Table 2 Classification and characteristics of continental shale oil in China.

Shale oil type Occurrence state Reservoir Exploitation technology Development conditions Status and function Medium-low maturity Retained hydrocarbons that have been generated + asphalt and solid organic matter Organic matter pore in shale and the space left by the conversion of solid organic matter Underground in situ heating conversion technology, partially mature Technical feasibility + technical economics + scale of production Technology breakthroughs will bring a large-scale increase in crude oil production and ensure national energy security Medium-high maturity Retained hydrocarbons that have been generated Organic matter pore in shale and multiple types of fractures Horizontal well + volume fracturing technology, mature Economics of production per well + economics of cumulative production Realistic, but the contribution has yet to be tested in practice
