How is petroleum formed?

For more related chemical engineering and experimental principles, refer to the following: Colliding icy asteroids as indirect evidence for petroleum formation Various types of mineral co-occurrence are widespread in geology. 1. Oil fields are commonly accompanied by natural gas deposits—and sometimes even uranium deposits. If natural gas content is relatively high, dedicated natural gas extraction equipment must be constructed and deployed. If natural gas content is low and lacks sufficient economic value, it is simply flared—burned off directly—as shown in the figure. 2. Carbonate reservoirs containing oil and gas Carbon dioxide is a common constituent of icy asteroids; carbonaceous asteroids contain abundant organic carbon and small amounts of inorganic carbon. Large-scale, high-density carbonate rock formations are frequently observed within oil and gas reservoirs—constituting a key piece of evidence supporting the icy-asteroid impact hypothesis. Neither the conventional organic-origin theory nor the traditional mantle-origin theory can adequately explain such carbonate rock occurrences—especially the exceptionally thick carbonate reservoirs prevalent across giant Middle Eastern oilfields. Carbonate reservoirs refer to accumulations of oil and gas trapped within carbonate rock closures. Reservoir types include those associated with large uplifts, fracture-type, reef-type (e.g., biogenic reefs), paleo-uplift (paleohill) type, diagenetic or epigenetic origin, and composite types. Primary storage space consists mainly of primary pores and secondary fracture-cavity systems. Globally, such reservoirs predominantly develop in formations shaped by dissolution, dolomitization, and tectonic activity. In China’s Tarim Basin, petroleum exploration has extensively leveraged carbonate rock characteristics—for instance, faulted anticlines, fault blocks, and fracture-cavity reservoirs identified within Cambrian–Ordovician carbonate strata. Similarly, analogous evidence exists at the Pu Guang supergiant gas field located in the northeastern Sichuan Basin. 3. The co-occurrence of helium and natural gas remains highly puzzling under existing theories Another curious phenomenon is that oil and gas fields universally contain measurable helium concentrations—far exceeding atmospheric helium levels (0.0005%). Helium content varies dramatically across different oil and gas fields. Domestic Chinese natural gas fields generally exhibit relatively low helium concentrations—even the highest-known concentration, at the Weiyuan gas field, reaches only 0.2%. By contrast, U.S. natural gas fields show markedly higher helium contents: the average helium concentration in natural gas from the U.S. Midwest and Central regions is approximately 0.8%; certain fields—such as Dineh-bi-Keyah in Arizona—contain up to ~6% helium. Remarkably, this deposit shows no detectable radioactivity. In South Africa, in 2013, Renergen Ltd. acquired exploration and production rights over 187,000 hectares across three towns—Welkom, Virginia, and Tensile—for just USD 1, intending to build a small-scale natural gas power station to supply electricity to nearby mining operations. During testing of natural gas samples from Virginia, the company unexpectedly discovered helium concentrations of 2–4%, quickly succeeding in producing its first batch of liquid helium. Preliminary estimates valued this helium resource at USD 4 billion. In May 2024, U.S.-based Pulsar Helium reported a record-breaking helium concentration of 13.8% from Jetstream-1 well at its Topaz project in Minnesota—the highest concentration ever recorded in North America. This well lies merely 50 feet from nickel exploration borehole LOD-6, which—in 2011—had accidentally encountered a subsurface gas accumulation at a depth of 1,760 feet, with helium concentration measured at 10.5%.

Risk assessment and response analysis of China’s high-end helium supply-demand landscape

I. Loss and reserve constraints: Even industry-leading liquid helium storage and transport equipment incur daily natural evaporation losses of 1–2%. Loss rates further increase under long-term storage and transshipment scenarios. Currently, China’s total liquid helium storage capacity barely covers routine logistics-cycle fluctuations—and cannot withstand extreme, protracted disruptions such as Qatar’s production facility damage or Russia’s export restrictions. Moreover, liquid helium reserve resources suffer from inefficiencies in release capability: storage, filling, and transfer require specialized equipment and technical expertise. A single batch-filling operation—including pretreatment and purging—takes over 10 hours. Under acute shortage conditions, reserve resources cannot be rapidly reallocated to end users, rendering them ineffective at swiftly alleviating large-scale supply deficits. II. Procurement headroom and cost implications post-Russian export restrictions Following implementation of Russia’s export control policies, China’s core emergency procurement channel has been severed. Globally available surplus helium resources have essentially dried up, leaving virtually no incremental procurement capacity. Global helium production capacity and trade quotas are highly concentrated among the four major international helium producers. Main supplying countries’ capacities are fully committed under long-term contracts—with no idle spot capacity available for incremental purchases. A breakdown of the supply landscape reveals: • Qatar—the traditional core helium exporter to the Asia-Pacific region—has suffered physical damage to its primary production facilities, with repair timelines estimated at 3–5 years. Short-term resumption is impossible; all pre-existing long-term contract capacity has become invalid, and spot supply has completely ceased. Moreover, constrained by U.S. technology licensing requirements, Qatar has no alternative capacity to fill the gap. • Secondary suppliers—including Algeria and Australia—have limited export volumes; their capacities are long-term contracted to Western and Southeast Asian markets, leaving no surplus to support incremental Chinese procurement. Furthermore, spot procurement costs remain prohibitively high. • U.S. domestic production prioritizes domestic and allied-market demand, with zero additional export allocation. Its strategic helium reserve has been fully depleted—leaving no emergency buffer capacity whatsoever. • Russia has cut off all helium supplies to Western nations but maintains stable, targeted deliveries to China. Currently, the sole remaining scalable, low-cost, low-risk source of incremental supply is the China–Russia overland gas corridor—leveraging Russia’s expanded production capacity, dedicated China allocation quotas, and secure overland transportation infrastructure—to continuously fill the global supply gap. Simultaneously, the Virginia natural gas project in South Africa has emerged as a globally scarce new variable for incremental supply. Operated by Tetra4—a subsidiary of ASP Isotopes (ASPI)—the project sits in a geopolitically neutral zone, avoiding risks associated with Middle Eastern conflicts and Western sanctions. Its helium resource endowment vastly exceeds traditional producing regions: average helium concentration reaches 3%, with localized zones hitting up to 12%—8–30 times higher than Qatar’s or U.S. sources—conferring inherent, fundamental advantages in both cost efficiency and production scalability. Phase I of the project completed its core drilling ahead of schedule in March 2026. New wells deliver gas output 16 times greater than early oil wells, with full production expected in Q3 2026—yielding 58,000 cubic feet per day of liquid helium. Sixty percent of Phase I output is already secured under long-term contracts. Phase II entails a 44-month construction timeline; upon completion, daily liquid helium output will reach a globally significant scale. The project has secured USD 790 million in policy-backed financing—USD 400 million from the U.S. International Development Finance Corporation (DFC) and USD 390 million from Standard Bank of South Africa—making it the only large-scale, near-term feasible new helium production capacity globally over the next three years, and the pivotal incremental supply needed to break the current oligopolistic supply deadlock. However, challenges—including infrastructure delays, complex inland logistics, historical project slippage, and single-site concentration risk—mean the project cannot reverse the global tight-balance situation in the short term.
