The booming unconventional oil and gas industry, encompassing gas hydrates, deep coalbed methane, shale gas, tight oil, and more, confronts formidable geophysics and petrophysics hurdles. These resources, often trapped in low-permeability rocks, require innovative drilling, completion, and enhancement techniques, necessitating a deeper understanding of geophysics and petrophysics behaviors under complex geological conditions, wellbore stability and casing design, reservoir enhancement, and production increase measures, formation pressure management and fluid flow, problems involving coupled multifield geomechanics, imaging and interpretation of complex geological structures, and multi-source data fusion and comprehensive interpretation. Understanding and solving these issues is vital for sustainable and efficient production, ensuring energy security and economic viability.

Explore the complex geophysics and petrophysics issues involved in unconventional oil and gas development in depth. This exploration aims to reveal how the microstructure of rocks and pore characteristics influence fluid flow and reservoir transformation. By optimizing drilling and fracturing parameters, as well as other engineering techniques, it is possible to improve the recovery rate of oil and gas. Simultaneously, it is crucial to ensure the safety and environmental friendliness of the extraction processes. Ultimately, these efforts provide a scientific foundation and technical support for the efficient and sustainable development of unconventional oil and gas resources.
