Vietnam Oil And Gas Upstream Market Trends and Insights

Increasing Crude Oil Prices

Brent stability above USD 70 per barrel underpins the redevelopment of mature offshore fields, once hampered by high lifting costs. Operators now sanction enhanced-oil-recovery pilots in fractured reservoirs and justify long-reach sidetracks that increase incremental output without requiring new green-field infrastructure. PetroVietnam's 2025 investment surge underscores renewed confidence in project economics, yet price support alone cannot counterbalance geological depletion. The Vietnam oil and gas upstream market, therefore, relies on both cost discipline and technology adoption to sustain margins.

Rising Domestic Gas Demand for Power

Electricity consumption is growing at an annual rate of 8%, and government policy mandates the retirement of coal between 2030 and 2040, creating an assured outlet for offshore gas. Decree 100/2025 compels power developers to source domestic gas under long-term contracts, stabilizing cash flows for upstream investors. Integrated projects, such as Ca Voi Xanh, exemplify the shift, pairing 3 GW of capacity with dedicated subsea supply and reducing LNG import exposure. The Vietnam oil and gas upstream market, therefore, aligns increasingly with downstream power strategies.

Complex Permitting and Bureaucracy

Multi-agency approvals can stretch final-investment-decision timelines by more than a year, inflating overhead on marginal prospects. High compliance costs weigh heavily on smaller operators in the Vietnam oil and gas upstream market, prompting some to defer projects or seek alliances that share regulatory engagement burdens.

Other drivers and restraints analyzed in the detailed report include:

2. Digital Subsurface Imaging Adoption
3. South China Sea Territorial Disputes

Segment Analysis

Offshore developments generated 77.25% of 2025 revenue and are expected to post a 5.84% CAGR through 2031, underscoring their centrality to the Vietnam oil and gas upstream market. The depths of 50-200 meters in Nam Con Son and Cuu Long host the bulk of the remaining reserves, requiring higher-specification rigs, subsea tie-backs, and floating processing units. Record 3-km horizontal sections drilled with axial-oscillation tools demonstrate how innovation offsets basement hardness.

Growth relies on integrated gas hubs connected to shore-based power plants, which monetize output through first oil capacity payments rather than volatile commodity pricing. First-oil at Dai Hung Phase 3-flowing 6,000 bpd ahead of schedule-illustrates project-management maturation and validates shared-infrastructure models that suppress unit costs. Even so, crew shortages and weather downtime complicate schedules, demanding robust contingency planning across the Vietnam oil and gas upstream industry.

Onshore acreage, constrained by urban expansion and the decline of mature fields, contributes modest and stable volumes but attracts limited new capital. Operators favor low-cost workovers and water-alternating-gas schemes to sustain plateaus; yet, the resource upside remains marginal compared to offshore prospects. Thus, offshore execution excellence will continue to determine value creation within the Vietnam oil and gas upstream market.

Natural gas accounted for 59.65% of 2025 revenue and is forecast to grow at a 6.02% CAGR, solidifying its dominance in the Vietnam oil and gas upstream market. Output is slated to increase from 8 bcm in 2025 to more than 20 bcm by 2034, as Ca Voi Xanh, Block B, and Nam Du/U Minh ramp up production. Gas sale agreements featuring 80 mmcfd take-or-pay terms ensure predictable cash flows and facilitate project financing.

Crude oil, although still essential for refinery feedstock, is facing a gradual decline due to reservoir depletion and limited success in discoveries. Condensate streams linked to gas developments provide high-value naphtha for the petrochemical industry, partly offsetting oil volume erosion. The Vietnam oil and gas upstream industry is increasingly rewarding operators capable of orchestrating entire gas value chains, from subsea wellheads to power-plant burner tips.
