Pipeline Infrastructure Basics

The U.S. has about 3 million miles of natural gas pipelines, enough to reach the moon and back six times. Moving gas and oil through those pipes is not passive: it requires compressor stations burning fuel, pump stations consuming electricity, and continuous monitoring. Pipeline transport is energy-intensive by necessity.

Natural gas pipelines use compressor stations every 60-100 miles to re-pressurize gas that has lost pressure to friction. These stations burn 3-5% of the gas they carry as fuel. A 1,000-mile pipeline consumes roughly 3-5% of its throughput just in transit. Oil pipelines use pump stations to overcome friction, consuming electricity rather than product. Pump stations are spaced based on terrain, viscosity, and throughput.

Both systems share a key feature: they are capital-intensive, geographically fixed, and long-lived (50+ years). Once built, a pipeline creates a physical connection between supply and demand that shapes market structure for decades. Moving the same energy by truck or rail costs 5-10 times more per ton-mile, which is why pipelines carry over 70% of U.S. crude oil and virtually all natural gas.

Worked Example

A natural gas pipeline carries 2 billion cubic feet per day over 1,200 miles. Compressor stations consume 4% of throughput.

• Calculate fuel consumed. 2,000,000,000 x 0.04 = 80,000,000 cubic feet/day.
• At roughly $3 per thousand cubic feet: 80,000 x $3 = $240,000/day in fuel costs.

Over a year, what does this fuel cost total?

$240,000 x 365 = $87.6 million/year. This is the operating cost of overcoming friction. It is why pipeline companies obsess over diameter (larger pipes have proportionally less friction) and why pipeline routes favor flat terrain.

Pipeline infrastructure is the physical backbone of fossil fuel delivery, and its fixed geography shapes energy markets, trade routes, and geopolitics.
