Experimental Investigation on Propagation Behavior of Hydraulic Fractures in Coal Seam during Refracturing

Experimental Investigation on Propagation Behavior of Hydraulic Fractures in Coal Seam during Refracturing

Refracturing is an effective technology for reinstituting a percolation path and improving the fracture conductivity in coal measure strata. Hydraulic fracture (HF) propagation is complicated due to the presence of cleats and stress change caused by pore pressure changes. Many scholars have studied...
