... that the diameter of the proppants is equal to the width of the cleat opening during injection, and that the individual proppant particles are not touching each other. Biot's coefficient (α) is equal to 1 (α=1). Fluid injection model To determine the permeability and cleat opening during fluid injection...

... Abstract The coal permeability declines due to fracture closure during the production and pressure depletion. The recently proposed technique for stimulation of natural coal cleats consists of the injection of microsized high-strength particles into a coal natural fractured system below...

... challenges such as green-house-gas (ghg) emission, huge amount of fuel and water consumption, liquid and solid wastes disposal. The objective of this study is to investigate an effective and efficient upgrading process by adding decalin as hydrogen donor, water and various type nanometal particles (40-500 nm...
