What is the pressure range at which gas is sent from wells through the Interstate Pipeline to the Gas Compressor?

• A. 600 - 1400 PSIG
• B. 600 - 1000 PSIG
• C. 125 - 350 PSIG
• D. 1000 - 1400 PSIG

Answer: (A)

Gas in interstate transmission lines is kept at high pressure to move it efficiently over long distances. Transmission systems usually operate in a broad range that starts around 600 psi and can go up to about 1400 psi (PSIG). Gas from wells is injected into these high‑pressure mains and then routed to compressor stations where the pressure is boosted or maintained to keep the flow moving. That’s why the typical pressure range for sending gas from wells through the Interstate Pipeline to the Gas Compressor is 600–1400 PSIG. The other options fall outside this common transmission range: they’re either too low for long‑distance movement (125–350 PSIG), or omit part of the transmission range (600–1000 PSIG) or the upper portion (1000–1400 PSIG) that transmission lines may experience.
