Porosity and permeability are much lower in tight formation (e.g., shale, tight sandstone, chalk, and coal seam) compared with conventional formations; this is due to the small pore size and lack of connectivity observed in tight formation. The recent advanced imaging facilities make it possible to identify pore and mineral distribution at a nano-scale. The mechanism of hydrocarbon accumulation and extraction in tight formation is still lacking proper investigation.

Tight formation has gathered tremendous pace around the world to meet the global energy demand. A thorough investigation of hydrocarbon migration and extraction in tight formation will help us to improve our reserves evaluation and screen the most efficient strategies to develop these reservoirs.

This Special Issue emphasizes the fundamental scientific innovation on experimental and mathematical multiscale modelling of hydrocarbon migration and extraction in tight formation, with an emphasis on contributions that increase the basic understanding of hydrocarbon accumulation, reservoir trapping mechanics, and novel hydrocarbon extraction techniques in tight formation. We invite authors to contribute original research and critical review articles related to all aspects of hydrocarbon migration and extraction in tight formation by means of theoretical, numerical modelling, and experimental approaches.

Potential topics include but are not limited to the following:

• Tight formation characterization
• Reserve evaluation in tight formation
• Hydrocarbon accumulation and migration in tight formation
• Fluid flow mechanisms in tight formation
• Stimulation in tight formation
• Enhance hydrocarbon recovery in tight formation
