東南亞上游油氣市場：市場佔有率分析、產業趨勢與統計及成長預測（2026-2031年）

據 Mordor Intelligence 稱，東南亞上游油氣市場在 2025 年的價值為 284.7 億美元，預計到 2031 年將達到 391.6 億美元，而 2026 年為 300.2 億美元，預測期內（2026-2031 年）的複合年成長率為 5.45%。

本報告按部署區域（陸上和海上）、資源類型（石油和天然氣）、油井類型（傳統型和傳統型）、服務（探勘、開發和生產以及退役）和地區（印尼、馬來西亞、泰國、越南、菲律賓、新加坡、緬甸和其他東南亞國家）進行分類。

東南亞上游油氣市場趨勢與洞察

電力和工業部門區域天然氣需求激增

預計到2030年，電力和工業領域的天然氣消費量將達到2,100億立方米，比目前水準成長45%。印尼國家電力公司（PLN）計畫新增20.9吉瓦的燃氣發電裝置容量，而馬來西亞的市場改革則將天然氣定位為太陽能和風能併網的優先調整燃料。泰國和新加坡石化產業的擴張將提振原料需求，並鞏固未來幾十年的需求前景。這種對天然氣的結構性需求正推動上游領域積極開發高二氧化碳含量儲存，並採用碳捕集模組。因此，營運商在首次投產前就簽訂了長期銷售契約，從而降低了數十億美元的投資風險，並支持了東南亞上游油氣市場的發展。

深海天然氣田的發現和計劃中的最終投資決定（FID）

位於水深超過1500公尺的印尼Geng North氣田（儲量2.5兆立方英尺）和馬來西亞Kasawari氣田（儲量3.3兆立方英尺）是全球最重要的深海天然氣發現之一。 BP公司批准了價值70億美元的Tangguh Ubadari項目，並承諾投資越南B區塊，這表明投資者對海底天然氣生產、浮體式天然氣（FLNG）和碳捕集與封存（CCS）一體化充滿信心。深海氣田的出現正在改變天然氣供應格局，使其不再依賴成熟的大陸棚資產，並為高壓、高二氧化碳排放的開發樹立了本地工程的標竿。隨著各國電網向天然氣發電轉型，這些發現正在推動新的探勘，並增強東南亞上游油氣市場的成長前景。

成熟淺海油田產量迅速下降

上世紀八、九十年代安裝的大陸棚資產目前正面臨年產量下降8%至12%的困境，原因是儲存壓力下降以及設施使用壽命超過設計年限。光是在印度尼西亞，就有超過630座海上平台在運作，其中許多平台已運行超過40年。更新項目往往難以克服資金籌措障礙，迫使業者提前停產。這種加速停產的趨勢嚴重影響了短期液態烴產量，並限制了東南亞上游油氣市場的成長潛力。

細分市場分析

到2025年，三分之二的收入將來自海上作業，隨著營運商批准建造超深海天然氣樞紐，預計到2031年，該領域將以5.98%的複合年成長率成長。東南亞上游油氣市場中海上領域的市場規模預計將在2026年達到198.2億美元，這反映了印尼「Gen North」和馬來西亞「Kasawali」FPSO的安裝所帶來的發展勢頭。浮體式生產設施、海底壓縮設施和碳捕集與封存（CCS）模組如今已成為關鍵組成部分，使得先前難以開發的高二氧化碳含量儲存得以商業化。

儘管陸上投資佔有率較小，但對預測性維護和儲存建模的投資正在提高蘇門答臘和泰國現有陸上油田的採收率。人工智慧驅動的最佳化技術已將殼牌馬來西亞資產的停機時間減少了15%至20%，有助於抵銷自然遞減的影響。隨著深海開發持續加速，鑽機和船舶的供應限制將影響專案的實施順序，預計東南亞上游油氣市場中海上承包商的優勢將持續保持。

天然氣以8.08%的複合年成長率位居榜首，預計到2031年將超過碳氫化合物成長的一半。電力公司脫碳義務和石化產業的擴張正在推動基本負載需求，而對液化天然氣進口日益成長的依賴促使各國政府推動國內天然氣貨幣化。預計到2031年，天然氣在東南亞上游油氣市場中的構成比將從2026年的137.5億美元增至202.9億美元。

原油依然重要，預計到2025年將佔市場佔有率的54.20%，但未來的成長預計將集中在富含天然氣且具備二氧化碳捕集與儲存（CCS）能力的儲存藏上。馬來西亞國家石油公司（PETRONAS）的Kassawari第一階段計畫每年可實現330萬噸的二氧化碳捕集能力，將酸性天然氣轉化為盈利項目。儘管液態烴產量逐漸下降，但強勁的區域天然氣價格和政策支持為投資提供了立足點。

第7章 市場機會與未來展望

According to Mordor Intelligence, the southeast asia oil and gas upstream market size was valued at USD 28.47 billion in 2025 and estimated to grow from USD 30.02 billion in 2026 to reach USD 39.16 billion by 2031, at a CAGR of 5.45% during the forecast period (2026-2031).

This report is Segmented by Location of Deployment (Onshore and Offshore), Resource Type (Crude Oil and Natural Gas), Well Type (Conventional and Unconventional), Service (Exploration, Development and Production, and Decommissioning), and Geography (Indonesia, Malaysia, Thailand, Vietnam, Philippines, Singapore, Myanmar, and Rest of Southeast Asia).

Southeast Asia Oil And Gas Upstream Market Trends and Insights

Surging Regional Gas Demand for Power & Industry

Natural gas consumption across the power and industrial sectors is forecast to reach 210 billion m3 by 2030, a 45% increase over current levels. Indonesia's PLN plans 20.9 GW of new gas-fired capacity, and Malaysia's market reforms treat gas as the preferred balancing fuel for solar and wind integration. Petrochemical expansions in Thailand and Singapore will lift feedstock needs, ensuring multi-decade demand visibility. This structural call on gas underpins aggressive upstream sanctioning of high-CO2 reservoirs that embed carbon-capture modules. Consequently, operators secure long-term sales contracts before first gas, de-risking multibillion-dollar investments and supporting the Southeast Asia oil and gas upstream market.

Deep-Water Gas Discoveries & Planned FIDs

Indonesia's Geng North (2.5 TCF) and Malaysia's Kasawari (3.3 TCF) rank among the world's most consequential deep-water finds, located in waters exceeding 1,500 m depth. BP's USD 7 billion Tangguh Ubadari sanction and Vietnam's Block B commitment illustrate investor confidence in subsea production, floating LNG, and CCS integration. Deep-water hubs shift the supply map away from maturing shelf assets and set local engineering benchmarks for high-pressure, high-CO2 developments. As national grids shift toward gas, these discoveries encourage fresh frontier exploration, reinforcing the outlook for growth in the Southeast Asia oil and gas upstream market.

Rapid Decline of Mature Shallow-Water Oil Fields

Shelf assets installed in the 1980s and 1990s now face annual decline rates of 8-12% as reservoir pressure falls and facilities surpass their design life. Indonesia alone operates more than 630 offshore platforms, many of which are over 40 years old. Replacement projects often fail to clear capital hurdles, prompting operators to abandon them prematurely. Such accelerated shut-ins weigh on near-term liquids output and cap upside to the Southeast Asia oil and gas upstream market.

Other drivers and restraints analyzed in the detailed report include:

1. Enhanced Fiscal Terms & New PSC Licensing Rounds
2. Mid-Size Asset Divestments by IOCs Opening Opportunities for NOCs
3. Global Rig/Sub-Sea Equipment Tightness Stretching Project Schedules

Segment Analysis

Offshore activities generated two-thirds of 2025 revenue, and the segment is forecast to compound at a 5.98% CAGR through 2031 as operators sanction ultra-deep gas hubs. The Southeast Asia oil and gas upstream market size for offshore reached USD 19.82 billion in 2026, reflecting momentum from Indonesia's Geng North and Malaysia's Kasawari FPSO installations. Floating production systems, subsea compression, and CCS modules are now integral, enabling the commercialization of previously stranded high-CO2 accumulations.

Onshore spending holds a smaller share, but investments in predictive maintenance and reservoir modeling lift recovery from legacy Sumatra and Thai onshore blocks. AI-enabled optimization reduced downtime 15-20% on Shell's Malaysian assets, helping offset natural declines. As the deep-water drive continues, rig and vessel bottlenecks will dictate project sequencing and preserve the premium enjoyed by offshore contractors within the Southeast Asia oil and gas upstream market.

Natural gas logged the fastest 8.08% CAGR and is expected to surpass half of incremental hydrocarbon volumes by 2031. Utility decarbonization mandates and petrochemical expansions lift baseload demand, while LNG import dependence prompts governments to monetize domestic gas. The natural-gas component of the Southeast Asia oil and gas upstream market is expected to increase from USD 13.75 billion in 2026 to USD 20.29 billion by 2031.

Crude oil remains important, holding a 54.20% share in 2025, but incremental growth centers on gas-rich reservoirs with CCS readiness. PETRONAS's Kasawari Phase 1 integrates 3.3 million tonnes per year of carbon-capture capacity, turning sour gas into a bankable project. Strong regional gas prices and policy support sustain the investment thesis, even as liquids output gently declines.
