The oil & gas infrastructure market is being shaped by the interaction of NOC field-development programs, LNG supply-chain construction, and energy-security-led gas investment. These demand sources favor long-cycle, technically complex projects, while refinery rationalization in advanced economies and oil-price sensitivity continue to constrain portions of new-build investment.

GMI Analyst View

Our discussions with senior O&G infrastructure project executives and industry analysts indicate the market generated approximately USD 322.5 billion in revenue in 2022. The subsequent investment cycle has been defined by renewed NOC development activity, higher sustaining-capital needs at mature fields, and a widening set of gas infrastructure projects tied to supply security.

Oil & Gas Infrastructure Market Trends, Growth Drivers & GMI Forecast Outlook

LNG construction backlogs, NOC capital-program execution, and gas-security mandates are advancing demand across the infrastructure value chain. The outlook remains differentiated by asset class: gas processing, liquefaction, transmission, and storage have stronger project visibility than discretionary oil-focused greenfield developments and mature-market refinery additions.

Key Drivers

Driver Evidence signal Market-demand implication GMI forecast condition
LNG export infrastructure build-out Nearly 290 bcm per year of new LNG export capacity is under construction from projects that have reached FID and are set to come online through 2030 [1] Construction-phase EPC revenues for liquefaction trains, gas pre-treatment facilities, FLNG vessels, storage tanks, and loading jetties are advancing toward a multi-year peak, concentrating execution demand among a small group of capable EPCI contractors and specialized equipment manufacturers Accelerated Export Terminals segment revenue growth supports above-average market performance in 2026–2028; contractor concentration in large-scale LNG EPC is a scheduling wildcard
Field decline reinvestment imperative Approximately USD 570 billion in global upstream oil and gas investment in 2025 sustains demand for wellheads, artificial lift systems, separators, compression, and field gathering infrastructure [2] A substantial portion of upstream spend is directed at slowing production decline at existing fields, creating a recurring, relatively price-insensitive revenue base for surface equipment, gathering, and processing infrastructure that underpins market resilience across Brent price cycles Sustaining capital revenue provides a durable floor for the Upstream segment's contribution to overall market growth, reinforcing the 4.2% CAGR baseline even during periods of new-build deferral
Energy security mandates driving gas midstream expansion Government-mandated gas pipeline and LNG import terminal diversification programs across Europe and Asia, supported by multi-year NOC procurement frameworks and state-backed financing National gas grid extensions, cross-border pipeline interconnections, and emergency FSRU deployment programs generate midstream infrastructure demand in policy-protected markets where investment is decoupled from short-cycle commodity price signals Reduces cyclicality in global midstream capex, anchoring baseline infrastructure revenue through 2030 and supporting the Midstream segment's share expansion through the forecast period

Evidence anchors use cited external data; demand implications and forecast conditions represent GMI analysis.

The LNG build-out is increasing demand for liquefaction trains, pre-treatment systems, cryogenic equipment, compression, marine facilities, and specialist construction services. Parallel developments in North America and the Middle East also intensify competition for execution capacity, fabrication slots, and experienced project-management teams.

Field-decline management creates a different demand pattern. Operators can defer some large expansion programs, but sustaining production still requires wellhead replacement, artificial lift, separation, compression, gathering, and processing work. This recurring investment supports equipment suppliers and service contractors even when new project sanctioning becomes more selective.

Energy-security policies are extending gas investment beyond short-cycle commodity economics. Pipeline interconnections, import facilities, strategic storage, and domestic grid expansion increasingly rest on policy-backed procurement and sovereign funding structures, strengthening the market's midstream demand base.

Key Restraints

Restraint Evidence signal Market-demand implication GMI forecast condition
Oil price-driven E&P capex deferral Global upstream oil investment declined approximately 6% in 2025, the first year-on-year fall since the pandemic-era low, led by sharp cutbacks in U.S. tight-oil programs as lower prices challenged well-level profitability [2] Deferred upstream new-build programs reduce orders for surface equipment, new wellheads, field gathering expansions, and sustaining capital programs in higher-cost basins, disproportionately affecting North America and certain European markets Primary bear-case risk to market; sustained Brent below USD 60/bbl over multiple quarters could reduce forecast CAGR to approximately 2.8–3.2%, compressing Upstream segment revenues in 2027–2029
Materials cost escalation and permitting constraints North American onshore oil and gas pipeline capex for 2025–2029 is projected at USD 128 billion, reflecting structurally higher project costs from steel tariffs, contractor dayrate inflation, and protracted permitting timelines [3] Construction cost increases compress project economics and incentivize operators to substitute greenfield pipeline development with brownfield debottlenecking, lateral extensions, and long-term O&M contract renewals, slowing capacity-addition velocity Moderates pipeline new-build volume in North America relative to Asia and Middle East, creating regional mix shift within the Midstream segment that benefits lower-cost jurisdictions through the forecast period
Energy transition and advanced-economy downstream constraint EU Green Deal refinery rationalization policy with legally binding emissions-reduction schedules is driving accelerating refinery closure decisions in Western Europe, concentrating incremental downstream capital toward Asia Pacific and GCC markets Structural decline in European downstream infrastructure investment reduces growth prospects for European-focused EPC contractors and refinery equipment suppliers, while shifting the demand center of gravity for Downstream segment revenue toward Asian refinery upgrades and GCC integrated complex expansions European downstream capex decline is structurally embedded in the 2029–2035 forecast moderation phase; global Downstream segment impact is partially offset by Asia and Middle East capacity additions

Evidence anchors use cited external data; demand implications and forecast conditions represent GMI analysis.

Oil-price uncertainty is most consequential for large, high-cost upstream developments that require confidence in long-term project economics. Deepwater facilities, arctic systems, and extensive greenfield gathering networks are particularly exposed to delayed approvals, with equipment orders and contractor utilization typically weakening after capex reductions become visible.

Cost inflation and permitting friction introduce a separate constraint. In constrained pipeline corridors, operators may prioritize compression upgrades, debottlenecking, lateral extensions, or renewals of existing operating arrangements rather than sanctioning new greenfield systems. That substitution protects portions of service and revamp demand but limits capacity-addition volume.

GMI Analyst View

We see a bifurcated infrastructure cycle. Committed LNG, gas-processing, transmission, and import projects can sustain activity despite short-cycle oil-price volatility, whereas discretionary upstream new-build spending remains more exposed to capital discipline. This distinction is changing both the geographic mix of demand and the capabilities required to capture it.
