk Pipeline Partners, created a pipeline to move gas from the Barnett Shale and Oklahoma’s Woodford Shale to markets across the US. The 42-inch pipeline runs 357 miles from Sherman, Texas, to Perryville, Louisiana.


Following previous projects with Mott MacDonald, Boardwalk Pipeline Partners retained us in 2008 to provide construction survey, mapping, and related engineering services for the Gulf Crossing Pipeline.

We also supported Gulf Crossing with the Federal Energy Regulatory Commission (FERC) 7(c) variance process and produced as-built alignment drawings and weld maps.

The Gulf Crossing Pipeline was completed in the first quarter of 2009. It has a peak-day delivery capacity of approximately 1.7 billion cubic feet.


Mott MacDonald was able to fulfill the client’s staffing needs quickly and efficiently. Within two days of the client’s request, we provided 19 construction survey crews. We continued to add survey crews based on project needs, eventually providing 67 crews (221 total staff) within the necessary timeframe.

The completed project supports the market position of Boardwalk Pipeline Partners, whose systems carry about 12% of the country’s average daily consumption of natural gas. Markets for gas from the pipeline are in the Midwest, Northeast, Southeast and Florida.
