With the deepening of theoretical understanding and the progress of exploration and development techniques, a series of major breakthroughs have been made in the global exploration and development of unconventional oil and gas. Global unconventional oil and gas production is growing rapidly, and its role in global energy supply is becoming increasingly prominent. Unconventional oil and gas reservoirs have poor physical properties, generally with porosities of 2%-10% and permeabilities of (0.001-1)×10-3 µm2. The basic types include tight sandstone, mud shale, tight carbonate etc. Unconventional oil and gas resources are very rich, and it is necessary to conduct in-depth research on provenance analysis, sediment transport, reservoir evaluation and geo-energy.

The purpose of this Research Topic is to provide operational evaluation ideas for unconventional resource prediction through the study of unconventional reservoir provenance analysis, sediment transport, reservoir evaluation and geo-energy, and ultimately serve oil and gas exploration practice. The different provenance controls the distribution of sedimentary facies in the vertical and lateral directions, which in turn control the spatial distribution of the grain size and clastic composition. The study of provenance analysis and sediment transport can integrate tectonics, climate, provenance lithotypes, transport dynamics, and burial diagenesis, which can provide a comprehensive understanding of unconventional reservoirs. The modelling of unconventional reservoirs is mainly aimed at reservoirs with original reservoirs tight and generally no natural industrial output, requiring artificial reconstruction, a large number of horizontal wells or branch wells and other targeted mining technologies to improve productivity. The modeling of unconventional reservoir mainly uses horizontal well data. Different from conventional reservoir modeling, the modelling of unconventional reservoir involves sweet spot characterization and artificial fracture establishment.

This Research Topic will focus on provenance analysis, sediment transport, reservoir evaluation, and geo-energy of unconventional reservoirs. It will be primarily devoted to research papers and review papers. Pioneering research papers in the field of experimental and numerical simulation are encouraged to submit their work. The scope includes but are not limited to:
• Provenance lithotype and sediment transport pathways;
• Diagenesis and reservoir quality;
• Diagenesis numerical simulation and seismic diagenetic facies;
• Data processing and application;
• Implication of machine learning and artificial intelligence to trace sediment transport;
• Controlling effect of provenance on ore-bearing reservoirs and deposits;
• Formation mechanism of sedimentary-type deposits (iron, uranium, bauxite, etc.).
