Mathematical model of shale expansion and deformation

The development of shale oil reservoirs is significant for the petroleum industry. Fluids in shale oil play exist in nanoscale pores, and the interaction between fluids and shale rock surface walls can lead to the expansion and deformation of the entire pore medium thus affecting the development and production of oil reservoirs. We used an organic matter (graphene) pore …
