At present, the world's energy mainly relies on burning fossil fuels (coal, oil, natural gas). The higher the energy consumption, the more it will affect the sustainable development of human society. problem); second, because fossil fuels are non-renewable, resources will eventually be exhausted. China is the world's largest energy consumer, but China's energy and mineral endowment is characterized by rich coal, lack of oil, and little gas. In 2021, China's dependence on foreign crude oil will reach 72%, and natural gas will reach 46%. China's energy security issues are prominent.

Unconventional oil and gas reserves are abundant. It is estimated that the global coalbed methane resources may exceed 260 trillion cubic meters, and the amount of oil shale converted into shale oil can reach more than 400 billion tons. From the global oil shale discovery and exploration To some extent, this is still a very conservative figure. According to a study by the U.S. Geological Survey in 2004, the recoverable resources of oil sands oil in the world are 103.51 billion tons, accounting for about 31.96% of the world's total recoverable oil resources, second only to oil sands oil with 151.4 billion tons of recoverable resources. conventional oil. The world's heavy oil resources are about 69 billion tons. The natural gas hydrate resources are also huge. It is estimated that the global natural gas hydrate methane resources are more than 6,000 trillion cubic meters.

Due to the complex geological structure of unconventional oil and gas reservoirs, the geological exploration and development theories and conventional oil and gas development techniques that have been mastered cannot be fully applied to unconventional oil and gas resources. Although the reserves of unconventional oil and gas resources are very large, their development is still at the beginning stage. my country has considerable unconventional oil and gas reserves, but the exploration and development of unconventional oil and gas is still in its infancy. In recent years, the development and utilization of shale gas and oil shale are being vigorously promoted.

Unconventional oil and gas resources mainly include coalbed methane, shale gas, tight sandstone gas, shale oil, ultra-heavy oil, oil sands, gas hydrate and so on, and they are playing an increasingly important role in the world’s energy structure at present. However, due to the complicated geological conditions and ultra-low permeability of unconventional oil and gas reservoirs, some traditional development techniques are not suitable and mature in these reservoirs, leading to low oil or gas production, serious environmental pollution and other urgent problems. Therefore, it is necessary to strengthen the basic theoretical research of unconventional oil and gas to find high-quality resources to optimize and develop technologies to accelerate the extraction of unconventional oil and gas resources. 

This international conference focuses on the sustainable development of unconventional oil and gas resources, recent advances, and the challenges they are facing for sustainability. We aim to bring together researchers in the aforementioned fields to highlight the current development of new techniques, to exchange the latest understanding of the underlying mechanisms, to present advanced algorithms for modeling, and to facilitate collaboration between researchers in different fields.
