|---|---|
| 1 | Were it not for OPEC+’s disciplined compliance, Brent would have likely breached the $110 threshold already. |
| 2 | The industry-wide underinvestment since 2015 is now manifesting itself in a markedly tighter supply-demand balance. |
| 3 | Had carbon border adjustment mechanisms implemented earlier, European refining margins would not have eroded so sharply. |
| 4 | Neither the IEA’s net-zero by 2050 scenario nor OPEC’s outlook envisage peak oil demand before the mid-2030s. |
| 5 | Scope 3 emissions, accounting for roughly 85% of an integrated major’s footprint, remain stubbornly difficult to abate. |
| 6 | It is imperative that operators prioritise near-field tie-backs over greenfield developments wherever feasible. |
| 7 | The fiscal breakeven price for several Gulf producers now lies uncomfortably close the prevailing Brent forward curve. |
| 8 | Were spare capacity to fall below 2 million barrels per day, volatility would almost certainly ensue. |
| 9 | Many analysts contend that the energy transition will proceed far more gradually than previously anticipated. |
| 10 | Only by aggressively pursuing CCUS and nature-based solutions can oil companies credibly claim net-zero alignment. |
| 11 | The substitution effect between natural gas and renewables is proving far less pronounced than modellers had assumed. |
| 12 | Had regulators not relaxed flaring restrictions, associated gas utilisation rates would have risen considerably faster. |
| 13 | It stands to reason that short-cycle unconventional production will continue cushioning price spikes for years to come. |
| 14 | The levelised cost of green hydrogen is widely expected falling below $2/kg by the early 2030s in optimal locations. |
| 15 | Neither peak oil demand forecasts nor energy investment outlooks should be taken at face value without rigorous stress-testing. |
| 16 | Were it not the case of persistently elevated finding and development costs, Permian growth would have already plateaued. |
| 17 | The industry is increasingly cognisant of the fact that stranded asset impairments could reach hundreds of billions. |
| 18 | Only after the 2022 energy crisis did policymakers fully appreciate how fragile diversified supply chains really are. |
| 19 | It is high time that national oil companies divest non-core downstream assets so as focus capital on upstream renewal. |
| 20 | The pace of electrification in heavy industry is nowhere near sufficient offsetting the growth in process emissions. |
| 21 | Had fiscal terms remained unchanged, several large deep-water projects would have been deemed sub-economic. |
| 22 | The so-called ‘just transition’ remains more aspiration than actionable policy in most producing jurisdictions. |
| 23 | Not until carbon pricing reaches triple-digit levels will CCUS become broadly competitive with unabated production. |
| 24 | It is doubtful whether voluntary corporate net-zero targets will survive regulatory scrutiny much longer. |
| 25 | Were demand for petrochemical feedstocks not so resilient, refining utilisation rates would already be in structural decline. |
| 26 | The extent to which AI and digital twins can unlock incremental recovery remains hotly debated among reservoir engineers. |
| 27 | Only through large-scale retrofitting of existing LNG trains can brownfield capacity expansions be delivered cost-effectively. |
| 28 | It beggars belief that some operators still flare billions of cubic metres annually despite mature monetisation technologies. |
| 29 | Had geopolitical risk premia not receded so quickly in 2025, long-dated futures would still be trading in significant backwardation. |
| 30 | The narrative that renewables will render hydrocarbons obsolete within two decades is increasingly difficult defending. |
| 31 | Were upstream capex not reined in so aggressively post-2014, today’s supply tightness would be far less acute. |
| 32 | It is no coincidence that countries with the highest fiscal breakevens are also the most vocal OPEC+ quota enforcers. |
| 33 | Not a single major forecaster correctly anticipated the speed and scale of post-pandemic demand rebound in 2021–22. |
| 34 | The notion of ‘energy addition’ rather ‘energy transition’ better characterises current global supply dynamics. |
| 35 | Were methane intensity targets made legally binding, upstream GHG emissions would fall far more rapidly. |
| 36 | It remains to be seen whether blue hydrogen will carve out a meaningful niche or be eclipsed by green. |
| 37 | Only by embracing hybrid power solutions can offshore platforms meaningfully reduce Scope 1 emissions intensity. |
| 38 | The IEA’s insistence that no new oil and gas fields be approved is widely regarded as detached from reality. |
| 39 | Had SAF mandates been introduced five years earlier, sustainable feedstock supply chains would be far more mature today. |
| 40 | It is becoming increasingly apparent that volumetric EUR estimates systematically overstate recovery in tight oil plays. |
| 41 | Were carbon removal credits subjected to stricter additionality tests, their market price would likely collapse. |
| 42 | The dichotomy between security of supply and net-zero imperatives grows ever more difficult reconciling. |
| 43 | Not until physical traded LNG hubs achieve sufficient liquidity will Asia fully escape oil-indexation legacies. |
| 44 | It defies economic logic that some governments continue subsidising fossil fuels at scale in 2026. |
| 45 | Were the Permian’s decline curves steeper than currently modelled, WTI would already be pricing in structural scarcity. |
| 46 | The industry’s narrative of being ‘part of the solution’ rings increasingly hollow absent concrete abatement progress. |
| 47 | Only once CBAM phases reach full stringency will European importers feel meaningful carbon cost exposure. |
| 48 | It is far from certain that floating LNG will remain competitive once green hydrogen derivatives reach commercial scale. |
| 49 | Had OPEC+ not unwound production restraint so cautiously, global inventories would have built much faster in 2025. |
| 50 | The assumption that demand will peak this decade is now being quietly revised by even formerly hawkish forecasters. |

Chúng quan trọng vì: (1) giúp học viên đọc hiểu và phân tích văn bản chuyên ngành phức tạp; (2) hỗ trợ viết essay/report về năng lượng bền vững, energy transition; (3) tăng khả năng sử dụng collocation chính xác và thảo luận chuyên sâu (chiếm ~45% từ vựng ngành dầu khí theo Cambridge English for Oil & Gas và IELTS Academic 7.5+).
