The Global Oil & Gas Landscape
The global oil and gas industry generates approximately $4 trillion in annual revenue, employing 12 million people directly and supporting hundreds of millions of livelihoods indirectly. Despite the accelerating energy transition, hydrocarbons will constitute 50-55% of the global primary energy mix through 2040 according to the International Energy Agency’s World Energy Outlook, with natural gas playing an increasingly central role as a transition fuel and LNG trade volumes projected to grow 50% by 2030.
The Gulf states — Saudi Arabia, UAE, Qatar, Kuwait, and Oman — collectively control approximately 30% of global proven oil reserves and 22% of natural gas reserves. Saudi Aramco remains the world’s most valuable company and its most profitable, generating $121 billion in net income in 2024. ADNOC has expanded from a national oil company into a diversified energy group with IPO’d subsidiaries (ADNOC Gas, ADNOC Logistics, Borouge). QatarEnergy is executing the largest LNG capacity expansion in history, doubling export capacity to 126 million tonnes per annum by 2028.
Upstream Exploration & Production
Global upstream investment reached $580 billion in 2025, recovering from the post-2020 trough but still 25% below the 2014 peak. The investment cycle is being shaped by three forces: OPEC+ production discipline (managing supply to support prices above $75/barrel), capital discipline by international oil companies (prioritising shareholder returns over production growth), and the emerging tension between energy security imperatives and climate policy commitments.
The Gulf upstream sector presents a distinct profile: production costs of $2-10/barrel (versus $15-40 for deepwater, $40-65 for oil sands) provide structural cost advantage that ensures Gulf production remains economically viable under any credible transition scenario. Saudi Aramco’s Jafurah unconventional gas programme ($110 billion committed) represents the largest unconventional gas development outside North America. ADNOC’s expanded production capacity target of 5 million barrels per day by 2027 positions the UAE as a critical swing producer.
LNG: The Transition Fuel
Liquefied natural gas is the fastest-growing segment of the hydrocarbon value chain, with global trade volumes exceeding 400 million tonnes per annum. Qatar’s North Field Expansion — the single largest energy infrastructure project under construction globally — will increase Qatari LNG capacity from 77 to 126 mtpa, cementing its position alongside Australia as the world’s pre-eminent LNG exporter. The partnership architecture (TotalEnergies, Shell, ConocoPhillips, Eni, ExxonMobil) distributes capital risk while securing diverse marketing channels.
For capital advisory firms, the LNG value chain generates mandates across project finance (upstream development), infrastructure investment (liquefaction trains, regasification terminals), shipping (LNG carrier fleet expansion), and offtake structuring (20+ year Sales and Purchase Agreements with Asian, European, and emerging market buyers). The advisory economics of a single LNG project can span a decade from feasibility through final investment decision, construction, and commissioning.
Midstream Infrastructure
The midstream sector — pipelines, processing facilities, storage, and transportation — represents the critical infrastructure connecting production to consumption. Gulf midstream assets include the world’s most strategically important crude oil pipelines (the East-West Pipeline linking Abqaiq to Yanbu, the Habshan-Fujairah pipeline providing Abu Dhabi’s crude with direct Indian Ocean access), LNG carriers (QatarEnergy’s fleet of 100+ vessels), and the refining capacity that converts crude into transportation fuels, petrochemical feedstocks, and speciality products.
The investment opportunity in midstream infrastructure is substantial: the Gulf states are diversifying crude export routes to reduce Strait of Hormuz transit dependency, building new refineries (Saudi Arabia’s Jazan Refinery and Petrochemical Complex, Kuwait’s Al Zour), and developing hydrogen transport infrastructure that will leverage existing pipeline networks.
Downstream & Petrochemical Diversification
Petrochemical diversification is a core pillar of Gulf economic strategy. SABIC (Saudi Arabia, $40 billion revenue), Borouge (ADNOC-Borealis JV, IPO’d on ADX), and EQUATE (Kuwait) are converting low-cost hydrocarbon feedstocks into polymers, fertilisers, and specialty chemicals that generate higher margins and employment than crude export. Saudi Arabia’s programme to develop downstream industrial clusters — converting crude oil into chemicals at integrated refineries like Ras Al Khair and SATORP — aims to capture three to four times the value per barrel compared to crude export.
The circular carbon economy framework — endorsed by the G20 during Saudi Arabia’s presidency — positions the Gulf states’ approach to hydrocarbons as a ‘reduce, reuse, recycle, remove’ model rather than the binary ‘produce or eliminate’ framing that characterises Western energy policy debate.
Carbon Capture, Utilisation & Storage
CCUS is central to the Gulf states’ energy transition strategy. ADNOC operates Al Reyadah, the Middle East’s first commercial-scale carbon capture facility, capturing 800,000 tonnes of CO2 annually from an Emirates Steel facility and injecting it into oil reservoirs for enhanced oil recovery. Saudi Aramco is developing the Jubail CCS hub targeting 9 million tonnes per annum by 2027. The Gulf’s depleted oil and gas reservoirs provide geological storage capacity that many other regions lack.
For institutional investors, CCUS represents a multi-billion dollar infrastructure investment opportunity that aligns with both hydrocarbon production optimisation (through EOR) and climate commitments. The ESG advisory mandate covers CCUS project development, carbon credit generation from captured emissions, and the regulatory frameworks governing carbon storage across jurisdictions.
Energy Transition Implications
The energy transition does not eliminate the oil and gas advisory mandate — it transforms it. Gulf NOCs are repositioning as integrated energy companies: Aramco is investing in renewables, hydrogen, and synthetic fuels; ADNOC has acquired Masdar (renewable energy) and is developing blue hydrogen capacity; QatarEnergy is investing in solar alongside its LNG expansion. The advisory mandate evolves from pure hydrocarbon transactions to integrated energy strategy, carbon management, and the financial structuring that connects traditional energy assets to transition capital.
Kaelo’s energy advisory practice covers the full hydrocarbon value chain — from upstream asset transactions through midstream infrastructure finance, downstream petrochemical investment, and the emerging CCUS and hydrogen mandates that connect the oil and gas sector to the energy transition.
Investment Thesis
The oil and gas investment thesis for the Gulf is straightforward: the lowest-cost producers in the world, with the strongest balance sheets, the longest reserve lives, and the most ambitious diversification strategies will be the last barrels produced and the first to capture transition opportunities. The advisory economics — M&A, project finance, JV structuring, IPO advisory for NOC subsidiaries, and the emerging green finance instruments — will persist for decades regardless of the pace of global decarbonisation.
Oil and gas in the Gulf is not a sunset industry — it is the foundation from which the world’s most consequential energy transition is being financed, managed, and executed.
