United States Oil And Gas Midstream Market Trends and Insights

LNG-led Surge in Gulf Coast Export Capacity

Operational LNG capability is expected to increase to 21.2 Bcf/d by 2028, creating the single largest draw on pipeline throughput in the US oil and gas midstream market. Venture Global's USD 28 billion Calcasieu Pass 2, featuring a 91-mile feeder line, demonstrates how each terminal triggers interstate pipeline builds and compression upgrades. Cheniere's Corpus Christi Trains 8 & 9 add more than 3 Mtpa and require USD 50-100 million per interconnection for high-pressure tie-ins. Bidirectional design becomes standard, allowing lines to reverse during maintenance or hurricane disruptions, which adds cost but boosts resiliency. Concentrated Gulf activity tightens labor and specialty steel supply, elevating capital expenditures for smaller entrants.

Permian Crude & Associated-gas Production Growth

Permian output continues to outstrip takeaway, driving the need for new gathering, processing, and long-haul capacity across crude, gas, and NGL streams. Phillips 66's USD 300 million Iron Mesa plant, starting in 2027, captures gas once flared, while Tallgrass's 2.4 Bcf/d connector to Rockies Express unlocks western markets. Integrated operators switch volumes among crude, gas, and NGL pipelines based on hub spreads, maximizing system cash flow in the US oil and gas midstream market. Flow-optimization software defers the installation of new trunklines until volumes prove to be durable. Producers favor shippers that can offer multi-commodity take-or-pay contracts, tilting negotiation leverage toward large incumbents.

Federal Permitting Bottlenecks (NEPA, Sec 401)

One-year EIS targets set by Interior reduce paperwork, but lawsuits still stall rights-of-way, resulting in delay costs of up to USD 2 million per mile. Section 401 water reviews allow states to halt projects even when federal agencies approve, thereby prolonging the queue. Energy Transfer's Lake Charles LNG extension shows how serial FERC filings become routine in the US oil and gas midstream market. Developers front-load baseline studies and community outreach, inflating pre-FID spend but safeguarding schedules. Only the largest balance sheets can absorb multi-year delays without jeopardizing credit metrics.

Segment Analysis

Pipelines supplied 44.25% of 2025 revenue for the US oil and gas midstream market and form the connective backbone among basins, processors, and docks. Capital cost averages USD 4 million per mile onshore, making trunkline investments sizable yet defensible when underpinned by 20-year take-or-pay contracts. Kinder Morgan's USD 9.3 billion backlog, two-thirds of which is dedicated to gas transmission, signals continued faith in continental grid expansion.

New builds emphasize bidirectional flow, sectionalized valves, and high-horsepower compression to swing gas between export and power-market pulls, features that older pipe lacks. Terminal infrastructure, although accounting for only 17.85% of 2025 revenue, is expected to advance at a 4.95% CAGR through 2031 as LNG and LPG docks proliferate. Calcasieu Pass 2 alone drives nearly 100 miles of new lateral pipe and twin loading berths, underscoring how each dock multiplies system spend. Storage caverns and tanks, often overlooked, yield optionality to capture shoulder-season arbitrage and to buffer ethane exports during license upheavals.
